Early takeaways: from this release, DeepSeek V4 Flash is the model to pay attention to here. It's cheap, effective, and REALLY fast.
The Pro model is slow, not much better in coding reasoning so far when it works, and honestly too unreliable and rate limited to be of much use, currently. Hopefully that improves as new providers host the model. Flash is working fine, and is currently performing competitively with recent releases, but only on agentic workflows. Check back in 24 hours for full combined scoring with tool use and long context for both models.
Many of the frontier Chinese AI labs have released near-frontier models that are just a little bit behind Opus 4.6 in terms of speed, tool use ability, or long context handling. Open weights are winning the AI race, led by China. Crazy couple weeks of releases.
Mimo V2.5 Pro by Xiaomi (not open weights) is actually the best performer of the latest string of Chinese releases in our combined, comprehensive benchmarks, despite getting less attention. Kimi K2.6 is the most interesting open weights release, still. DeepSeek is not the leader in the space anymore.
An interesting pattern with the latest string of Chinese releases is the much better agentic boost (models are not as smart out of the box, but their ability to iterate in a loop with tools makes up most of the difference). Deepseek V4 Flash exemplifying this -- not a smart model on the first try, but it makes up for it over the course of a session.
