Your AI and this story

  • GPT-6 AstraIn its training data
  • Claude Opus 5.5In its training data
  • Gemini 4 Hydrogen17 days after its cutoff
  • Grok 4.7In its training data

It is after the cutoff of Gemini 4 Hydrogen, and can be in the training data of GPT-6 Astra, Claude Opus 5.5 and Grok 4.7.

Key facts

  • Named after Rosalind Franklin; launch partners included Amgen, Moderna, the Allen Institute and Thermo Fisher Scientific; Novo Nordisk partnership announced 14 April 2026
  • Launch claims (per press): BixBench pass@1 0.751 vs GPT-5.4 0.732; beat GPT-5.4 on 6 of 11 LABBench2 tasks (largest gain on CloningQA); in a Dyno Therapeutics RNA evaluation its best-of-10 submissions ranked above the 95th percentile of human experts on prediction and ~84th on sequence generation
  • Codex Life Sciences research plugin connects models to 50+ scientific tools and data sources (freely available)
  • 3 June 2026 update: brings GPT-5.5’s agentic coding and tool use; OpenAI says it uses 31% fewer tokens than GPT-5.5; new LabWorkBench eval 63.2% vs GPT-5.5 55.8%; Rosalind Biodefense programme for US government and allied public-health partners
  • 11 Sept 2026: out of research preview for eligible organisations globally (ChatGPT, Codex, API); API id gpt-rosalind-research at $5 input / $0.50 cached / $25 output per 1M tokens, billing from 5 Oct 2026
  • Access requires organisational eligibility, governance controls and an approved research deployment; ordinary API accounts cannot call it
  • October 2026: OpenAI’s API pricing page lists a second id, gpt-rosalind-discovery, at the same $5 / $0.50 / $25 per 1M input / cached input / output tokens as gpt-rosalind-research (checked Oct 13, 2026). OpenAI has not announced it; TestingCatalog noticed it on Oct 10. What distinguishes it from the research model is not documented

What happened

OpenAI launched its first model specialised for the life sciences. 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.

Why it matters

It 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.
