A dedicated public landing page for this synced catalog row.
Synced from the active catalog
Validated for gateway requests
Charged from your UAI balance
Same API key and billing flow
This page exists for direct linking, onboarding, and SEO. The same model row powers /v1/models, the public catalog, the app pricing screen, and request validation for /v1/chat/completions.
The same model route, but with one account, one balance, and one API shape.
The synced capabilities for this row indicate image or vision support, so you can route multimodal requests through the same UAI account and billing flow.
Particle AI: Particle-1 is positioned well for chat UIs, demos, and agent loops where faster turn time matters.
Tool and function-style parameters stay available through the same UAI request surface, so agent stacks do not need a separate provider integration.
