AI chat price comparison

Most AI chat tools charge a fixed monthly subscription whether you use them or not. OpenFastChat charges close to the underlying Groq inference cost and shows the exact price after every reply, so light users pay very little and heavy users stay in control with an optional monthly compute cap.
