- This record represents the GPT-6 Astra release as exposed under the gpt-6-astra alias: the official model page lists both the default snapshot and the snapshot inventory as gpt-6-astra with no documented fixed dated snapshot, so applications cannot pin a dated revision. The OpenAI API platform, Azure Foundry hosting of the same alias, ChatGPT, the separate gpt-6-astra-fast variant, fine-tuned derivatives, and later GPT releases are separate service, application, or model boundaries.
