Cheapest viable option: Claude Sonnet 5 at $0.0480/call (33% less, 93/100 quality).
What drives code refactoring cost
Refactoring sends existing code and gets a rewritten version back, so input and output are roughly symmetric, unusual for a code task. That symmetry means neither rate dominates and total cost tracks the size of the file. The practical lever is scope: refactoring one module per call rather than a whole package keeps you off the long-context pricing tier, where some providers re-rate the entire request.
For Claude Sonnet 4.6 specifically, that means output tokens cost 5.0x more than input, at $15.00 vs $3.00 per MTok. At this use case’s 4,000/4,000 token split, output accounts for 83% of the $0.0720 per-call cost.

Standard token rates
| Direction | $/MTok | Tokens per call |
|---|---|---|
| Input | $3.00 | 4,000 |
| Output | $15.00 | 4,000 |
Prompt caching: 90% off input tokens
Caching drops input cost from $3.00 to $0.30/MTok. For repeated system prompts, that saves $0.0108 per call.
Batch API: 50% off all tokens
Submit requests asynchronously and receive 50% off all token costs. This works best for offline pipelines where latency requirements are flexible.
