Ollama Agent Basic Example
|
|
|
|
This sample demonstrates implementing a Ollama agent with basic tool usage.
|
|
|
|
Ensure to install Ollama and have a model running locally before running the sample
|
|
Not all Models support function calling, to test function calling try llama3.2 or qwen3:4b
|
|
Set the model to use via the OLLAMA_MODEL environment variable or modify the code below.
