1. The Two Plans Explained

Feature	A. Free Tier (Recommended)	B. Paid Tier
Cost	$0.00 forever.	Pay per Token (~$0.30 - $1.25 / 1M tokens).
Limits	Low "Rate Limits" (stops if too fast).	Very High limits.
The Catch	PRIVACY WARNING: Google may use your inputs/outputs to train their models.	PRIVATE: Data is NOT used for training.
Best For	Experiments, Learning, Prototypes.	Commercial apps, Sensitive data.

2. Which Models are Free?

"Flash" Models

Fast, Cheap, Efficient

·Gemini 2.5 Flash (Recommended)

·Gemini 2.0 Flash

·Gemini 1.5 Flash

"Pro" Models

Complex Reasoning, Coding

·Gemini 2.5 Pro

·Gemini 1.5 Pro

3. The Specific Limits (Speed & Quantity)

The limit depends heavily on the model you select in AIG.SetModel.

Metric	A. Flash Models (Screenshots, Text, Standard)	B. Pro Models (Deep Logic, Coding)
Requests Per Minute (RPM)	15 RPM One request every 4 seconds.	2 RPM WARNING: Only one request every 30 seconds.
Requests Per Day (RPD)	1,500	50
What happens if I go faster?	You get HTTP Error 429. The script stops or returns an error (Status 0). You are not charged money.
