Nightly LLM Evals on Short-Lived GPUs Using Runcrate's CLI
A developer describes running LLM evaluations automatically every night instead of only before releases, so regressions surface early. The setup uses Runcrate's command-line tool to create a scheduled job that launches a fresh GPU, runs EleutherAI's lm-evaluation-harness, and shuts the machine down when the eval finishes. The example evaluates Qwen2.5-0.5B-Instruct on 200 ARC-Easy questions, with a run costing roughly a cent. The schedule includes a required maximum runtime to stop hung evals and a default setting that skips a run if the previous one is still active. The author reports running the commands on October 21, 2026, and notes that a PyTorch build must match the machine's CUDA driver version.
