Current status · August 5, 2026
Quick answer: GPT-5.1 and GPT-5.2 are historical ChatGPT models, not the current default. OpenAI retired GPT-5.1 from ChatGPT on March 11, 2026 and GPT-5.2 on June 12, 2026. ChatGPT now uses GPT-5.5 Instant as its default, while the OpenAI API’s current frontier is GPT-5.6 Sol.
GPT-5.1 retired March 11; GPT-5.2 retired June 12. Existing GPT-5.2 conversations moved to corresponding GPT-5.5 models. See the official release notes.
The base GPT-5.1 and GPT-5.2 model pages remain live. The deprecated gpt-5.2-chat-latest snapshot is scheduled to shut down August 10, 2026, with GPT-5.6 Sol as the replacement. See deprecations.
GlobalGPT still lists GPT-5.1 and GPT-5.2 for legacy comparison, while its current flagship route is GPT-5.6 Sol.
As of August 5, 2026, GPT-5.2 and GPT-5.1 are legacy choices in ChatGPT, but both base models still have live OpenAI API pages. GPT-5.2 remains the stronger historical model for professional work, coding, long-context analysis, tool use, and multimodal reasoning; GPT-5.1 remains the warmer, lower-cost legacy option. For new frontier API work, OpenAI now recommends GPT-5.6 Sol, with GPT-5.6 Terra and Luna covering lower-cost workloads.
This article delivers the complete side-by-side analysis online. By the end, you will know exactly which model is best for your use case — and how to access both affordably.

Legacy Comparison Notes from July 2026
The following statements preserve the earlier decision context as a historical snapshot. They are not the current August 2026 access recommendation.
No. GPT-5.2 launched on December 11, 2025, but OpenAI released GPT-5.5 on April 23, 2026 and previewed GPT-5.6 Sol on June 26, 2026. GPT-5.2 is still important for comparison and migration decisions, but it should not be described as OpenAI’s newest or most advanced model as of July 2026.
July 2026 status note
Yes, for most technical and professional workloads. OpenAI’s GPT-5.2 launch benchmarks showed stronger results than GPT-5.1 Thinking on knowledge-work tasks, coding, long-context retrieval, factuality, tool use, vision, and abstract reasoning. GPT-5.1 may still feel better for simple everyday chat because GPT-5.1 emphasized warmer conversation and easier customization.
Legacy capability conclusion
Upgrade to GPT-5.2 if you work with long documents, codebases, spreadsheets, presentations, agent workflows, complex research, or multimodal inputs. Stay with GPT-5.1 if your main use cases are casual conversation, brainstorming, short writing, or lightweight Q&A and cost or speed matters more than frontier capability.
Legacy upgrade guidance
OpenAI described GPT-5.2 in ChatGPT as Instant, Thinking, and Pro. In the API, OpenAI listed GPT-5.2 Thinking as
Launch-era variant mapgpt-5.2, GPT-5.2 Instant asgpt-5.2-chat-latest, and GPT-5.2 Pro asgpt-5.2-pro.
Availability depends on whether you mean ChatGPT or the API. At the GPT-5.2 launch, OpenAI said GPT-5.1 would remain available to paid ChatGPT users for three months under legacy models, while also saying it had no current plans at that time to deprecate GPT-5.1 in the API. For current access, users should check OpenAI’s model and release pages because ChatGPT and API availability can change over time.
Launch-era availability note
No, not in OpenAI’s official API pricing at launch. OpenAI listed GPT-5.2 at a higher per-token API price than GPT-5.1 because it was more capable, while noting that better token efficiency could reduce the cost of reaching a desired quality level in some workflows. Third-party platforms may offer separate bundled or discounted access, but those offers are not the same as OpenAI’s official API pricing.
Legacy pricing conclusion
For new production workflows in July 2026, GPT-5.5 should be considered before GPT-5.2 if you need OpenAI’s stronger current capabilities. GPT-5.2 still makes sense for compatibility, budget planning, migration comparisons, or workflows already tuned around GPT-5.2 behavior.
