Common questions
GPT-5.4
Answered from the verified figures on this page rather than general guidance.
How much does GPT-5.4 cost per million tokens?
GPT-5.4 is listed at $2.50 per million input tokens and $15 per million output tokens at standard rates. Output tokens usually dominate real bills, so weigh the output rate more heavily than the input rate. Standard $2.50/$15 per MTok; >272K input billed 2x in / 1.5x out. Cached input $0.25/MTok; batch $1.25/$7.50.
What is GPT-5.4's context window?
GPT-5.4 accepts about 1.05M tokens of context. That only matters if you routinely send very long documents, large codebases, or multi-turn histories that approach that limit.
What is GPT-5.4 best for?
GPT-5.4 is a balanced tier from OpenAI. It suits general production, agentic workflows, knowledge work. A generation behind GPT-5.6; still widely used and well-supported.
