Why LLM Costs Spiral Silently—and How Real-Time Monitoring Stops It

The frictionless nature of LLM API calls—where every iteration carries a cost but no immediate financial consequence—creates a new class of billing surprises developers haven't encountered before.

As adoption grows, this transparency gap poses both a user satisfaction and trust issue for AI platforms.
