OpenAI Ships Major GPT-Rosalind Update — Outperforms GPT-5.5 Across Life-Sciences Domains Using Up to 31% Fewer Tokens

OpenAI·medium signal

On June 3 OpenAI updated its life-sciences model GPT-Rosalind, combining GPT-5.5's agentic coding and tool use with stronger genomics and medicinal-chemistry intelligence, and opened the research preview to eligible organizations worldwide for the first time. Three new evals show it beating GPT-5.5 in every tested domain while consuming fewer tokens — 31% fewer on long-horizon genomics analyses. A paired Rosalind Biodefense program sponsors vetted access for outbreak modeling and countermeasure development.
