 # Using Goose for Free

 Goose is a free and open source developer AI agent that you can start using right away, but not all supported [LLM Providers][providers] provide a free tier. 
 
 Below, we outline a couple of free options and how to get started with them.
 
 
 ## Google Gemini
-Google Gemini provides free access to its AI capabilities with some limitations. To start using the Gemini API with Goose, you need an API Key from [Google AI studio](https://aistudio.google.com/app/apikey).

+## DeepSeek-R1
+
+:::warning
+Depending on the model's size, you'll need a relatively powerful device to smoothly run local LLMs.
+:::
+
+Ollama provides open source LLMs, such as `DeepSeek-r1`, that you can install and run locally.
+Note that the native `DeepSeek-r1` model doesn't support tool calling, however, we have a [custom model](https://ollama.com/michaelneale/deepseek-r1-goose) you can use with Goose. 
+
+
+
+1. Download and install Ollama from [ollama.com](https://ollama.com/download).
+2. In a terminal window, run the following command to install the custom DeepSeek-r1 model:
+
+```sh
+ollama run michaelneale/deepseek-r1-goose
+```

 ## Limitations
 
 These free options are a great way to get started with Goose and explore its capabilities. However, if you need more advanced features or higher usage limits, you can upgrade to a paid plan with your LLM provider.
