Claude Code deep research used tokens extremely fast
Claude Code was being used on a large project when `/` made token use jump from about 36,000 tokens to 867,000 tokens in less than 30 seconds. Regular Claude Code runs had sometimes used around one million tokens before, but this felt different because the increase was so fast. The run quickly hit the .
The main question is whether this is normal behavior for or a sign of a problem. can use far more context and investigation than a normal coding chat, so very fast token use is possible.
Key points
- Claude Code’s `/` command caused a very fast token increase.
- Token use rose from about 36,000 to 867,000 in under 30 seconds.
- The run hit soon after.
- Large can make much more expensive than a normal coding exchange.
