- Sources: primary, discussion
- Summary: Version 4.2 of the index doubles the private held-out share from v4.1 to 40 percent. GPQA Diamond is retired as saturated.
- Why it matters: Scores quoted against v4.1 and v4.2 are not comparable, so any vendor claim citing the index needs its version stated.
