If this is your first time using open weight models right after release, know that there are always bugs in the early implementations and even quantizations.

Every project races to have support on launch day so they don’t lose users, but the output you get may not be correct. There are already several problems being discovered in tokenizer implementations and quantizations may have problems too if they use imatrix.

So you’re going to see a lot of “I tried it but it sucks because it can’t even do tool calls” and other reports about how the models don’t work at all in the coming weeks from people who don’t realize they were using broken implementations.

If you want to try cutting edge open models you need to be ready to constantly update your inference engine and check your quantization for updates and re-download when it’s changed. The mad rush to support it on launch day means everything gets shipped as soon as it looks like it can produce output tokens, not when it’s tested to be correct.

You seem like you know what you're talking about... what inference engine should I use? (linux, 4090)

I keep having "I tried it but it sucks" issues mostly around tool calling and it's not clear if it's the model or ollama. And not one model in particular, any of them really.

by colechristensen

4/3/2026 at 3:52:34 PM

For the specific issue parent is talking about, you really need to give various tools a try yourself, and if you're getting really shit results, assume it's the implementation that is wrong, and either find an existing bug tracker issue or create a new one.

Same thing happened when GPT-OSS launched, bunch of projects had "day-1" support, but in reality it just meant you could load the model basically, a bunch of them had broken tool calling, some chat prompt templates were broken and so on. Even llama.cpp which usually has the most recent support (in my experience) had this issue, and it wasn't until a week or two after llama.cpp that GPT-OSS could be fairly evaluated with it. Then Ollama/LM Studio updates their llama.cpp some days after that.

So it's a process thing, not "this software is better than that", and it heavily depends on the model.

After spending the past few weeks playing with different backends and models, I just can’t believe how buggy most models are.

It seems to me that most model providers are not running/testing via the most used backends i.e Llama, Ollama etc because if they were, they would see how broken their release is.

Tool calling is like the Achilles Heel where most will fail unless you either modify the system prompts or run via proxies so you can inject/munge the request/reply.

Like seriously… how many billions and billions (actually we saw one >800 billion evaluation last week, so almost a whole trillion) goes into AI development and yet 99.999% of all models from the big names do not work straight out of the box with the most common backends. Blows my mind!

> It seems to me that most model providers are not running/testing via the most used backends i.e Llama, Ollama etc because if they were, they would see how broken their release is.

The models usually run fine on the server targeted backends they’re released for.

Those projects you cited are more niche. They each implement their own ways of doing things.

It’s not the responsibility of model providers to implement and debug every different backend out there before they release their model. They release the model and usually a reference way of running it.

The individual projects that do things differently are responsible for making their projects work properly.

Don’t blame the open weight model teams when unrelated projects have bugs!

by Aurornis

4/3/2026 at 5:25:43 PM

Just since I'm curious, what exact models and quantization are you using? In my own experience, anything smaller than ~32B is basically useless, and any quantization below Q8 absolutely trashes the models.

Sure, for single use-cases, you could make use of a ~20B model if you fine-tune and have very narrow use-case, but at that point usually there are better solutions than LLMs in the first place. For something general, +32B + Q8 is probably bare-minimum for local models, even the "SOTA" ones available today.

by embedding-shape

4/4/2026 at 5:39:29 AM

I haven’t tried any Qwen yet, but so far I’m sticking with gpt-oss-20B.

In terms of what I’m using, I’ve looked at anything that will fit on a MacBook Pro with 32Gb RAM (so with shared memory) - LFM2, Llama, Minstral, Ministral, Devstral, Phi, and Nemotron.

As for quantisation, I aim for the biggest that will fit while also not being too slow - so it all depends on the model. But I’ll skip a model if I can’t at least use a Q4_K_M.

Also, given that I also bump my context to at least 32K, because tooling sucks when the tooling definitions itself come close to 4096!

I can’t wait for RAM prices to come down!

by alfiedotwtf

4/3/2026 at 4:23:01 PM

I've had really good success with LMStudio and GLM 4.7 Flash and the Zed editor which has a baked in integration with LMStudio. I am able to one-shot whole projects this way, and it seems to be constantly improving. Some update recently even allowed the agent to ask me if it can do a "research" phase - so it'll actually reach out to website and read docs and code from github if you allow it. GLM 4.7 flash has been the most adept at tool calling I've found, but the Qwen 3 and 3.5 models are also fairly good, though run into more snags than I've seen with GLM 4.7 flash.

by kamranjon

4/3/2026 at 2:55:37 PM

I don’t know if any of engines are fully tested yet.

For new LLMs I get in the habit of building llama.cpp from upstream head and checking for updated quantizations right before I start using it. You can also download llama.cpp CI builds from their release page but on Linux it’s easy to set up a local build.

If you don’t want to be a guinea pig for untested work then the safe option would be to wait 2-3 weeks

by Aurornis

4/3/2026 at 10:04:45 PM

For me, LM Studio on Fedora + Gemma 4 didn't work yesterday afternoon with the release, but worked this morning after the runtimes updated. In fact - there are new runtime updates now as I check again.

by accrual

4/3/2026 at 2:52:20 PM

just use openrouter or google ai playground for the first week till bugs are ironed out. You still learn the nuances of the model and then yuu can switch to local. In addition you might pickup enough nuance to see if quantization is having any effect

by vardalab

4/3/2026 at 12:06:46 PM

In case someone would like to know what these are like on this hardware, I tested Gemma 4 32b (the ~20 GB model, the largest Gemma model Google published) and Gemma 4 gemma4:e4b (the ~10 GB model) on this exact setup (Mac Mini M4 with 24 GB of RAM using Ollama), I livestreamed it:

https://www.youtube.com/live/G5OVcKO70ns

The ~10 GB model is super speedy, loading in a few seconds and giving responses almost instantly. If you just want to see its performance, it says hello around the 2 minute mark in the video (and fast!) and the ~20 GB model says hello around 5 minutes 45 seconds in the video. You can see the difference in their loading times and speed, which is a substantial difference. I also had each of them complete a difficult coding task, they both got it correct but the 20 GB model was much slower. It's a bit too slow to use on this setup day to day, plus it would take almost all the memory. The 10 GB model could fit comfortably on a Mac Mini 24 GB with plenty of RAM left for everything else, and it seems like you can use it for small-size useful coding tasks.

4/3/2026 at 4:04:14 PM

Huge Claude user here… can someone help me set some realistic expectations if I bought a Mac mini and spun one up? I use Claude primarily for dev work and Home Lab projects. Are the open models good enough to run locally and replace the Claude workload? Or am I better off with my $20/mo Claude subscription?

by neo_doom

4/3/2026 at 4:17:41 PM

They are good for small tasks but you would not be able to use it like you use Claude and most likely be disappointed. But also, I do not know how you use claude.

There are many services online which offer hosted services for these models, my advice for anyone who is thinking about buying hardware to self host this is to try those first, that way you can get an impression of the capabilities and limitations of those models before you commit to buying hardware

by NietTim

4/3/2026 at 5:15:12 PM

Best way to find out is to buy $10 of OpenRouter credits and try the models for yourself.

From my experience doing this, they're nowhere close, but it's entertaining to check in once in a while.

by hamdingers

4/3/2026 at 6:59:00 PM

I've been playing with the open models since the original llama leak. They're getting better over time, are useful for tasks of moderate complexity and it's just cool to have a binary blob of knowledge that you can run locally without an internet connection.

However you should manage your expectations. Whatever the benchmarks say, you'll quickly realise they're not at all competing with Sonnet let alone Opus. Even the largest open weights models aren't really doing that.

by MrScruff

4/3/2026 at 4:58:42 PM

So far, I’ve found gpt-oss-20B to be pretty good agentic wise, but it’s nothing like Claude Code using its paid models.

(I haven’t tried the 120B, which I’ve read is significantly better than 20B)

by alfiedotwtf

4/3/2026 at 1:06:31 PM

I tested briefly with a MacBook Pro m4 with 36gb. Run in LM Studio with open code as the frontend and it failed over and over on tool calls. Switched back to qwen. Anyone else on similar setup have better luck?

by milchek

4/3/2026 at 1:51:43 PM

I failed to run in LM Studio on M5 with 32gb at even half max context. Literally locked up computer and had to reboot.

Ran gemma-4-26B-A4B-it-GGUF:Q4_K_M just fine with llama.cpp though. First time in a long time that I have been impressed by a local model. Both speed (~38t/s) and quality are very nice.

by internet101010

4/3/2026 at 2:47:55 PM

Tool calls falling is a problem with the inference engine’s implementation and/or the quant. Update and try again in a few days.

This is how all open weight model launches go.

by Aurornis

4/3/2026 at 1:57:30 PM

Haven't had time to try yet, but heard from others that they needed to update both the main and runtime versions for things to work.

by jasonjmcghee

4/3/2026 at 2:20:34 PM

Even with the latest version of LM Studio and the latest runtimes I find that tool use fails 100% of the time with the following error: Error rendering prompt with jinja template: "Cannot apply filter "upper" to type: UndefinedValue".

EDIT: The issue is addressed in LM Studio 0.4.9 (build 1), which auto-update wasn't picking up for me for some reason.

by abroadwin

4/4/2026 at 2:40:17 PM

Yes same experience. Goes into loop mode where is sends same command again and again, till we kill it. This was Q_8 version on lmstudio

by bicepjai

4/4/2026 at 2:01:56 AM

I can confirm that tool calls failed for me (Ubuntu server with charmbracelet/crush, if that matters)

by solaire_oa

4/3/2026 at 2:07:05 PM

M5 air here with 32gb ram and 10/10 cores. Anyone got some luck with mlx builds on oMLX so far? Not at my machine right now and would love to know if these models already work including tool calling

by anonyfox

4/3/2026 at 3:02:35 PM

The latest release v0.3.2 has partial support, generation is supported but not all special tokens are handled. I've done some personal testing to add tool calling and <|channel> thinking support. https://github.com/Yukon/omlx

by Yukonv

4/3/2026 at 5:17:30 PM

awesome man, can’t wait! And just now checked it out and indeed 0.3.2 does already work for baseline chatting with mlx versions of Gemma 4 … downloading and comparing different variants right now!

by anonyfox

4/3/2026 at 6:17:52 PM

Slightly off topic, but question for folks.

I'm hoping to replace coding with Claude Sonnet 4.5 with a model with an open source or open weights model. Are any of the models on Ollama.com cloud offering (https://ollama.com/search?c=cloud) or any of the models on OpenRouter.ai a close replacement? I know that no model right now matches the full performance and capabilities of Claude Sonnet 4.5, but I want to know how close I can get and with which model(s).

If there is a model you say can replace it, talk about how long you have been using it for, and using what harness (Claude code, opencode, etc), and some strengths and weakness you have noticed. I'm not interested in what benchmarks say, I want to hear about real world use from programmers using these models.

by jasonriddle

4/3/2026 at 6:38:26 PM

In short: no.

Nothing comes close, in my opinion. Sonnet and Opus are still the best models. The Codex variants of the GPT models are also great. I've tried MiniMax, GLM, Qwen and Kimi and for anything even remotely complex these models seriously struggle.

by dimgl

4/3/2026 at 6:40:37 PM

Thank you for the honest answer.

Yes, this is the conclusion I've come to as well. I don't want to continue supporting OpenAI nor Anthropic, but the other models don't seem to be anywhere close yet, despite the hype.

by jasonriddle

4/3/2026 at 6:26:08 PM

Yes GLM5 and KimiK2.5 are pretty close replacements for sonnet.

by scottcha

4/3/2026 at 6:43:16 PM

Haven't really tried GLM5 much but I've used 4.7 quite a bit and it was pretty far from competing with Sonnet at the time, although I saw claims online to the contrary.

by MrScruff

4/3/2026 at 6:41:43 PM

What coding harness are you using? What are some example workflows you have used either for? Have you used them only for new/simple projects or for more complicated refactoring or architecture design?

by jasonriddle

4/3/2026 at 8:50:55 PM

I use OpenCode and have just started using Nanoclaw with ClaudeCode (my coworker has a post coming on this) and sometimes ClaudeCode with Claude Code Router. I do a range of small to complex work with these but I also do drop back in to Claude Opus for some really complex things where I want it to be more autonomous.

by scottcha

4/3/2026 at 4:41:40 PM

Weird that the steps are for "Gemma 4 12b", which does not exist, and then switches to 26b midway through.

There's also a step to verify that it doesn't fit on the GPU with ollama ps showing "14%/86% CPU/GPU". Doesn't this mean you'll have really bad performance?

by spencer-p

4/3/2026 at 5:55:56 PM

The Mac mini doesn't have different memory for the CPU and GPU, so maybe that's ignorable?

by Schiendelman

4/3/2026 at 8:17:28 PM

Running 26B locally is impressive but the latency math gets rough once your doing anything beyond chat. We switched from local inference to API calls for image generation specifically because cold start + generation time on consumer hardware made it impractical for any kind of automated workflow.

Local is great for experimentation but production workloads that need to run reliably at specific times still favor API imo. That said for privacy sensitive use cases where data cant leave the machine, setups like this are invaluable.

by pwr1

4/3/2026 at 10:40:31 AM

Why is ollama so many people’s go-to? Genuinely curious, I’ve tried it but it feels overly stripped down / dumbed down vs nearly everything else I’ve used.

Lately I’ve been playing with Unsloth Studio and think that’s probably a much better “give it to a beginner” default.

by easygenes

4/3/2026 at 11:52:57 AM

Ollama is good enough to dabble with, and getting a model is as easy as ollama pull <model name> vs figuring it out by yourself on hugging face and trying to make sense on all the goofy letters and numbers between the forty different names of models, and not needing a hugging face account to download.

So you start there and eventually you want to get off the happy path, then you need to learn more about the server and it's all so much more complicated than just using ollama. You just want to try models, not learn the intricacies of hosting LLMs.

by diflartle

4/3/2026 at 2:36:04 PM

to be fair, llama.cpp has gotten much easier to use lately with llama-server -hf <model name>. That said, the need to compile it yourself is still a pretty big barrier for most people.

by flux3125

4/3/2026 at 4:55:38 PM

I started with ollama and now I'm using llama.cpp/llama-server's Router Mode that allows you to manage multiple models through a single server instance.

One thing I haven't figured out: Subjectively, it feels like ollama's model loading was nearly instant, while I feel like I'm always waiting for llama.cpp to load models, but that doesn't make sense because it's ultimately the same software. Maybe I should try ollama again to convince myself that I'm not crazy and that ollama's model loading wasn't actually instant.

by ryandrake

4/3/2026 at 9:59:09 PM

> That said, the need to compile it yourself is still a pretty big barrier for most people.

My distro (NixOS) has binary packages though...

And there's packages in the AUR (Arch), GURU (Gentoo), and even Debian Unstable. Now, these might be a little behind, but if you care that much you can download binaries from GitHub directly.

by MarsIronPI

4/3/2026 at 11:07:21 AM

Ollama got some first-mover advantage at the time when actually building and git pulling llama.cpp was a bit of a moat. The devs' docker past probably made them overestimate how much they could lay claim to mindshare. However, no one really could have known how quickly things would evolve... Now I mostly recommend LM-studio to people.

What does unsloth-studio bring on top?

by polotics

4/3/2026 at 11:14:34 AM

LM Studio has been around longer. I’ve used it since three years ago. I’d also agree it is generally a better beginner choice then and now.

Unsloth Studio is more featureful (well integrated tool calling, web search, and code execution being headline features), and comes from the people consistently making some of the best GGUF quants of all popular models. It also is well documented, easy to setup, and also has good fine-tuning support.

by easygenes

4/3/2026 at 12:50:16 PM

LM Studio isn't free/libre/open source software, which misses the point of using open weights and open source LLMs in the first place.

by xenophonf

4/3/2026 at 1:32:28 PM

Disagree, there are a lot of reasons to use open source local LLMs that aren't related to free/libre/oss principles. Privacy being a major one.

by vonneumannstan

4/3/2026 at 3:22:33 PM

If you care about privacy making sure the closed source software does not call home is a concern...

by ekianjo

4/3/2026 at 5:37:42 PM

I run Little Snitch[1] on my Mac, and I haven't seen LM Studio make any calls that I feel like it shouldn't be making.

Point it to a local models folder, and you can firewall the entire app if you feel like it.

Digressing, but the issue with open source software is that most OSS software don't understand UX. UX requires a strong hand and opinionated decision making on whether or not something belongs front-and-center and it's something that developers struggle with. The only counterexample I can think of is Blender and it's a rare exception and sadly not the norm.

LM Studio manages the backend well, hides its complexities and serves as a good front-end for downloading/managing models. Since I download the models to a shared common location, If I don't want to deal with the LM Studio UX, I then easily use the downloaded models with direct llama.cpp, llama-swap and mlx_lm calls.

Advertising, mostly.

Ollama's org had people flood various LLM/programming related Reddits and Discords and elsewhere, claiming it was an 'easy frontend for llama.cpp', and tricked people.

Only way to win is to uninstall it and switch to llama.cpp.

by DiabloD3

4/3/2026 at 4:01:57 PM

What I really don't get is why more people don't talk about LMStudio, I switched to it months ago and it seems like a straight upgrade.

Ollama user with the opposite question -- why not? What am I missing out on? I'm using it as the backend for playing with other frontend stuff and it seems to work just fine.

And as someone running at 16gb card, I'm especially curious as to if I'm missing out on better performance?

by jrm4

4/3/2026 at 3:24:07 PM

Ollama has had bad defaults forever (stuck on a default CTX of 2048 for like 2 years) and they typically are late to support the latest models vs llamacpp. Absolutely no reason to use it in 2026.

by ekianjo

4/3/2026 at 6:06:50 PM

> Ollama user with the opposite question -- why not? What am I missing out on? I'm using it as the backend for playing with other frontend stuff and it seems to work just fine.

Used to be an Ollama user. Everything that you cite as benefits for Ollama is what I was drawn to in the first place as well, then moved on to using llama.cpp directly. Apart from being extremely unethical, The issue is that they try to abstract away a bit too much, especially when LLM model quality is highly affected by a bunch of parameters. Hell you can't tell what quant you're downloading. Can you tell at a glance what size of model's downloaded? Can you tell if it's optimized for your arch? Or what Quant?

`ollama pull gemma4`

(Yes, I know you can add parameters etc. but the point stands because this is sold as noob-friendly. If you are going to be adding cli params to tweak this, then just do the same with llama.cpp?)

That became a big issue when Deep Seek R1 came out because everyone and their mother was making TikToks saying that you can run the full fat model without explaining that it was a distill, which Ollama had abstracted away. Running `ollama run deepseek-r1` means nothing when the quality ranges from useless to super good.

> And as someone running at 16gb card, I'm especially curious as to if I'm missing out on better performance?

I'd go so far as to say, I can *GUARANTEE* you're missing out on performance if you are using Ollama, no matter the size of your GPU VRAM. You can get significant improvement if you just run underlying llama.cpp.

Secondly, it's chock full of dark patterns (like the ones above) and anti-open source behavior. For some examples:

1. It mangles GGUF files so other apps can't use them, and you can't access them either without a bunch of work on your end (had to script a way to unmangle these long sha-hashed file names) 2. Ollama conveniently fails contribute improvements back to the original codebase (they don't have to technically thanks to MIT), but they didn't bother assisting llama.cpp in developing multimodal capabilities and features such as iSWA. 3. Any innovations to the do is just piggybacking off of llama.cpp that they try to pass off as their own without contributing back to upstream. When new models come out they post "WIP" publicly while twiddling their thumbs waiting for llama.cpp to do the actual work.

It operates in this weird "middle layer" where it is kind of user friendly but it’s not as user friendly as LM Studio.

After all this, I just couldn't continue using it. If the benefits it provides you are good, then by all means continue.

IMO just finding the most optimal parameters for a models and aliasing them in your cli would be a much better experience ngl, especially now that we have llama-server, a nice webui and hot reloading built into llama.cpp

by the_lucifer

4/3/2026 at 10:06:50 PM

> 1. It mangles GGUF files so other apps can't use them, and you can't access them either without a bunch of work on your end (had to script a way to unmangle these long sha-hashed file names)

This is what pushed me away from Ollama. All I wanted was to scp a model from one machine to another so I didn't have to re-download it and waste bandwidth. But Ollama makes it annoying, so I switched to llama.cpp. I did also find slightly better performance on CPU vs Ollama, likely due to compiling with -march=native.

> (they don't have to technically thanks to MIT)

Minor nit: I'm not aware of any license that requires improvements to be upstreamed. Even GPL just requires that you publish derivative source code under the GPL.

by MarsIronPI

4/3/2026 at 2:35:14 PM

For me it's just the server. I use openwebui as interface. I don't want it all running on the same machine.

by wolvoleo

4/3/2026 at 12:28:15 PM

Which harness (IDE) works with this if any? Can I use it for local coding right now?

by aetherspawn

4/3/2026 at 12:48:06 PM

Yes, you can use it for local coding. Most harnesses can be pointed at a local endpoint which provides an OpenAI compatible API, though I've had some trouble using recent versions of Codex with llama.cpp due to an API incompatibility (Codex uses the newer "responses" API, but in a way that llama.cpp hasn't fully supported).

I personally prefer Pi as I like the fact that it's minimalist and extensible. But some people just use Claude Code, some OpenCode, there are a ton of options out there and most of them can be used with local models.

by lambda

4/3/2026 at 3:30:10 PM

It needs to support tool calling and many of the quantized ggufs don't so you have to check.

I've got a workaround for that called petsitter where it sits as a proxy between the harness and inference engine and emulates additional capabilities through clever prompt engineering and various algorithms.

They're abstractly called "tricks" and you can stack them as you please.

https://github.com/day50-dev/Petsitter

You can run the quantized model on ollama, put petsitter in front of it, put the agent harness in front of that and you're good to go

If you have trouble, file bugs. Please!

Thank you

edit: just checked, the ollama version supports everything

    $ llcat -u http://localhost:11434 -m gemma4:latest --info
    ["completion", "vision", "audio", "tools", "thinking"]
so you can just use that.

by kristopolous

4/3/2026 at 11:38:18 AM

Last night I had to install the VO.20 pre-release of ollama to use this model. So I'm wondering if these instructions are accurate.

by boutell

4/3/2026 at 10:25:23 AM

There is virtually no reason to use Ollama over LM Studio or the myriad of other alternatives.

Ollama is slower and they started out as a shameless llama.cpp ripoff without giving credit and now they “ported” it to Go which means they’re just vibe code translating llama.cpp, bugs included.

by redrove

4/3/2026 at 10:58:05 AM

I really like LM Studio when I can use it under Windows but for people like me with Intel Macs + AMD gpu ollama is the only option because it can leverage the gpu using MoltenVK aka Vulkan, unofficially. We're still testing it, hoping to get the Vulkan support in the main branch soon. It works perfectly for single GPUs but some edge cases when using multiple GPUs are unsupported until upstream support from MoltenVK comes through. But yeah, I agree, it wasn't cool to repackage Georgi's work like that.

by alifeinbinary

4/3/2026 at 1:40:54 PM

>Ollama is slower

I've benchmarked this on an actual Mac Mini M4 with 24 GB of RAM, and averaged 24.4 t/s on Ollama and 19.45 t/s on LM Studio for the same ~10 GB model (gemma4:e4b), a difference which was repeated across three runs and with both models warmed up beforehand. Unless there is an error in my methodology, which is easy to repeat[1], it means Ollama is a full 25% faster. That's an enormous difference. Try it for yourself before making such claims.

[1] script at: https://pastebin.com/EwcRqLUm but it warms up both and keeps them in memory, so you'll want to close almost all other applications first. Install both ollama and LM Studio and download the models, change the path to where you installed the model. Interestingly I had to go through 3 different AI's to write this script: ChatGPT (on which I'm a Pro subscriber) thought about doing so then returned nothing (shenanigans since I was benchmarking a competitor?), I had run out of my weekly session limit on Pro Max 20x credits on Claude (wonder why I need a local coding agent!) and then Google rose to the challenge and wrote the benchmark for me. I didn't try writing a benchmark like this locally, I'll try that next and report back.

It depends on the hardware, backend and options. I've recently tried running some local AIs (Qwen3.5 9B for the numbers here) on an older AMD 8GB VRAM GPU (so vulkan) and found that:

llama.cpp is about 10% faster than LM studio with the same options.

LM studio is 3x faster than ollama with the same options (~13t/s vs ~38t/s), but messes up tool calls.

Ollama ended up slowest on the 9B, Queen3.5 35B and some random other 8B model.

Note that this isn't some rigorous study or performance benchmarking. I just found ollama unnaceptably slow and wanted to try out the other options.

LM Studio is closed source.

And didn't Ollama independently ship a vision pipeline for some multimodal models months before llama.cpp supported it?

by gen6acd60af

4/3/2026 at 2:20:53 PM

Yes, they introduced that Golang rewrite precisely to support the visual pipeline and other things that weren't in llama.cpp at the time. But then llama.cpp usually catches up and Ollama is just left stranded with something that's not fully competitive. Right now it seems to have messed up mmap support which stops it from properly streaming model weights from storage when doing inference on CPU with limited RAM, even as faster PCIe 5.0 SSDs are finally making this more practical.

The project is just a bit underwhelming overall, it would be way better if they just focused on polishing good UX and fine-tuning, starting from a reasonably up-to-date version of what llama.cpp provides already.

Hmm, the fact that Ollama is open-source, can run in Docker, etc.?

by iLoveOncall

4/3/2026 at 1:02:27 PM

Ollama is quasi-open source.

In some places in the source code they claim sole ownership of the code, when it is highly derivative of that in llama.cpp (having started its life as a llama.cpp frontend). They keep it the same license, however, MIT.

There is no reason to use Ollama as an alternative to llama.cpp, just use the real thing instead.

by DiabloD3

4/3/2026 at 1:32:22 PM

If it’s MIT code derived from MIT code, in what way is its openness ”quasi”? Issues of attribution and crediting diminish the karma of the derived project, but I don’t see how it diminishes the level of openness.

by simondotau

4/4/2026 at 12:43:34 AM

FOSS licensing can only exist in terms of Copyright. Without Copyright, you cannot license FOSS. If something has an incorrect Copyright attribution, then the license can be viewed as invalid until this deficiency has been corrected (obv. depending on local laws, etc).

On top of this, it would not be unreasonable for the numerous authors of llama.cpp to issue DMCA takedown requests if Ollama is unwilling to correct it.

by DiabloD3

4/3/2026 at 2:57:39 PM

Do y'all mean backend or the Ollama frontend or both? I find it trivially easy to sub in my local Ollama api thing in virtually all of the interesting frontend things. I'm quite curious about the "why not Ollama" here.

Does LM Studio have an equivalent to the ollama launch command? i.e. `ollama launch claude --model qwen3.5:35b-a3b-coding-nvfp4`

by faitswulff

4/3/2026 at 12:49:45 PM

I don't think it does, but llama.cpp does, and can load models off HuggingFace directly (so, not limited to ollama's unofficial model mirror like ollama is).

There is no reason to ever use ollama.

by DiabloD3

4/3/2026 at 1:04:00 PM

> I don't think it does, but llama.cpp does

I just checked their docs and can't see anything like it.

Did you mistake the command to just download and load the model?

by ffsm8

4/4/2026 at 12:38:23 AM

As a sibling comment answered you, it is `-hf`.

And yes, it downloads the model, caches it, and then serves future loads of that model out of the cache if the file hasn't changed in the hf repo.

by DiabloD3

4/4/2026 at 12:55:55 AM

So I'm summary: no, it does not have an equivalent command either.

Actually that shouldn't be a question, you clearly did.

LM Studio can absolutely run as as server.

Nice setup. Running models locally on Mac hardware has gotten surprisingly viable. I'm using a similar stack in Switzerland for testing AI agent workflows — the M-series chips handle inference well for tool-calling tasks.

4/3/2026 at 7:12:14 PM

In case anyone’s wondering, I tried it again and it worked this time, even without logging in. Maybe because this was my first visit to GitHub in a new country (I’m currently on vacation), I triggered some sort of anti-scraping measure or something.

Kinda crazy that I can run a 26B model on a 1500€ laptop (MacBook Air M5 32GB). Does anyone know how I can actually use this in a productive way?

by kilzimir

4/3/2026 at 2:41:28 PM

Just told Claude to sort it out and it ran it. 26 tok/s on the Mac mini I use for personal claw type program. Unusable for local agent but it’s okay.

by renewiltord

4/3/2026 at 2:47:04 PM

Isn't 26 tok/s quite usable for a claw-like agent though? You can chat with it on a IM platform and get notified as soon as it replies, you're not dependent on real-time quick interaction.

by zozbot234

4/4/2026 at 2:04:06 AM

For me it's too slow. Prefer using cloud agent. Can do more tasks.

by renewiltord

4/3/2026 at 10:57:08 AM

Why are you using Ollama? Just use llama.cpp

brew install llama.cpp

use the inbuilt CLI, Server or Chat interface. + Hook it up to any other app

By desk you mean that "Mac mini"? Because it is pricey. In my country it is 1000 USD (from Apple for basic M4 with 24GB). My desk was 1/5th of that price.

And considering that this Mac mini won't be doing anything else is there a reason why not just buy subscription from Claude, OpenAI, Google, etc.?

Are those open models more performant compared to Sonnet 4.5/4.6? Or have at least bigger context?

by krzyk

4/3/2026 at 12:39:30 PM

Right now, open models that run on hardware that costs under $5000 can get up to around the performance of Sonnet 3.7. Maybe a bit better on certain tasks if you fine tune them for that specific task or distill some reasoning ability from Opus, but if you look at a broad range of benchmarks, that's about where they land in performance.

You can get open models that are competitive with Sonnet 4.6 on benchmarks (though some people say that they focus a bit too heavily on benchmarks, so maybe slightly weaker on real-world tasks than the benchmarks indicate), but you need >500 GiB of VRAM to run even pretty aggressive quantizations (4 bits or less), and to run them at any reasonable speed they need to be on multi-GPU setups rather than the now discontinued Mac Studio 512 GiB.

The big advantage is that you have full control, and you're not paying a $200/month subscription and still being throttled on tokens, you are guaranteed that your data is not being used to train models, and you're not financially supporting an industry that many people find questionable. Also, if you want to, you can use "abliterated" versions which strip away the censoring that labs do to cause their models to refuse to answer certain questions, or you can use fine-tunes that adapt it for various other purposes, like improving certain coding abilities, making it better for roleplay, etc.

by lambda

4/3/2026 at 2:37:22 PM

You don't need that much VRAM to run the very largest models, these are MoE models where only a small fraction is being computed with at any given time. If you plan to run with multiple GPUs and have enough PCIe lanes (such as with a proper HEDT platform) CPU-GPU transfers start to become a bit less painful. More importantly, streaming weights from disk becomes feasible, which lets you save on expensive RAM. The big labs only avoid this because it costs power at scale compared to keeping weights in DRAM, but that aside it's quite sound.

by zozbot234

4/3/2026 at 4:44:05 PM

While you can run with weights in RAM or even disk, it gets a lot slower; even though on any given token a fraction of the weights are used, that can change with each token, so there is a lot of traffic to transfer weights to the GPU, which is a lot slower than if it's directly in GPU RAM. And even more slower if you stream from disk. Possible, yes, and maybe OK for some purposes, but you might find it painfully slow.

by lambda

4/3/2026 at 1:17:31 PM

I have the same setup (M4 Pro, 24GB). The e4b model is surprisingly snappy for quick tasks. The full 26B is usable but not great — loading time alone is enough to break your flow.

Re: subscriptions vs local — I use both. Cloud for the heavy stuff, local for when I'm iterating fast and don't want to deal with rate limits or network hiccups.

The article has a few good tips for using Ollama. Perhaps it should note that the Gemma 4 models are not really trained for strong performance with coding agents like OpenCode, Claude Code, pi, etc. The Gemma 4 models are excellent for applications requiring tool use, data extraction to JSON, etc. I asked Gemini Pro about this earlier and Gemini Pro recommended qwen 3.5 models specifically for coding, and backed that up with interesting material on training. This makes sense, and is something that I do: use strong models to build effective applications using small efficient models.

> I asked Gemini Pro about this earlier and Gemini Pro recommended qwen 3.5 models specifically for coding, and backed that up with interesting material on training.

The Gemma models were literally released yesterday. You can’t ask LLMs for advice on these topics and get accurate information.

Please don’t repeat LLM-sourced answers as canonical information

by Aurornis

4/3/2026 at 2:40:18 PM

It's not just LLM sourced though, folks have literally tried this after the release with the 26A4B model and it wasn't very good. Maybe the dense ~31B model is worthwhile though.

by zozbot234

4/3/2026 at 2:46:41 PM

Many Gemma implementations are or were broken on launch day. The first attempts to fix llama.cpp’s tokenizer were merged hours ago.

Everyone hated Qwen3.5 at launch too because so many implementations were broken and couldn’t do tool calling.

You need to ignore social media “I tried this and it sucks” echo chambers for new model releases.

by Aurornis

4/3/2026 at 3:34:29 PM

I agree with your criticism. I should have simply said that I had good results with gemma 4 tool use, and agentic coding with gemma 4 didn’t yet work well for me.

by mark_l_watson

4/3/2026 at 2:48:54 PM

I spent two hours doing my own research before asking for Gemini’s analysis, which reinforced my own opinion that the gemini models historically have not been trained and target for agentic coding use.

Have you tried using the new Gemma 4 models with agentic coding tools?If you do, you might end up agreeing with me.

by mark_l_watson

4/3/2026 at 3:08:11 PM

I've found my research on certain topics like this becoming less reliable these days, compared to just trying it out to form an opinion.

by SparkyMcUnicorn

4/3/2026 at 3:21:54 PM

I wasn’t very clear, sorry. By my ‘own research’ I meant spending 90 minutes experimenting with Gemma 4 models for tool use (good results!) and a half hour using with pi and OpenCode (I didn’t get good results, yet.)
