Particle-1 lands on AI Gateway: a software-engineering model built to finish coding tasks with fewer tokens
Particle AI's Particle-1 is now available on AI Gateway, giving developers a unified endpoint for the model. Particle-1 is post-trained on DeepSeek V4.1 Flash, and Particle describes its gains as shorter reasoning, fewer rounds of trial and repair, and more focused exploration, aimed at debugging, planning code changes and breaking down multi-step engineering problems. It offers a 1M-token context window for working with code and extended task histories.
