July 2025 — mlcommons/inference: Delivered MLPerf evaluation readiness and test infra improvements, enhanced CI flow, expanded tests for ResNet50/Retinanet, refactored accuracy evaluation for MLPerf JSON logs, and updated DeepSeek-R1 thresholds to improve compliance. Fixed DeepSeek-R1 sequence length constraint (32k -> 20k) with docs and config updates. Result: more reliable MLPerf submissions, reduced run-time/resource usage, and stronger testing coverage across the evaluation pipeline.

Jun 1, 2025

June 2025: Delivered a comprehensive DeepSeek-R1 reference model and evaluation tooling for mlcommons/inference, enabling cross-backend inference evaluation and streamlined deployment. Implemented multi-backend support (PyTorch, vLLM, SGLang) with backend-specific Dockerfiles and setup scripts, and provided MLPerf utilities for dataset preparation, SUT implementations, and result processing to support end-to-end evaluation across engines. Fixed robust MLPerf log ingestion to support both standard JSON arrays and newline-delimited JSON, ensuring accurate evaluation regardless of log structure.
