In terms of cold starts, they mentioned their cold starts are 250ms which I am not sure what workload that is on, or if we have the same measure of cold starts. We have had quite a few customers that we have told us we are quite a bit faster 2-4 seconds vs ~10 seconds although we haven't confirmed this ourselves.
For a 30GB model, we have a few ways to speed this up such as using the Tensorizer framework from Coreweave, we cache model files in our distributed caching layer but I would need to test. We see reads of up to 1GB/s. If you tell me the model you are running (if open-source) I can get results to you - you can message me on our Slack/Discord community or email me at michael@cerebrium.ai or
