Quick start

Call GPT 5.4 with the OpenAI Python SDK:

from openai import OpenAI

client = OpenAI()
response = client.chat.completions.create(
    model="gpt-5.4",
    max_tokens=6000,
    messages=[{"role": "user", "content": "Your prompt here"}]
)
# Cost: ~$0.0975 per call at standard rates
# Input:  $2.50/MTok
# Output: $15.00/MTok

What drives api generation cost

Endpoint generation is the most output-heavy code task tracked here: 3K in for the spec, 6K out for handlers, types, validation, and error paths. Output pricing is therefore the whole ballgame, and the gap between a flagship and a mid-tier model at 6K output tokens compounds fast across a large API surface. Generating one resource at a time costs less than one giant multi-resource prompt.

For GPT 5.4 specifically, that means output tokens cost 6.0x more than input, at $15.00 vs $2.50 per MTok. At this use case’s 3,000/6,000 token split, output accounts for 92% of the $0.0975 per-call cost.

Prompt caching: 90% off input tokens

Caching drops input cost from $2.50 to $0.25/MTok. For repeated system prompts, that saves $0.006750 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 5.4 cost for api generation per API call?

A typical api generation call using GPT 5.4 costs about $0.0975 per call. This estimate uses 3,000 input tokens and 6,000 output tokens at standard rates. Standard rates are $2.50 per million input tokens and $15.00 per million output tokens.

Is GPT 5.4 the best model for api generation?

GPT 5.4 scores 84 out of 100 on api generation benchmarks overall. It ranks #4 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 api generation with good quality?

The most affordable model for api generation 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 5.4 to Claude Sonnet 5 saves about 32% per API call.

How can I reduce my GPT 5.4 costs for api generation?

Three strategies lower GPT 5.4 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 $0.0975 to about $0.004875 per call.

How does GPT 5.4 pricing compare to other GPT models?

GPT has 4 other models alongside GPT 5.4 today: GPT 5.5 at $5.00/$30.00 per million tokens (flagship), 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 api generation workload prioritizes quality, cost, or speed.

What context window does GPT 5.4 support?

GPT 5.4 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 api generation, typical calls use 3,000 input and 6,000 output tokens. That is well within this limit, leaving room for longer prompts or multi-turn conversations.
