 ### Context Length Exceeded Error
 
 This error occurs when the input provided to Goose exceeds the maximum token limit of the LLM being used. To resolve this try breaking down your input into smaller parts. You can also use `.goosehints` as a way to provide goose with detailed context. Refer to the [Using Goosehints Guide][goosehints] for more information.

+### Using Ollama Provider
+
+Ollama provides local LLMs, which means you must first [download Ollama and run a model](/docs/getting-started/providers#local-llms-ollama) before attempting to use this provider with Goose. If you do not have the model downloaded, you'll run into the follow error:
+
+> ExecutionError("error sending request for url (http://localhost:11434/v1/chat/completions)")
+
+
+Another thing to note is that the DeepSeek models do not support tool calling, so all Goose [extensions must be disabled](/docs/getting-started/using-extensions#enablingdisabling-extensions) to use one of these models. Unfortunately, without the use of tools, there is not much Goose will be able to do autonomously if using DeepSeek. However, Ollama's other models such as `qwen2.5` do support tool calling and can be used with Goose extensions.

 ### Handling Rate Limit Errors
 Goose may encounter a `429 error` (rate limit exceeded) when interacting with LLM providers. The recommended solution is to use OpenRouter. See [Handling LLM Rate Limits][handling-rate-limits] for more info.
