Smolagents (gateway)

Route Smolagents’ underlying LLM calls through the Respan gateway to use 250+ models from different providers. Only your RESPAN_API_KEY is needed — no separate provider keys required.

Setup

$
pip install smolagents litellm

$
export RESPAN_API_KEY="YOUR_RESPAN_API_KEY"

1
import os
2
from smolagents import CodeAgent, LiteLLMModel

4
model = LiteLLMModel(
5
    model_id="openai/gpt-5.5",
6
    api_key=os.environ["RESPAN_API_KEY"],
7
    api_base="https://api.respan.ai/api",
8
)
9

agent = CodeAgent(tools=[], model=model)
11
print(agent.run("What is the capital of France?"))

Switch models

Use another OpenAI model ID through the same gateway-backed LiteLLM model wrapper.

1
LiteLLMModel(model_id="openai/gpt-5.5", api_key=..., api_base="https://api.respan.ai/api")
2
LiteLLMModel(model_id="openai/gpt-5-mini", api_key=..., api_base="https://api.respan.ai/api")
