Some developers, while examining a third-party-hosted mirror of OpenAI's model list, stumbled upon three previously unknown models named after auroras. These models—aurora-red-alpha, aurora-green-alpha, and aurora-blue-alpha—briefly surfaced on OpenAI's API model list before swiftly vanishing. When developers tried to invoke these models, they encountered a 503 error, signaling that no computing resources were currently available. This indicates that, although the model identifiers had been registered in the system, they were not accessible for regular use at that time. Given that this revelation did not stem from an official announcement, the intended purpose of these models and the likelihood of their official release remain ambiguous. Online communities have engaged in extensive speculation, with some suggesting that these models represent internal checkpoints for upcoming versions of GPT-6 Astra, boasting advanced features such as creative coding, long-range agent capabilities, visual processing, and 3D functionality. Others speculate that they may correspond to three distinct image models. Additionally, certain individuals assert that they have already tested these models on image generation platforms. Naturally, many users have also approached the situation with humor. As of now, OpenAI has yet to issue an official statement regarding the matter, leaving the true nature of the three Aurora models still a mystery.
