# Supported Models

> The current Claude, GPT, Gemini, and Grok model catalog available through OmniaKey

OmniaKey routes to a curated catalog from four vendors as peers — use the model
id below in any compatible SDK or coding agent. These models support tool use;
those marked **fast** are tuned for low latency. See the
[API Reference](/en/api) for how to call these ids over each protocol.
