🤖Anthropic Tweaks Claude Effort Scale Without Warning
Your apps might think they're broken now
TL;DR
Anthropic updated the way Claude interprets user effort levels starting Aug 22. The change from version 2.1.237 affects how users interact with the model but was not announced publicly or documented in changelogs.
Starting August 22, Anthropic quietly adjusted how its Claude AI model reads user input efforts without warning users. This tweak could lead to unexpected behavior for apps relying on previous interpretations of effort levels. The change affects version 2.1.237 and later, where 'high' effort is now rated as 10 out of 100, previously equivalent to what was marked as 'low'. Users reported issues with their applications due to this sudden shift in how Claude processes input data.
