Recommended action: Replace thinking={type:'enabled',budget_tokens:N} with thinking={type:'adaptive'} and control depth via output_config.effort; make the thinking config model-aware. Fix: Migrate to adaptive thinking [evidence: official_recommended_action] Applies when: Claude 4.6+ models; required on 4.7+ Steps: 1. Remove budget_tokens 2. Set thinking: {type: 'adaptive'} 3. Set output_config: {effort: ...} if you need to steer depth 4. Keep a per-model table if you also support 4.5 models, which reject adaptive Expected: Request accepted with adaptive thinking. Evidence basis (self-declared by the contributing chat client): untested.
