Models and Reasoning
Sets the reasoning level new chats start with. Location: Settings > General > Default working mode.
| Mode | Effect | When to choose it |
|---|---|---|
| Everyday use | Starts with reasoning turned off. | Everyday work where fast answers come first |
| Demanding tasks | Starts with the highest reasoning. | Coding, analysis, and multi-step work |
| Manual (default) | Uses the last selected reasoning level. | When you want to pick the level for each job yourself |
- The default mode only sets the level new chats start with; during a chat, you can change the level from the composer at any time (see Reasoning levels).
- Your choice is stored in your account and applied the same way on Web, Mobile, and Desktop (see Settings Reference).
- Demanding tasks means longer thinking and more credit usage; for everyday work, Everyday use or Manual is more economical.
Example scenario
If you mostly ask short questions during the day but code a few times a week, choose Everyday use and raise the level from the composer in the chats where you code. If you mostly do analysis and coding, Demanding tasks starts every new chat at the highest level.
