Why generic token calculators leave engineering teams blindsided.
Reasoning Token Inflation
Reasoning models like OpenAI o1/o3-mini and Claude 3.7 generate invisible internal 'thinking tokens'. Because they are billed at high output rates, costs often triple without warning.
Evaluator Loops & Retries
When a guardrail or critic rejects an answer 25% of the time, standard calculations fail. Our finite geometric series models the true compounded request execution cost.
Prompt Caching Nuances
Anthropic charges a 25% surcharge to write to 5-minute ephemeral cache, while OpenAI provides a 50% discount on cache reads. We model provider-specific amortized reuse.
Configure → Simulate → Compare
Define Component Pipeline
Chain intent routers, embedding retrieval, agent reasoning calls, and evaluators into an ordered execution graph without code.
Model Traffic Growth
Stress-test Conservative (500 DAU), Expected (5k DAU), and Aggressive (25k DAU) scenarios with peak concurrency multipliers.
