OpenRouter's Fusion API matches Claude Fable 5 at half price
Fusion fans prompts to multiple models, using a judge and synthesizer to produce a grounded answer, achieving DRACO benchmark scores within 1% of Claude Fable 5 at roughly half the cost. The launch follows U.S. export controls that forced Anthropic to suspend Fable 5 globally, creating a market gap.
