I’m using Amp as my main coding agent (outside of work), and they have free mode with ads. It used to be that free mode let you used it with lower cost models like GLM, Kimi K2, etc. but recently they they switched that to a daily $10 limit but with Opus 4.5.

Was curious whether ads would cover the cost of inference, so a bit of napkin math.

They seem to display ~3 ads per minute, on tech products, presumably with pretty good signal and intent based on recent chat history. Not the most up to date on CPM but based on some basic searches we assume $30 per thousand impressions, that’s about 9c per minute and ~$5 per hour. Of course users aren’t always looking at the agent coding, but averaged out over say 3 hours of usage per day, that kinda covers the cost. The $10 per day limit is probably related to average daily session use.

On ChatGPT showing an ad per conversation with good signal and intent audiences could have pretty high CPM or CPC too, easily $0.01 to $0.10 per conversation? I think that’s easily sufficient to cover the API pricing for ChatGPT 5.2 instant or mini thinking for the majority of users queries.
