Best estimate from public evidence; the vendor did not disclose every value. Particle AI describes Particle-1 as a token-efficient coding model post-trained on DeepSeek V4.1 Flash; no weights are released. Counts are inherited from the MIT DeepSeek V4.1 Flash base (748B total / 16B active); the open base does not make this API checkpoint open.
