summary
  • You need to set up an AI API that is requested if and only if the main AI API does not perform well (or is down).
  • This approach is required if you look for extremely high accuracy.
  • A unified API for all providers: simple and standard to use, quick switch between providers, access to the specific features of each provider.
  • Best Artificial Intelligence APIs of the market: big cloud providers (Google, AWS, Microsoft, and more specialized engines).
  • Eden AI aggregates multiple providers for this feature.

We are pleased to announce that Lettria has been integrated into Eden AI platform.

What is Lettria? 

Lettria is a Natural Language Processing (NLP) tool that specializes in French understanding. Their objective is to help developers in creating the next generation of intelligent language-based apps, such as chatbots, translation tools, text analysis, and personal assistants.

The Lettria platform allows all organizations, from small businesses to large corporations, to analyze textual data to make the best strategic decisions. The company brings tech and business teams together in a single, collaborative, no-code interface to support them step-by-step in the realization of their textual data processing projects. The team has been attempting to overcome the fundamental NLP obstacle and democratize the use of simple and collaborative technologies. 

This powerful NLP engine can be directly used on Eden AI with French and English.

Why do we offer Lettria in addition to other NLP APIs?

Eden AI offers Lettria AI solutions on its platform amongst several other technologies. We want our users to have access to multiple AI engines and manage them in one place so they can reach high performance, optimize cost and cover all their needs. There are many reasons for using multiple AI APIs :  

Fallback provider is the ABCs.

You need to set up an AI API that is requested if and only if the main AI API does not perform well (or is down). You can use the confidence score returned or other methods to check provider accuracy.

Performance optimization.

After the testing phase, you will be able to build a mapping of AI vendors' performance that depends on the criteria that you chose. Each data that you need to process will be then sent to the best API.

Cost - Performance ratio optimization.

This method allows you to choose the cheapest provider that performs well for your data. Let's imagine that you choose Google Cloud API for customer "A" because they all perform well and this is the cheapest. You will then choose Microsoft Azure for customer "B", a more expensive API but Google performances are not satisfying for customer "B". (this is a random example)

Combine multiple AI APIs.

This approach is required if you look for extremely high accuracy. The combination leads to higher costs but allows your AI service to be safe and accurate because AI APIs will validate and invalidate each other for each piece of data.
