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.
