Send one prompt to N large language models in parallel through OpenRouter, collect every response with token, latency, and cost metadata, then have a configurable judge model synthesize one higher-quality answer. Use Fusion Engine as a Python library, CLI, FastAPI service, or OpenAI-compatible /v1/chat/completions API for AI agents that need multi-model LLM orchestration, fused tool calling, transparent model comparison, and eval-driven panel tuning. If you are looking for a Fusion API , OpenRouter Fusion , Fusion Fable , or Fable Fusion style system, this project provides the self-hosted Python implementation: model panels, judge prompts, OpenRouter routing, OpenAI-style chat completions, and benchmarkable fusion results. One prompt in → many models answer → one fused answer out. You control the panel composition, the judge prompts, and where it runs — no vendor lock-in. Widget What Fusion Engine Gives You --- --- Fusion API Self-hosted multi-model fusion with transparent cost, token, and latency data. OpenRouter Fusion Bring your own OpenRouter models and panel definitions instead of using a black box.
