## Available Anthropic Models [#available-anthropic-models]

that you cannot find in **Jan**, follow instructions in [Add Cloud Models](/desktop/manage-models#cloud-models):
- See list of available models in [Anthropic Models](https://docs.anthropic.com/claude/docs/models-overview).
- The `id` property must match the model name in the list. For example, `claude-opus-4-20250514`, `claude-sonnet-4-20250514`, or `claude-3-5-haiku-20241022`.
