A busy week for frontier AI labs in health and bio:
- Anthropic Life Sciences: new biology group and wet lab; 950 Claude agents spent 21 hours searching DNA and uncovered a previously uncharacterized enzyme system with CRISPR-like features.
- Anthropic × OpenEvidence: free clinical decision support for doctors across 100 low- and middle-income countries.
- Cheaper frontier models: Anthropic launched Opus 5.5 at 40% lower cost; OpenAI launched GPT-6 Sol and Luna at roughly 50% lower prices than the models they replace.
- OpenAI's MentalHealthBench: built with 80+ psychiatrists and psychologists across 22 countries to evaluate AI on everyday and acute mental health conversations.
