The company says the mode delivers up to eight times the speed of Sol Standard with intelligence near Astra. API pricing is $12 per million input tokens and $60 per million output tokens. In Codex and ChatGPT Work, access is listed for Pro 500, eligible usage-based Enterprise, and credit-based Edu plans; Enterprise administrators must enable it. OpenAI says the mode is available in all supported regions, including US and EU data residency.
