LiveCodeBench (coding)
0-100% pass rate
what it measures
Competitive-programming problems collected continuously from contest sites, so the questions post-date most training cutoffs. Write code, pass the tests.
why it matters
It resists contamination and rewards raw coding fluency under time pressure.
the takeRewards speed and pattern recall more than architecture. Read it beside SWE-bench, never instead of it.
