Kimi is capable model but it needs a very good harness. With a good harness it is a very capable model. But it can get into all kinds of issues (loops and such) something that frontier models do not. As I said, you can blame the model, but it is nothing that the harness cannot take care of more deterministically.

Which harness do you recommend using then for a model like kimi 2.6, Opencode or something else?

>There is more to American economy than big tech. Most of the stock market valuation is big-tech, and most of people's retirements are the stock market, so... if the AI bubble bursts a lot of the US will be affected.

I do not know why this is downvoted. This is true.

We have our own... so I was making the comment form our own experience working with the model.

It is a lot trickier to use kimi compared to sonnet - hence why it seems that sonnet is more powerful while I think it is down to the harness.

It absolutely does matter. The enshittification will go unnoticed at first but I'm already finding my favourite frontier models severely nerfed, doing incredibly dumb stuff they weren't in the past. We need open weight models to have a stable "platform" when we rely on them, which we do more and more.

Most people won't roll out their own K2 deployment across rented GPUs, so in that sense it doesn't matter that much, they'll be using a paid service which is just as much of a black box as Claude or ChatGPT. For example, on OpenRouter you can select a provider which state they use a given open model, but you have no idea what actually goes on behind the curtains, which quantization levels they use and so on. That sai…

Well you can rent a capable node for a few hours for like $50, install Kimi yourself and verify occasionally whether it works just like in cloud providers.

How did you make your own harness, I am curious to know more about the building process and please feel free to share your harness.

If someone were to not use your harness and rather use some stock harness though, what is the one that you would recommend? I am curious about that too.

Kimi is nowhere near GPT or Opus unfortunately. I really wish it was. I’m running evals where models have to generate code that produces 3D models and it’s obvious that it lacks spatial understanding and makes many more code errors before it succeeds. Maybe it’s better in one particular case here and there and I think this blog post is example of that.

Not everyone needs 3D models to be fair.

> Xiaomi confirming that weights for their newer V2.5 Pro model are dropping soon

This has already happened.

I have downloaded both the big Pro model and the smaller but multimodal MiMo-V2.5.

https://huggingface.co/XiaomiMiMo/MiMo-V2.5-Pro-Base

https://huggingface.co/XiaomiMiMo/MiMo-V2.5-Base

The download of MiMo-V2.5-Pro takes 963 GB, while that of MiMo-V2.5 takes 295 GB.

For comparison, the download of Kimi-K2.6 takes 555 GB.

These posts are going to be a constant for the next year, because there's no objective way to compare models (past low-level numbers like token generation speed, average reasoning token amount, # of parameters, active experts, etc). They're all quite different in a lot of ways, they're used for many different things by different people, and they're not deterministic. So you're constantly gonna see benchmarks and test…

Unfortunately, you're probably right, but the cock measuring contest is going to keep escalating because the billionaires and VC backers need to _win_. And the Psychosis is going to produce some horrible collateral damage.
