The big idea
Each AI response burns electricity and GPU time. That's why free tiers have message limits and why pro plans exist — running these models is genuinely expensive.
Some examples
- A long GPT-4 conversation can cost the company a few dollars.
- Free tiers throttle to keep costs sustainable.
- Image generation costs more than text.
- Local open models shift cost from cash to your electric bill.
Try it!
Search 'OpenAI API pricing' and look at per-token costs. Notice how fast a long conversation could add up.
