Artificial Analysis notes v5 tasks demand far more work: median output tokens per Intelligence Index task rose two-thirds, from 35k in v4.3 to 59k. Agentic evaluations (Terminal-Bench-Science, Terminal-Bench 4.0, AA-Briefcase, FrontierCode 2.0) make up 55% of index weight but a median 88% of output tokens, with Terminal-Bench-Science alone accounting for about a third of tokens per task.
