Calculators
Workload-based, not price-sheet math: they model resent context, cache TTLs and retries.
API Cost Calculator Any workload compared across all 232 models, with caching and batch discounts. Chatbot Cost Simulates real conversations — growing history, resent context, per-provider cache TTLs. Agent Cost Multi-step loops, tool schemas, retries — why agents cost 10–30× more than naive math says. RAG Cost Indexing, retrieval and generation priced separately. Embeddings are the cheap part. Voice AI Cost STT + LLM + TTS per minute, per call, per month — the full three-part bill. GPU Rental Pricing H100, A100, RTX 4090 across 10 providers — the same chip at a 5× price spread. Image API Pricing $0.003 to $0.17 per image — three market tiers and a batch calculator. Token Counter Paste text, get tokens and cost on any model. Runs entirely in your browser. Cost-Cutting Guides The five levers that cut an LLM bill 80% — routing, caching, batch and more, ranked.
How AI API pricing works — the 60-second version
Every major AI provider bills the same way: you pay per token (roughly ¾ of a word), with separate rates for input (what you send) and output (what the model writes back). Output is usually 3–5× more expensive than input. A model listed at $5 / $25 per million tokens costs $5 for every million tokens you send and $25 for every million it generates.
Two discounts change the math dramatically: prompt caching cuts repeated input costs by up to 90% (critical for chatbots that resend conversation history), and batch processing takes ~50% off when you can wait for results. Our calculators account for both — most "how much will this cost" articles don't, which is why their estimates run 2–3× too high or too low.
