Particle-1, a model post-trained on DeepSeek V4.1 Flash, is now on Vercel AI Gateway

Vercel says Particle-1 (particle/particle-1) is now available on AI Gateway, its unified endpoint for model providers. Vercel says the model is post-trained on DeepSeek V4.1 Flash and completes engineering tasks with fewer tokens, and suggests it for debugging, planning code changes and breaking down multi-step problems.
