GPT-6 Sol leaks, screenshots and release rumors

The post places GPT-6 Astra in the same role as Claude's Fable, expects Sol, Terra and Luna to follow, and suggests using Astra only for orchestration while assigning actual tasks to each model by difficulty.

The post maps the GPT-6 lineup against Claude 5.1, saying Sol through Luna could launch within a month, possibly at DevDay later this month.

A leak claims Sol is a faster GPT-6 variant that falls short of Astra's raw capability but offers better everyday usability and looser usage limits, possibly arriving at DevDay.

LuminaBench says Astra is a major leap as an agent orchestrator and hopes its token efficiency carries over to updated Sol, Terra and Luna versions.

A Japanese user relays rumors of follow-up models like Sol, Terra and Luna, and complains that Astra is unsuited to everyday conversation.

The author says daily work still pairs Sol/Opus with Luna/Sonnet, so they are more excited about the upcoming Grok 4.7 and the rumored GPT-6 Sol.

A post predicts that OpenAI's September 29 DevDay will bring GPT-6 Luna, Terra and Sol plus GPT-Image-2.5, and says Astra pulled some plans forward by six months.

A post claims that GPT-6 Sol entered internal testing just two days after GPT-6 Astra was released, with an image offered as evidence.

A Japanese account lists large AI models expected in mid-September or soon after, including Grok 4.7, GPT-6 Sol, Gemini 4 and Claude Fable 5.2.

A user says GPT-6 Astra is already a beast and they can't imagine what GPT-6 Sol will be like, joking that Fable 5.1 will be completely overshadowed.

Account koltregaskes speculates that GPT-6 Sol is the next release and expects it within the next few weeks, with no screenshot evidence.

A user says GPT-6 Sol rumors are already circulating but they would rather have Luna 6, expecting it to cost about 80% less and to be enough for most work, and wants to pair it with an ideal version of Grok 4.7.
