Fable 5 users will now experience many fewer “fallbacks”—where the system switches to a less capable model after they make a biology-related query. In our testing, this update reduced biology-related fallbacks by about 85% across our product surfaces. 1 Fable 5 will thus be able to assist with a wider range of biology tasks. In practice, users should see far fewer fallbacks on everyday health and educational questions—for example, interpreting lab results, understanding symptoms, and learning about biology in an educational context. Healthcare professionals will be able to receive more support from Fable 5 on clinical tasks. We believe the greatest opportunity for AI to positively affect the world is in biology and medicine, and we're investing significantly in building a responsible way to give biologists frontier access.
