MiniMax M2.1: Built for Real-World Complex Tasks, Multi-Language Programming

https://www.minimaxi.com/news/minimax-m21

I've played with this a bit and it's ok. I'd place it somewhere around sonnet 4.5 level, probably below. But with this aggressive pricing you can just run 3 copies to do the same thing, choose the one that succeeded and still come out way ahead with the cost. Not as great as following instructions as Claude models and can get lost, but still "good enough".

I'm very happy with using it to just "do things". When doing in depth debugging or a massive plan is needed, I'd go with something better, but later going through the motions? It works.

Would it kill them to use the words "AI coding agent" somewhere prominent?

"MiniMax M2.1: Significantly Enhanced Multi-Language Programming, Built for Real-World Complex Tasks" could be an IDE, a UI framework, a performance library, or, or...

It's not an AI coding agent. It's an LLM that can be used for whatever you'd like, including powering coding agents.

That reinforces OP’s point that it isn’t clear from their wording. I initially thought it was a speech model, then I saw Python, etc., and it took me a bit more reading to understand what it actually is

by pdyc

12/26/2025 at 5:52:01 AM

HA! I almost added a disclaimer to the original message that I wasn't certain in my identification, hence the request/complaint that they didn't make it clear. But I figured the message would be more effective if I "confidently got it wrong" rather than asking, so I went with it.

its main Chinese competitor GLM is like making 50 cents USD each in the past 6 months from its 40 million "developer users", calling your flagship model "AI coding agent" is like telling investors "we are doing this for fun, not for money".

by tw1984

12/26/2025 at 8:12:43 AM

I think people should stop comparing to sonnet, but to opus instead since it's so far ahead on producing code I would actually want to use (gemini 3 pro tends to be lacking in generalization and wants things to be using it's own style rather than adapting).

Whatever benchmark opus is ahead in should be treated as a very important metric of proper generalization in models.

by kachapopopow

12/26/2025 at 11:08:24 AM

I generally prefer Sonnet as comparison too. Opus, as good as it is, is just too expensive. The "best" model is the one I can use, not the one I can't afford.

These days, by default I just use Sonnet/Haiku. In most cases it's more than good enough for me. It's plenty with $20 plan.

With MiniMax, or GLM-4.7, some people like me are just looking for Sonnet level capability at much cheaper price.

by azuanrb

12/26/2025 at 11:53:26 AM

Are you using GLM-4.7? I've just spent a fortune on Opus, and I heard GLM was close -- but after integrating it into cursor, it seems to spin forever, loose tool use, and generates partial? plans. I did look into using it with the claude cli tool, so it could be cursor specific -- but I havent had the best experience despite going for the pro plan with them. Any advise on how you're using GLM effectively? If at all

At the moment Opus is the only model i can trust even when it generates "refactoring work", it can do the refactoring.

by mjburgess

12/26/2025 at 12:27:05 PM

I’m on the Lite plan. For coding, I still prefer Claude because the models are simply better. I mainly use CLI tools like Claude Code and OpenCode.

I’m also managing a few projects and teams. One way I’m getting value from my GLM subscription is by building a daily GitHub PR summary bot using a GitHub Action. It’s good enough for me to keep up with the team and to monitor higher-risk PRs.

Right now I’m using GLM more as an agent/API rather than as a coding tool. Claude works best for agentic coding for me.

I’m on Claude $20 plan and I usually start with Haiku, then I switch to Sonnet or Opus for harder or longer tasks.

by azuanrb

12/26/2025 at 1:38:39 PM

> I did look into using it with the claude cli tool, so it could be cursor specific

Claude Code with GLM seems ok to me, I just it use it as a backup LLM if in case I hit usage limits but for some light refactoring it did the job well.

Are you also facing issues with Claude Code and GLM?

by sumedh

12/27/2025 at 5:52:05 AM

No matter the price they're far cheaper than a developer and opus / gemini 3 pro are both at a level where they're really useful pair programmers and opus at times can be given a spec to implement and it will do it after 30 minutes with no input from me.

by kachapopopow

12/26/2025 at 11:50:00 AM

are you counting price per token or price per successful task? I'm pretty sure opus 4.5 is cheaper per task than sonnet in some use cases.

by baq

12/26/2025 at 12:51:06 PM

Per successful tasks. The result are mixed. Like you mentioned, it can be cheaper but only in some use cases. I'm only on the $20 plan. If I use Opus and it's not as efficient for my current tasks, I'll burn through my limit pretty fast. Ended up can't use any anymore for the next few hours.

Whereas with Sonnet/Haiku, I'm much more guaranteed to have 100% AI assistance throughout my coding session. This matters more to me right now. Just a tradeoff I'm willing to make.

by azuanrb

12/26/2025 at 12:45:21 PM

Opus is 3x cheaper now.

I think it's still not on the $20 plan tho which is sad.

by andai

12/26/2025 at 12:57:15 PM

Available since few weeks ago.

> Claude Opus 4.5, our frontier coding model, is now available in Claude Code for Pro users. Pro users can select Opus 4.5 using the /model command in their terminal.

Opus 4.5 will consume rate limits faster than Sonnet 4.5. We recommend using Opus for your most complex tasks and using Sonnet for simpler tasks.

by azuanrb

12/26/2025 at 10:18:00 PM

Use Claude Opus in Antigravity. Google is very generous with the limits. The best part is, if you hit your limit, you can switch to Gemini Pro High.

I think Google is able to do this because they host Claude on their own TPUs in their datacentres (probably for Vertex AI customers). So they can undercut just about anyone include Anthropic on costs!

No matter which model you start with, having the other frontier model as a backup is fantastic. Essentially you’re getting 2x the limit.

by sheepscreek

12/26/2025 at 12:52:19 PM

It is now. But the limit on $20 plan is quite low and easy to use up.

> MiniMax has been continuously transforming itself in a more AI-native way. The core driving forces of this process are models, Agent scaffolding, and organization. Throughout the exploration process, we have gained increasingly deeper understanding of these three aspects. Today we are releasing updates to the model component, namely MiniMax M2.1, hoping to help more enterprises and individuals find more AI-native ways of working (and living) sooner.

This compresses to: “We are updating our model, MiniMax, to 2.1. Agent harnesses exist and Agents are getting more capable.”

A good model and agent harness, pointed at the task of writing this post, might suggest less verbosity and complexity— it comes off as fake and hype-chasing to me, even if your model is actually good. I disengage there.

I saw yall give a lightning talk recently and it was similarly hype-y. Perhaps this is a translation or cultural thing.

by jondwillis

12/26/2025 at 2:27:27 AM

so when MiniMax released a pretty capable model, you choose to ignore the model itself and just focus a single sentence they wrote in the release note and started bad mouthing it.

is it a cultural thing?

by tw1984

12/26/2025 at 8:57:03 AM

It’s called bikeshedding and yes it’s a cultural thing on HN. [1]

Most people here are big company worker bees where they take zero risks and do very little of substance.

In these organizations, it’s common for large groups of people to get together in “meetings” and endlessly nitpick surface-level details of unimportant things while completely missing the big picture because it’s far too complex to allow for easy opinions or smart-sounding critique.

a model is not software, it is a bunch of weights.

you are more than welcomed to pick whatever model or software you choose to trust, that is totally fine. However, that is vastly different from bad mouthing a model or software just because its release note contains a single sentence you don't like.

by tomcam

Very anecdotal but for me this model has very weak prompt adherence. I compared it a tiny bit to gemini flash 3.0 and simple things like "don't use markdown tables in output" was very hard to get with m2.1

Took me like 5 prompt iterations until it finally listened.

But it's very good, better than flash 3.0 in terms of code output and reasoning while being cheaper.

by gempir

12/26/2025 at 2:36:01 PM

Has anyone used this in earnest with something like OpenCode? Over the past few months I’ve tested a dozen models that were claimed to be nearly as good Claude Code or Codex, but the overall experience when using them with OpenCode was close to abysmal. Not even a single one was able to do a decent code editing job on a real-world codebase.

by p5v

12/26/2025 at 4:02:56 PM

With M2, yes - I’ve used it in Claude Code (e.g. native tool calling), Roo/Cline (e.g. custom tool parsing), etc. It’s quite good and for some time the best model to self-host. At 4bit it can fit on 2x RTX 6000 Pro (e.g. ~200GB VRAM) with about 400k context at fp8 kv cache. It’s very fast due to low active params, stable at long context, quite capable in any agent harness (its training specialty). M2.1 should be a good bump beyond M2, which was undertrained relative to even much smaller models.

by t1amat

12/26/2025 at 3:40:08 AM

How is everyone monitoring the skill/utility of all these different models? I am overwhelmed by how many they are, and the challenge of monitoring their capability across so many different modalities.

This is the best summary, in my opinion. You can also see the individual scores on the benchmarks they use to compute their overall scores.

It's nice and simple in the overview mode though. Breaks it down into an intelligence ranking, a coding ranking, and an agentic ranking.

One of the demos shows them using Claude Code, which is interesting. And the next sections are titled 'Digital Employee' and 'End-to-End Office Automation'. Their ambitions obviously go beyond coding. A sign of things to come...

anthropic playbook does include the false claim publicly made by its CEO that "in six months AI would be writing 90 percent of code". he made that claim 10 months ago. it is a criminal offence for intentionally misleading investors in many countries.

That they are still training models against Objective-C is all the proof you need that it will outlive Swift.

by monster_truck

Why would they not? Existing objective-c apps will still need updates and various work. Models are still trained on assembler for architectures that don't meaningfully exist today as well.
