Latitude AI capabilities

Tool calling

Use Latitude AI’s tool calling feature to trigger external functions:

Python

from portkey_ai import Portkey

portkey = Portkey(api_key="PORTKEY_API_KEY")

tools = [{
    "type": "function",
    "function": {
        "name": "getWeather",
        "description": "Get the current weather",
        "parameters": {
            "type": "object",
            "properties": {
                "location": {"type": "string", "description": "City and state"},
                "unit": {"type": "string", "enum": ["celsius", "fahrenheit"]}
            },
            "required": ["location"]
        }
    }
}]

response = portkey.chat.completions.create(
    model="@latitude/qwen-2.5-7b",
    messages=[
        {"role": "system", "content": "You are a helpful assistant."},
        {"role": "user", "content": "What's the weather like in Delhi?"}
    ],
    tools=tools,
    tool_choice="auto"
)

print(response.choices[0].finish_reason)

JSON output

Force structured JSON responses from Latitude AI models:

Python

from portkey_ai import Portkey

portkey = Portkey(api_key="PORTKEY_API_KEY")

response = portkey.chat.completions.create(
    model="@latitude/qwen-2.5-7b",
    messages=[
        {"role": "system", "content": "Respond in JSON format with keys: answer, confidence"},
        {"role": "user", "content": "What is the capital of France?"}
