Fusion
Ask two or three distinct chat models and return their answers plus a synthesis in one non-streaming response. Accepts organization API keys or CLI inference OAuth credentials; an active paid Fusion entitlement is required. Each participant and the synthesis are billed independently and enforce credential spend caps. HTTP 200 can contain complete, partial, or failed status; inspect per-model errors. All-Confidential sets are supported, but mixed Confidential sets, Encrypted requests, and function tools are rejected. Browser sessions retain CSRF protection.
