r/SaaS argues AI inference is killing free trials

Free trials no longer pencil out once inference sets the cost floor, one founder argues in a post on r/SaaS. The reasoning: a free user can now cost 10 to 100 times more to serve than before large language models did the work. That flips the math that free-to-paid conversion has always run on.

Freemium assumed a free user cost you almost nothing until they converted. Inference breaks that assumption.

That's one builder's reasoning on a forum, not a study across companies, so read the multiplier as directional, not measured. It does track a shift already underway in software pricing, away from flat tiers toward usage-based and per-outcome plans. You pay for what the model does, not for access to it.

I've watched builders skip that math and find out later that their own growth was the expense that got them, not competitors. I'd run the per-user cost against expected free-tier volume before flipping a free tier on, not after the invoice explains it.
