A Rust Shim for Unifying Multi-Model API Requests

sanjay920 · reddit · 2026-07-15

The author shared their Rust library, llmshim: a shim layer that unifies the request and response formats across different LLM providers.

It accepts a single request format, translates it to the target provider's native API, and converts the response back to a unified format. The author clarifies that it is not an agent framework: it doesn't handle tool calls, store conversation history, or reduce network latency. It currently supports OpenAI, Anthropic, Gemini, and xAI, and is available on GitHub and crates.io.
