How much does GPT-5.4 Mini cost per million tokens?
GPT-5.4 Mini is listed at $0.75 per million input tokens and $4.50 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 $0.75/$4.50 per MTok; cached input $0.075/MTok; batch $0.375/$2.25.
What is GPT-5.4 Mini's context window?
GPT-5.4 Mini accepts about 400K 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 Mini best for?
GPT-5.4 Mini is a balanced tier from OpenAI. It suits high-volume calls, mixed workloads, cost-sensitive production. 400K context (vs 1.05M on GPT-5.4/5.5/5.6); verify long-context needs.
