ModelFusion is an open-source TypeScript library designed to simplify the development of AI-powered applications by providing a unified abstraction layer for interacting with different AI model providers. The framework allows developers to integrate large language models and other generative systems into JavaScript and TypeScript applications through a consistent and standardized API. Instead of writing separate integration logic for each provider, developers can use ModelFusion to handle common operations such as text generation, structured object generation, streaming responses, and tool calls. The library supports a wide range of model types, including text generation models, vision models, text-to-speech engines, speech-to-text systems, and embedding models. It also includes built-in production features such as observability hooks, logging, automatic retries, and error handling mechanisms that improve reliability when deploying AI systems in real-world environments.

Features

  • Unified API for interacting with multiple AI model providers
  • Support for multimodal models including text, image, speech, and embeddings
  • Streaming response capabilities for real-time AI output
  • Type inference and schema validation for structured model responses
  • Production-ready tooling including logging, observability, and retry logic
  • Compatibility with serverless environments and modern JavaScript frameworks
