Quick start

Call GPT 5.5 with the OpenAI Python SDK:

from openai import OpenAI

client = OpenAI()
response = client.chat.completions.create(
    model="gpt-5.5",
    max_tokens=2000,
    messages=[{"role": "user", "content": "Your prompt here"}]
)
# Cost: ~$0.0850 per call at standard rates
# Input:  $5.00/MTok
# Output: $30.00/MTok

Cheapest viable option: Claude Sonnet 5 at $0.0300/call (65% less, 96/100 quality).

What drives bug detection cost

Bug detection sends a file and gets back a short list of suspected defects, so input dominates and output stays small. That makes it cheap per call and tempting to run continuously, which is the real cost driver: frequency, not per-call price. Caching the unchanged parts of the codebase and running only on changed files is worth more than switching models.

For GPT 5.5 specifically, that means output tokens cost 6.0x more than input, at $30.00 vs $5.00 per MTok. At this use case’s 5,000/2,000 token split, output accounts for 71% of the $0.0850 per-call cost.

Prompt caching: 90% off input tokens

Caching drops input cost from $5.00 to $0.50/MTok. For repeated system prompts, that saves $0.0225 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 5.5 cost for bug detection per API call?

A typical bug detection call using GPT 5.5 costs about $0.0850 per call. This estimate uses 5,000 input tokens and 2,000 output tokens at standard rates. Standard rates are $5.00 per million input tokens and $30.00 per million output tokens.

Is GPT 5.5 the best model for bug detection?

GPT 5.5 scores 90 out of 100 on bug detection benchmarks overall. It ranks #3 across all 20 models in our cross-provider registry. The highest-ranked model for this task is Claude Sonnet 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 bug detection with good quality?

The most affordable model for bug detection 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 96/100. Switching from GPT 5.5 to Claude Sonnet 5 saves about 65% per API call.

How can I reduce my GPT 5.5 costs for bug detection?

Three strategies lower GPT 5.5 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 $0.0850 to about $0.004250 per call.

How does GPT 5.5 pricing compare to other GPT models?

GPT has 4 other models alongside GPT 5.5 today: GPT 5.4 at $2.50/$15.00 per million tokens (mid-tier), GPT 5.6 Sol at $4.00/$20.00 per million tokens (flagship), 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 bug detection workload prioritizes quality, cost, or speed.

What context window does GPT 5.5 support?

GPT 5.5 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 bug detection, typical calls use 5,000 input and 2,000 output tokens. That is well within this limit, leaving room for longer prompts or multi-turn conversations.
