GPT-6 Sol leaks, screenshots and release rumors

The author fed a muted video to Codex (GPT-6 Astra/Sol) to design sound effects without a DAW or third-party samples, and shared a reusable prompt.

A Japanese post says Sol and Luna had a bug that degraded image understanding and that it has been fixed, noting Browse and Computer Use tasks were also affected, which may explain weaker benchmark results.

The official developer account says a bug degrading image understanding in GPT-6 Sol and Luna is fixed, and visual tasks in the API and Codex, including computer use, should now perform better.

The post claims Opus 5.5 launched the same day as GPT-6 Sol and Luna, and that a new Sonnet 5.5 checkpoint is reportedly set for next Tuesday, the same day as OpenAI DevDay, to steal attention.

The poster retracts their criticism of GPT-6 Sol, saying every GPT model except Astra has degraded, with Excel tasks that 5.6 Sol High once one-shotted now taking three or four iterations.

The author shows Codex (GPT-6 Sol) using tmux capture-pane to peek at Opus 5.5's progress and tmux send-keys to talk to it, and taking over unfinished work when Claude runs out of tokens.

A leaker speculates astra-minor is a distilled Astra that could fill the pricing gap between GPT-6 Sol ($2/$10) and Astra ($10/$50), competing with Opus 5.5 at $4/$20.

A post asks readers to pick one side for coding right now, Opus 5.5 or GPT-6 Sol, with no fence-sitting allowed.

A 19-year-old's first vibe-coding project uses Sol to write the app and jev for sub-second responses, with gesture control of a globe; he says four hotel lobbies have paid $11,600.

A developer says GPT-6 Sol makes frequent mistakes in domain modeling, data discovery and software architecture that GPT-5.6 Sol did not, citing the model's own line about starting at the top of the code listing.

The post says GPT-5.6 Sol ranks #19 on Text Arena while GPT-6 Sol drops to #60, calling it a regression for everyday conversation despite being cheaper and stronger at coding and agentic work.

A user who bought Codex Plus to compare GPT-6 Sol with Astra says the 5-hour limit ran out in 10–15 minutes without finishing one prompt, and threatens to cancel.
