January 2025: Stabilized evaluation workflows on Habana Gaudi hardware and refreshed evaluation tooling to support ongoing model development and deployment. Delivered a targeted bug fix for dynamic Mixture-of-Experts (MoE) handling that prevents pytest failures on Gaudi1 by gating the dynamic MoE forward path to non-training and non-quantized configurations, and extended device-name logic to recognize gaudi3. Upgraded the LM Evaluation Harness to 0.4.7, updating requirements and refactoring run_lm_eval.py to align with the new library structure. These changes reduce test flakiness, improve evaluation accuracy and throughput, and prepare the codebase for broader hardware compatibility.
