Fireworks AI tested Kimi K3 against Fable on 1,000 agentic tasks. K3 outperformed in security, crypto, and long terminal loops, while Fable excelled in multi-language and web/data viz tasks.

By implementing per-task auto routing, the system achieved 93% accuracy—surpassing both individual models—at up to 50x lower cost than Fable on long loops.

Notably, the router sends 72-96% of traffic to K3, indicating that the frontier model is becoming a fallback rather than the default choice.
