Kimi K3.1 Kibitz is now confirmed to be a very affordable model, similar to GLM 5.3, I just got this new test on Arena and so far my results have been pretty mixed, in some tests Kibitz performs at the level of GPT 6 Astra Medium or Opus 5.5 Medium, while in others the quality considering how good some of these results are and how affordable the model is expected to be, I'm really looking forward to seeing what Kimi has been working on these past few months

My prediction is that Kimi K3.1 could become the best open weight AI model we've seen so far, and if it really delivers this level of performance at such a low price, it could put some serious pressure on Zhipu's upcoming GLM 5.4 and GLM 5.5 models, which are expected next month. The competition between these Chinese AI labs is getting more interesting with every release, and the best part is that we're the ones who benefit from all of this, getting better models, faster performance and lower prices

@notjazii I'm getting Kibitz in about 1 out of every 4 prompts, so I'd recommend running several tests in parallel to increase your chances, it's incredible how good this model is!
