Low API Price ≠ Cheap: Kimi K3's Low Cache Hit Rate Hurts Real-World Costs
peterjliu · x · 2026-07-29
A developer testing the Kimi K3 model within a multi-model orchestration (Compound) architecture pointed out that its input-cache hit rate on Fireworks AI is currently underwhelming, critically impacting cost-efficiency.
The author emphasizes that while Kimi's API pricing is lower, the dominant cost variable for real-world workloads is the input-cache hit rate. Thus, looking solely at the nominal API price does not reflect the actual production costs of running the model.
