GPT-6 Sol leaks, screenshots and release rumors

The poster says that if Sonnet 5.5 beats GPT-6 Sol, they will move fully to Claude unless OpenAI offers a cheaper, more pleasant model.

The post shares a Claude Code self-check prompt for the Sonnet 5.5 gray test and says Sonnet 5.5 is priced in the same tier as GPT-6 Sol but faster.

A leak says Sonnet 5.5 launches next week, is cheap and strong, and could be an efficient alternative to GPT-6 Sol much as Opus 5.5 was; Minimax-M3.1 is also mentioned.

The update switches Devin from devin acp to Devin's own API, reusing CLI login with no extra setup, and has been tested with Claude Code and OpenCode on Opus 5.5, SWE-2 and GPT-6 Sol for multi-turn file reads and writes.

A leak claims Sonnet 5.5 is in grey testing in Claude Code with some accounts already routed to it, beats GPT-6 Sol in most areas, keeps Sonnet 5 pricing, and may launch around OpenAI DevDay.

A user says GPT-6 Sol feels dumb next to GPT-5.6 Sol, overthinking, ignoring instructions and needing more babysitting, and has switched back to 5.6.

A recap video rounds up a week of model and product releases, including GPT-6 Sol, Luna, Opus 5.5, Grok 4.7 and others.

A Chinese satirical post invents a CEO dialogue in which Altman says gpt-6-sol is just a small model sold at a discount, while Dario claims opus-5.5 crushes everything.

A long post argues multi-turn agents destabilize after turn 20 and need routing separated from generation, assigning GPT-6 Sol to parallel extraction and Luna to verification while claiming 12.8x speed and 116x lower inference cost.

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 Turkish user says the cheap accounts they bought do half-baked, error-prone work that only becomes usable after GPT-6 Sol corrections, and complains its image generation is now worse than Gemini's.
