Suhail announced the launch of particle-1, trained for better token efficiency with noticeably faster end-to-end task completion. The model is built on DeepSeek V4.1 Flash 1017, with a detailed write-up published.

The team's bigger goal is continuous post-training: shipping model improvements as fast as software releases, as a first step toward hillclimbing to efficient intelligence.
