Original GitHub issue: https://github.com/ollama/ollama/issues/1763

If I start to pull a model via /api/pull and then abort the request at let's say 2% and re-request it, it will not resume and start from 0%.
If I do it via ollama pull model it correctly resumes....

Did some more testing:
Start via /api/pull, go to 2%, abort -> run ollama pull model, no resume...
Start via ollama pull model, go to 2%, abort -> hit /api/pull, it resumes...

latest version, macos

hi @DennisKo, this is an interesting one. Thanks for reporting it. We will investigate this further. Were you testing this with the same model in both cases?

Yes, same model mistral. I am aborting both via a simple kill command (ctrl+c) in both cases. There is no abort controller in my fetch('/api/pull') implementation...

@DennisKo can you post the logs from the server for the POST /api/pull request? Specifically there should be something that looks like:

downloading <digest> in X Y MB part(s)

I just tested this and the resume functionality appears to be working correctly. I tried repulling a partially downloaded model, then hit Ctrl-C, and then started it again using the same command. Here's the output:

% curl -X POST http://localhost:11434/api/pull -d '{"name": "mixtral:8x7b-instruct-v0.1-q8_0"}'

You can see it takes a moment before it starts getting the correct new data, but it does resume from the correct location, and it starts pulling new data.

@DennisKo commented on GitHub (Jan 4, 2024):

I actually got confused with my test setup it seems. It was not because of the difference of api or cli, it was the way I was aborting AND killing the API server (ollama serve).
So new situation is: if I kill the API server, restart it and try to resume it does not work. Is this even a bug then? Or is that expected?

This is actually expected. The API server cleans up all of the partially downloaded images every time it restarts. You should be able to turn this off by setting OLLAMA_NOPRUNE=1 when you start the server.

Ah nice, I could not find anything about that.

In my quick tests with OLLAMA_NOPRUNE it still had problems with resuming if you shut down the server with a SIGINT. If I abort the API request via a proper client abort at least once, it correctly resumes, even after a server restart.

But I guess that's a different issue ...
