Reasoning-budget tradeoffs across Claude extended thinking and GPT-5
Both vendors let you spend more tokens on internal reasoning — when does it pay?
Creators · Model Families · ~7 min read
The premise
More thinking tokens helps on hard tasks and wastes money on easy ones — route by task difficulty.
What AI does well here
- Reserve high reasoning budgets for complex multi-step tasks
- Measure quality lift per thinking token
What AI cannot do
- Promise that more thinking always helps
- Replace evals — guess-by-feel routing burns money
Key terms in this lesson
Practice this safely
Use a small project example from your own work. The useful move is to compare the AI's draft against your goal, sources, and constraints before you trust it.
- 1Ask AI to explain extended thinking in plain language, then underline anything that sounds uncertain or too broad.
- 2Give it one detail from "Reasoning-budget tradeoffs across Claude extended thinking and GPT-5" and ask for two possible next steps plus one reason each step might be wrong.
- 3Check reasoning tokens against a trusted source, teacher, adult, expert, or original document before you use it.
