Frequently Asked Questions
What is GPT-5.4 designed to do best?
OpenAI positions GPT-5.4 as a model for complex professional work, especially documents, spreadsheets, presentations, coding, and tool-using workflows. In ChatGPT, OpenAI says GPT-5.4 Thinking is stronger at spreadsheet editing, polished frontend code, slideshow creation, and document understanding.
Is GPT-5.4 available in Canada?
Yes. OpenAI launched GPT-5.4 across ChatGPT, the API, and Codex on 5 March 2026, and the company separately said its ChatGPT for Excel beta is rolling out in Canada for Business, Enterprise, Edu, Teachers, Pro, and Plus users.
How much does GPT-5.4 cost through the API?
OpenAI lists gpt-5.4 at $2.50 per million input tokens, $0.25 per million cached input tokens, and $15 per million output tokens. gpt-5.4-pro is listed at $30 per million input tokens and $180 per million output tokens.
Should teams replace existing workflows right away?
Not automatically. GPT-5.4 looks most useful where a team already mixes documents, spreadsheet models, code changes, and tool use in one flow, so the safer move is to benchmark correction time, token spend, and governance needs before a broad rollout. That recommendation is an inference from OpenAI's workflow-first launch across ChatGPT, Codex, Excel, and the API.
