- Designed to unlock economic value in real-world workflows (e.g., spreadsheets, reports, presentations)
What’s New in GPT-5.2?
According to OpenAI’s official release, GPT-5.2 is designed for higher productivity, deeper reasoning, and more reliable workflows, including:
- Improved reasoning with new internal thinking tokens
- Stronger multimodal performance (images, charts, diagrams)
- Better long-context understanding (documents, books, PDFs)
- Higher accuracy and fewer hallucinations
- A new GPT-5.2 Pro variant for advanced professional workloads
OpenAI notes that GPT-5.2 is built to unlock “real economic value” across tasks like research, spreadsheets, analysis, and technical writing.

2. Reasoning & Intelligence Benchmarks
GLBGPT benchmark data shows a dramatic performance jump:
2.1 General Knowledge Work (GDPval Benchmark)
| Model | Score |
| GPT-5.1 Thinking | 38.80% |
| GPT-5.2 Thinking | 70.90% |
| GPT-5.2 Pro | 74.10% |
GPT-5.2 nearly doubles GPT-5.1’s performance on real knowledge-work tasks such as:
- Research synthesis
- Spreadsheet reasoning
- Document analysis
- Technical content generation
2.2 Abstract Reasoning
This is a 3× improvement, showing how much deeper GPT-5.2 can reason.
3. Coding, Debugging & Software Engineering
GPT-5.2, especially Pro, excels at:
- Multi-file refactoring
- Large repository understanding
- Automated debugging
- Architectural design
- System-level reasoning
GPT-5.1 was already strong, but GPT-5.2 is a clear upgrade for:
Developers
- better code correctness
- fewer hallucinations
- more consistent debugging
- clearer explanations
Engineering teams
- superior documentation generation
- end-to-end workflow execution
- improved reliability in complex tasks
Developers benefit from a 55.6% success rate on SWE-bench Pro (a harder version of the standard benchmark), significantly outperforming GPT-5.1’s 50.8%, which reduces the engineering time needed for debugging and refactoring.
4. Multimodal Intelligence (Vision + Text)
GPT-5.2 significantly improves:
- Chart interpretation
- Diagram reasoning
- Screenshot understanding
- Layout analysis
- Mathematical visual reasoning
- OCR stability
These gains make GPT-5.2 a strong choice for:
Researchers/ Students/ Analysts/ Product managers/ Data visualization work
5. Long-Context Performance
GPT-5.2 improves:
- Document memory
- Cross-page coherence
- Referencing across long texts
- “Whole-book” level tasks
GPT-5.1 could handle long context well, but GPT-5.2 handles it with far fewer errors.
6. Workflow Automation & Tool Use
GPT-5.2 is specifically engineered for:
- Chained tool calls
- Multi-step planning
- Autonomous agent workflows
- Data extraction + transformation
- Business process automation
GPT-5.1 performs simple tool calls well but cannot match GPT-5.2’s reliability in multi-stage reasoning and autonomous execution.
7. Behavior, Alignment & Hallucination Reduction
GPT-5.2 is:
- More accurate
- More aligned
- More consistent
- Less likely to hallucinate
