Great! Finally follows custom tool call format (k2.6 couldn't). It's a good indicator of instructions following and agentic behaviour. UIs it's generating is pretty good, not without problems, but certainly better than other models at this price point.

What do you mean by custom format? Non-json?

Cursor's composer models are finetuned kimi

They are unusable (unless you want to deliberately destroy your codebase). So if Cursor's models are Kimi based, then well. I'll skip them altogether.

Composer 1.x was poor. The new one is a totally different beast and absolutely fine for day to day.

I've heard this claim before but I've never seen any evidence.

Have you looked, or you’re just waiting for someone to hand it to you?

The burden of evidence is on the accuser.

I only use composer 2.5 day to day and it works fine with human review.

> China is a communist country with elements of capitalistic markets baked in. While I get the point you're making (it should be pretty obvious to anyone who's held a newspaper), I think it's important regardless to point out that Chinese companies AFAIK aren't worker-owned or -controlled, so you can't exactly call it communism, either. And they obviously do not have a "free market capitalism", as you just discussed.…

The companies are all worker owned, because the state exists for the people, and the state owns everything. At least on paper that's how it is sold. After all it is the Peoples Republic of China.

I mean, if that's the bar then the state owns everything in America as well. After all, you don't really own your land if the state can regulate what you do on it, what it can be used for, what you can build on it, and can take it away if they really need it. The state owns the land, the money supply, and regularly restricts and instructs businesses to take or desist from actions.

As such, the state owns everything in both countries, the only differences are to what extent they control things.

I wouldn't even call the USA a capitalist system anymore, the economy is so heavily regulated and interfered with. It's a "managed economy", like pretty much every other nation's economy in the present day.

I think any new model not demonstrably maybe 20-30% over Deepseek v4 capabilities priced over the price per token of Deepseek is almost automatically deprecated as low use model (maybe for Planning).

DeepSeek v4 Pro is not actually that good a model compared to GLM 5.1 and Kimi K2.6. It's an okay coder/thinker for the price.

How so? In my experience trying these models using opencode Go, DeepSeek is superior to GLM 5.1.

If anything, DS4 has 1 million context window, while GLM 5.1 has 200K.

There are also benchmarks comparing the two: https://artificialanalysis.ai/models/comparisons/deepseek-v4...

Personally, when I use open code or routers, I feel that beyond a certain level, the models don't make a huge difference to me. Except for expensive and mediocre models like Gemini. In that sense, Chinese models are pretty good. I usually write code in function or method units and then design and assemble them together. GPT series models are more thorough and better, but I'm not sure if the difference is enormous. It…

The difference in outcome isn't that big but yes, you need to be more rigorous. For instance I've found that the Kimi K2.5 and K2.6 models will comment out failing tests rather than fix a problem they just caused (mistaking them for "pre-existing failures"), so you need to specifically make commented-out tests break the build. I've not personally had that problem with any of the Anthropic or OpenAI models.

I wonder why it's the natural tendency of models to BS or do stuff like this when they don't have the correct answer - it's clear that they can program refusal into them, but for some reason, refusal has to be injected after the fact, and models can't really arrive at the conclusion that they can't answer properly.

The model is natively quantized (i.e. it was trained that way in the first place, so this is not a post-training quantization which degrades performance).

But the huggingface link mentions BF16, F16, and I32?

Not every weight is quantized. For example, those weights which don't take much space or are highly important are left in higher precision. State-of-art quantization of weights is never done uniformly (i.e. to all weights and in the same way).

I really hope we stop using the term "Chinese models". It has this air of Negative connotation. It's the equivalent of calling cars Japanese, which people used to do but now is almost entirely meaningless. You just call them Toyota, Honda, Lexus etc.

Japanese cars is actually a positive qualifier. I'd say anything Japanese motor-powered.
