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=600,
messages=[{"role": "user", "content": "Your prompt here"}]
)
# Cost: ~$0.0280 per call at standard rates

What drives invoice parsing cost
Invoices are short, highly repetitive documents processed in bulk: the ideal batch API workload. Per-document cost is low; total cost is set by volume and by whether you are paying full rate for a job that could have run asynchronously overnight at a discount. The extraction schema is constant, so it should never be paying full input rate either.
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 2,000/600 token split, output accounts for 64% of the $0.0280 per-call cost.

Standard token rates
| Direction | $/MTok | Tokens per call |
|---|---|---|
| Input | $5.00 | 2,000 |
| Output | $30.00 | 600 |
Prompt caching: 90% off input tokens
Caching drops input cost from $5.00 to $0.50/MTok. For repeated system prompts, that saves $0.009000 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 invoice parsing per API call?
A typical invoice parsing call using GPT 5.5 costs about $0.0280 per call. This estimate uses 2,000 input tokens and 600 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 invoice parsing?
GPT 5.5 scores 87 out of 100 on invoice parsing benchmarks overall. It ranks #4 across all 20 models in our cross-provider registry. The highest-ranked model for this task is GPT 5.6 Terra from GPT. That model scores 90/100 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 invoice parsing with good quality?
The most affordable model for invoice parsing above 80/100 quality is GPT 5.6 Luna. It comes from GPT at $0.20 per million input tokens. Output costs $1.20 per million tokens with a quality score of 89/100. Switching from GPT 5.5 to GPT 5.6 Luna saves about 96% per API call.
How can I reduce my GPT 5.5 costs for invoice parsing?
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 $0.0280 to about $0.001400 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 invoice parsing 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 invoice parsing, typical calls use 2,000 input and 600 output tokens. That is well within this limit, leaving room for longer prompts or multi-turn conversations.
