Fable 5 got pulled. Fusion rebuilds that level — from the models you can still call, at a fraction of the cost.
Stop waiting for the next model — the next jump in capability is a panel, not a checkpoint. Fusion sends your hardest prompts to several frontier models at once, then a judge weighs where they agree, catches where they contradict, and returns the single strongest answer — cross-checked against the rest. Reach for it on the work that actually matters — deep reasoning, hard coding, research, expert critique — anywhere being wrong costs more than a few extra completions.
Casual chat goes straight to a cheaper default. Coding, agent, and tool-using requests fan out to the panel — where a second opinion actually pays off.
Your prompt hits several frontier models at once — independent attempts that each catch what the others miss.
A judge reads every candidate and returns the single strongest one — cross-checked against the others, not a single model's first try.

print(response.choices[0].message.content)Because fusion runs every panel member plus a judge, a fan-out request is billed as the sum of those underlying completions rather than a single model — and only on the requests that actually fan out. Zero markup.
