How Much Does It Cost to Generate & Review Python Code with AI?
Python code reviews typically involve passing entire files (1,500-3,000 tokens of input) and generating small diff patches (200-500 tokens of output).
Typical monthly workload
- Input tokens
- 3,000,000
- Output tokens
- 1,200,000
- Requests / day
- 500

Recommended setup
Run standard function completion and unit tests through DeepSeek V3 ($0.14/M); reserve Claude Sonnet for multi-file architectural refactoring.

Computed from list prices and the workload above (3,000,000 input and 1,200,000 output tokens per month), with no caching or batch discounts. Real bills vary.
How to cut this cost
- Strip Docstrings and Comments on Re-submission
When sending code for iterative refactoring, remove unchanging boilerplate to reduce token counts by 25%.
- Use Prompt Caching for Repository Schemas
Enable Anthropic prompt caching on your project guidelines to get a 90% discount on repeated context tokens.
