[any free and unpaid alternative for Inference Providers?]

while executing the [notebook](https://colab.research.google.com/github/huggingface/agents-course/blob/main/notebooks/unit2/smolagents/multiagent_notebook.ipynb) on **unit2. multi agent systems**, i got the following client error for [Inference Providers](https://huggingface.co/blog/inference-providers):

```python

> result = agent.run(task)

HTTPError: 402 Client Error: Payment Required for url: https://huggingface.co/api/inference-proxy/together/v1/chat/completions

The above exception was the direct cause of the following exception:

HfHubHTTPError Traceback (most recent call last)
