Kinda funny that their "cost-vs-performance" chart looks the same as the one for Composer 2.5[1], except that it includes Composer 2.5 at a completely different spot.

What are the chances that CursorBench ranks Cursor's model highest, and Cognition's bench ranks Cognition's model highest? Both are to be RL'd from Kimi as a base model, BTW.

I'd posit that it's not deliberate deception, but for both companies their training data and benchmarks come from the same dataset (Devin/Cursor interaction logs) so they naturally overfit.

I think it's also telling that they left out the usual hallmarks of the Pareto distribution: GLM 5.2, Qwen 3.7, Minimax M3, and Mimo 2.5

> they left out ... GLM 5.2

They did not.

Okay, let's give software engineers a break for a bit and focus on obsoleting other high-linguistic context occupations.

We need more models that optimize for coding and that can be cheaper than frontier models, like what SWE 1.7 and composer 2.5 are trying to do. I don't think there's an effort to make something GLM-5.2 level but focused only on coding.

Qwen was doing something like this with their coder models. But alas, they seem not to be releasing those anymore. Last one was Qwen3-coder-next.
yousif_123123 [3 hidden]5 mins ago
Its crazy that OpenAI and Anthropic themselves aren't doing that. No attempts at reducing inference cost for code as far as I know from them.
gsibble [3 hidden]5 mins ago
I use this model. It's pretty good but not Opus 4.8 or Fable levels obviously. I'm really hoping we get more models like it (and better) soon. I run it locally and it's great that way.
UncleOxidant [3 hidden]5 mins ago
Qwen3-coder-next is very usable. But I don't think it's as good as Qwen3.6-27B (though it does run faster on my hardware). It would be great if we could get a Qwen3.7-coder, but I'm not going to hold my breath.
petesergeant [3 hidden]5 mins ago
I think showing the API prices for competitors that people don't really pay for that way is all that useful. I do like that it's provisioned by Cerebras though. I think I'd have leant towards focusing on the TPS.

Not finding anything about this while searching huggingface: https://huggingface.co/search/full-text?q=SWE-1.7 i assume this is another closed source model?

Open weight models should have GPL-like license where it says if you train model on it, it needs to be open weight as well.

A company whose first demo was completely fraudulent announces that its model beats GPT-5.5, on its own benchmark? I’m gonna wait a little before I trust this.

This whole company seems to optimize for raising money and impressing VCs. Lying about their products, ignoring consumer market to target enterprise, bragging about how they work their employees like slaves, and writing these posts full of intimidating technical jargon...

achandra03 [3 hidden]5 mins ago
To be fair it does seem like most AI startups are now like this (particularly when it comes to constantly mentioning how hard they work and ignoring consumer markets).
parineum [3 hidden]5 mins ago
> it does seem like most AI startups are now like this

Remember when AGI was going to replace all jobs in 6 months? It's always been like that.

SubiculumCode [3 hidden]5 mins ago
Link for this?
andy99 [3 hidden]5 mins ago
Is it just me or does all that* seem pretty tame by today’s standards? Not saying it’s right, but it barely raises eyebrows. Sounds like a pretty typical startup demo.

* Based on the first comment in the link that claims to summarize the video.

> "A company whose first demo was completely fraudulent"

Could you expand on this?

giancarlostoro [3 hidden]5 mins ago
Would love to see these companies use benchmarks done by third parties.
anthonypasq [3 hidden]5 mins ago
they are right there? it shows swe-bench multilingual and terminal bench
w4yai [3 hidden]5 mins ago
What happened ?
haritha1313 [3 hidden]5 mins ago
Their product has far evolved beyond this (of course with the large amount of money being poured into it) and is now used by a lot of traditional companies (banks etc). Also the SWE models were originally built by Windsurf and this seems to be on top of that (after acquisition) although the original SWE-1 models weren't that groundbreaking.
spate141 [3 hidden]5 mins ago
Feels like they discovers that if you build your own benchmark, you can win it
londons_explore [3 hidden]5 mins ago
Pretty sure most benchmarks are being gamed by people training on the test set deliberately or accidentally anyway.

Unrelated: what's the point of "*equal contribution"? Why would someone specify this
edot [3 hidden]5 mins ago
Because papers are often referred to by the first author’s name, and often the first author is the primary researcher and therefore deserves the extra credit. When two or more primary authors are equally involved, they’ll often do a random ordering but annotate this so that no one thinks one did more than the others.
nibbleyou [3 hidden]5 mins ago
Interesting. Thank you
throwaw12 [3 hidden]5 mins ago
Open source for the win!

Imagine how far community might have pushed if 2 past versions of 'morally superior' Anthropic and 'completely Open AI' open sourced their models for the community to build on top of them

spott [3 hidden]5 mins ago
Is this open source? I can't find a link to download the weights.
UncleOxidant [3 hidden]5 mins ago
It's based on an open weight model (Kimi 2.7) so shouldn't it also be open weight?
NitpickLawyer [3 hidden]5 mins ago
> so shouldn't it also be open weight?

Should as in "would it be nice?" - yeah. Should as in they have to? No.

andy99 [3 hidden]5 mins ago
There is no obligation to do that. I think the landscape would be very different now if one of the big labs had released an earlier “frontier” model under copyleft that requires sharing fine tunes. I hope it still happens.
fallinditch [3 hidden]5 mins ago
I'm looking forward to trying this out. I've been using SWE 1.6 quite a lot for grunt work alongside Opus for higher level planning and tricky stuff - a good combo.

As a (former) Windsurf user I'm pretty happy with the progress of the Cognition/Devin ecosystem after they took over Windsurf, now known as Devin Desktop.

hedgehog [3 hidden]5 mins ago
Heads up to anyone else curious, I installed the Devin CLI and SWE-1.7 is not currently available there.
achierius [3 hidden]5 mins ago
I've always had mixed feelings about Cognition. Obviously they have some very, very smart people working there (I even know a few), and they do make real products. But at the same time, they've made suspicious marketing claims more than once and even been caught making outright fabricated ones; and while they certainly seem to have shaped up from that, I still find their claims to be in a sort of grey area where they seem to avoid unfavorable comparisons and lean on their own benchmarks. Certainly when I've tried their models they have not been nearly as useful as comparable versions of Claude, GLM, etc. -- though I haven't had a chance to try SWE-1.7 yet.
llmslave [3 hidden]5 mins ago
These models are never as good, the benchmarks dont tell the full story
haritha1313 [3 hidden]5 mins ago
The reality is most people building their own models and providing that alongside SOTA ones don't really care about how great these models are. They just prove that 'hey we are smart enough to build our own models so you can trust us instead of going with a single provider like Claude via Claude Code', also a cheap alternative for cost sensitive/free users - at least this was the case for Windsurf, not sure if Devin Desktop still has that tier. They just need to hillclimb the benchmarks and show something reasonable enough there.
SubiculumCode [3 hidden]5 mins ago
Funny, the cheerleading at HN for leading Chinese models, but a non Chinese lab (building on top of a Chinese model) gets dissed here.
mirekrusin [3 hidden]5 mins ago
It's simple: close weights = not welcome.
sosodev [3 hidden]5 mins ago
It's almost as if HN users aren't all the same.
llmslave [3 hidden]5 mins ago
all the open source models are a waste of time relative to the bleeding edge from openai/anthropic
wongarsu [3 hidden]5 mins ago
At work I wouldn't want to use anything else. Compared to my salary a Claude subscription (or two) is cheap

For hobby projects I've completely switched to DeepSeek v4 pro. I spend less than on a $10 Claude plan and am not subjected to quota limits (when I have time and motivation, the last thing I want is a 5 hour quota running out). And the difference in model performance is fine for those smaller projects, most of which will end up abandoned or in a state of "good enough" anyways

And for utility tasks, those 30b models are also great. I'm a big fan of gemma4

llmslave [3 hidden]5 mins ago
ive just got better things to do with my life than fuss with an inferior model. its like why hire a dumb employee over a smart one
pixel_popping [3 hidden]5 mins ago
Not true since a few months, genuinely try GLM 5.2 and Minimax M3, especially in adversarial/gating... as a general model, I can agree, but as a coding model, they are not bad, comparable to maybe Opus 4.5 in real usage which is quite impressive.
villish [3 hidden]5 mins ago
I use GLM or DS4 to help me draft a better initial prompt with more information that I then give to Sonnet 5/Fable/GPT5.5. While benchmarks show the open models close to frontier level, my experience with them is drastically different. I have high confidence that Fable or GPT will 1 shot solutions.

At least with low level programming languages. They're all very good for webdev stuff.

llmslave [3 hidden]5 mins ago
yeah but why waste your time on these models, just use the one that gets the better results
nicoburns [3 hidden]5 mins ago
I actively prefer GLM-5.2 for some tasks. For simple tasks the results are just as good as e.g. Opus, and it produces results significantly faster.
9183726518 [3 hidden]5 mins ago
Because you can get them from more trustworthy providers or with hardware encryption.
llmslave [3 hidden]5 mins ago
i trust anthropic/openai with my data far more than some random startup.
somenameforme [3 hidden]5 mins ago
I was going to respond until I saw your account name lol.
spate141 [3 hidden]5 mins ago
Benchmarks are just vibes with error bars... wake me up when it survives a week on a real codebase without hallucinating a package that doesn't exist.
