What is GPT-5.4 used for?

GPT-5.4 is designed for complex professional work including large codebase analysis, extensive legal and financial document review, scientific literature synthesis, and multi-step reasoning tasks. Its 1 million token context window is the key differentiator for enterprise use cases.

How much does GPT-5.4 cost?

OpenAI uses tiered pricing: standard context (under 128K tokens) at regular token rates, with a 2-3x premium for long context (128K-1M tokens). Enterprise access via Microsoft Azure AI Foundry; consumer access through ChatGPT Plus/Pro subscriptions.

How does GPT-5.4 compare to Claude 3.7 and Gemini 2.5 Pro?

All three are top-tier frontier models. GPT-5.4 leads on user base and ecosystem integration (Microsoft). Claude 3.7 is often rated slightly ahead on coding and long-document analysis. Gemini 2.5 Pro has comparable context windows and more aggressive pricing for long-context use cases.
