+#### 3a. Reuse an Existing Model with `extends`
+
+For wrapper providers that mirror a model from another provider, prefer reusing the canonical model definition instead of duplicating the whole file.
+
+Use `extends` only for non-first-party wrappers and mirrors. Do not use it inside the actual lab provider directories that act as the canonical source for a model family, for example `providers/anthropic/`, `providers/openai/`, `providers/google/`, `providers/xai/`, `providers/minimax/`, or `providers/moonshot/`.
+
+```toml
+[extends]
+from = "anthropic/claude-opus-4-6"
+omit = ["experimental.modes.fast"]
+
+[provider]
+npm = "@ai-sdk/anthropic"
+```
+
+Rules:
+
+- `from` must point to another model using `<provider>/<model-id>`.
+- `omit` is optional and removes fields after the inherited model and local overrides are merged.
+- You can override any top-level model field locally.
+- If you override a nested table like `[cost]`, `[limit]`, or `[modalities]`, include the full values needed for that table.
+- `id` still comes from the filename; do not add it to the TOML.
+
+Use `extends` when the wrapper model is materially the same as the source model and only differs by a small set of overrides or omitted fields.

+When converting existing wrapper models to `extends`, compare generated output before and after the change:

+```bash

+
+This prints a diff for each changed model TOML so you can confirm the generated JSON only changed where you intended.
