LM15, one front door for model APIs
An SDK and playground that give developers one request-and-response interface for model providers including OpenAI, Anthropic, Gemini, and others.
Field notes
The homepage exposes a typed request pattern built around LMRouter, Message, and Request, with the model selected using a provider:model identifier. Its method map extends beyond chat to images and video, generation jobs, live voice, files, and batches, while the benchmark panel records package size, dependency footprint, import time, and post-import memory. The page links to documentation, a playground, GitHub, privacy and licenses, and a shared contract.
