Estimate your monthly OpenClaw API bill in 60 seconds — and find out if you're overpaying.
Tip: Long-running sessions accumulate context fast. Fresh sessions = lower bills.
OpenClaw sends your messages to AI model APIs. You pay per token — roughly per word. The cost depends on your model, how long your context window is per message, and how often your agent is active.
Most users don't realize how much their context window compounds costs. A 3-week-old session carries thousands of tokens of history into every single message. Starting fresh sessions weekly can cut your bill by 40–60%.
| Model | Input (per M tokens) | Output (per M tokens) | Best for |

| Claude Sonnet 4 | $3 | $15 | Most tasks — best balance |
| Claude Haiku 3.5 | $0.80 | $4 | Fast responses, high volume |
| GPT-4o | $2.50 | $10 | OpenAI alternative to Sonnet |
| GPT-4o Mini | $0.15 | $0.60 | Budget option, basic tasks |
| Ollama (local) | $0 | $0 | Free — needs capable hardware |
