OpenAI lists three aurora-alpha models in its API
OpenAI has added three new model identifiers—aurora‑red‑alpha, aurora‑green‑alpha and aurora‑blue‑alpha—to its developer interface, according to a post on X by AI researcher @scaling01 on October 18, 2026. The company has not issued any official announcement, documentation, pricing details or use‑case guidance for the models, and no changelog entry confirms their status.
Key points
- OpenAI’s API now shows aurora‑red‑alpha, aurora‑green‑alpha and aurora‑blue‑alpha identifiers.
- OpenAI has provided no official details on capabilities, pricing, or intended use cases.
- Speculation ties the aurora models to a GPT‑5.3‑Codex‑Spark lineage, but the link is unconfirmed.
The aurora name first appeared with a model called aurora‑alpha on OpenRouter in February 2026, which some observers have linked to a speculative GPT‑5.3‑Codex‑Spark variant. The recent X post suggests the red, green and blue versions might reflect newly optimized Codex features or faster inference, but OpenAI and other sources have not verified these claims. Developers are advised to wait for official information before building production systems around the undocumented alpha models.
