Start a generation run

client.runs.startGeneration(, ?): RunStartGenerationResponse { charged_cost, estimated_seconds, run_id, 6 more }

POST/runs/generation

Starts a model generation run in a project canvas using a prompt, workspace, project, optional model, and optional model parameters. Mutating public API requests support an optional Idempotency-Key header for client retries; duplicate keys within two hours return idempotency_duplicate.
