## AI overview

OpenRouter introduces Fusion, a service that sends a prompt to multiple models in parallel and uses a judge model to synthesize their responses. On the DRACO deep research benchmark, model panels outperformed individual models, including a budget panel that scored above GPT-5.5 and Claude Opus 4.8 at half the cost. The article notes that the comparison involving Fable 5 used 93 scored tasks because content filters blocked seven tasks, and that the results are specific to a text-only, English-only benchmark whose scores vary with the judge model. Fusion can be called through an API, a server tool, or a chat interface; the article suggests coding models could invoke it selectively for research or architecture questions, while cautioning that it is not a drop-in coding model.
