A cascading Kimi-to-Sol-to-Fable strategy reaches 89.9% task coverage at $9.24

A cascading model strategy can outperform single-model setups by escalating only when cheaper models fail.
The example in the post routes tasks through Kimi K3, then GPT-5.6 Sol, then Fable 5. With one verifier-driven failover, it reaches 85.6% at $7.30 per task; adding a third model raises coverage to 89.9% at $9.24 and nearly reaches the oracle ceiling.
