OpenAI: GPT-5.4 Mini
Analysis Summary
OpenAI GPT-5.4 Mini is a high-capability model from OpenAI with a coding index in the world-class range and a strong agentic index. Vision, tool use, and function calling are all supported, giving it broad capability across multimodal, agentic, and coding workflows. Instruction-following and long-context reasoning scores are strong, and the terminal benchmark is among the best in its intelligence tier.
For businesses, it is well suited to software engineering, autonomous coding agents, document analysis with image input, and client-facing workflows where answer quality and reliability matter. The 400K context window supports large codebase and document tasks. As an OpenAI flagship, it benefits from wide enterprise adoption, strong tooling integration, and reliable API support.
At $0.75 input and $4.50 output per million tokens, output pricing is on the higher side, making it better suited to high-value tasks than bulk, high-volume automation. Teams already in the OpenAI ecosystem will find it a strong upgrade path for coding and agentic work.
