OpenAI expands life sciences model lineup with new pricing

OpenAI has updated its API pricing page to include gpt-rosalind-discovery, a second model in its GPT-Rosalind life sciences series. The new model is priced at $5.00 per million input tokens, $0.50 for cached input, and $25.00 per million output tokens.

This pricing matches the existing gpt-rosalind-research model. While the pricing page note specifically mentions billing for the research model began on 5 October 2026, it also indicates that eligible organizations will receive access to subsequent GPT-Rosalind models as they are released. This expansion suggests OpenAI is transitioning the GPT-Rosalind series into a structured product line for the life sciences sector.
