OpenAI: GPT-5.4
Analysis Summary
GPT-5.4 is OpenAI's flagship general model in this batch, combining world-class reasoning with excellent coding and strong tool-connected performance. Its 1.05M token context can hold large document collections and codebases, while vision and file input support richer client workflows. Function calling makes it practical for structured integrations and agent applications.
The model suits software engineering, autonomous research, long-document analysis, strategic SEO, and customer-facing content where accuracy and instruction following matter. Its broad modality and technical capability allow one deployment to cover several agency tasks, reducing the need to split complex workflows across specialist models.
Listed pricing is higher than budget alternatives, especially for output, so it should handle high-value work rather than unrestricted volume. Adopt it as a primary choice for demanding workflows and route routine calls to a cheaper tier.
