Thanks for this hint. There used to be a free $5 API credit after signing up & verifying your phone number. But it seems this offer is gone. We will update our documentation accordingly.
As a cost benchmark, the Anthropic API cost of running the above four demo macros is 0.02 US$:
Is the benefit worth the cost? This certainly strongly depends on your RPA use case. Our medium term goal is to use local LLMs like Llama or Mistral - just like we already include local and free computer vision and OCR options. But as of today, these local LLMs are not good enough yet for computer use automation.
As a rule of thumb, we recommend to use local automation whenever possible. It is faster and free. However, the new AI commands allow you to automate tasks that where not (easily) automatable before. For example, you can use them to overcome a certain tricky part of the automation (e. g. finding & clicking a confirmation dialog that changes position, text, shape and color), and then continue with the local automation.
