Up to 10x credits • Uses tools to gather information, perform calculations, or execute tasks. Most powerful option.Best for: Complex queries requiring external data or tools
Up to 2x credits • Breaks problems into smaller steps with sources for each part, improving transparency.Best for: Educational content, troubleshooting, explanations
Up to 5x credits • Cycles through thinking and reflecting to refine answers progressively.Best for: Complex analysis, strategic planning, research

Troubleshooting

Cause: Research & Tools (10x) and Deep Thinking (5x) modes multiply credit costsSolutions:
  • Use Quick mode (standard) for simple queries
  • Use Auto mode to let Claude optimize automatically
  • Reserve deep modes for complex tasks only
  • Monitor credit usage in dashboard
Cause: Deep Thinking mode or Extended Thinking models are slowerSolutions:
  • Use Claude Haiku 4.5 for faster responses
  • Use Quick mode (standard reasoning)
  • Add “thinking…” indicators for user feedback
  • Reserve slow modes for async tasks
Rare: Claude’s 200K context handles most use casesSolutions:
  • Implement message history pruning
  • Summarize older messages
  • Use streaming for very long outputs
