NextChat
NextChat is a self-hosted web application that provides a unified interface for interacting with multiple large language models. It functions as a conversational platform where users can manage and switch between diverse AI providers through configurable API backends, maintaining full control over their data and infrastructure.
The platform features a persistent session layer designed to handle long-running dialogues by managing message history and context. It distinguishes itself through a structured prompt engineering environment that allows for the development and application of templates to refine model inputs. To ensure consistent performance during extended interactions, the application includes automated context window compression and dynamic prompt injection, which adjust historical message arrays to fit within model token limits.
The software supports secure deployment via containerization, utilizing server-side proxying to manage sensitive API keys and authentication headers. It also incorporates local browser storage for low-latency access and offers options for synchronizing chat records across multiple sessions and devices. The application is configured through environment variables, allowing for flexible integration into private hosting environments.
