Why a 5-Minute Claude Code Session Can Cost a Dollar
Agents loop, and every loop iteration uses tokens — that's why agentic costs add up faster than chats.

The big idea
A regular ChatGPT message costs maybe a fraction of a cent. A 5-minute Claude Code or Manus session can cost a dollar — sometimes more. Why? Agents loop, and every loop re-sends the whole conversation plus the tool outputs. After 30 iterations, you're sending 50,000 tokens per turn. Costs sneak up.
Some examples
Claude Code on Sonnet runs for 8 minutes on a refactor — your dashboard shows $1.40.
A Manus task scraping 20 pages costs $0.60 — most of it is re-reading prior steps.
Cursor Agent fixing 200 lint errors costs $0.30 — small per-fix, big in total.
An OpenAI Operator 10-minute web task costs $2 — it took 25 vision-model screenshots.
Try it!
After your next agent run, find the cost in your dashboard. Was it worth it? Would Haiku or GPT-mini have done the job?
