Evaluation: Benchmarks, Evals, LM Harness
Goodhart's Law: when a measure becomes a target, it ceases to be a good measure. Every frontier lab games benchmarks. MMLU scores go up while models still can't reliably count the number of R's in "strawberry." The only eval that matters is YOUR eval -- on YOUR task, with YOUR data.
Visual edition planned
This lesson isn’t interactive yet.
It is part of the curriculum and will get the same treatment as Phase 1 — a visual cover, hands-on labs, derivations with numeric checks and a quiz. Until then, the original lesson is the best place to read it:
Part of Phase 10 — LLMs from Scratch. Use the previous / next cards below to keep browsing the phase.
