AI API bills are predictable once you know three numbers: tokens in, tokens out and requests per month. The surprises come from choosing a frontier model by habit, oversized prompts, and the human time behind a “fully automated” bot. These guides and calculators put dollar figures on support bots, RAG, embeddings and product copy at 2026 list prices.
If you only do one thing: measure your average tokens per request, then price it in the GPT vs Claude vs Gemini cost calculator. Start on the cheapest model that passes your tests and route only the hard requests up.
