The Advantage of Gemini 1.5 Pro in Zapier

Gemini 1.5 Pro features a massive context window, allowing you to upload long brand reference documents or complex website scripts for auditing without worrying about token limits.

Cost-Saving Tips

Using the Gemini API in Google AI Studio currently offers a 'free to use' tier with very generous rate limits, making it an excellent alternative to the paid OpenAI GPT-4.

Ensuring Consistent Behavior

Always use specific 'Instructions'. If the AI starts to drift, update your instructions with the desired output format, for example: 'Always output the audit in Markdown format'.
