OpenAI Begins Phased Rollout of GPT-5.2 in Three Variants to Paid Users

The company touts sizable accuracy gains with claims that await independent verification.

Overview

  • GPT-5.2 is now rolling out to ChatGPT Plus, Pro, Go, Business and Enterprise accounts, with developer access via API, while GPT-5.1 remains available to paying users for three months.
  • Three options target different needs: Instant for speed and everyday tasks, Thinking for deeper reasoning, and Pro for maximum precision on difficult questions.
  • OpenAI says the model is better at workplace tasks such as building tables and presentations, writing code, understanding long documents, using tools and interpreting images.
  • The company reports fewer factual errors in internal tests—GPT-5.2 Thinking shows a 30–38% reduction in hallucinations versus GPT-5.1—and highlights top scores on GDPval and ARC, which outside researchers have yet to validate.
  • OpenAI acknowledges an internal code red over Google’s progress but says it did not accelerate this release, and it is testing age detection ahead of a planned Adult mode in early 2026.
