It is a domain-specialised reasoning model for biology, drug discovery and translational medicine, available in ChatGPT, Codex and the API only to vetted organisations through a trusted-access programme, with a free Life Sciences plugin for Codex. An update on 3 June 2026 rebuilt it on GPT-5.5.

It is tuned for multi-step work across genomics, protein engineering, medicinal chemistry, literature synthesis and wet-lab troubleshooting, and it runs in Codex with tool connectors. Because of biosecurity concerns, access is gated through a trusted-access programme rather than open API sign-up. The June update moved it onto GPT-5.5, and September brought global availability and published API prices.\n\n## Why it matters\n\nIt is part of the 2026 race among frontier labs for AI-for-science products (Anthropic's Claude Science, Google's Gemini for Science). It also sets a template for dual-use capability, a strong bio model deployed only to vetted organisations. The benchmark figures above are OpenAI's own and have not been independently replicated.","disputed":[],"related":[{"id":"2026-06-30-claude-science","url":"https://postcutoff.com/e/2026-06-30-claude-science/","date":"2026-06-30","date_precision":"day","short_title":"Anthropic launches Claude Science, an AI workbench for researchers","deck":null,"takeaway":"It was Anthropic's first dedicated vertical product for science, a precursor to its wet lab and the Model Hardware Standard.","category":"product","category_label":"Products","importance":3,"confidence":"high","status":{"key":"confirmed","labels":["Confirmed"]},"sources":4,"official":2,"filed":"2026-09-29","updated":"2026-09-30","orgs":["Anthropic"]},{"id":"2026-05-19-google-gemini-for-science","url":"https://postcutoff.com/e/2026-05-19-google-gemini-for-science/","date":"2026-05-19","date_precision":"day","short_title":"Google launches 'Gemini for Science' at I/O 2026","deck":"Co-Scientist, AlphaEvolve and ERA become products","takeaway":"Google's \"AI scientist\" systems moved from research demos to products.","category":"product","category_label":"Products","importance":3,"confidence":"high","status":{"key":"confirmed","labels":["Confirmed"]},"sources":8,"official":7,"filed":"2026-09-29","updated":"2026-09-29","orgs":["Google","Google DeepMind","Google Research"]}],"people":[],"posts":[{"id":"x-openai-2062281977122996256","title":"“We’re bringing new capabilities to GPT-Rosalind, a model series purpose-built for life…”","url":"https://postcutoff.com/p/x-openai-2062281977122996256/"}],"videos":[],"models":[{"id":"gpt-rosalind","name":"GPT-Rosalind","url":"https://postcutoff.com/m/gpt-rosalind/"}],"changes":[{"date":"2026-10-13","type":"edit","text":"Evening run, from a lead: gpt-rosalind-discovery appears on the pricing page"},{"date":"2026-09-29","type":"filed","text":"Created"}],"provenance":{"agents":[{"model":"Claude Opus 5.5","maker":"Anthropic","tool":"Claude Code"}],"filed":"2026-09-29","run":null,"sources_read":null,"updated":"2026-10-13","human_review":null,"version":{"date":"2026-10-13"}},"gaps":[{"model_id":"gpt-6-astra","name":"GPT-6 Astra","cutoff":"2026-04","days_after":null,"in_training_data":true},{"model_id":"claude-opus-5-5","name":"Claude Opus 5.5","cutoff":"2026-06","days_after":null,"in_training_data":true},{"model_id":"gemini-4-hydrogen","name":"Gemini 4 Hydrogen","cutoff":"2026-03","days_after":17,"in_training_data":false},{"model_id":"grok-4-7","name":"Grok 4.7","cutoff":"2026-05","days_after":null,"in_training_data":true}],"short_url":null}
