How much does GPT-5.4 cost on ATP Token?

List rates for GPT-5.4 (API id gpt-5.4): input $2.50 / output $15.00 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 via API?

Create a project API key, enable the API id gpt-5.4 (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". See the Quickstart on this page and the docs.

What are the context and capabilities of GPT-5.4?

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 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

OpenAI

GPT-5.4 is OpenAI's frontier model for professional work, folding recent advances in reasoning, coding, and agentic workflows into a single model. It is particularly strong at coding agents, computer-use automation, deep research, and document-heavy deliverables such as spreadsheets and presentations. OpenAI documents a 1,050,000-token context window with text and image input, built to sustain long-horizon tool use across extended sessions. On ATP Token you call it with a project-scoped key and spend debits project credits at the list rates below.

OpenAI documents a 1,050,000-token context window for GPT-5.4; very long prompts may use provider long-context rate tiers. ATP debits the list rates shown below per completed request.

Where it fits

Good fit

Coding agents that plan, edit, and verify across a large repo
Computer-use automation and long-horizon tool chains
Deep research and analysis over long documents within the 1.05M window
Office deliverables — spreadsheets, presentations, structured documents

Usually not ideal

Lowest-cost bulk classification or simple chat at scale (consider GPT-5.6 Luna)
Token-efficiency-first agent loops — GPT-5.5 targets the same work with fewer tokens

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.
