Freemium AI

Freemium is not a new idea, but AI changes the economics in an important way: every free user costs real money in compute. Traditional SaaS can afford a generous free tier because marginal serving cost is trivial. With AI, every query burns tokens. The question is whether the conversion lift from a free tier outweighs the inference spend on users who never upgrade.

Products like ChatGPT, Perplexity, and many coding tools use this model, gating the most powerful or high-volume features behind paid tiers. The free experience is a product demo and a habit loop. If users hit a capability wall just when they're most engaged, they upgrade. If the free tier is too generous, they never feel the pressure to pay.

For builders launching new AI products, the math is unforgiving if free-to-paid conversion falls below two to three percent. A common refinement is time-limiting the free tier, or offering full features for a trial period rather than permanently hobbled access, which gives users a taste of the full product before asking for a credit card.
