AI Cost Guides
The calculators tell you what a workload costs; these guides tell you how to make that number smaller — or how to charge for it. Every guide uses the same live pricing data as the rest of the site (updated 2026-08-23), so the math stays honest as prices move.
How LLM API Pricing Actually Works
The four meters on every bill — input, output, cached, batch — with live prices, and the context-resend trap that makes chat apps cost 3–5× the naive estimate.
Start hereHow to Cut Your LLM API Bill
The five levers that reduce an LLM bill by up to 80% — model routing, prompt caching, batching, output control, and context discipline — ranked by effort vs impact.
Data reportAI API Price Trends: What the Tracker Recorded
Computed from our daily price snapshots: how much of the market repriced, the biggest cuts on record, and whether "prices only fall" survives the data.
RankingThe Cheapest LLM APIs in 2026
Every text model ranked by live blended price: the absolute floor, the cheapest way into each vendor ecosystem, and what "cheap" costs you in production.
FundamentalsWhat a 1M-Token Context Window Actually Costs
Live fill costs for the biggest-context models, the refill-every-turn multiplier, and the honest long-context vs RAG math.
ComparisonGPT vs Claude vs Gemini: Production Cost Comparison
What the three big families actually cost on real workloads, tier by tier, with live prices — not the marketing table.
OptimizationPrompt Caching Explained
How cached-input pricing works per provider, the TTL cliffs that silently kill your hit rate, and when caching pays for itself.
OptimizationBatch API: the 50% Discount Most Teams Ignore
Which providers offer batch discounts, what latency you trade for them, and which workloads should always run through batch.
InfrastructureSelf-Hosting vs API: the Real Break-Even Math
Live GPU rental prices vs live API prices, the utilization trap, hidden ops costs, and a 5-line break-even check for your workload.
InfrastructureH100 vs A100 vs L40S vs RTX 4090: Cost per Token
The cheapest GPU per hour is rarely the cheapest per token — throughput-adjusted economics across the popular rental cards.
PricingHow Much Does an AI Chatbot Cost to Run?
Cost per conversation and per month at three honest sizes, on live prices — plus the history-resend mechanic that quietly inflates real bills past naive estimates.
PricingHow to Price an AI Voice Agent
The full STT + LLM + TTS per-minute bill, the hidden 20–30%, and how builders turn cost per minute into a client price.
How these guides are written
Each guide is grounded in the live pricing dataset behind our 301 model pages and calculators — when a guide quotes a price, it is computed at build time from current rates, not pasted in and forgotten. Worked examples use realistic workload assumptions that are stated inline, and every recommendation includes the trade-off it costs you. Spotted something outdated or wrong?
