Error message

providers.{key} conflicts with built-in provider {spec.name!r}; use the built-in provider key or choose a different custom provider name

What it means

In ProvidersConfig.convert_extra_providers, an extra (custom) provider key collides with a built-in provider registered in the registry (find_by_name matched). Extra fields become custom providers, so a name equal to a built-in one (e.g. "anthropic") is ambiguous and rejected; the input at fault is the conflicting providers.<key> entry.

Solutions

1. Configure the built-in provider under its own key instead of as an extra field
2. Rename the custom provider to a unique name
3. Remove the duplicate entry if it was accidentally added
