Free tiers help developers try AI products, but LLM usage creates real variable cost. A good free tier encourages activation without inviting abuse.
Free tier controls
Use:
- monthly credits
- rate limits
- lower-cost models
- output length limits
- no premium models
- abuse detection
- verified accounts
Show usage
Users should see remaining credits and understand what consumes them.
Upgrade path
The free tier should lead naturally to paid plans: higher quotas, premium models, better support, and team features.
Final thoughts
AI free tiers need careful cost controls. Make them generous enough to test, but bounded enough to protect margin.
