Report LHTB as pass@0.95 (6.5) instead of mean reward

#27
by zli12321 - opened

Switches the reported LHTB metric from mean reward to pass@0.95, the share of the 46 tasks solved at reward >= 0.95 (3/46). The mean reward is retained in notes.

Friendly bump on this one, because the un-merged state is now actively misleading rather than just out of date.

The LHTB leaderboard metric changed from mean reward (a 0-100 scale) to the number of tasks solved out of 46. Every other entry on the board has been updated, so they now read 6, 3, 2, 1, 0.

main here still carries the old value of 38.5. On the new 0-46 scale that parses as "38.5 of 46 tasks solved", which overstates MiniMax-M3 by roughly 12x -- the actual figure is 3 of 46 at reward >= 0.95. Because the leaderboard prefers the value on main over an open PR, MiniMax-M3 currently sits at rank 1 on a number that no longer means what the column means.

This PR replaces it with value: 3 and keeps the mean reward (38.5) in notes, so no information is lost. Merging it is the only way to correct the row -- we can't write to main from our side.

Happy to adjust the wording or close this if you would rather submit the number yourselves.
