The most advanced frontier model for professional work and long-running agents.
GPT-5.2 brings stronger performance on complex, multi-step tasks. It is better at building spreadsheets and presentations, writing code, interpreting images, and working with long contexts.
Agentic coding takes a major step forward, making GPT-5.2 the leading model in its price range and the new default for tools like Windsurf.
The Thinking variant is more reliable, with about 30 percent fewer factual errors. It hallucinates less, which makes it more dependable for research and analysis.
Long-context reasoning reaches a new high. GPT-5.2 nearly solves the 4-needle MRCR benchmark and clearly outperforms GPT-5.1 when analyzing very long documents.
There is no API facility for informing the AI what you want to receive nor any events for other than image tool use. So it cannot output images.
While it was indicated that the gpt-5.1 model can generate images in one AMA response … so can gpt-4o. That modality is not exposed except by a special trained model gpt-image-1 completely wrapped in tools and image endpoints and safety.
