318318A discovered ID doesn't get its own row when it matches a row already in the picker:
319319 
320320* Same ID: the discovered ID exactly matches an existing row's ID, or the two IDs are spellings of the same [Fable](/docs/en/model-config#work-with-fable) version.
321* Same model as a built-in alias: when a discovered explicit ID names the model that a built-in alias currently resolves to, the picker shows only the alias row. For example, while `sonnet` resolves to `claude-sonnet-5-5`, a discovered `claude-sonnet-5-5` collapses into the `sonnet` row, and a discovered `claude-sonnet-5` still gets its own row. Before v2.1.197, Claude Code didn't fold these IDs into built-in rows, so the ID an alias resolved to also got its own "From gateway" row.

323323Results are cached to `~/.claude/cache/gateway-models.json`, or `%USERPROFILE%\.claude\cache\gateway-models.json` on Windows, and refreshed on each startup. If you set [`CLAUDE_CONFIG_DIR`](/docs/en/env-vars), the cache lives under that directory instead. If the request fails or the gateway doesn't implement `/v1/models`, the picker falls back to the cached list from the previous startup or to the built-in model list. If your gateway serves Claude models under aliases that don't match the discovery filter, developers can add those aliases manually with the [model configuration](/docs/en/model-config) variables.
