OpenAI Tests Multi-Agent Model Astra, Demoed to US Officials

According to The Information, OpenAI is testing a new model family codenamed Astra, focused on multi-agent long-horizon collaboration. CEO Sam Altman has privately demoed it to US policymakers in Washington this week. Astra can decompose complex projects (e.g., advanced math research, quantum complexity, theoretical computer science) into multiple agents working in parallel over extended periods, marking a shift in OpenAI's R&D focus toward multi-agent coordination. The series is expected to sit alongside Sol, Terra, and Luna, with final naming possibly GPT-6 or GPT-5.7.

Confirmed

• Model positioning: Astra is described as a multi-agent system, with core capability of coordinating multiple agents over long durations to solve long-horizon complex tasks. According to @danielmac8, it has solved 10 hard problems spanning math, quantum complexity, and theoretical computer science.
• Product line: Within OpenAI's internal product line, Astra will sit alongside Sol, Terra, and Luna. Additionally, per @新智元, OpenAI recently announced over 1 billion global active users, driven by significant price cuts (GPT-5.6 Luna down 80%, Terra down 20%).
• Policy engagement: Sam Altman has shown the system to US government officials, and Astra is expected to be among the first AI models to undergo US government safety review.
• Release expectation: Prediction market Polymarket shows a 56% probability of public release by the end of next month.
• Cost and evaluation: Per @danielmac8, solving these 10 math problems with Astra would cost up to $2000 based on GPT-5.6 Sol API pricing. OpenAI researcher Noam Brown called it a major advance in scientific reasoning.

Unconfirmed

• Final naming: Leaks suggest the series may be released as GPT-6 or GPT-5.7; specific product form and final version number are undetermined.
• Performance: Tech blogger @VraserX predicts Astra will likely saturate the ARC-AGI-3 benchmark due to its long-horizon reasoning and persistence on hard problems, but this is his personal speculation.

Why it matters

The exposure of Astra indicates OpenAI's R&D focus is shifting toward multi-agent long-horizon collaboration, seen as a key technical path to tackle complex problems. Simultaneously, the demo to policymakers reflects OpenAI's proactive engagement with government oversight and safety evaluation for frontier models.
