GPT-6 Sol

Rumored and unverified

GPT-6 Sol is a rumor label tracked at the user's request, not an OpenAI-confirmed product name. As of September 11, 2026, OpenAI's public model directory lists GPT-5.6 Sol and the released GPT-6 Astra, but not GPT-6 Sol.

X lead and evidence boundary

This record began with a request to check an X rumor. The publicly accessible X search for GPT 6 Sol did not return an attributable, verifiable post at the time of review. It therefore supports no claim about an author, timing, features, or availability. Any future X post would still need confirmation from OpenAI documentation, an announcement, or a reproducible API response before it could establish a product fact.

Not GPT-5.6 Sol or GPT-6 Astra

GPT-5.6 Sol and GPT-6 Astra are separate public model names. Similar wording does not establish GPT-6 Sol or imply that it shares either model's API, context window, tools, reasoning settings, price, or evaluation results. This record intentionally does not copy fields from either model.

Unknown fields

OpenAI has not published a parameter count, architecture, context window, output limit, modalities, tools, reasoning modes, knowledge cutoff, API ID, availability, price, licence, or benchmark result for GPT-6 Sol. Those fields remain empty. The displayed date is the rumor-review date, not a release date or release prediction.
