Two new model names — gpt-6-astra and gpt-6-astra-aeon — have appeared in Codex, suggesting an OpenAI launch under the Astra codename is imminent. Commenters speculate that Aeon could be a long-horizon variant built to keep agents working for days, which would be a major jump. Unverified, but consistent with recent Astra rumors.
