GPT-6 Sol leaks, screenshots and release rumors

banteg says Opus 5.5 solved an 1,800-line player_update function, after over 100 agent-hours since July, including 50 hours from gpt-5.6-sol and 20 from gpt-6-astra.

A user says matching Opus performance with GPT-6 Sol Max consumes the entire 5-hour limit, while Opus 5.5 delivers better results using half of it.

The author argues GPT-6 Sol and Luna were modest upgrades but good value, until Opus 5.5 shipped the same day with a big jump and made Sol look worse than it actually was.

An internal writing benchmark found higher reasoning effort generally gives modest gains at about 2.5x the cost, and GPT-6 Sol at max beats Astra while cheaper and faster.

A weekly AI recap covers GPT-6 Sol and Luna launching the same day as Claude Opus 5.5, API pricing 50 percent below GPT-5.6 promo rates, plus OpenAI math claims, misalignment incidents and other news.

TokenGremlin argues Sol is essentially a heavily upgraded GPT-5.6 that picked up a few tricks from Astra, which explains why it loses to Opus 5.5 and Sonnet 5.5.

The author asked Claude Opus 5.5 and GPT-6 Sol to create the same glitter sticker effect and concludes Opus 5.5 is clearly stronger on this task, with a video comparison.

Comparing paper writing, review, search, readability and slide design, the author finds Opus text easier to read and GPT more rigorous, and decides to keep Pro Lite.

The author says Opus 5.5 lives up to its reputation with limits barely dropping and high EQ, while GPT-6 Sol is cheap but underpowered and takes over tasks previously handled by GPT-5.6 Luna, and questions whether OpenAI plans to offer the GPT-6 series in web ChatGPT.

A post says Opus 5.5 is remarkably fast and efficient, while GPT-6 Sol is a cost-saving model not meant to compete at that level.

A demo video shows a 3D scene made with GPT-6 Sol and Opus 5.5 together with Unreal and Blender.

A long video post describes a system using Jev for routing and Opus 5.5 with GPT-6 Sol/Luna for divided tasks, claiming a 116x cut in inference cost.
