The live market for AI.
PowerfulBot lists model prices, consumer plan prices and published scores, and names the page or dataset each figure came from.
The site is free to read. There is no chatbot, no model router and no paid checkout on this index. A watchlist stays in your browser. Email alerts are a double opt-in request, and the mail sender is off until an email service is approved.
Prices come from the seller’s page or from models.dev (MIT), with ModelPriceWatch (CC-BY-4.0) for settled list-price moves. Human-preference ratings come from the LMArena dataset (CC-BY-4.0). Capability scores come from Epoch AI (CC-BY-4.0) and LiveBench. Vendor-reported scores stay marked as vendor-reported. We do not fill a missing number.
How a score gets onto a board is written up in the methodology. Common questions are on the FAQ.
