Most Used LLMs
This ranking highlights models with visible API usage and rank signals. It is an adoption view, not a benchmark leaderboard: a model can be widely used because it is cheap, available, fast, familiar, or bundled into developer workflows.
Quick Answer
The most used LLMs are usually models that combine availability, strong enough quality, predictable API behavior, and pricing that works for production. Usage rank should be read alongside cost, context window, latency, and whether the model fits your task.
