Using Claude Opus 4.5 in your workflow

Sorceress brings Anthropic models into a shared API catalog. Select this model explicitly, check its supported inputs, and keep your API key on your server. Model capabilities differ; the schema and options on this page describe this entry rather than every model from the same brand.

  • Draft, explain and refine content in a conversation.
  • Use a consistent chat endpoint while choosing a model suited to your task.

Pricing and availability

Sorceress pricing is awaiting activation. The reference catalog lists 285 credits / M input tokens, 1430 / M output; that reference is not a Sorceress quote. This entry cannot currently be invoked through Sorceress.

Completion, results and billing

Save the job identifier returned by asynchronous requests and poll the jobs endpoint until the job succeeds or fails. Do not resubmit a generation just because it is still processing. Chat returns a completed reply and usage details. A multi-step workflow can include separately billed successful steps even if a later step fails. Keep returned asset links with your project, and consult each action for its output format.

Coding agents can discover the current catalog and input requirements from the Sorceress agent instructions. Use a Sorceress key; provider credentials stay on the server.
