The two models score nearly identically at the top level — K3 at 92.4% and Fable at 92.6% on SWE — but show distinct specializations: K3 excels at terminal/security tasks, symbolic math, and dev tooling, while Fable leads on web, data visualization, and multi-language breadth (Java, Python, C++). The key finding is that routing tasks between the two models using an oracle router — which selects K3 for 72–96% of tasks — achieves state-of-the-art accuracy above either model alone, while delivering up to 50x cost savings compared to using Fable exclusively. Prompt caching is a major driver of K3's cost advantage. The conclusion is that single-model strategies are becoming suboptimal, and mixture-of-models routing is the emerging best practice for agentic AI workloads. ## Full article daily.dev links to this article rather than hosting it.
