@pdevine commented on GitHub (May 15, 2024):

Hey @levin8023 you can set the experimental flags:

OLLAMA_NUM_PARALLEL=2 and OLLAMA_MAX_LOADED_MODELS=2 when starting ollama serve (you can see the documentation for how to set that in the FAQ. That will allow 2 models to be loaded simultaneously and both run inference at the same time.

Hopefully this helps! I'll go ahead and close the issue.
