Show HN: Needle: We Distilled Gemini Tool Calling into a 26M Model

 https://github.com/cactus-compute/needle

by HenryNdubuaku

5/13/2026 at 12:21:15 AM

Do you have any examples or data on the discriminatory power of the model for tool use?

The examples are things like "What is the weather in San Francisco", where you are only passed a tool like

  tools='[{"name":"get_weather","parameters":{"location":"string"}}]',
I had a thing[1] over 10 years ago that could handle this kind of problem using SPARQL and knowledge graphs.

My question is how effective is it at handling ambiguity.

Can I send it something like a text message "lets catch up at coffee tomorrow 10:00" and a command like "save this" and have it choose a "add appointment" action from hundreds (or even tens) of possible tools?

Thanks to a Huggingface linked below, I tested it and im not impressed. prmopt: i need to contact my boss i will be late. Result: 20mins [{"name":"set_timer","arguments":{"time_human":"20 minutes"}}]. It didnt use the email tool and i tried 2-3 different ways of asking it.

by michelsedgh

5/13/2026 at 9:32:58 AM

Query: context: { "boss_email": "bigboss69420@corporatepersonhood.net", "upcoming_meetings": [{ with: "bigboss69420@corporatepersonhood.net", "time": "11:00" }] } user: i need to contact my boss i will be late, could you tell him I'll be 15 minutes late?

Output: [{"name":"send_email","arguments":{"to":"bigboss69420@corporatepersonhood.net","subject":"upcoming_meetings","body":"I'll be 15 minutes late"}},{"name":"send_email","arguments":{"to":"bigboss69420@corporatepersonhood.net","subject":"time","body":"I'll be 15 minutes late"}},{"name":"send_email","arguments":{"to":"bigboss69420@corporatepersonhood.net","subject":"time","body":"I'll be 15 minutes late"}}]

Context definitely helps. But yeah the quality of it doesn't seem to be too high. To be fair it makes you realise that not only is parameter extraction required, but also content generation (email body). Also debouncing the 3 tool calls.

Maybe under very specific circumstances/very tight harness this sort of model would be useful?

by fennecfoxy

5/13/2026 at 3:08:19 AM

works for me:

input: i need to contact my boss i will be late. output: [{"name":"send_email","arguments":{"to":"boss@company.com","subject":"Running late","body":"I will be late for the meeting."}}]

it did have the send_email tool on the left hand side though

by mahmoudimus

5/13/2026 at 7:18:52 AM

Boss: what meeting are you talking about..?

In the ideal scenario, the boss also uses Needle, which checks emails and schedule a late meeting with whoever sent that email.

Needle on the other side receives the invite for a late meeting, and notify OP he's got a 67% chance of getting fired today.

Hmm.. this might make it feasible to build something like a command line program where you can optionally just specify the arguments in natural language. Although I know people will object to including an extra 14 MB and the computation for "parsing" and it could be pretty bad if everyone started doing that.

But it's really interesting to me that that may be possible now. You can include a fine-tuned model that understands how to use your program.

E.g. `> toolcli what can you do` runs `toolcli --help summary`, `toolcli add tom to teamfutz group` = `toolcli --gadd teamfutz tom`

by ilaksh

So Needle is trained for INT4, what you see in the playground is INT4, only 14MB, same challenge though.

Oh gotcha. Fixed my comment.

Are you worried about Google's response to this? Google reportedly reacts to distillation attempts "with real-time proactive defenses that can degrade student model performance". So if they detected you, they could have intentionally fed you a dumber but plausible variant of Gemini: https://cloud.google.com/blog/topics/threat-intelligence/dis...

But also, this model is small and just focusing on the tool use. In terms of token usage, you're probably not anywhere near the people that are trying to distill the entire model.

It is more like imitating the imitators. There is not much of a legal case here, but poisoning the data is fair game both for those producing original data as well as for those producing its regurgitations.

I know we all think of bad things when we hear "short form video" but short demos can do a LOT for any project, shows the user how its used, what it looks like, what it solves, etc all in anywhere from 15 seconds to a couple of minutes, doesn't need to be ultra fancy, screen recording is fine. :)

by giancarlostoro

5/12/2026 at 9:16:29 PM

Since there is no GUI here, I feel like a simple plaintext chat transcript would be both 100x smaller and 100x easier to read. (Not to mention accessible.)

Sure, and we've seen those terminal screen recorders that give you back a replayable demo, that could work too.

>Experiments at Cactus showed that MLPs can be completely dropped from transformer networks, as long as the model relies on external knowledge source.

Heh, what a coincidence, just today one of my students presented research results which also confirmed this. He removed MLP from Qwen and the model still could do transformation tasks on input but lost knowledge.

The "M" nomenclature has been around since at least BERT and T5/FLAN. It's valid to use it even if today's LLM devs are more familiar with billion-scale models.

by bigyabai

25-35 Billion is expected these days, there's many models of this size, it's very common. (Gemma 4 31B, Qwen 3.6 25B & 35B, JT 35B, EXAONE 35B, Nemotron 30B, GLM 4.7-flash 30B, Servam 30B, LFM2 24B, Granite 4.1 30B...)

by f33d5173

5/13/2026 at 4:49:30 AM

This is neat, and matches an observation I saw with early Claude Code usage:

Sonnet would often call tools quickly to gather more context, whereas Opus would spend more time reasoning and trying to solve a problem with the context it had.

This led to lots of duplicated functions and slower development, though the new models (GPT-5.5 and Opus 4.6) seem to suffer from this less.

My takeaway was that “dumber” (i.e. smaller) models might be better as an agentic harness, or at least feasibly cheaper/faster to run for a large swath of problems.

I haven’t found Gemini to be particularly good at long horizon tool calling though. It might be interesting to distill traces from real Codex or Claude code sessions, where there’s long chains of tool calls between each user query.

Personally, I’d love a slightly larger model that runs easily on an e.g. 32GB M2 MBP, but with tool calling RL as the primary focus.

Some of the open weight models are getting close (Kimi, Qwen), but the quantization required to fit them on smaller machines seems to drop performance substantially.

by jumploops

5/13/2026 at 5:19:58 AM

The key is to not run LLMs in loops. This trend of agentic frameworks is silly, and mostly exists to make LLM companies more revenue. An LLM is mostly useless but is much more useful and reliable with one shot tooling.

I have a suite or tools ive built for myself on top of the openrouter api for very specific tasks. Press button amd LLM does (one) useful thing, not press button and let LLM run tool calls in a loop for 5 minutes and hope it does things in the correct order.

If multiple tools need to be called to do a useful thing, I will chain those together deterministically in my code. This is much more reliable as I can check the output of A before proceeding to task B or C, also its more time and token efficient. Agentic loops are a huge scam.

by ai_fry_ur_brain

5/13/2026 at 10:28:34 AM

Often I find LLMs doing multiple steps to achieve some goals (e.g. do certain operations against JIRA or Gitlab), and if the LLM work seems useful, I instruct it to create a tool to achieve the task more directly and revise skill data to make use of the tool.

Granted I've let it mostly vibecode those tools, so they might be garbage. I should perhaps have it do a refactoring round to make more composable tools..

by _flux

5/13/2026 at 5:50:08 AM

You are completely wrong, but one might get that impression from not using SOTA models in the Sonnet ballpark.

by incrudible

5/13/2026 at 7:16:13 AM

I think both preceding comments are a bit too strongly worded. I’m experimenting as well with pairing deterministic programming with llm use in a similar fashion and find that it allows you to squeeze more out of smaller models than with llm-only agentic loops. It is also no question for me that the large SOTA models can do way more in llm-only agentic loops with less hassle and pre-work. If you discount the hassle of actually running them, that is. So I guess it depends a bit on what your objective is.

For the love of all that's holy, folks please stop investing your time to fill in the gaps that the Slop Corporations are leaving wide open in their "tooling". Why should you strain yourself in an attempt to "make it work" one way or another? Google, MS, Meta, OpenAI etc. are all now subtly pushing to call their tooling "Intelligence" (not even Artificial Intelligence), so why is it not intelligent? Why does it not work? 1T+ investments and still we should think of best magic chants and configurations to make the slop generators produce half-valid output? All while some of the tech leaders are openly threatening to subdue us in their weird visions of "civilisation" ? We have a better use for our superior brains, let's not denigrate ourselves into being helpless helpers to the magic oracle (if at least it was some magic oracle!)

Lovely to see the push for tiny models.

I have been building for small (20B or less) models for quite a while. Highly focused/constrained agents, many of them running together in some kind of task orchestration mode to achieve what feels like one "agent".

I build (privacy first) desktop apps this way and I want to get into mobile apps with similar ideas but tiny models.

Gemma4 edge models were promised to be great for agentic use, but have been really disappointing in all my tests. They fail at the most basic tool use scenarios.

Have you run any tool-use benchmarks for Needle, or do you plan to? Would be great if you could add results to the repo if so.

Dumb questions, from someone not in the field...

What is a distilled model?

Why doesn't Google do this (to make their models smaller)?

Seems like you could make a competitor to Gemini?

by exabrial

5/13/2026 at 5:38:59 AM

There are two answers already and neither is entirely adequate.

In normal LLM training, you take a set of documents and have it learn to predict the future, then have some private RLHF/RLVR etc. data that it learns to produce good chat outputs from.

In distillation, you take a set of prompts you are interested in, and record the big LLM's outputs, then train your small model to produce the same output as the big LLM.

This has a few advantages - you can get performance much more quickly on your documents/prompts of interest, with a much cheaper training budget, and you don't have to worry about acquiring very expensive RLHF/RLVR training data.

A lot of the very good Chinese LLMs got very good very quickly through distillation from frontier models, which is why Anthropic/Google/OpenAI are blocking it so aggressively.

by jmalicki

5/13/2026 at 6:15:13 AM

For completeness sake I'll add a bit more.

The concept of distillation is not new in ML, and there are nuances to it. Traditionally you would have access to the bigger model, and for LLMs specifically you can train the small model on the entire distribution of output logits at the same time. So this would train the small model to output scores for each token in a similar fashion to the large model. There's "more to learn" from the entire distribution, rather than just from the chosen token.

But since you don't have access to this from the API providers, the next best thing is to use the outputs themselves and train on those. That's more like a "poor man's distillation". It's still good, and as you mentioned worked fairly well for models catching up. But a lab that develops both the big model and the small model could make it better. (or you could choose to distill from an existing open model).

by NitpickLawyer

5/12/2026 at 10:43:58 PM

No question is stupid!

1. Distilled means taking the intelligence of a big model and compacting into a tiny model.

2. Google already does so with FunctionGemma, but Needle argues that better performance could be achieved with 10x smaller model using our technologies.

by HenryNdubuaku

5/12/2026 at 10:53:16 PM

Model distillation is lossy compression of big model to produce a smaller model.

Smaller model requires less space on disk, less video memory, and less compute (cheaper hardware).

Downside is that distilled model performs worse on the same benchmarks compared to original model.

by tintor

5/13/2026 at 9:11:16 AM

How could you use this for composability? I.e. chaining together multiple tools. For example web_search → summarize_url → send_email

Looks possible E.g.

This is pretty much exactly what I want for Home Assistant. I yell out, "Computer! Lights!" and it toggles the lamp in the room on or off. (I mean I can do that now, I think, but probably with a much larger model.)

I haven't played with it yet, but does it ever return anything other than a tool call? What are the failure modes? What if it doesn't understand the request? Does it ever say it can't find a tool? Does it get confused if there are two similar (but different) tools? Can it chain tools together (e.g. one tool to look up and address and another to get directions to the address)?

I mean, I plan on downloading the model later tonight and finding out for myself, but since I'm stuck at work right now, I figured I'd ask anyway...

A local model that can do better than Siri or Alexa as a personal or home assistant is, in my eyes, very useful. Being able to run on a phone or watch or glasses translates to me, low-powered AI, and not necessarily that I want my phone, or watch, or glasses to run things for me.

My Siri use has narrowed down to just setting timers. And even then, I still have my phone call people in the middle of the night. Siri is pretty dumb and does not do what I want it. I’d rather be able to customize an assistant to myself.

I am also thinking of automation in my day to day workflow for work.

by hosh

5/13/2026 at 4:18:37 AM

Throwing a few things out - HN has changed over the years, but people make stuff to make stuff. There don't need to be product use cases. The tone of the comment goes against the spirit of HN - likely the reason for downvotes.

That aside- a very small model that takes text and outputs structured json according to a spec is nice. It let's you turn natural language into a user action. For example, command palettes could benefit from this.

If you can do a tiny bit of planning (todo) and chain actions, it seems reasonable that you could traverse a rich state space to achieve some goal on behalf of a user.

Games could use something like it for free form dialog while stool enforcing predefined narrative graphs etc.

I'm sure you could come up with more. It's a fuzzy function.

OK. Great! So it doesn't need to be a commercial product. But does it do something (anything?) interesting? I'm interested in your games example, I'd love to see it done in real life. IIUC, game AIs are actually much more constrained and predictable for play-ability reasons. If you let it go all free form a plurality of players have a "WTF??!?" experience which is super Not Good.

It doesn't have to do any thing interesting - it's completely fascinating all on it's own. If you understand anything about the math and science behind LLMs, you'll understand that this is an achievement worthy of sharing to a community like HN.

That being said, small models like these have plenty of use cases. They allow for extra "slack" to be introduced into a programmatic workflow in a compute constrained environment. Something like this could help enable the "ever present" phone assistant, without scraping all your personal data and sending it off to Google/OpenAI/etc. Imagine if keywords in a chat would then trigger searches on your local data to bring up relevant notes/emails/documents into a cache, and then this cache directly powers your autocomplete (or just a sidebar that pops up with the most relevant information). Having flexible function calling in that loop is key for fault tolerance and adaptability to new content and contexts.

Its cool. Enjoy it.

OK so show me what that's for. Show me something useful you can do with that ability.

I'm really trying but.. idgi? I truly cannot imagine how this would improve my life in any way...

> Its cool. Enjoy it.

No. It sounds like a useless complication on my watch. I don't fucking care if it can tell me the phase of the moon. I can look up at the sky and see the moon and know what phase it is.

You can think of “phone use” for instance, what Siri is supposed to be.

by HenryNdubuaku

5/12/2026 at 11:16:31 PM

I mean.. Siri basically works? When I'm driving I say "Hey Siri, find me a gas station along my route", and it does. Or I say "Hey Siri, call Joe Bob mobile" and it does. Or I say "Hey Siri, play me a podcast". This is kind of a solved problem already? When I'm driving this is literally as complicated of a distraction as I want--I'm not going to be dictating emails or texts. When I'm not driving, the touchscreen keyboard (as shitty an interface as that is) is 100x better than voiced natural language commands.

by jcgrillo

5/12/2026 at 11:31:42 PM

It does just barely work now after they spent billions, and they may still fall back to cloud LLMs for a significant number of things. This is a way that everyone can get that on the actual Apple Watch or local phone for any application they build.

by ilaksh

5/12/2026 at 11:50:32 PM

I get that, but I still can't imagine what it might be for. TBH I don't have a smart watch, because I can't think of anything I'd want one for--my mechanical watch keeps time to within a few seconds per month and the lume lasts all night. I don't know what making it "smarter" would do for me, it does an A+ job of being a watch. What are the things that "everyone" can build with this that actually matter? Like, what is the differentiator?

EDIT: To be clear, the monoculture of phone operating systems sucks. If this somehow enables more entrants into that space then I'm all for it. However, I don't see this in particular being the deciding factor... For example, the reason I don't run a 3rd party operating system on my phone isn't because it's lacking Siri or "OK Google" (if these things went away tomorrow I'd barely notice), it's because it would be a pain in the ass to make it be a phone.

Is the idea here to add function calling to models that don't have it, or even improve function calling (qwen quirks)?

So it’s a tiny model capable of function calling that could run locally on cheap devices.

No FFN is blowing my mind. This is pretty much "Attention Is ACTUALLY All You Need". Reminds me of BERT Q&A which would return indices into the input context, but even that had a FFN. Really exciting work.

by efskap

5/13/2026 at 1:49:05 AM

I guess this had always been bugging me. I get while you need activation/non-linearities, but do you really need the FFN in Transformers? People say that without it you can't do "knowledge/fact" lookups, but you still have the Value part of the attention, and if your question is "what is the capital of france" the LLM could presumably extract out "paris" from the value vector during attention computation instead of needing the FFN for that. Deleting the FFN is probably way worse in terms of scaling laws or storing information, but is it an actual architectural dead-end (in the way that deleting activation layer clearly would be since it'd collapse everythig to a linear function).

> if your question is "what is the capital of france" the LLM could presumably extract out "paris" from the value vector during attention computation instead of needing the FFN for that.

But how do you get 'Paris' into the value vector in that case? The value vector is just the result of a matrix multiplication, and without a nonlinearity it can't perform a data-dependent transformation. Attention still acts as a nonlinear mixer of previous values, but your new output is still limited to the convex combination of previous values.

by Majromax

5/13/2026 at 4:26:52 AM

> But how do you get 'Paris' into the value vector in that case?

Ok wait I think I see what you mean. Although maybe it's not getting paris _into_ the value vector that's hard, but isolating the residual stream to _only_ that instead of things like other capitals.

So as a naive example maybe at the very first layer consuming your tokens: Q{France} would have high inner product with K{capital} and so our residual would now mostly contain V{capital}, which maybe contains embeddings of all the capitals of all countries. You need some way to filter out all the other stuff, but can't do that without a FFN + activation.

Just throwing in a relu by itself won't help since that would still work on all the elements uniformly, you need some way to put weight on "paris" while suppressing the others, i.e. mixing within the residual stream itself.

Although maybe if you really stretch it, somewhere in a deeper layer you could have 1-hot encoded values with a "gain" coefficient so that when you do the residual addition it's something like {<paris>, <tokyo>, <dc>} + 10000*{<1>, <0>, <0>} and then if you softmax that you get something with most of its mass on "Paris". But it seems like this would not be practical, or it's just shifting the issue to how that the right 1-hot vector is chosen

Query: in 1 hour set a timer for 1 hour

I'd expect either a chain load or just a 2 hour timer. Further attempts humorously give two separate 1-hour-timers.

My own interest / project isn't really in use for games, tbh. Historical background on MOO wasn't really on the gaming side, more social interaction. But similar constraints around community magnetism apply.

Something like this together with MCP can replace APIs for 3rd party integrations. You just give it instructions to "post a message in slack" and provide it slack MCP tools and it figures out the rest on its own. No need to read up on slack API docs or worry about breaking changes.

by varispeed

5/12/2026 at 11:31:01 PM

I don't think the limit is just on tiny devices. It can also be used in apps on generic computers, because its so small anything can run it reasonably quick.

For example, I am thinking this could be helpful for say if you have a complicated build and test infrastructure, fine tune this model on that infrastructure and then people can say more generic things like build and run this library's test, rather than issuing the exact commands to do that or going to Claude, GHCP, etc

by chris_money202

5/12/2026 at 9:35:20 PM

I source old, defective high-end radios with timeless designs from brands like Grundig or Braun, and replace the original hardware with a Raspberry Pi while using the original audio parts to build custom smart speakers. Reliable hotword detection and voice command recognition have been a persistent challenge over the years, but whisper and other small models have helped enormously. At the moment I have ollama running on my server with qwen 9b which works fine but a 26M that could be deployed on the pi itself would be amazing.

FYI, distilling Gemini is explicitly against the ToS:

"You may not use the Services to develop models that compete with the Services (e.g., Gemini API or Google AI Studio). You also may not attempt to reverse engineer, extract or replicate any component of the Services, including the underlying data or models (e.g., parameter weights)."
