Feb 1, 2026February 2026 — Delivered an automated TPU provisioning feature and improved observability in GoogleCloudPlatform/ml-auto-solutions. The new DAG automates TPU v6e-16 node pool provisioning, launches a jobset, and monitors uptime metrics, including a negative test case for invalid time ranges. This work reduces manual provisioning, speeds up TPU experiments, and strengthens validation and observability. No major bugs fixed this month.
