What does it really cost to run AI?
Model APIs quote a token price. Production bills include speech, telephony, vector databases, retries, evals and human review — LLM inference is often only 15–35% of the total. These calculators do the math on all of it. Free, no signup.
🧮 AI Project Total CostThe full stack: inference + voice + images + vector DB + overhead. Start here.
📞 Voice Agent CostSTT + LLM + TTS + telephony, per call and per month.
✉️ AI SDR CostResearch + personalization + verification, per lead.
📚 RAG Pipeline CostOne-time embedding + per-query inference + vector DB.
💬 Chatbot CostSupport or product assistant, per conversation.
🎓 Fine-tuning CostTraining tokens × epochs + serving cost after launch.
🖼️ Image API CostGeneration at scale, per campaign and per month.
🧷 Embedding CostIndexing and refresh cost for any corpus size.
Why trust the numbers?
Every model price on this site is pulled daily, automatically from OpenRouter's public pricing API and rendered into the calculators as-is — no hand-maintained tables. Rates that aren't per-token (speech, telephony, vector DB) are editable inputs with the source and date stated next to them. Our method page shows every formula. If a number can't be sourced, it isn't shown.
