Open-weights AI models have become good enough
Open-weights AI models have become good enoughJuly 22, 2026Over the past week I've played around with Kimi K3 by Moonshot AI and Qwen 3.8 Max by Alibaba. Both are large Chinese open-weight models (weights promised to be released soon) and tout benchmarks showing they're as capable as the frontier western models (Fable 5 by Anthropic and GPT-5.5 Sol by OpenAI). I wouldn't go that far, but these are really capable models.

Both are large Chinese open-weight models (weights promised to be released soon) and tout benchmarks showing they're as capable as the frontier western models (Fable 5 by Anthropic and GPT-5.5 Sol by OpenAI). I wouldn't go that far, but these are really capable models. In my AI-coding tests, both have performed really well. Compare the test mini-games on my vibe-coding benchmark generated by Fable, Sol, K3 and Qwen. In a more serious test, building a web app to a provided spec, K3, Qwen and Fable generated very similar results.
