OpenAI has launched Rosalind Biodefense, a new programme giving trusted developers sponsored access to GPT‑Rosalind — its frontier reasoning model built for life sciences research — to build biodefense and pandemic preparedness applications.
The initiative is aimed at organizations working across the biological defense stack, including epidemiological modeling, early detection, screening, non-pharmaceutical interventions, and medical countermeasure development. OpenAI says it will sponsor access to GPT‑Rosalind and provide launch support to qualifying academic, nonprofit, government-affiliated, and mission-driven teams.
Four organisations are named as launch partners: Fourth Eon, SecureDNA, SecureBio Detection, and ProEquip.
Alongside the developer programme, OpenAI is extending trusted access to GPT‑Rosalind for select US government and allied partners with approved public health and biodefense missions. Named partners include Lawrence Livermore National Laboratory, which is applying the model to medical countermeasure development; Johns Hopkins Applied Physics Laboratory, which intends to integrate GPT‑Rosalind into a protein-engineering platform; and the Coalition for Epidemic Preparedness Innovations (CEPI), which is focused on its 100 Days Mission, including response to the current Ebola outbreak.
The announcement follows OpenAI's classification of ChatGPT agent in July 2025 as its first model designated High Capability in biology under its Preparedness Framework, triggering a set of safeguards for dual-use biological requests.
