OpenAI: GPT-5.4
Analysis Summary
GPT-5.4 is a high-end OpenAI model with a 53.1 intelligence index and a 71.1 coding index, backed by a 1.05 million token context window. Vision, file handling, tool use, and function calling give it a broad operational range beyond text generation.
That combination makes it suitable for software engineering, long-document analysis, research-heavy SEO, client-facing content, and multi-step agents. The agentic result is strong rather than class-leading, but the overall capability profile is broad enough for a primary agency model. Its input and output prices are also more manageable than the Pro variant.
Design for Online could place GPT-5.4 on demanding client workflows immediately, while routing routine volume to a cheaper model. It is especially attractive where one model must handle documents, code, images, and structured actions.
