model routing

Sakana AI has released Fugu Ultra v1.1, an update to its multi-model router, claiming performance gains up to 7.9 points over v1.0 and results that beat Anthropic's Fable 5 despite Fable 5 not being part of the router's model pool. All benchmark figures come from Sakana itself and remain unverified.

OpenRouter has released Fusion, a multi-model routing system that processes prompts through parallel expert model panels with web search enabled, then uses a judge model to synthesize consensus, contradictions, and unique insights. Users pay the sum of all underlying model completions rather than a single model price.
