Particle-1 is now available on AI Gateway

Particle AI's Particle-1 model is now available on Vercel's AI Gateway, accessed under the model name `particle/particle-1`. Particle-1 is post-trained on DeepSeek V4.1 Flash and targets software engineering tasks with fewer tokens, which Particle AI describes as producing shorter reasoning, fewer rounds of trial and repair, and more focused exploration, and it carries a 1M-token context window. Vercel said AI Gateway reflects provider pricing with no markup and charges no platform fee on inference, including on Bring Your Own Key requests.

Particle-1 https://vercel.com/ai-gateway/models/particle-1 from Particle AI is now available on AI Gateway https://vercel.com/docs/ai-gateway . It is post-trained on DeepSeek V4.1 Flash, with a focus on completing software engineering tasks using fewer tokens. Particle describes the gains as shorter reasoning, fewer rounds of trial and repair, and more focused exploration. Use it for debugging, planning code changes, and breaking down multi-step engineering problems. Particle-1 has a 1M-token context window for working with code and extended task histories. Set AI GATEWAY API KEY in your environment. Use particle/particle-1 as the model name: To use it in Claude Code, Codex, Cursor, and more, install the latest version of Vercel CLI and run setup: Then select particle/particle-1 in the agent.
