DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Custom Model Picker via Environment Variables

What

Administrators can inject a custom model option into the model picker via environment variables, useful for enterprise deployments with custom-routed models.

Usage
export ANTHROPIC_CUSTOM_MODEL_OPTION="my-custom-model-id"
export ANTHROPIC_CUSTOM_MODEL_OPTION_NAME="My Custom Model"
export ANTHROPIC_CUSTOM_MODEL_OPTION_DESCRIPTION="Custom routed model for our org"
Details
  • The custom model appears as an additional option in the model selection UI
  • If no name is provided, the model ID is used as the label
  • If no description is provided, defaults to Custom model ({id})
Evidence

Model picker injection (search for "ANTHROPIC_CUSTOM_MODEL_OPTION")

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
