Particle-1 is now available on AI Gateway
Particle-1 adds another coding model to Vercel AI Gateway, with a 1M-token context window and support for Claude Code, Codex and Cursor after CLI setup.
Particle-1 is post-trained on DeepSeek V4.1 Flash and targets software engineering tasks with fewer tokens. It has a **1M-token context window** and is available through Vercel AI Gateway as `particle/particle-1`.
Try it for debugging, code-change planning or multi-step tasks in your coding agent. Set `AI_GATEWAY_API_KEY`, install the latest Vercel CLI, run setup and select the model.

Particle describes its reasoning and repair loops as more efficient; the material provides no comparative measurements. Gateway also offers usage and cost tracking, routing and retries.
Particle-1 adds another coding-focused, million-token model route through AI Gateway, with an efficiency claim but no comparative measurements. It broadens the candidates for debugging and multi-step work without establishing an advantage over other long-context options; Gateway routing and cost tracking can support evaluation, not substitute for it.
