ChatGPT 5.2

On December 11, 2025, OpenAI introduced GPT-5.2—the most advanced model for professional work. The model shows results above expert level on real tasks spanning 44 professions. Average ChatGPT Enterprise user saves 40-60 minutes daily, while active users save over 10 hours weekly.

GPT-5.2 sets new records: 70.9% wins over professionals on GDPval, 55.6% on SWE-Bench Pro, 100% on AIME 2025, 90.5% on ARC-AGI-1. Three model versions available: Instant for fast work, Thinking for complex tasks, Pro for maximum quality.

In this guide we'll break down GPT-5.2's key capabilities, results on professional tasks, programming improvements and how the model changes approach to AI work.

What Is GPT-5.2 from OpenAI

GPT-5.2 is OpenAI's most advanced model series for professional knowledge work. The model designed for creating spreadsheets, presentations, writing code, analyzing images, understanding long contexts and handling complex multi-step projects. This is OpenAI's first model working at or above human expert level.

GPT-5.2 Thinking wins or ties with top professionals in 70.9% of comparisons on GDPval tasks as judged by expert evaluators. The model produces results more than 11 times faster and at less than 1% cost of experts. Companies Notion, Box, Shopify, Harvey and Zoom noted leading performance in long-form reasoning.

Three GPT-5.2 Versions:

  • Instant — fast model for daily work with improved conversational tone

  • Thinking — for deep work on complex tasks with detailed reasoning

  • Pro — smartest option for mission-critical tasks where maximum quality matters

Key GPT-5.2 Improvements

GPT-5.2 brings significant improvements in general intelligence, long-context understanding, agentic tool calling and vision. Model better executes complex real-world tasks from start to finish than any previous model.

Main Improvements:

  • Professional tasks: 70.9% wins over experts on GDPval (44 professions)

  • Programming: 55.6% on SWE-Bench Pro, 80% on SWE-bench Verified

  • Mathematics: 100% on AIME 2025, 40.3% on FrontierMath Tier 1-3

  • Vision: errors cut in half on charts and interfaces

  • Hallucinations: 30% fewer errors (6.2% vs 8.8% for GPT-5.1)

  • Abstract reasoning: 90.5% on ARC-AGI-1, 54.2% on ARC-AGI-2

Databricks, Hex and Triple Whale found model exceptional for agentic data science and document analysis. Cognition, Warp, Charlie Labs, JetBrains and Augment Code report leading coding performance with measurable improvements in interactive programming, code review and bug finding.

Results on Professional Tasks — GDPval

GPT-5.2 sets new record on GDPval—evaluation measuring well-defined knowledge work tasks across 44 professions from top-9 US industries. Tasks request real work products: sales presentations, accounting spreadsheets, emergency care charts, manufacturing diagrams, short videos.

GPT-5.2 Thinking wins or ties with top professionals in 70.9% of comparisons. One GDPval judge commented: "Exciting and noticeable jump in quality... looks like it's done by professional company with staff, has surprisingly well-developed layout."

GDPval Results (wins or ties against professionals):

  • GPT-5.2 Pro: 74.1% — new maximum

  • GPT-5.2 Thinking: 70.9% — first model at expert level

  • GPT-5 Thinking: 38.8% — previous generation

On internal test of junior investment banking analyst spreadsheet modeling tasks, GPT-5.2 Thinking average score grew 9.3%: from 59.1% to 68.4%. Tasks include creating three-statement models for Fortune 500 companies with proper formatting and citations, or building leveraged buyout model for privatization.

Programming — 55.6% on SWE-Bench Pro

GPT-5.2 Thinking sets new record of 55.6% on SWE-Bench Pro—rigorous real-world software engineering evaluation. Unlike SWE-bench Verified (Python only), SWE-Bench Pro tests four languages and is more resistant to contamination, harder, more diverse and industrially relevant.
