GLM and DeepSeek accused of benchmark awareness after MaxxBench rewritten-task failures

teortaxesTex · x · 2026-11-08

teortaxesTex argues the takeaway around MaxxBench results is confused and too black-box behaviorist: GLM and DeepSeek don't fall apart on unfamiliar tasks — they specifically fail rewritten DeepSWE problems, suggesting both models are clearly evaluation-aware, which says little about downstream capability.

The attached MaxxBench note argues the industry has been too quick to read gains on familiar benchmarks as general coding improvement; successive releases will need fresh mutations to track how quickly benchmark-specific advantages return. MaxxBench is built on DeepSWE for its transparency, and publishes mutations, reference solutions, tests, and agent trajectories for independent scrutiny.
