Overview

Freshness note: Model capabilities, limits, and pricing can change quickly. This profile is a point-in-time snapshot last verified on March 27, 2026.

GPT-5.2-Pro is still a current OpenAI API model. OpenAI’s current docs describe it as the version of GPT-5.2 that produces smarter and more precise responses, which makes it the premium compute-heavy option inside the GPT-5.2 branch even though GPT-5.4-Pro is the newer frontier-tier sibling elsewhere in the lineup.

Capabilities

GPT-5.2-Pro is suited for complex analytical tasks, difficult engineering problem-solving, and high-stakes decision-support workflows where deeper reasoning and output quality matter more than latency or throughput economics.

Technical Details

OpenAI’s current model card lists GPT-5.2-Pro with a 400K context window, 128K max output, image input support, and Responses API availability. It is designed as the top-quality tier in the GPT-5.2 line rather than a cost-optimized variant.

Pricing & Access

Published API pricing (per 1M tokens):

  • Input: $21.00
  • Output: $168.00

OpenAI does not list cached input pricing for this tier. This price band makes GPT-5.2-Pro best reserved for selective routing on high-value tasks.

Best Use Cases

Use GPT-5.2-Pro selectively for decision-ready memos, difficult engineering reviews, regulated analysis with strong human oversight, and escalation-stage agent tasks where better first-pass quality can pay for itself.

Comparisons

  • GPT-5.4-Pro (OpenAI): Better choice when you want OpenAI’s newest premium frontier route.
  • GPT-5.2 (OpenAI): Better default unless the extra precision is worth a large premium.
  • Claude Opus 4.6 (Anthropic): Contemporary premium alternative for high-quality reasoning work.
