The TUI supports streaming and displaying thinking tokens with visual distinction. You can use thinking tokens to reason step-by-step before committing to a response. + +**Reasoning Models**: DeepSeek offers specialized reasoning models (e.g., `deepseek-reasoner`, `deepseek-r1`) that excel at step-by-step problem solving. Consider using these models for complex tasks. + +**Large Context Window**: DeepSeek models have 128k context windows, allowing you to process large codebases. Use `project_map` and `file_search` to navigate efficiently. + +**DeepSeek API**: The CLI uses DeepSeek's OpenAI‑compatible API with support for the Responses API endpoint. The base URL can be configured for global (`api.deepseek.com`) or China (`api.deepseeki.com`). + +**Web Browsing**: For up‑to‑date information about DeepSeek models, documentation, or API changes, use `web.run` with citations.
