GPT-5.2, OpenAI’s most sophisticated frontier AI model to date, is now available to ChatGPT users. The new ChatGPT 5.2 model is regarded as OpenAI’s direct response to Google’s Gemini 3 Pro after an internal “code red” scenario was declared. Three new AI models—GPT-5.2 Instant, GPT-5.2 Thinking, and GPT-5.2 Pro—are included in the latest ChatGPT 5.2 version.
What is New in ChatGPT 5.2?
OpenAI has officially launched GPT-5.2, its most advanced frontier AI model ever, and it is already available to ChatGPT users. After declaring a “code red” situation internally, the new ChatGPT 5.2 model is considered as OpenAI’s direct response to Google’s Gemini 3 Pro. The latest ChatGPT 5.2 release includes three new AI models: GPT-5.2 Instant, GPT-5.2 Thinking, and GPT-5.2 Pro.
In the SWE-Bench Pro benchmark which measures performance on software engineering tasks, GPT-5.2 Thinking achieved 55.6%, higher than Claude Opus 4.5 (52.0%) and Gemini 3 Pro (43.3%). Next, in SWE-bench Verified, GPT-5.2 Thinking got 80.0%, but Claude Opus 4.5 continued to maintain its supremacy with 80.9%.
In GPQA Diamond (a benchmark consisting science questions), GPT-5.2 Thinking achieved 92.4% without tool use, again beating Gemini 3 Pro. Notably, in ARC-AGI-2, GPT-5.2 Thinking scored 52.9%, much higher than Claude Opus 4.5 (37.6%) and Gemini 3 Pro (31.1%).
And on GDPval — a benchmark measuring well-specified knowledge work across 44 occupations — GPT-5.2 Thinking matches or performs better than top industry professionals on 70.9% of tasks.
ChatGPT 5.2 is rolling out today to paid users including Go, Plus, Pro, Business, and Enterprise. The knowledge cutoff date of GPT-5.2 is August 2025 which means it’s a fairly new AI model. Meanwhile, OpenAI also suggested that adult mode in ChatGPT is coming in the first quarter of 2026. OpenAI is testing an age prediction model for users under 18.
