The same AI model can cost 6x more depending on where you buy it. ATOM tracks 50+ vendors weekly and publishes the AIPI every Monday. Three products: ATOM MCP (works natively in Claude and Cursor), ATOM Terminal for analysts and FinOps teams, and ATOM Feed for enterprise data licensing. Know what inference actually costs.

Hey Product Hunt. Stamos here, co-founder of ATOM. We built this after watching too many teams get blindsided by their inference bills. The same model costs 16x more depending on where you buy it. Output tokens run 3.84x more than input on average. Nobody talks about this until the bill arrives. We spent a year building a real index for inference pricing. Not a scraper. A chained matched model methodology borrowed from commodity price indexing. 2,583 SKUs, 47 vendors, 6 modalities, published every Monday. ATOM MCP is free to try today and works natively in Claude, Cursor and Windsurf. Search ATOM on any MCP marketplace and you are in. Ask me anything about the data, the methodology, or what we are seeing in the market right now.

Week 12 AIPI data is live. The number that surprised us most this week: buying inference direct from a model developer costs 7x more per input token than buying the same model through a third-party platform. The output gap is 5.2x. Most developers never compare because they pick a vendor early and stick with it. We track 2,614 SKUs across 47 vendors weekly.
