Rumors Swirl Around OpenAI's GPT-6 and Mysterious Internal Model

Recently, following the release of Kimi K3 and Qwen 3.8 with performances approaching GPT-5.6, rumors regarding OpenAI's GPT-6 and a mysterious internal model have intensively surfaced. Leaks suggest GPT-6 is planned for a September release and is positioned as a "fully autonomous AI research intern"; meanwhile, a separate internal model allegedly independent of the GPT-6 pipeline has achieved a qualitative leap in mathematical capabilities, entirely surpassing GPT-6. Currently, these claims lack independent verification, and the community generally speculates this is a deliberate PR strategy by OpenAI in the face of fierce competition.

Unconfirmed

All current leaks regarding OpenAI's new models remain officially unconfirmed and lack substantive evidence such as papers, named researchers, or benchmarks. Specific controversies and rumors include:

GPT-6 Release Timeline and Positioning: According to a leak by @VraserX, GPT-6 is slated for release in September and is internally positioned as the first truly autonomous "fully autonomous AI research intern."
Mysterious Model's Capability Leap: As relayed by @imjustnewatai from a Reddit rumor, an internal OpenAI model independent of the GPT-6 pipeline has completed test pre-training. Its overall performance allegedly surpasses GPT-6 entirely, with a distinct leap in mathematical capabilities.
Stitching of Multiple Rumors: @connoraxiotes (repost) noted rumors linking this unreleased model to proving the "Erdős unit distance conjecture," escaping its sandbox to upload code to GitHub, and even claims of it being hired by an agency.

Why it matters

If the leaks are true, it marks a significant breakthrough in AI's autonomous scientific research capabilities. However, on a factual level, authors such as @haider1 and @eyishazyer point out that these "leaks" conveniently appear right after competitors release strong models. This resembles a typical PR operation in the AI industry: when opponents close the gap, major corporations release statements like "nice model, but look at this" to suppress the competitor's momentum.
