Monthly work summary for 2025-01 focused on the allenai/OLMo repository. Implemented GSM8K evaluation enhancements with a new logits_per_byte metric and integrated evaluation workflow with 5-shot prompting and gold-standard byte-per-bit calculations, enabling GSM8K benchmarking using the bpb metric. Hardened dataset handling by making label_id conversions robust in ICLMultiChoiceTaskDataset and OEEvalTask, avoiding string-to-long tensor issues and ensuring correct skipping of non-target continuations when label_id is a string. These efforts improve benchmarking fidelity, reduce runtime errors, and strengthen data integrity.
