Kimi K2 Thinking, MiniMax M2 Interleaved Thinking: open models are reaching, or have reached, frontier territory. We now have GPT and Claude Sonnet capable at home, as they are open-weight. Around this time last year, we had the DeepSeek moment, Now is the time for another moment.

Benchmarks show that open models are equal to SOTA closed ones but own experience and real world use shows the opposite. And I really wish they were closer, I run GPT-OSS 120b as a daily driver

Four independent Chinese companies released extremely good open source models in the past few months (DeepSeek, Qwen/Alibaba, Kimi/Moonshot, GLM/Z.ai). No American or European companies are doing that, including titans like Meta. What gives?

The answer is simply that no one would pay to use them for a number of reasons including privacy. They have to give them away and put up some semblance of openness. No option really.

ByteDance’s Volcengine is doing very well offering paid LLM services in China. Their Doubao Seed models are on par with other state-of-the-art models.

To start with, an Epyc server or Mac Studio with 512GB RAM.

How does the mac studio load the trillion parameter model?

By using ~3 bit quantized model with llama.cpp, Unsloth makes good quants:

Note that llama.cpp doesn't try to be production-grade engine, more focused on local usage.

I don’t remeber much details about the situation in 2021. But China is in a period of technological explosion—many things are changing at an incredible speed.

It's absolutely impressive to see China's development. I'm happy my country is slowly but surely moving to China's orbit of influence, especially economically.

if its improving living standards for the people, then its surely is a good thing.

"Not controlled by ideology" is a pretty bold statement to make about a self-declared Communist single-party country. There is always an ideology. You just happen to agree with whatever this one is (Controlled-market Communism? I don't know what the precise term is).

I'd expect the same (fine tuning to be better than mere prompting) for most anything. So a model is or is not "a reasoning model" according to the extent of a fine tune. Are there specific benchmarks that compare models vs themselves with and without scratchpads? High with:without ratios being reasonier models? Curious also how much a generalist model's one-shot responses degrade with reasoning post-training.

The question is: fine-tuning for what? Reasoning is not a particular task, it is a general-purpose technique for directing more compute at any task.

Pivot tokens like 'wait', 'actually' and 'alternatively' are boosted in order to force the model to explore alternate solutions.

Is there anything available already on how to setup a reasoning model and let it 'work'/'think' for a few hours? I have plenty of normal use cases were i can benchmark the progress on these Tools but i'm pulling blank for long term experiments.

You can run them using my project llm-consortium. Something like this:

  > uv tool install llm
  > llm install llm-consortium
  > llm consortium save cns-k2-n2 -m k2-thinking -n 2 --arbiter k2 --min-iterations 10
  > llm -m cns-k2-n2 "Find a polynomial time solution for the traveling salesman problem"
This will run two parallel prompting threads, so two conversations with k2-thinking for 10 iterations.

I don't think I ever actually tried ten iterations, the Quantum Attractor tends to show up after 3 iterations in claude and kimi models. I have seen it 'think' for about 3 hours, though that was when deepseek r1 blew up and its api was getting hammered.

Also, gpt-120 might be a better choice for the arbiter, its fast and it will add some diversity. Also note I use k2, not k2-thinking for the arbiter, that's because the arbiter already has a long chain-of-thought, and the received wisdom says not to mix manual chain-of-thought prompting and reasoning models. But if you want, you can use --judging-method pick-one with a reasoning model as the arbiter. Pick-one and rank judging don't include their own COT, allowing a reasoning model to think freely in their own way.
