It seems like every week there is a new model. I was just creating a new chat in ChatGPT and I saw it change to 5.2. So I don't know how it is yet. but here is the overview and the full blog post below. Let us know if you find it useful for certain tasks ! ## Introducing GPT-5.2 — Key Takeaways for Builders & Professionals **GPT-5.2** is OpenAI’s most advanced frontier model to date, built for professional knowledge work and long-running, agentic workflows. It delivers major gains in quality, reliability, and real-world usefulness across coding, analysis, documents, vision, and tool use. ### Why it matters - **Real economic impact:** GPT-5.2 Thinking matches or exceeds human experts on **70.9% of GDPval tasks** across 44 occupations, producing work faster and at a fraction of the cost with human oversight. - **Built for end-to-end work:** Stronger long-context reasoning, tool calling, and planning make it better at completing full workflows, not just single answers. ### Major improvements - **Knowledge work:** Higher-quality spreadsheets, presentations, reports, and planning artifacts with better structure and formatting. - **Coding:** New state of the art on SWE-Bench Pro (55.6%) and Verified (80%), with major gains in debugging, refactoring, front-end, and agentic coding. - **Long context:** Near-perfect accuracy on long-document reasoning (up to 256k tokens), enabling deep analysis of large reports, contracts, and multi-file projects. - **Vision:** Roughly half the error rate of prior models on charts, dashboards, and UI screenshots; better spatial understanding of images. - **Factuality:** ~30% fewer response-level errors than GPT-5.1 Thinking, making it more dependable for research and decision support. - **Science & math:** State-of-the-art results on GPQA, FrontierMath, ARC-AGI-1 and ARC-AGI-2, with early evidence of real research acceleration. ### Models & use cases - **GPT-5.2 Instant:** Fast, everyday workhorse for info-seeking, writing, and learning.
