GPT-5.2 Pro

GPT-5.2 Pro is OpenAI's frontier-grade model with adaptive reasoning and a 400k token context window.

Strengths

The model allocates computation dynamically based on task complexity, enabling it to handle both simple queries and complex multi-step reasoning efficiently.

Best for

General-purpose tasks requiring reasoning, long-form understanding, and nuanced instruction adherence across diverse domains.

Limitations

For specialized domains like coding or multimodal inputs, GPT-5.2-Codex, GPT Audio, or task-specific variants in the GPT-5.2 lineup may be better suited; this is the general-purpose tier.
