New: every message picks a fast or a slow model

Fireworks AI

Fireworks AI provides APIs for serverless model inference, fine-tuning, deployments, datasets, evaluations, and account management.

What agents can do

Actions9

  • Create chat completion

    Generate one non-streaming OpenAI-compatible chat completion from role-based messages using a caller-supplied Fireworks model or deployment ID.

  • Create embeddings

    Create embedding vectors for one or more caller-provided inputs using a caller-supplied Fireworks embedding model.

  • Generate model response

    Generate one non-streaming Responses API result, optionally continuing a stored response or using function, MCP, or SSE tools; storage is off by default.

  • Get deployment

    Return configuration and serving status for one Fireworks deployment without scaling or modifying it.

  • Get model

    Return metadata and status for one model resource in a Fireworks account; this does not test whether the model can serve inference.

  • List accounts

    Return one page of Fireworks accounts accessible to the API key so an agent can obtain account IDs for model and deployment discovery.

  • List deployments

    Return one page of deployment resources in a Fireworks account for deployment ID discovery and serving-capacity and status inspection.

  • List models

    Return one page of model resources in a Fireworks account for model-ID discovery and status inspection; availability for inference is not guaranteed.

  • Rerank documents

    Rank a provided document list by relevance to a query using an optional caller-supplied Fireworks reranker model.

How it connects

You paste an API key from Fireworks AI on a page Composio hosts, so the key never passes through Definable.

Keep the connection to yourself or share it with your workspace. Any action that writes or sends can wait for your approval.
