Is there a specific recommended format (like 🤗safetensors) for storing tensors/model in the model store. There is no mention to it in the official doc https://docs.bentoml.com/en/latest/guides/model-store.html. I've just read your very great blog article and you detail how you leveraged the zero copy capabilities of safetensor for model loading. Thanks for your help.

Safetensors is a great serialization format for storing weights. There is no limit to what you choose to use since you can customize the model loading logic in the service constructors.

Ok thanks, and is using safetensors will result in faster cold start compared to the normal pytorch serialization format (which is pickle under the hood I think)?

Yes. We expect so.
