Compare 14 AI models for code refactoring. Prices shown at 10K calls/month with default token counts.
Code generation tasks send a natural language prompt and receive executable code back. Token usage tends to be input-heavy with system instructions and added context. Output scales with the complexity of the code the model generates.
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.

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. Across the 14 models we track, a typical call uses about 4,000 input and 4,000 output tokens.
