Anthropic Reportedly Removes Thinking Expandable Block from Claude UI

r/ClaudeAI·low signal

A 68-upvote r/ClaudeAI post reports that Anthropic has removed the expandable thinking block from Claude's interface, with a screenshot showing the change. The 10-comment discussion is split between users who valued seeing the model's reasoning process and those who found it distracting. For builders using Claude's extended thinking feature, this UI change may indicate a shift in how Anthropic wants users to interact with chain-of-thought reasoning — the API still exposes thinking tokens, but the consumer product is hiding them.
