Share one live stream across multiple widgets (github.com)

A new TypeScript library, llm-coalesce, has been announced, enabling the sharing of a single live-streaming request from a large language model (LLM) across multiple concurrent callers. This provider-agnostic tool accepts an AsyncIterable or ReadableStream, allowing developers to integrate their preferred LLM SDK or transport. The library includes an express server and browser demo for users to compare independent requests against a shared stream, demonstrating its capabilities with minimal setup. This development is significant for the AI/ML community as it streamlines interactions with LLMs by enabling request coalescing and stream multicasting, which can enhance performance and reduce overhead during large-scale deployments. Users can coordinate multiple components in React and other frameworks while managing subscription cleanup automatically through the useLlmStream hook. The integration of this library with various frontend technologies represents a major step toward optimizing resource use in AI applications, making it easier for developers to implement efficient LLM features in their projects.
