GPT-5.4

$60.00/1M out

Best for teams or workflows locked into the original gpt-4 api that require reliable, high-quality text reasoning without needing long context or multimodal input.

At $30/$60 per million tokens, this is one of the most expensive text-only models available. The 8,191-token context window is a hard ceiling that makes it unsuitable for most document-processing tasks. OpenAI continues to offer it for API backward compatibility but actively recommends migrating to GPT-4o or GPT-4 Turbo. New projects should not default to this model.

$60.00/1M out

Best for reproducible research or legacy workflows that require consistent, version-locked gpt-4 outputs.

This is a frozen March 2023 snapshot of GPT-4, not a current model. OpenAI may deprecate legacy snapshots with limited notice. The 8,191-token context window is a hard constraint. Cost is identical to much more capable current models, making this a poor choice for new projects.
