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.

Enterprise Model Allowlist

What

Administrators can restrict which models users can select.

Usage

Configure in managed settings:

{
  "availableModels": ["opus", "sonnet-4"]
}
Details
  • Accepts family aliases ("opus" allows any opus version)
  • Accepts version prefixes ("opus-4-5" allows only that version)
  • Accepts full model IDs
  • Empty array restricts to default model only
  • Clear error messages when restricted: "Model 'X' is not available. Your organization restricts model selection."
Evidence

Model allowlist setting (search for "Allowlist of models that users can select", "restricts model selection")

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