# Cost: ~$0.0690 per call at standard rates

Cheapest viable option: Claude Sonnet 5 at $0.0460/call (33% less, 96/100 quality).
A pull request review carries the diff, the surrounding context, and often the PR description (heavy input, moderate output). Cost scales with PR size rather than with how much the model says, so the expensive reviews are the ones nobody wants to read anyway. Splitting large PRs is a cost control as much as an engineering practice.
For Kimi K3 specifically, that means output tokens cost 5.0x more than input, at $15.00 vs $3.00 per MTok. At this use case’s 8,000/3,000 token split, output accounts for 65% of the $0.0690 per-call cost.
| Direction | $/MTok | Tokens per call |
|---|---|---|
| Input | $3.00 | 8,000 |
| Output | $15.00 | 3,000 |
Caching drops input cost from $3.00 to $0.30/MTok. For repeated system prompts, that saves $0.0216 per call.
Submit requests asynchronously and receive 0% off all token costs. This works best for offline pipelines where latency requirements are flexible.

A typical pr review call using Kimi K3 costs about $0.0690 per call. This estimate uses 8,000 input tokens and 3,000 output tokens at standard rates. Standard rates are $3.00 per million input tokens and $15.00 per million output tokens.
Our benchmark data does not yet include a pr review ranking for Kimi K3. We recommend testing it against your own evaluation criteria before production usage.
The most affordable model for pr review above 80/100 quality is Claude Sonnet 5. It comes from Claude at $2.00 per million input tokens. Output costs $10.00 per million tokens with a quality score of 96/100. Switching from Kimi K3 to Claude Sonnet 5 saves about 33% per API call.
Three strategies lower Kimi K3 costs for this task type effectively. Prompt caching gives a 90% discount on input tokens when reusing system prompts. The batch API gives 0% off all tokens for asynchronous processing workloads. Prompt optimization reduces token counts through more concise instructions and context windows. Combining caching with batching brings your cost from $0.0690 to about $0.006900 per call.
Moonshot (Kimi) has 1 other models alongside Kimi K3 today: Kimi K2 at $0.95/$4.00 per million tokens (mid-tier). The right choice depends on whether your pr review workload prioritizes quality, cost, or speed.
Kimi K3 supports a context window of 1M tokens per API call. This sets the maximum combined length of your input prompt and generated response. For pr review, typical calls use 8,000 input and 3,000 output tokens. That is well within this limit, leaving room for longer prompts or multi-turn conversations.
