Three unannounced OpenAI "aurora" models appear in API
Model IDs for aurora-red-alpha, aurora-green-alpha and aurora-blue-alpha showed up on 18 October, with no documentation from OpenAI.
The answer
Three undocumented OpenAI model IDs named "aurora" briefly appeared in the company's API on 18 October.
What happened: Three undocumented model IDs named "aurora" briefly appeared in OpenAI's API on 18 October, according to Crypto Briefing.
The details: The IDs are aurora-red-alpha, aurora-green-alpha and aurora-blue-alpha. Each carries an "alpha" tag.
The numbers: Responses differed by variant. Calls to aurora-red-alpha returned 503 capacity errors. The green and blue variants returned 404s.
The catch: OpenAI has published no changelog, pricing or use case for any of the three. It has not said what the models are.
Why it matters: A 503 capacity error suggests something sits behind the red ID, while the 404s on green and blue point the other way. Neither response confirms what the models are.
The context: The details here come from a secondary summary of the Crypto Briefing report. The full article was not reviewed.
What's next: OpenAI has not confirmed what the models are or whether it will release them. Watch the company's changelog for any announcement.
