Original GitHub issue: https://github.com/ollama/ollama/issues/4701

Hi,
I would like to be able to update models that I have previously downloaded.
When I do this, ollama pull does 2 steps:

  1. It checks if the model is up-to-date and if not, it downloads the newest version
  2. It checks the sha256 digest

Unfortunately, step 2 is always performed, even when it is not needed, which is very slow (I have a lot of models).
Therefore, I propose the following behavior:

  • ollama pull should do step 1. and then step 2. only if the model has been updated
  • a new command ollama check could allow to check the sha256 digest when needed by the user.

Thanks.

update all models use

ollama list | awk 'NR>1 {print $1}' | xargs -I {} sh -c 'echo "Updating model: {}"; ollama pull {}; echo "--"' && echo "All models updated."

I have a similar script, but the problem remains the same: ollama checks all sha256 digests, which is very slow.
