https://framerusercontent.com/images/D6PmL3tISzXL0GbLHg38ccQt0.jpg?width=2048&height=2048
Cerebrium's teams experience latency issues with large ML container images due to the sequential tar+gzip layer model, which was designed for magnetic tape access in the 1970s. A new approach, lazy loading with metadata indexing and chunk-based data blobs, can significantly reduce cold start times for large ML workloads by fetching only the necessary data on-demand.

Removing recursion via explicit callstack simulation
