About Particle-1
Particle-1 is the debut model from Particle AI, listed on OpenRouter since 2026-10-28 at $0.05/$0.50 per million tokens with a 1M context. No benchmark tables and no leaderboard placement exist yet from any of the four tracked sources, so the AMR score is a conservative provisional anchor in the small-vendor entry tier (cf. Laya 1) with zero scores recorded - it should not be read as a measured capability estimate and will be replaced the moment any benchmark lands.
