@girish thanks for packaging Ollama ! I can confirm that it works for auto-tagging 
From the Ollama app terminal, get the IP with ifconfig | grep "inet " | grep -Fv 127.0.0.1 | awk '{print $2}'
Add the IP to the variable NEXT_PUBLIC_OLLAMA_ENDPOINT_URL + :11434 in the Linwarden env file. Ex. http://172.18.16.199:11434
Follow Ollama docs to pull a model and the follow Linkwarden docs https://docs.linkwarden.app/self-hosting/ai-worker and https://docs.linkwarden.app/Usage/ai-tagging to enable the feature.
