GPT-6 Sol leaks, screenshots and release rumors

Cointelegraph reports that OpenAI released GPT-6 Sol and GPT-6 Luna with API prices 50% lower than its GPT-5.6 models.

A Chinese user sums up the release pace: Anthropic went first with Opus 5.5, OpenAI followed with GPT-6 Sol and Luna, and token prices fell 50%, with screenshots attached.

The AI/ML API team compared Opus 5.5 and GPT-6 Sol on four one-shot 3D scene prompts: Opus 5.5 produced more detailed renders at $4.37 total, while Sol cost $0.34.

A developer says September has been a busy month for commits, credits Opus 5.5 and GPT-6 Sol for the speedup, and urges others to raise their output expectations.

A comparison video with a Japanese title puts GPT-6 Sol and Opus 5.5 against each other on the same task.

The post ranks Claude Opus 5.5 above GPT 6 Astra, Fable 5.1 and GPT 6 Sol, putting Sol at the bottom.

The author added GPT-6 Sol, Luna and Claude Opus 5.5 to a same-prompt landing page comparison site and calls Opus 5.5 the strongest.

The poster says GPT-6 has 15 model variants and suggests switching among Astra/max, Sol/xhigh and Luna/max, noting a step down can stretch the weekly quota to seven days.

A Japanese-language AI model tier chart places the three newly released models in a single ranking, and the author says no objections will be accepted.

Vercel's Rauch shared fresh Next.js evals where Opus 5.5, GPT-6 Sol and Fable 5.1 all score 97%, while Grok 4.7 scores 94% at 2x to 7x lower cost.

The third-party platform says Sol and Luna are now live, with Luna available on all plans and Sol limited to Pro, Max and API.

The author had Opus 5.5 swap GPT-5.6 in the original image for GPT-6 series figures, producing a chart comparing Sol and Luna cost-performance with Opus 5.5's performance.
