Rumors Swirl Around OpenAI's Next-Gen Model Codenamed Astra
Starting August 18, multiple independent sources leaked details about OpenAI's next-generation model codenamed Astra, rumored to launch this week (possibly Thursday). It is described as the next major model after GPT-4, potentially named GPT-5.7 or GPT-6, with major leaps in math and autonomous agent capabilities—some even calling it AGI-level. None of this is officially confirmed, and Polymarket prices only a 47% chance of release by end of next month.
Confirmed
- @WorldofAI's roundup: Astra may focus on long-horizon multi-agent systems working with Codex; a hidden GPT-5.6 Sol with 1 million token context was found in Codex
- @markk relays rumors that Astra focuses on Agent Swarms with strong math capabilities, possibly named GPT-6
- @imjustnewatai reports the internal Astra produced ten major results in math and theoretical computer science for roughly $2,000 in compute, solving multiple long-standing problems; six days later OpenAI assessed its agentic coding and cyber capabilities as strong enough that critical human-free capabilities cannot be ruled out
- @VraserX says Astra is expected Thursday at AGI level; a follow-up compilation says OpenAI calls it the "next major model," possibly GPT-5.7 or GPT-6, potentially succeeding ChatGPT and Codex
- @新智元 adds the leaks claim the $2,000 run solved 10 problems open for over a decade, spanning high-dimensional geometry and lattice cryptography, and that the model poses extreme cybersecurity risks
- @haider1 (repost): a leaker says OpenAI's next 6 weeks are packed, targeting "AI research intern" level next month; the blogger speculates a Dev Day demo on September 29
- @AccBalanced (repost): tweet analysis notes OpenAI has been testing an undisclosed internal model since at least early May, while Astra's designation for cyber "critical" security came less than two weeks ago, implying testing around July-August—possibly a different model
- @Polymarket shows markets pricing a 47% probability that OpenAI releases Astra by end of next month, with rules requiring official confirmation and public availability (including beta)
Unconfirmed
- Timing (this week vs Thursday vs Dev Day) varies across sources with no official confirmation
- The official name (GPT-6, GPT-5.7, or other) and "AGI-level" claims remain rumors
- Whether the undisclosed model tested since May is the same as Astra rests only on timeline inference
Why it matters
- If true, Astra's leaps in math and autonomous agents could reshape AI coding and research automation; the extreme cybersecurity risk and the "no human intervention" assessment flagged by @新智元 warrant serious attention
- If the timeline analysis holds, OpenAI may be testing more than one undisclosed new model, making the picture more complex than a single "Astra" rumor
- Polymarket's mere 47% probability shows markets are far from convinced, so official moves should be tracked closely
