Particle AI

Commercial provider · 1 model tracked

US company training models to solve tasks in fewer tokens, so the same work costs less. Its first model, Particle-1 (launched 2026-10-28), is an agentic coding model post-trained from DeepSeek V4.1 Flash with reinforcement learning. Particle sells it per token on its own OpenAI-compatible API, with half-price off-peak hours and a Flex tier at a further 50% off, and the same API also serves DeepSeek V4.1 Flash and GLM 5.3 Flash. Particle states no founding year on its own pages, so none is published here.
