## **What is [Natural Language Processing API](https://www.edenai.co/technologies/text)?**

An [NLP API](https://www.edenai.co/technologies/text) is a tool that allows developers to add advanced language processing to their applications without creating it all from the beginning. NLP APIs provide pre-made features and models for tasks like [analyzing emotions](https://www.edenai.co/feature/emotion-detection), [interpreting text](https://www.edenai.co/feature/text-moderation-apis), [translating languages](https://www.edenai.co/feature/machine-translation-apis), [finding named entities](https://www.edenai.co/feature/named-entity-recognition-apis), and [summarizing text](https://www.edenai.co/feature/summarization-apis).

These tools help developers process and understand written data, gathering insights to improve natural language understanding in applications such as chatbots, virtual assistants, and tools for [analyzing sentiment](https://www.edenai.co/feature/sentiment-analysis-apis).



## **Top Open Source (Free) NLP models on the market**

For users seeking a cost-effective engine, opting for an open-source model is the recommended choice. Here is the list of the best NLP Open Source Models:

**1‍. [Rasa](https://github.com/RasaHQ/rasa)**

Rasa Open Source offers open-source natural language processing to break down complex user messages into intents and entities that chatbots can interpret. Using lower-level machine learning libraries such as Tensorflow and spaCy, Rasa Open Source provides highly customisable natural language processing software that is both approachable and precise.


**2. [Flair](https://github.com/flairNLP/flair)**

Flair offers cutting-edge natural language processing (NLP) models to enhance your text. Our models include named entity recognition (NER), sentiment analysis, and part-of-speech tagging (PoS). We also provide special support for biomedical data, sense disambiguation, and classification. Our models are available for an expanding range of languages.

**3. [spaCy](https://github.com/explosion/spaCy)**

spaCy is an advanced library that utilizes Natural Language Processing in Python and Cython. Developed using cutting-edge research, it was specifically designed for commercial use from its inception.

**4. [PyText](https://github.com/facebookresearch/pytext)**

PyText is a deep-learning-based NLP modeling framework constructed on PyTorch. Its goal is to fulfill the two concurrent demands of enabling swift experimentation and serving models at scale, which often conflict with each other. This is accomplished by providing uncomplicated and scalable interfaces and abstracts for model components, and by utilizing PyTorch's ability to export models for inferences via the optimized Caffe2 execution engine.


**5. [AllenNLP](https://github.com/allenai/allennlp)**

An open-source NLP research library. 



## **Cons of Using Open Source AI models**

‍While open source models offer many advantages, they also have potential drawbacks and challenges. Here are some cons of using open source models:

‍

- **Not Entirely Cost Free:** Open-source models, while providing valuable resources to users, may not always be entirely free of cost. Users often need to bear hosting and server usage expenses, especially when dealing with large or resource-intensive data sets.
- **Lack of Support**: Open source models may not have official support channels or dedicated customer support teams. If you encounter issues or need assistance, you might have to rely on community forums or the goodwill of volunteers, which can be less reliable than commercial support.
- **Limited Documentation**: Some open source models may have incomplete or poorly maintained documentation. This can make it difficult for developers to understand how to use the model effectively, leading to frustration and wasted time.
- **Security Concerns**: Security vulnerabilities can exist in open source models, and it may take longer for these issues to be addressed compared to commercially supported models. Users of open source models may need to monitor for security updates and patches actively.
- **Scalability and Performance**: Open source models may not be as optimized for performance and scalability as commercial models. If your application requires high performance or needs to handle a large number of requests, you may need to invest more time in optimization.
