Kimi K3 Offers Better Cost-Performance for Coding Tasks
rohanpaul_ai · x · 2026-07-19
An image compares the performance of Kimi K3 and Fable 5 on software engineering / DeepSWE rollout tasks:
- At a cost of $100, Kimi completes 14.7 tasks compared to Fable's 5.3, giving it a roughly 2.8x advantage in cost-effectiveness.
- The tradeoff is a slower per-rollout time: Kimi takes a median of 66 minutes, while Fable takes 21 minutes.
- A cited note adds that these results may continue to shift once the model is officially released and widely available.
