Key point

Post-trained on DeepSeek V4.1 Flash, the model targets software engineering tasks with shorter reasoning and fewer tokens.

Particle-1 from Particle AI is now available on AI Gateway, post-trained on DeepSeek V4.1 Flash to complete software engineering tasks using fewer tokens.
The model features a 1M-token context window designed for debugging, planning code changes, and breaking down multi-step engineering problems.
AI Gateway provides a unified API with no markup on provider pricing and no platform fee on inference, including Bring Your Own Key (BYOK) requests.
Users can integrate the model via Vercel CLI for agents like Claude Code, Codex, and Cursor, or access it through the model playground.
