Current status \u00b7 August 5, 2026<\/p>\n

Quick answer:<\/strong> 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\u2019s current frontier is GPT-5.6 Sol<\/strong><\/a>.<\/p>\n

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<\/a>.<\/p><\/div>\n

OpenAI API<\/strong>

The base GPT-5.1 and GPT-5.2 model pages remain live. The deprecated gpt-5.2-chat-latest<\/code> snapshot is scheduled to shut down August 10, 2026, with GPT-5.6 Sol as the replacement. See deprecations<\/a>.<\/p><\/div>\n

GlobalGPT<\/strong>

GlobalGPT still lists GPT-5.1 and GPT-5.2 for legacy comparison, while its current flagship route is GPT-5.6 Sol<\/strong><\/a>.<\/p><\/div>\n <\/div>\n<\/section>\n\n\n\n

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<\/strong><\/a>, with GPT-5.6 Terra and Luna covering lower-cost workloads.<\/p>\n\n\n\n

This article delivers the complete side-by-side analysis online. <\/strong>By the end, you will know exactly which model is best for your use case<\/strong> \u2014 and how to access both affordably.<\/p>\n\n\n\n

GlobalGPT has fully integrated GPT-5.6 Sol<\/strong><\/a>, GPT-5.5, GPT-5.2, GPT-5.1, and other models. As of August 5, 2026, its Basic plan is listed at $11.9 month to month<\/strong> or $5.8 per month with annual billing<\/strong>.<\/p>\n\n\n\n
