Quick start

Call GPT 4.1 with the OpenAI Python SDK:

from openai import OpenAI

client = OpenAI()
response = client.chat.completions.create(
    model="gpt-4.1",
    max_tokens=4000,
    messages=[{"role": "user", "content": "Your prompt here"}]
)
# Cost: ~$0.0400 per call at standard rates
# Input:  $2.00/MTok
# Output: $8.00/MTok

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 GPT 4.1 specifically, that means output tokens cost 4.0x more than input, at $8.00 vs $2.00 per MTok. At this use case’s 4,000/4,000 token split, output accounts for 80% of the $0.0400 per-call cost.

Prompt caching: 75% off input tokens

Caching drops input cost from $2.00 to $0.50/MTok. For repeated system prompts, that saves $0.006000 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.

Frequently asked questions

How much does GPT 4.1 cost for code refactoring per API call?

A typical code refactoring call using GPT 4.1 costs about $0.0400 per call. This estimate uses 4,000 input tokens and 4,000 output tokens at standard rates. Standard rates are $2.00 per million input tokens and $8.00 per million output tokens.

Is GPT 4.1 the best model for code refactoring?

Our benchmark data does not yet include a code refactoring ranking for GPT 4.1. We recommend testing it against your own evaluation criteria before production usage.

What is the cheapest model for code refactoring with good quality?

The most affordable model for code refactoring 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 93/100. Switching from GPT 4.1 to Claude Sonnet 5 saves about -20% per API call.

How can I reduce my GPT 4.1 costs for code refactoring?

Three strategies lower GPT 4.1 costs for this task type effectively. Prompt caching gives a 75% discount on input tokens when reusing system prompts. The batch API gives 50% 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 $0.0400 to about $0.005000 per call.
