GPT-6 Sol leaks, screenshots and release rumors

A roundup post lists more than a dozen models released in September, including GPT-6 Astra, GPT-6 Sol and GPT-6 Luna.

Merge Gateway says GPT-6 Sol and Luna are now callable at half the price of the 5.6 series, with Sol making about half as many mistakes as GPT-5.6 Sol.

A reply maps Anthropic and OpenAI unreleased models by tier and says Opus medium costs little more than GPT-6 Sol max.

Design Arena now hosts GPT-6 Sol and Luna, which it says build on the advances behind Astra and are stronger and cheaper at professional work, factuality, coding and computer use.

Both frontier models launched the same day, and given the same prompt to animate a looping 3D pelican on a bicycle in Blender, one user says Opus 5.5 produced the more charming result.

A short Japanese post mentions GPT-6 Sol and Luna and asks whether Terra was laid off as rumored.

A reminder that Codex users received one banked reset with the GPT-6 Sol and Luna launch, with the expectation that quotas will run out again soon.

A short post argues that the GPT-6 Sol and Luna naming skips a version, and they are really more like GPT-5.7.

He says Sol is clearly stronger than GPT 5.6, but still ranks Opus 5.5 above Fable and Astra as the best model available right now.

After testing, a user says Opus 5.5 performs far better than GPT-6 Sol and Luna, with pricing as its only weakness, and calls it the best model output they have seen.

A Polish post says GPT-6 Sol and Luna arrived shortly after Claude, with API pricing half that of GPT-5.6, and the author is pleased.

A self-described OpenAI fan says Opus 5.5 medium costs about the same as GPT-6 Sol but is better at almost everything.
