Fiorino.AI

As LLM cost management tools go, Fiorino. AI is one of the few that is open source, so you can change the code and run it your way.

AI is a cost management platform for SaaS businesses built on large language models.

It tracks what each LLM call costs and which user is driving it.

It connects to any LLM provider through an API and reports granular usage metrics, so you can see where spend goes instead of guessing from a provider invoice.

Billing is the other half.

You can set custom pricing and usage-based billing for your own customers, and multi-tenant support covers agencies and enterprises that run several clients under one setup.

User tracking is anonymous, which suits teams that care about privacy.

AI needs initial setup and configuration, and a full integration may take real development effort.

Usage Limits and an AI Cost Analyst are still on the roadmap, so do not plan around them yet.

Pricing is enterprise, so expect to talk to the team rather than sign up with a card.
