OpenAI: GPT-5.4 Mini

GPT-5.4 Mini is a multimodal model from OpenAI that accepts text, images, and files as input. It supports a 400,000-token context window with up to 128,000 tokens of output per request, and it includes tool use and reasoning capabilities. Structured output support is unconfirmed based on available data. At $0.75 per million input tokens and $4.50 per million output tokens, it sits in the budget-to-mid tier of capable multimodal models. Its blended benchmark score of 70.8 covers only three benchmarks, so treat that figure as a partial signal rather than a settled verdict. The coding score of 92.5 stands out and makes it worth shortlisting for development-focused workflows, while the agentic score of 49.8 suggests caution for complex multi-step automation tasks. Teams prioritizing long-context document processing at a moderate cost will find it worth evaluating.
