*The Sentence Transformers configuration screen in PipesHub where you'll enter your Model Name*

PipesHub allows you to use Sentence Transformer embedding models to enable semantic search and document retrieval in your workspace. These models run locally inside PipesHub — no external API, no API key, and no usage costs.

## Required Fields

### Model Name \*

The Model Name is the only required field. It defines which Sentence Transformer model you want to use.

**Popular Sentence Transformer models include:**

* `all-MiniLM-L6-v2` - Lightweight general-purpose model, good balance of speed and quality
* `all-mpnet-base-v2` - Higher accuracy general-purpose model
* `paraphrase-multilingual-mpnet-base-v2` - Supports 50+ languages for multilingual applications

**How to choose a model:**

* For general purpose use, select `all-MiniLM-L6-v2`
* For higher accuracy when speed is less critical, select `all-mpnet-base-v2`
* For multilingual content, select `paraphrase-multilingual-mpnet-base-v2`
* Check the [Sentence Transformers documentation](https://www.sbert.net/docs/pretrained_models.html) for the full list of available models

## Configuration Steps

As shown in the image above:

1. Click **Configure** on the Sentence Transformers provider card
2. Specify your desired Model Name (marked with \*)
3. Click **Add Model** to save and validate

> Model Name is the only required field. No API key or external service is needed — the model runs locally inside PipesHub.

## Usage Considerations

* No external API calls are made — all embedding happens locally inside PipesHub
* No API key or billing setup required
* Larger models provide better quality but require more memory and are slower to load
* Most models support a maximum sequence length of 128–512 tokens per document chunk

## Troubleshooting

* If you encounter errors, verify the model name is spelled correctly
* For memory issues, consider switching to a smaller model such as `all-MiniLM-L6-v2`
* For multilingual applications, ensure you are using a model that supports your target languages
