Fireworks AI is a third-party inference provider. It serves open-weight models from several publishers. Guild calls Fireworks with your API key, and Fireworks bills the calls to your account.

​
Publishers on Fireworks AI

Anthropic and Gemini models aren’t on Fireworks AI. Guild reads the Fireworks catalog and lists only serverless chat models that are ready to use. Models that need a dedicated deployment don’t appear.

​
Model IDs

Write canonical model names, such as kimi-k3 or glm-5.3, in policies and llmPreferences. Fireworks names models differently: it puts them under accounts/fireworks/models/, and spells a version’s dot as p. For example, qwen3.8-2.4t-a95b is accounts/fireworks/models/qwen3p8-2p4t-a95b. Guild converts between the two for you.
