Financial Visibility

Exact Dollars

Clear breakdown of input prompt vs output generation savings.

The production engineering challenge

Engineering teams often struggle to forecast AI infrastructure costs and justify middleware ROI to leadership without interactive, data-backed financial modeling.

Technical architecture & mechanics

Real-world frontier model pricing sync

Synchronized with official input and output rate cards across all major cloud providers.

Workload-specific savings modeling

Simulates exact savings percentages for RAG search (58%), agent tool loops (65%), and conversational chat (48%).

Custom model rate configuration

Allows entering custom input/output prices and throughput volume for proprietary or fine-tuned models.

Calculate Savings Programmatically

import { calculateCombinedSavings, FRONTIER_MODELS } from '@/lib/tokenizer'; const opusModel = FRONTIER_MODELS.find(m => m.id === 'opus-5'); // Calculate net dollar savings on 1 Billion tokens const savings = calculateCombinedSavings( opusModel, 600_000_000, // 600M input tokens saved (60%) 140_000_000 // 140M output tokens saved (35%) ); console.log('Monthly net dollar savings: $' + savings.totalSavings);
