Holy Moly. OpenAI has released GPT-6 Rosalind, a version of GPT-6 Astra designed to answer more dual-use biological research questions with fewer refusals. It uses the exact same model weights as GPT-6 Astra, with no additional training for this release. Compared with Rosalind 5.5: >Genomics-agent success: 16.7% → 37.7% >Medicinal chemistry: 28.9% → 49.6% >Life sciences research: 44.0% → 61.3% But its biosecurity behavior is markedly different despite using exactly the same model weights. GPT-Rosalind-6 passed OpenAI's Biosecurity Sensitive safety grader in 79.0% of tests, versus 99.8% for GPT-6 Astra. On Dual-Use biological prompts, it scored 84.6% versus Astra's 97.8%. OpenAI classifies it as High capability for biology and, inheriting Astra's assessment, Critical for cybersecurity. Access is restricted to approved researchers, companies and select government partners.
