# Set up LLM providers

Last validated Sep 29, 2026

Choose a provider guide below to configure its API endpoint, credentials, and models in your [Aperture configuration][docs-aperture-configuration]. Compare API formats and requirements in [Supported providers and clients][docs-provider-compatibility] before [setting up a client][docs-use-your-tools].

To forward clients' own provider credentials, follow [Set up passthrough mode][docs-use-passthrough-mode]. You can also configure a shared key as a fallback.
