OpenAI: GPT-5.4 Pro
Analysis Summary
GPT-5.4 Pro is positioned as a premium OpenAI model with a 1.05 million token context window, vision, file input, tool use, and function calling. Those capabilities suit large document reviews, complex content operations, and workflows that need structured interaction with external systems.
For client work, the long context and multimodal input could support contract analysis, research synthesis, and detailed content production. However, this variant has no supplied benchmark results, so its reasoning, coding, and agentic performance cannot be verified against the current field. The pricing is also substantially higher than GPT-5.4, especially for output.
Adopt it only for high-value workflows where the additional context or premium positioning is useful. GPT-5.4 is the safer default until comparable measured data is available.
