-I'm currently exploring again how can I use LLM without internet, one of the way is using ollama.
+I've been exploring ways to use Ollama offline, one approach being Ollama. My go-to LLM UI is [Open WebUI](https://github.com/open-webui/open-webui), which I manage using Docker Compose. You can see my setup in more detail [here](https://brain.irfansp.dev/#/page/openweb-ui)
 
-I have my favorite LLM UI which is [Open WebUI](https://github.com/open-webui/open-webui) and I currently use the docker-compose to manage Open WebUI, my setup can be seen [here](https://brain.irfansp.dev/#/page/openweb-ui).
+I'm looking for an alternative solution, where I keep the Open WebUI running in the container and run Ollama locally on my host machine. The reason behind this is because I have downloaded some models on my host and I think it will be much harder if I use or run the Ollama as a container.
 
-Now, I want something different, which is keeping my Open WebUI setup on container but keep the Ollama on my host machine.
-
-There is the solution if we just use docker without docker-compose on this problem, and it can be seen [here](https://github.com/open-webui/open-webui#troubleshooting). But, in this case I run my openweb-ui using docker-compose so it's kinda different.
-
-After some searched, I found that we can just add parameter `extra_hosts` in the Open WebUI container so that it can connect to Ollama in my host machine, specifically adding following:
+After some research, I found that I can use the `extra_hosts`` parameter in Docker Compose to map host.docker.internal to the host machine's gateway IP. I added the following configuration to my Open WebUi container in the docker-compose.yml file:
 
 ```yaml
 extra_hosts:
   - "host.docker.internal:host-gateway"
 ```
 
-The extra_hosts directive adds an entry to the container’s /etc/hosts file, mapping host.docker.internal to the host’s gateway IP.
-
-and in this case, to connect my Open WebUI to Ollama on my host machine I can use <http://host.docker.internal:11434>
+This directive updates the container's /etc/hosts file, mapping host.docker.internal to the host machine's gateway IP. With this setup, I can access Ollama on my host machine by using <http://host.docker.internal:11434> from the Open WebUI.
