What do the LLM price alerts cover?
Price changes and dated price announcements for the OpenAI, Anthropic and Google models in AiGanak's pricing table: standard, cached, batch and long-prompt rates. Each alert gives the old and new price, the date and the effect on a typical monthly bill.
How often will I get an email?
Only when a price changes or a dated change is announced. AiGanak checks the providers' pricing pages every week, so most months bring a few alerts at most, and some bring none.
Is it free, and can I stop it?
It is free. Every alert has a one-click unsubscribe link, and your email address is used for nothing else.
