Claude 4.6 Adaptive Thinking: Reddit User Reports Token Waste and Provides Disable Commands
Adaptive Thinking in Claude 4.6
Claude 4.6 models introduce adaptive thinking, where the model self-calibrates how much reasoning to invest based on task complexity. Simple tasks get fast responses, while complex tasks trigger deeper thinking.
Reported Issues in Claude Code
According to the Reddit post, in Claude Code, extended thinking fires between every tool call. For iterative coding workflows like quick edits, lint fixes, and short back-and-forth exchanges, the added latency is noticeable. The user reports sometimes seeing it burn tens of thousands of expensive output tokens just thinking, often in thought loops without making useful progress.
Shell Commands to Control Adaptive Thinking
The source provides these bash commands for your shell profile:
export MAX_THINKING_TOKENS=$((1024*3))
export CLAUDE_CODE_DISABLE_ADAPTIVE_THINKING=1MAX_THINKING_TOKENS caps the reasoning budget to 3072 tokens per turn. CLAUDE_CODE_DISABLE_ADAPTIVE_THINKING stops Claude Code from triggering extended thinking automatically.
The user states that from their experience, adaptive thinking feels like a waste of session limits, and 2-8k of thinking tokens is usually sufficient. They invite discussion from users who find adaptive thinking useful for accomplishing tasks that couldn't be done without it.
