## Choose when

### Choose fastembed if…

- License: fastembed is Apache-2.0, hazm is MIT.
- Requirements: Does not require Docker, making the setup straightforward for Python environments..
- Tags unique to fastembed: openai, rag, retrieval-augmented-generation, vector-search.
- Also covers Vector Databases.
- When you need to generate high-quality embeddings quickly in Python.

### Choose hazm if…

- License: hazm is MIT, fastembed is Apache-2.0.
- Tags unique to hazm: dependency-parser, lemmatization, natural-language-processing, nlp.
- Also covers Model Training.
- When working exclusively with Farsi language texts where comprehensive processing tools like dependency parsing or POS tagging are required.

## When NOT to use fastembed

- If your project is not using Python, as Fastembed does not offer support for other programming languages directly.
- In scenarios demanding heavy customization or fine-tuning at a lower level than what Fastembed provides out-of-the-box. Consider alternatives that may offer more flexibility.

## When NOT to use hazm

- If the project involves languages other than Persian, as Hazm lacks capabilities for multilingual support beyond Farsi.
- When advanced machine learning models requiring extensive training data and resources are necessary; Hazm provides utilities but does not include state-of-the-art models.
