Reading tip: skim the summary first, then the tables and FAQ, then use the next-step cards below.

One-line answer

Configuration changes are often the fastest way to cut OpenClaw costs: shrink context, cap output, lower thinking when possible, and enable caching for repeated prompts.

TL;DR

  • Lower maxTokens before changing vendors.
  • Not every task needs a big context window.
  • High thinking should be reserved for hard reasoning.
  • Caching and session cleanup reduce silent token waste.

Five config levers worth changing first

1. Right-size the context window

ScenarioSuggested window
simple Q&A4K
code review8K-16K
long-doc analysis32K+ only when needed

2. Cap output length

{
  "maxTokens": 500
}

3. Avoid maximum thinking by default

loweveryday requests
mediumcoding and analysis
highdifficult reasoning only

4. Trim prompts

Remove repeated framing, unnecessary politeness, and irrelevant history.

5. Enable caching and reset sessions

High-reuse workflows benefit from caching, and long-running sessions should be refreshed before they become bloated.

Example config

{
  "agents": {
    "defaults": {
      "model": "sonnet",
      "maxTokens": 500,
      "contextWindow": 8192,
      "thinking": "low",
      "clearHistoryAfter": "24h"
    }
  },
  "cache": {
    "enabled": true,
    "prefix": "session:"
  }
}

Quote-ready takeaway

If you have not done any cost governance yet, start by tightening maxTokens, shrinking context, reducing thinking intensity, and evaluating caching before you change models.

FAQ

Should I optimize configuration before switching models?

Yes in most cases, because defaults often waste more tokens than users realize.

Why do long sessions become expensive?

Because the model keeps re-reading history, so the input bill quietly grows over time.

Is high thinking always better?

No. It is useful for difficult reasoning, not for every request.
