September 2025: Delivered critical feature enhancements and robustness improvements for oracle/accelerated-data-science. The GPU Shape Recommendation Improvements with Service Managed Models (SMMs) enables direct processing of deployment configurations in AQUA for more accurate shape suggestions, with refined model configuration handling, output formatting, and naming consistency; unit tests updated to align model configuration fetching and IDs. Fixed Service Pack Retrieval Robustness by removing an external API dependency and relying on object storage, improving reliability and error reporting. These changes reduce deployment risk, accelerate SMM adoption, and improve governance and observability across the model deployment workflow.
