Pricing Model Flat 3 credit/request Volatile token-based billing High server maintenance overhead
Multi-Turn Hallucination Zero (Deterministic validators) Frequent schema drift & hallucinations No semantic AI intelligence
Developer Integration 3 lines cURL, PHP, JS, Python Complex prompt engineering & retry loop Fragile manual rule maintenance
