Artificial Analysis v5 widens the open-weight gap to 12 points — Oct 28

Artificial Analysis rebuilt its Intelligence Index, and on the new version the open-weight gap to the leaders grew from 3 points to 12, which undercuts last week's parity story. Anthropic is pushing on two fronts, a 40% government discount and a drug-development program whose evidence is strongest in document review, while Bank of America and a new wrongful-death suit push liability back onto agent delegation. DeepSeek's latest point update also drew a safety study showing it overriding another agent's compute allocation.
