Modal launches Notebooks with GPU kernels that start in under 5 seconds

Modal Notebooks is now generally available to all Modal customers after a limited beta last month. The collaborative notebook environment runs on a GPU-enabled Python kernel that reaches a ready state in under 5 seconds on arbitrary container images and hardware up to 256 vCPUs and 8 H100/B200 GPUs, with auto-idle shutdown, shared Volumes and Secrets, and real-time multi-cursor editing. Modal says over 5,000 accounts ran 200,000 code cells during the August beta, and upcoming features include memory snapshots, one-click export to Modal Apps, and scheduled runs.
