OpenAI: GPT-5.4
Analysis Summary
GPT-5.4 is OpenAI's flagship model at the time of its release, with an intelligence index of 51.4 and a coding index of 57.2 that place it firmly in the world-class tier. Its agentic index of 72.4 confirms strong multi-step tool use and autonomous task execution. The 1.05M token context window is among the largest available, enabling full-codebase analysis, long-document reasoning, and extended agentic sessions without truncation.
For businesses, GPT-5.4 is a strong fit for the most demanding workloads: complex software engineering, autonomous coding agents, long-document analysis, and high-stakes client-facing content. Vision and file input support, combined with tool use and function calling, make it a broad-capability model that can consolidate multiple specialist tools. Instruction following and long-context reasoning scores are both strong.
The main trade-off is cost: at $2.50 input and $15.00 output per million tokens, it is expensive for high-volume use. Teams should reserve it for high-value tasks and pair it with cheaper models for routine calls. For organisations where output quality is critical, it remains a top-tier choice.
