# Set up LLM providers

Last validated Jul 20, 2026

\[Missing snippet: aperture\_release\_note.mdx]

Each provider requires API credentials and a configuration entry in the [Aperture configuration][kb-aperture-configuration]. After you configure a provider, any [LLM client set up to use Aperture][kb-use-your-tools] can access models from that provider automatically. A provider can also forward each client's own credentials to the upstream service instead of injecting a shared key. For more information, refer to [Set up passthrough mode][kb-use-passthrough-mode]. Refer to the [provider compatibility reference][kb-provider-compatibility] for the full matrix of supported providers, API formats, and compatibility flags.
