Providers

Each provider is reached through its own llm · client binding. Add one client per provider or deployment, and point routes on llm · proxy at it.

Connecting to a Provider

exit: sys:http_client connects over HTTP, or over TLS when the server URL is https://, trusting the standard certificate authorities and using the URL's host for SNI:

openai_llm_client:
  type: llm
  kind: client
  options:
    dialect: openai
    server: https://api.openai.com
  exit: sys:http_client

To control the connection yourself, exit to your own http · client, tls · client, and tcp · client bindings instead. An AWS Bedrock client always connects this way, with the Bedrock host set on the tls · client and tcp · client.
