## **What is [Machine Translation API](https://www.edenai.co/feature/machine-translation-apis?referral=top-free-translation-tools-apis-and-open-source-models)?**
Machine translation (MT), also known as [automated translation](https://www.edenai.co/feature/machine-translation-apis?referral=top-free-translation-tools-apis-and-open-source-models), refers to the automated process by which computer software translates text from one language to another without human intervention. There are three main approaches to machine translation: rule-based, statistical and neural network.

Modern machine translation software often supports customisation based on specific domains or professions, improving the quality of translations by narrowing the range of acceptable substitutions.

‍

These APIs are used in a wide range of applications, including websites that offer multilingual content, mobile apps for travelers, customer support systems that provide translations, and more.

‍

## **Cons of Using Open Source AI models**
‍While open source models offer many advantages, they also come with some 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 expenses related to hosting and server usage, especially when dealing with large or resource-intensive data sets.
**- Lack of Support:** Open source models may not come with 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 actively monitor for security updates and patches.
**- 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.
