[QUESTION] Clarify Payment Required for completing Unit 2 notebooks

For the notebook for [components.ipynb]() I ran the `IngestionPipeline` function as follows:

```py
from llama_index.embeddings.huggingface_api import HuggingFaceInferenceAPIEmbedding
from llama_index.core.node_parser import SentenceSplitter
from llama_index.core.ingestion import IngestionPipeline

# create the pipeline with transformations
pipeline = IngestionPipeline(
transformations=[
SentenceSplitter(),
HuggingFaceInferenceAPIEmbedding(model_name="BAAI/bge-small-en-v1.5"),
]
)

# run the pipeline sync or async
nodes = await pipeline.arun(documents=documents[:10])
nodes
```

I got the following outcome and looks like this .ipynb can't be executed without a payment route:

```python
---------------------------------------------------------------------------

```

is there any free and open alternatives?
