Particle-1, a coding model that uses fewer tokens, lands on OpenRouter
- Announcement time
- Review updated
Particle-1, a coding model post-trained from DeepSeek V4.1 Flash, is now on OpenRouter. Particle says that across four coding benchmarks it uses 28–52% fewer output tokens than the base model (about 45% on average) with nearly the same accuracy. Pricing is $0.25 per million input tokens and $1 per million output, with a 1.05M-token context window.
