GPT-6 Sol leaks, screenshots and release rumors

Microsoft's Copilot blog says Claude Opus 5.5 and GPT-6 Sol are rolling out to Word, Excel, Chat, Cowork and Copilot Studio, with timing varying by region and license.

A short promotion recommends pairing ready-made Skills with GPT-6 Sol or Opus 5.5 to actually build your app.

A screenshot shows GPT-6 Sol appearing in Codex after an update, and the author says it reaches Fable 5.1-level scores at about a tenth of the cost and plans to make it their main tool.

The author compared Sol and Astra on a "robot drawing on the board" benchmark, finding Sol's controller drew twice as fast and cost nearly 5x less, though spatial reasoning fell short of expectations.

An $NBIS investor post jokes that Anthropic releasing Opus 5.5 and OpenAI releasing GPT-6 Sol and Luna stole the company's thunder just 10 days after it was "pacing the frontier."

A bedtime post says the author can't wait to try Opus 5.5, GPT-6 Sol and Luna tomorrow with a fresh brain and good coffee, with no substantive information.

An infographic explains that GPT-6's Astra, Sol and Luna target high performance, balance and lightweight use, and says Sol and Luna API prices dropped 50%.

Lech Mazur's Extended NYT Connections Benchmark shows Opus 5.5, GPT-6 Sol and Luna all slightly behind their predecessors but far cheaper, with data on GitHub.

A comparison video has each model build an interactive human-eye page that can be taken apart and inspected in 3D, showing differences in front-end and 3D ability.

The post claims Sol and Luna are out with higher usage limits and API prices half of GPT-5.6 promotional pricing, and includes screenshots; it is a launch-period rumor.

A Japanese video report says Sol beats Claude Opus 5 on OpenAI's business automation test, both models cut API prices about 50% versus GPT-5.6, and they are live in ChatGPT Work and Codex.

Higgsfield released a comparison video pitting the two models against each other on 3D game development in Unreal Engine to see which produces more complete output.
