GPT-6 Sol leaks, screenshots and release rumors

A Chinese user says Opus 5.5 is aimed at GPT-6 Astra while OpenAI is still releasing smaller Sol and Luna models, and calls for a GPT 7.

Higgsfield asked both models to design an accessible 3D-printable prosthetic hand and build a website with an interactive 3D model, CAD files and assembly instructions.

A Turkish blogger says OpenAI released GPT-6 Sol and Luna the same day, with Sol aimed at doing hard tasks faster and cheaper and Luna as a lighter everyday option.

A post says Opus 5.5, GPT-6 Sol and Luna 6 launched the same week, with Sol scoring 48 on AA at $2/$10, only slightly above 5.6 Sol but at half the price.

An attendee notes that Opus 5.5, GPT-6 Sol and Luna all arrived at once and plans to try them hands-on at a 2,000-person generative AI exhibition.

The author says that after using the latest models to code, market and ship 5 mobile apps, the ranking is Opus 5.5 first, GPT-6 Sol second and Grok 4.7 third.

A Japanese news flash reports that OpenAI released GPT-6 Sol and Luna, which keep Astra's strengths while being faster and cheaper, with API prices 50% below GPT-5.6's promotional price.

A hands-on test generated one humanoid character each with Opus 5.5 and GPT-6 Sol: Opus 5.5 handled fingers and hair more naturally, while Sol's design was cuter but its hairstyle still fell short.

The author maps models by price and capability: Opus 5.5 as the main pick, GPT-6 Sol for high-volume OpenAI work, Astra and Fable for the hardest problems, and lists each API's per-token price.

Simon Willison writes up the day's three model releases and includes comparison grids of pelicans generated by different model families at different reasoning levels.

A Chinese user says the newly released GPT-6 Sol and Luna are not a leap over the previous generation but a cheaper version of 5.6, citing official comparison data.

A claimed ex-Anthropic engineer's leak says Anthropic shrank its model while OpenAI cut prices, and cites data showing Sol regressed on coding and knowledge work.
