Getting Started

ModelFusion is an abstraction layer for integrating AI models into JavaScript and TypeScript applications, unifying the API for common operations such as text streaming, object generation, and tool usage. It provides features to support production environments, including observability hooks, logging, and automatic retries. You can use ModelFusion to build AI applications, chatbots, and agents.

  • Vendor-neutral: ModelFusion is a non-commercial open source project that is community-driven. You can use it with any supported provider.
  • Multi-modal: ModelFusion supports a wide range of models including text generation, image generation, vision, text-to-speech, speech-to-text, and embedding models.
  • Type inference and validation: ModelFusion infers TypeScript types wherever possible and validates model responses.
  • Observability and logging: ModelFusion provides an observer framework and out-of-the-box logging support.
  • Resilience and robustness: ModelFusion ensures seamless operation through automatic retries, throttling, and error handling mechanisms.
  • Built for production: ModelFusion is fully tree-shakeable, can be used in serverless environments, and only uses a minimal set of dependencies.

ModelFusion is getting closer to a stable v1, which is expected in Q2/2024. The main API is now mostly stable, but until version 1.0 there may be breaking changes. Feedback and suggestions are welcome.
