"""Knowledge benchmark v3 (HARD) for vinland dual-MI50.
|
||
|
|
|
||
|
|
Round 1/2 topped out: leaders clustered at 38-40/40. This round is
|
||
|
|
built to make the frontier models bleed. Three question types, mixed:
|
||
|
|
|
||
|
|
[recall] - deep/obscure facts most models won't have memorized
|
||
|
|
[reason] - multi-step problems that must be computed, not recalled
|
||
|
|
[trap] - false-premise questions; the correct move is to reject
|
||
|
|
the premise, not answer within it (catches sycophancy)
|
||
|
|
|
||
|
|
Thinking is ENABLED this round (reason/trap questions need it), and
|
||
|
|
max_tokens is raised accordingly. Runs each model one at a time via
|
||
|
|
llama-server, one logfile per model. Writes to results_hard/ so it
|
||
|
|
does NOT collide with the round 1/2 results/ dir.
|
||
|
|
|
||
|
|
Grading is done afterward by handing results_hard/*.log to a strong
|
||
|
|
judge model. Trap questions are scored on whether the premise was
|
||
|
|
rejected. The expected answer is embedded in the log as a comment for
|
||
|
|
the judge, NOT shown to the model.
