OpenAI Releases LifeSciBench, a 750-Task Benchmark Grading AI Models on Real Life-Science Research With Expert-Written Rubric

Why it matters

OpenAI's LifeSciBench reveals a critical capability gap: frontier models struggle with domain-specific, reasoning-heavy tasks in high-stakes research. This matters because it shows where AI adoption in biotech will stall—and where the next wave of model improvement must focus.

Key signals

  • 750-task benchmark across 7 biological domains and 7 research workflows
  • Built by 173 PhD scientists with 19,020 rubric criteria
  • GPT-Rosalind (best model) passes only 36.1% of tasks
  • Evaluation grades reasoning and decision-making, not just recall
  • Significant headroom identified in artifacts, exact outputs, and operational calls

The hook

36.1%. That's how many real life-science research tasks the best AI model passes. OpenAI just released LifeSciBench—750 expert-authored benchmarks that grade reasoning, not recall.

OpenAI's LifeSciBench evaluates whether frontier AI can handle real life-science research across 750 expert-authored tasks, seven workflows, and seven biological domains. Built by 173 PhD scientists with 19,020 rubric criteria, it grades reasoning and decisions, not just recall. The best model, GPT-Rosalind, passes 36.1%, leaving large headroom on artifacts, exact outputs, and operational calls.
