GPT-6 Sol leaks, screenshots and release rumors

The same prompt runs a shooting range scene at max, xhigh and high effort, using about 50k/30k/18k tokens and 6/3/2 minutes respectively, all zero-shot.

A Japanese user says a model's Japanese reads naturally with very little GPT flavor, and hopes GPT-6 Sol keeps that style.

A Japanese post claims OpenAI is internally testing GPT-6 Sol, a fast, high-performing model slightly behind Astra and aimed at Plus users, possibly launching at the Sept 29 DevDay.

The poster argues the model in ChatGPT clearly isn't like 5.6 Sol and may be GPT-6 Sol, a scaled-down version of the Astra breakthrough.

A leak says OpenAI is internally testing GPT-6 Sol, which is fast and solid but below Astra, may launch at the Sept 29 DevDay, and should have better usage limits than Astra.

A leak describes Sol as fast with strong reasoning and higher usage limits for everyday power users, and flags September 29 as a date to watch.

A Japanese user says GPT-6 Sol, Terra and Luna will all be released and hopes the lower-tier models also get Astra-level vision capabilities.

A user replying in a discussion says GPT-6 Sol will likely offer the same intelligence but be cheaper and faster.

A $200 Pro subscriber says Astra drains their usage quickly even on medium, and recalls running 5.6 Sol on Max all week with usage to spare.

A commenter says Astra would have been impressive if released as GPT-6 Sol, but struggles to see how a noticeably weaker Sol could still outperform GPT-5.6 Sol.

If Astra on low reasoning already beats Sol on high, one user wonders whether GPT-6 Sol will become the faster, cheaper daily model that still far outpaces the previous generation.

A developer's list of expected September 29 DevDay announcements includes the GPT-6 family with Sol, Terra and Luna, plus Astra Aeon and GPT-Image-2.5.
