How much does GPT-5.4 Pro cost on ATP Token?

List rates for GPT-5.4 Pro (API id gpt-5.4-pro): input $30.00 / output $180.00 per 1M tokens. Billing uses credits (1 USD = 100 credits), debited from the project balance per completed request. There is no monthly platform fee; see Pricing for the minimum top-up.

How do I call GPT-5.4 Pro via API?

Create a project API key, enable the API id gpt-5.4-pro (not the display name) on that project’s allowlist, point an OpenAI-compatible SDK at https://api.atptoken.ai/v1, and set model to "gpt-5.4-pro". See the Quickstart on this page and the docs.

What are the context and capabilities of GPT-5.4 Pro?

Vendor documentation lists a context window of about 1,050,000 tokens. Capability flags (thinking, tools, vision) follow the gateway model catalog — treat the catalog visible to your key as operational truth. Vendor: OpenAI.

Who can use GPT-5.4 Pro on ATP?

Only models on a project’s allowlist can be called with that project’s key (match the API id). Organization → workspace → project governance, per-request logs, and credit budgets are managed in the ATP Console.

GPT-5.4 Pro

OpenAI

GPT-5.4 Pro is the maximum-performance tier of OpenAI's GPT-5.4 family, released in the API and Codex for people who want the strongest results on complex tasks. It is particularly suited to hard multi-step reasoning, demanding code generation and review passes, and agent runs where a failed step costs more than the premium rate. It shares the family's documented 1.05M-token context and vision input at a substantially higher list rate than standard GPT-5.4, so route only the hardest calls here. On ATP Token, allowlist this id on the projects that need it; calls debit project credits.

OpenAI documents a 1.05M-class context window for the GPT-5.4 family (including Pro). Long-context sessions may carry provider surcharges; ATP settles at the list rates on this page.

Where it fits

Good fit

Hard multi-step reasoning where retry cost exceeds the rate premium
Deep code review and bug finding on critical paths
Final-pass verification behind a cheaper drafting model

Usually not ideal

High-volume chat, extraction, or routing a cheaper tier can finish
Experiments without a project spend cap

On ATP

The same governance applies to every model on the gateway:

Project API key — spend and revocation bound to one project
Model allowlist — only enabled models may be called
Credits — 1 USD = 100 credits, debited per completed request
Per-request logs — model, key, project, credits for audit

Cost estimator

A list-price estimate for a month of traffic. Actual spend follows each completed request.
