| These are the VRAM and RAM requirements (in MiB) to run some examples of models **in 16-bit (default) precision**: | |

| | bloomz-7b1-p3 | 13483.1 | 4470.34 | | |
| #### GPU mode with 8-bit precision | |
| Allows you to load models that would not normally fit into your GPU. Enabled by default for 13b and 20b models in this web UI. | |
| | model | VRAM (GPU) | RAM | | |

| | gpt-neox-20b | 20384 | 2291.7 | | |
| #### CPU mode (32-bit precision) | |
| A lot slower, but does not require a GPU. | |
| On my i5-12400F, 6B models take around 10-20 seconds to respond in chat mode, and around 5 minutes to generate a 200 tokens completion. | |
