Modal launches GPU memory snapshots for sub-second serverless cold starts
GPU Memory Snapshots: Supercharging sub-second startup
AI summary
Modal announced GPU memory snapshots in alpha, extending its existing checkpoint/restore system to capture GPU vRAM, CUDA kernels, streams and contexts so GPU workloads restore from a frozen state instead of rebuilding CUDA state after boot.
Why it matters
Modal adds GPU state to its memory snapshots, cutting cold boots for torch.compile and vLLM workloads by up to 10x and making scale-to-zero more practical.
