New model slugs gpt-6-astra and gpt-6-astra-aeon appeared 30 minutes ago in a Statsig feature flag inside OpenAI's Codex Desktop, hinting at a GPT-6 series in the works. The poster credits @synthwavedd for the original find and notes "aeon" means "an immeasurably long period of time." Unconfirmed leak—OpenAI has not said anything official.
