Generative AI

A modern system of record for your generative AI application

Start for free

Three reasons to develop your generative AI apps on Fauna

Data model flexibility with relations applied on documents

Fauna supports unstructured data without sacrificing the ability to traverse relationships between critical entities within your generative AI application via joins, filters, or foreign keys - allowing you to adapt to shifting access patterns as your application evolves over time.

Scalability and compatibility with vector databases

Fauna complements your vector database by serving as a transactional engine for storing general application and user data, metadata, and context. Filter or aggregate data in specific ways to get the desired output through Fauna’s powerful and intuitive query language.

API delivery model and composability with modern tooling

Generative AI applications are built with modern architectural components such as APIs and serverless functions. Fauna is delivered as an API, which allows it to seamlessly integrate with different pieces of your application without brittle integration code.

Partners & Integrations

We play well with others

Fauna is compatible with cloud infrastructure from AWS, Azure, and GCP and integrated with edge compute functions including Cloudflare Workers, Fastly Compute@Edge, and AWS Lambda. See our partners page for more integrations with leading third-party providers.

What is generative AI?

Generative AI refers to the use of artificial intelligence techniques to create new content, such as images, videos, text, or even music, that imitates or generates novel and realistic outputs. It involves training AI models on vast amounts of data to learn patterns and generate new content based on that learning. Generative AI enables machines to produce creative and original outputs, often resembling human-created content.

How is a database used in a generative AI application?

Databases play a crucial role in generative AI applications by storing and managing the vast amount of training data and generated content. During the training phase, the database is used to store the training dataset, which serves as the input for training the generative AI model. The database allows efficient retrieval and processing of the training data, enabling the model to learn from the patterns and correlations in the data. In the deployment phase, the database is utilized to store and retrieve the generated content. The generated outputs can be saved in the database for future reference or used to enhance user experiences in applications like recommendation systems, personalized content generation, or creative tools.
