| Some models I'd like to use are missing.                  | <p>Contact your workspace admin. <br>Depending on organization, your admin customizes the list of models the company uses. </p>                                           |
| Models are giving outdated information.                   | Some models have knowledge cut off at a specific date (not controlled by nexos.ai). We recommend enriching the input command with "web search" or choosing a newer model. |
| I get "Model unavailable. Please try again later." error. | In most cases - downtime from service providers, in this case we recommend switching models and coming back later.                                                        |
| File does not upload. I get an error.                     | Although we support nearly all file types, some files, like TIFF, may not be supported.                                                                                   |
