To use tools, provide the `tools` field when using Ollama's Chat API:
```python
import ollama
response = ollama.chat(
model='llama3.1',
messages=[{'role': 'user', 'content': 'What is the weather in Toronto?'}],
# provide a weather checking tool to the model
tools=[{
'type': 'function',
'function': {
'name': 'get_current_weather',
'description': 'Get the current weather for a city',
'parameters': {
'type': 'object',
'properties': {
'city': {
'type': 'string',
'description': 'The name of the city',
},
},
'required': ['city'],
},
},
},
],
)
print(response['message']['tool_calls'])
```
