The maximum memory limit for an App Engine instance depends on the instance class that you choose. The default limit is 128 MB. The following classes are currently available:

  • F1 and B1 - 128 MB
  • F2 and B2 - 256 MB
  • F4 and B4 - 512 MB
  • F4_1G, B4_1G - 1024 MB

Edit: Second generation instances have double the memory:

  • F1 and B1 - 256 MB
  • F2 and B2 - 512 MB
  • F4 and B4 - 1024 MB
  • F4_HIGHMEM and B4_HIGHMEM - 2048 MB
  • B8 - 2048 MB
