## AI overview

AWS has extended Lambda SnapStart to container-image functions, allowing teams to combine larger dependency packages with sub-second startup times. The change removes a packaging tradeoff previously faced by workloads such as pandas- and NumPy-based Lambda functions.

## Source excerpt

AWS has extended Lambda SnapStart to container image functions, which hold up to 10 GB against 250 MB for zip archives. Teams previously chose between dependency headroom and sub-second startup. A Reddit thread from a month earlier shows what that cost: stripping whitespace and docstrings from installed packages to stay under the limit. By Steef-Jan Wiggers
