Quick start

Call GPT 5.6 Sol with the OpenAI Python SDK:

from openai import OpenAI

client = OpenAI()
response = client.chat.completions.create(
    model="gpt-5.6-sol",
    max_tokens=4000,
    messages=[{"role": "user", "content": "Your prompt here"}]
)
# Cost: ~$0.0960 per call at standard rates
# Input:  $4.00/MTok
# Output: $20.00/MTok

Cheapest viable option: Claude Sonnet 5 at $0.0480/call (50% 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 GPT 5.6 Sol specifically, that means output tokens cost 5.0x more than input, at $20.00 vs $4.00 per MTok. At this use case’s 4,000/4,000 token split, output accounts for 83% of the $0.0960 per-call cost.

Prompt caching: 90% off input tokens

Caching drops input cost from $4.00 to $0.40/MTok. For repeated system prompts, that saves $0.0144 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 5.6 Sol cost for code refactoring per API call?

A typical code refactoring call using GPT 5.6 Sol costs about $0.0960 per call. This estimate uses 4,000 input tokens and 4,000 output tokens at standard rates. Standard rates are $4.00 per million input tokens and $20.00 per million output tokens.

Is GPT 5.6 Sol the best model for code refactoring?

GPT 5.6 Sol scores 94 out of 100 on code refactoring benchmarks overall. It ranks #1 across all 20 models in our cross-provider registry. The highest-ranked model for this task is Claude Fable 5 from Claude. That model scores 96/100 on this task type. Confidence scores are a third-party benchmark snapshot from week 29 of 2026. This snapshot is 8 weeks old, so treat the scores as directional and validate against your own evals.

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 5.6 Sol to Claude Sonnet 5 saves about 50% per API call.

How can I reduce my GPT 5.6 Sol costs for code refactoring?

Three strategies lower GPT 5.6 Sol costs for this task type effectively. Prompt caching gives a 90% 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 $0.0960 to about $0.004800 per call.

How does GPT 5.6 Sol pricing compare to other GPT models?

GPT has 4 other models alongside GPT 5.6 Sol today: GPT 5.5 at $5.00/$30.00 per million tokens (flagship), GPT 5.4 at $2.50/$15.00 per million tokens (mid-tier), GPT 5.6 Terra at $2.00/$12.00 per million tokens (mid-tier), GPT 5.6 Luna at $0.20/$1.20 per million tokens (fast / budget). The right choice depends on whether your code refactoring workload prioritizes quality, cost, or speed.

What context window does GPT 5.6 Sol support?

GPT 5.6 Sol supports a context window of 1,050K tokens per API call. This sets the maximum combined length of your input prompt and generated response. For code refactoring, typical calls use 4,000 input and 4,000 output tokens. That is well within this limit, leaving room for longer prompts or multi-turn conversations.
