 FastEmbed is a lightweight, fast, Python library built for embedding generation. We [support popular text models](https://qdrant.github.io/fastembed/examples/Supported_Models/). Please [open a GitHub issue](https://github.com/qdrant/fastembed/issues/new) if you want us to add a new model.
 
-The default text embedding (`TextEmbedding`) model is Flag Embedding, presented in the [MTEB](https://huggingface.co/spaces/mteb/leaderboard) leaderboard. It supports "query" and "passage" prefixes for the input text. Here is an example for [Retrieval Embedding Generation](https://qdrant.github.io/fastembed/qdrant/Retrieval_with_FastEmbed/) and how to use [FastEmbed with Qdrant](https://qdrant.github.io/fastembed/qdrant/Usage_With_Qdrant/).

 ## 📈 Why FastEmbed?
 
 1. Light: FastEmbed is a lightweight library with few external dependencies. We don't require a GPU and don't download GBs of PyTorch dependencies, and instead use the ONNX Runtime. This makes it a great candidate for serverless runtimes like AWS Lambda. 
 
-2. Fast: FastEmbed is designed for speed. We use the ONNX Runtime, which is faster than PyTorch. We also use data parallelism for encoding large datasets.

-# Releasing FastEmbed
-
-This is a guide how to release `fastembed` and `fastembed-gpu` packages.
-
-## How to
-
-1. Accumulate changes in the `main` branch.
-2. Bump the version in `pyproject.toml`
-
-3. Rebase the `gpu` branch on `main` and resolve conflicts if occurred:
-
-```bash
-git checkout gpu
-git rebase main
-git push -f origin gpu
-```
-
-4. Draft release notes
-5. Checkout to `main` and create a tag, e.g.:
-
-```bash
-git checkout main
-git tag -a v0.1.0 -m "Release v0.1.0"
-```
-
-6. Checkout `gpu` and create a tag, e.g.:
-
-```bash
-git checkout gpu
-git tag -a v0.1.0-gpu -m "Release v0.1.0"
-```
-
-7. Push tags:
-
-```bash
-git push --tags
-```
-
-8. Verify that both packages have been published successfully on PyPI. Try installing them and verify imports.
-9. Create a release on GitHub with the written release notes.

 FastEmbed is a lightweight, fast, Python library built for embedding generation. We [support popular text models](https://qdrant.github.io/fastembed/examples/Supported_Models/). Please [open a Github issue](https://github.com/qdrant/fastembed/issues/new) if you want us to add a new model.
