Setting a Custom Price for a Model in AgentsView
Original: Setting a custom price for a model in AgentsView
Simon Willison shares how to add a custom model price in AgentsView after Claude Fable 5 launched before its pricing data was added.
AgentsView, built by Wes McKinney, visualizes token usage and costs across local coding agents. When Claude Fable 5 launched without being listed in AgentsView's pricing database, Simon Willison used Fable itself to reverse-engineer the tool and find a recipe for setting custom prices. He also shared a treemap showing over $83 in single-day Fable 5 spending and $516 saved via prompt caching.
This article is part of Simon Wilison's "Today's Lessons (TIL)" series, focusing on how to manually set custom prices for new models not yet included in the AgentsView tool.
