Langflow is an open-source, Python-powered framework that simplifies the development of multi-agent and Retrieval-Augmented Generation (RAG) applications. Its visual flow builder allows developers to design and test workflows with ease, enabling rapid prototyping and deployment.
Novita AI provides a range of advanced Model APIs, including Llama, DeepSeek, and Mistral, as well as resources like serverless computing and GPU instances. By integrating Novita AI’s APIs into Langflow, developers can unlock a powerful environment for AI application development.
What is Langflow?
Langflow is an open-source, Python-based framework designed for building AI-driven applications. It features a visual flow builder that enables developers to create multi-agent systems and Retrieval-Augmented Generation (RAG) workflows.
Through its drag-and-drop interface, Langflow simplifies the integration of components such as prompts, language models, and vector databases. This abstraction reduces the need for extensive coding, allowing developers to focus on application logic.
Langflow is model-agnostic, meaning it supports any large language model (LLM) or vector store. Its modular and scalable architecture makes it suitable for diverse AI use cases, from chatbots to document QA systems.
