Fireworks says Kimi K3 can handle most agent traffic and route the rest
A quoted Fireworks AI post describes an evaluation of Kimi K3 versus Fable on about 1,000 agentic tasks. The result was not a simple frontier-model win, but a specialization story:
- K3 performed better on security, crypto, and long terminal loops
- Fable did better on multi-language tasks and web/data visualization
- A per-task router reached 93% accuracy
- The router sent 72–96% of traffic to K3, making the frontier model a fallback rather than the default
- The setup was claimed to be up to 50× cheaper than Fable on long loops
The post says Kimi K3 will be coming to Fireworks on July 27.
