Every request is metered at the official rate first, then your progressive B2C discount (60% at the start, up to 70% as cumulative top-ups grow) is subtracted before it touches your prepaid balance. Context window: 272K tokens. Max output: 32K tokens. Reasoning efforts: none, low, medium, high, xhigh.
Best for
- Pipelines tuned and evaluated against GPT-5.4.
- Balanced coding and content workloads.
- Teams migrating gradually to GPT-5.6 Terra.
Good to know
- Reasoning efforts none through xhigh; the max level is exclusive to the GPT-5.6 line.
- Same list price as gpt-5.6-terra — new projects should usually start there.
- Requests above 272K input tokens bill at OpenAI long-context rates: 2× input and 1.5× output on the whole request.
How to use GPT-5.4
Create a free account, generate one key, and point any OpenAI-compatible tool at https://openai.api.apitoken.sale/v1 with model ID gpt-5.4 — Responses and Chat Completions both work, authenticated with Authorization: Bearer. New accounts include $10 of API usage at official prices — enough to test the model before topping up.
Frequently asked questions
How much does the GPT-5.4 API cost?
Officially $2.50 per 1M input tokens and $15 per 1M output tokens. With the apiToken.sale discount that starts at $1/$6 and reaches $0.75/$4.50.
GPT-5.4 or GPT-5.6 Terra?
They share a list price, and Terra is the newer balanced tier — prefer it for new projects. Stay on 5.4 when your prompts and evals are pinned to it.
What is the model ID?
gpt-5.4. One apiToken.sale key and balance covers it alongside every other Claude and GPT model.
