Improve results
Try different models
Find out which models work best for different use cases in our AI models overview. You can try different models by selecting them in the model switcher.

The model selection is a spreadsheet setting. It applies to all bulk tool runs and all GPT function executions in the current spreadsheet.
Provide additional instructions
You can improve rewrite quality by providing specific instructions that help the AI more closely follow your requirements for tone, writing style, format, and other aspects.
You can define the following types of instructions for the AI:
- Custom instructions are defined for the current bulk tool run.
- Global instructions can also be defined in the spreadsheet settings and apply to all bulk tools and GPT functions in the current spreadsheet.
If both custom instructions and global instructions are defined, the AI uses both as a combined set of instructions. For consistent results, make sure both sets of instructions are aligned and do not contradict each other.
For example, set the current run to use professional language and instruct the AI to maintain technical accuracy in all runs:

Adjust the creativity level
Adjust the level of creativity (accuracy vs. freedom) the AI is allowed in rewriting content. Use a lower level to stay closer to the original text.

Creativity is a spreadsheet setting. It applies to all bulk tool runs and all GPT function executions in the current spreadsheet.
