A research lab most builders have never heard of just claimed it beats Fable 5. The twist is that Sakana Fugu isn't a model at all. You hit one endpoint, and behind it a trained orchestrator picks from a pool of frontier models, delegates the work, verifies it, and stitches the answer back together. It can even call copies of itself.

A week earlier, OpenRouter shipped Fusion: the same bet in a different shape. Stop leaning on one model. Send the prompt to a panel and let a judge merge the answers. Two labs, one idea.

So this video answers the question underneath both launches: is a mixture of specialist models actually better than one general-purpose model?
