 :::warning
 When using a Local LLM, OpenHands may have limited functionality.
+It is highly recommended that you use GPUs to serve local models for optimal experience.
 :::
 
-Ensure that you have the Ollama server up and running.
-For detailed startup instructions, refer to [here](https://github.com/ollama/ollama).
 
-This guide assumes you've started ollama with `ollama serve`. If you're running ollama differently (e.g. inside docker), the instructions might need to be modified. Please note that if you're running WSL the default ollama configuration blocks requests from docker containers. See [here](#configuring-ollama-service-wsl-en).

-## Pull Models
+- 2025/03/31: We release an open model OpenHands LM v0.1 32B that achieves 37.1% on SWE-Bench Verified ([blog](https://www.all-hands.dev/blog/introducing-openhands-lm-32b----a-strong-open-coding-agent-model), [model](https://huggingface.co/all-hands/openhands-lm-32b-v0.1)).
 
-Ollama model names can be found [here](https://ollama.com/library). For a small example, you can use
-the `codellama:7b` model. Bigger models will generally perform better.
 
-```bash
-ollama pull codellama:7b
-```
+## Download the model from Huggingface
 
-you can check which models you have downloaded like this:
+For example, if you are hoping to download [OpenHands LM 32B v0.1](https://huggingface.co/all-hands/openhands-lm-32b-v0.1):
 
 ```bash

-## Run OpenHands with Docker
+## Create an OpenAI-compatible endpoint with a model serving framework
 
-### Start OpenHands
-Use the instructions [here](../getting-started) to start OpenHands using Docker.
-But when running `docker run`, you'll need to add a few more arguments:
+### Serving with SGLang
+
+- Install SGLang following the official documentation: https://docs.sglang.ai/start/install.html
+- Example launch command for OpenHands LM 32B (with at least 2 GPUs):
 
 ```bash
-docker run # ...
-    --add-host host.docker.internal:host-gateway \
-    -e LLM_OLLAMA_BASE_URL="http://host.docker.internal:11434" \
-    # ...

+    --served-model-name openhands-lm-32b-v0.1 \
+    --port 8000 \
+    --tp 2 --dp 1 \
+    --host 0.0.0.0 \
+    --api-key mykey --context-length 131072
 ```
 
-LLM_OLLAMA_BASE_URL is optional. If you set it, it will be used to show
-the available installed models in the UI.
+### Serving with vLLM
 
+- Install vLLM following the official documentation: https://docs.vllm.ai/en/latest/getting_started/installation.html
+- Example launch command for OpenHands LM 32B (with at least 2 GPUs):
 
-### Configure the Web Application
+```bash
+vllm serve my_folder/openhands-lm-32b-v0.1 \
+    --host 0.0.0.0 --port 8000 \
+    --api-key mykey \
+    --tensor-parallel-size 2 \
+    --served-model-name openhands-lm-32b-v0.1
+    --enable-prefix-caching
+```
+
+### Configure OpenHands Application
 
 When running `openhands`, you'll need to set the following in the OpenHands UI through the Settings:
-- the model to "ollama/<model-name>"
-- the base url to `http://host.docker.internal:11434`
-- the API key is optional, you can use any string, such as `ollama`.
+- the model to `openai/openhands-lm-32b-v0.1` (`openai/`, and then `served-model-name` you set above)
+- the base url to `http://host.docker.internal:8000`
+- the API key is optional, you can use any string, such as `mykey` you set above.

-## Configuring the ollama service (WSL) {#configuring-ollama-service-wsl-en}
-
-The default configuration for ollama in WSL only serves localhost. This means you can't reach it from a docker container. eg. it wont work with OpenHands. First let's test that ollama is running correctly.
-
-```bash
-ollama list # get list of installed models
-curl http://localhost:11434/api/generate -d '{"model":"[NAME]","prompt":"hi"}'
-#ex. curl http://localhost:11434/api/generate -d '{"model":"codellama:7b","prompt":"hi"}'
-#ex. curl http://localhost:11434/api/generate -d '{"model":"codellama","prompt":"hi"}' #the tag is optional if there is only one
-```
-
-Once that is done, test that it allows "outside" requests, like those from inside a docker container.
-
-```bash
-docker ps # get list of running docker containers, for most accurate test choose the OpenHands sandbox container.
-docker exec [CONTAINER ID] curl http://host.docker.internal:11434/api/generate -d '{"model":"[NAME]","prompt":"hi"}'
-#ex. docker exec cd9cc82f7a11 curl http://host.docker.internal:11434/api/generate -d '{"model":"codellama","prompt":"hi"}'
-```
-
-## Fixing it
-
-Now let's make it work. Edit /etc/systemd/system/ollama.service with sudo privileges. (Path may vary depending on linux flavor)
-
-```bash
-sudo vi /etc/systemd/system/ollama.service
-```
-
-or
-
-```bash
-sudo nano /etc/systemd/system/ollama.service
-```
-
-In the [Service] bracket add these lines
-
-```
-Environment="OLLAMA_HOST=0.0.0.0:11434"
-Environment="OLLAMA_ORIGINS=*"
-```
-
-Then save, reload the configuration and restart the service.
-
-```bash
-sudo systemctl daemon-reload
-sudo systemctl restart ollama
-```
-
-Finally test that ollama is accessible from within the container
-
-```bash
-ollama list # get list of installed models
-docker ps # get list of running docker containers, for most accurate test choose the OpenHands sandbox container.
-docker exec [CONTAINER ID] curl http://host.docker.internal:11434/api/generate -d '{"model":"[NAME]","prompt":"hi"}'
-```

-# Local LLM with LM Studio
-
-Steps to set up LM Studio:
-1. Open LM Studio
-2. Go to the Local Server tab.
-3. Click the "Start Server" button.
-4. Select the model you want to use from the dropdown.
-
-
-Set the following configs:
-```bash
-LLM_MODEL="openai/lmstudio"
-LLM_BASE_URL="http://localhost:1234/v1"
-CUSTOM_LLM_PROVIDER="openai"
-```
-
-### Docker
-
-```bash
-docker run # ...
-    -e LLM_MODEL="openai/lmstudio" \
-    -e LLM_BASE_URL="http://host.docker.internal:1234/v1" \
-    -e CUSTOM_LLM_PROVIDER="openai" \
-    # ...
-```
-
-You should now be able to connect to `http://localhost:3000/`
-
-In the development environment, you can set the following configs in the `config.toml` file:
-
-```
-[core]
-workspace_base="./workspace"
-
-[llm]
-model="openai/lmstudio"
-base_url="http://localhost:1234/v1"
-custom_llm_provider="openai"
-```
-
-Done! Now you can start OpenHands by: `make run` without Docker. You now should be able to connect to `http://localhost:3000/`
-
-# Note
-
-For WSL, run the following commands in cmd to set up the networking mode to mirrored:
-
-```
-python -c  "print('[wsl2]\nnetworkingMode=mirrored',file=open(r'%UserProfile%\.wslconfig','w'))"
-wsl --shutdown
-```
