## Summary

Thinking Machines Lab released Inkling 2 Small, a 594B-parameter MoE model that Artificial Analysis says is the highest-scoring open-weight model outside China. Its technical blog names Moonshot AI's Kimi K3 as a source of later pretraining data, which the article says was sampled from earlier models and then filtered. Per the source, Thinking Machines plans to release the weights under Apache 2.0 next week, while Artificial Analysis lists the release date as unconfirmed.

## Why it matters

The article traces where Inkling 2 Small's training data came from, showing how U.S. labs now draw on Chinese open-weight models for agent trajectories.
