OpenAI lists this life sciences model first among its Rosalind models. Access is limited to approved internal research through OpenAI’s trusted-access program. Cached input is billed at $1.50 per million tokens, a 30-minute cache write at $18.75 and a 12-hour cache write at $37.50. A request with 10,000 input tokens and 2,000 output tokens costs about $0.30 before caching. The API model name is gpt-6-rosalind. OpenAI does not publish its context window or output limit. GPT-Rosalind charges $5 for input and $25 for output, so the same request costs about $0.10 there, one third of the price.
