+## Quick testing with local LLMs
+As mentioned [here](https://langroid.github.io/langroid/tutorials/non-openai-llms/#quick-testing-with-non-openai-models), 
+you can run many of the [tests](https://github.com/langroid/langroid/tree/main/tests/main) in the main langroid repo against a local LLM
+(which by default run against an OpenAI model), 
+by specifying the model as `--m <model>`, 
+where `<model>` follows the syntax described in the previous sections. Here's an example:
+
+```bash
+pytest tests/main/test_chat_agent.py --m ollama/mixtral
+```
+Of course, bear in mind that the tests may not pass due to weaknesses of the local LLM.
