+### Persistence Options
+
+By default, all chat completions are saved to the database, including both the chat thread (conversation history) and the individual API request log. 
+Use these options to control what gets saved to the database when making chat completions.
+
+#### `--nohistory`
+
+Skip saving the **chat thread** (conversation history) to the database. The individual API **request log** is still recorded.
+
+```sh
+llms "What is the capital of France?" --nohistory
+```
+
+#### `--nostore`
+
+Do not save **anything** to the database — no request log and no chat thread history. Implies `--nohistory`.
+
+```sh
+llms "What is the capital of France?" --nostore
+```
