- A tracker notes an Aurora-Alpha appeared on OpenRouter back on Feb 9 — though not from OpenAI.
- A separate tracker polling OpenAI's /v1/models endpoint spotted aurora-blue-alpha, -green-alpha and -red-alpha added on Oct. 18, following the Oct. 15 gpt-6-astra-api-priv-ev3 sighting, which reportedly included more than a model-list entry.
- The author claims these checkpoints are what OpenAI plans to release in response to Fable 5.5. Unconfirmed leak.
