OpenAI: GPT-5.4 Pro
Analysis Summary
OpenAI's GPT-5.4 Pro is listed with a 1.05M context window, vision and file input, and support for tools and function calling. This feature set could suit long-document analysis and workflows that combine file handling with tool access. However, the supplied data contains no benchmark results for this specific Pro variant, so its reasoning, coding, and agentic performance cannot be established from this record.
Its listed input and output rates are $30 and $180, a substantial cost for routine or high-volume traffic. The larger context and richer workflow options may be relevant for high-value jobs, but they do not establish that this variant outperforms less expensive options. Run a task-specific pilot and compare answer quality and reliability against GPT-5.4 before adoption. Keep it off production paths until its value at that price is demonstrated.
