| `--cai-chat` | Launch the web UI in chat mode with a style similar to Character.AI's. If the file `img_bot.png` or `img_bot.jpg` exists in the same folder as server.py, this image will be used as the bot's profile picture. Similarly, `img_me.png` or `img_me.jpg` will be used as your profile picture. |
| `--cpu` | Use the CPU to generate text.|
| `--load-in-8bit` | Load the model with 8-bit precision.|
| `--llama-bits` | Load LLaMA models with specified precision. 2, 3 and 4 bit are supported, use standard `--load-in-8bit` for 8bit precision. |
| `--load-in-4bit` | Load the model with 4-bit precision. Currently only works with LLaMA.|
| `--llama-bits` | Load pre-quantized models with specified precision. 2, 3, 4 and 8bit are supported. Currently only works with LLaMA. |
| `--bf16` | Load the model with bfloat16 precision. Requires NVIDIA Ampere GPU. |
| `--auto-devices` | Automatically split the model across the available GPU(s) and CPU.|
| `--disk` | If the model is too large for your GPU(s) and CPU combined, send the remaining layers to the disk. |
