Why TokenCost Lab?

In 2026, building AI applications is easy, but auditing AI infrastructure costs is a black box. Vendors race to the bottom with pricing, third-party hosting channels merge and match rates, and dark patterns like hidden prompt caching thresholds or reasoning token markups make your monthly API invoice an unpredictable puzzle.

TokenCost Lab was born out of pure engineering frustration. It is a high-fidelity, zero-bullshit designed for AI architects and indie hackers who want to know exactly what they are paying for—down to a single million tokens.

Automated, Clean Data.

We don't do static guesses. Our core engine relies on an automated pipeline that regularly aggregates, normalizes, and validates rate cards from official vendors (OpenAI, Anthropic, Gemini), developer routers (OpenRouter), and hyper-growth hosting infrastructures (SiliconFlow). We enforce strict casing rules, eliminate duplicate placeholders, and mathematically intercept edge-case routing traps before rendering them onto your dashboard.

Built for Geeks, by Geeks.

This project is built upon an open-source data architecture. If you notice a pricing discrepancy, a missing niche model, or a broken cache modifier logic, please send your feedback to [email protected], and let's keep the calculator honest.

Keeping the Servers Running.

TokenCost Lab is completely free, to cover hosting overhead and maintenance efforts, maybe someday some outbound router links contain referral tags (Affiliate codes). We strictly commit to neutrality: our recommendation algorithms (like the ROI Mode alternative switcher) are driven purely by math, code efficiency, and raw dollar performance—never by referral payouts.

Disclaimer & Fair Use.

TokenCost Lab is a simulation and auditing playground. While our automated pipelines fetch and normalize rate cards diligently, LLM provider pricing, prompt caching models, and routing strategies change dynamically in the wild.

All computed results from our simulators are high-fidelity estimates, not binding binding invoices. Always cross-verify final production parameters with your respective direct vendors before deploying standard enterprise budget lines. We are not liable for any discrepancies on your actual cloud API bills.

Zero-Data Privacy Statement

We don't want your data. TokenCost Lab is a 100% static client-side application. We do not implement user accounts, tracking databases, or cloud storage for your token parameters. Your simulation inputs never leave your browser.

To understand global traffic, we utilize Cloudflare's privacy-first, cookie-less web analytics. When you click an external vendor or router link containing a referral code, that respective third-party platform may deploy standard affiliate tracking cookies to attribute the referral. Beyond that, your privacy remains strictly yours.
