Fusion turns a prompt into a small multi-model deliberation. A panel of expert models (Quality preset: Claude Opus, GPT, and Gemini Pro; Budget preset: Gemini Flash, DeepSeek V3.2, and Kimi) analyzes the prompt in parallel with web search and web fetch enabled, then a judge model synthesizes their responses into a structured analysis — consensus, contradictions, partial coverage, unique insights, and blind spots — and writes the final answer. Reach for it when a single model isn't enough: research, expert critique, or anywhere the cost of being wrong outweighs a few extra completions. Because every panel member plus a judge call runs, the request is priced as the sum of those underlying completions. Available with a user-owned API key (BYOK).
