How Much Does OpenClaw Cost? API Pricing & Cost Optimization (2026)
OpenClaw itself is free. The cost comes from the AI models it uses. Here's what you'll actually pay based on real usage data, plus how to cut that bill dramatically.
Real Monthly Costs by Usage Level
Light use (10-20 tasks/day): $10-30/month with Claude Sonnet.
Moderate use (50-100 tasks/day): $50-150/month.
Heavy use (always-on agents): $200-500+/month.
Budget setup (DeepSeek primary): $2-8/month for the same light use.
Model Pricing Comparison
Claude Opus 4.6: $5/$25 per million tokens (input/output) — premium, use for complex coding.
Claude Sonnet 4.6: $3/$15 per million tokens — the sweet spot for most users.
GPT-5-mini: ~$1/$4 per million tokens — good budget OpenAI option.
Gemini 2.0 Flash: Free tier available, then ~$0.10/$0.40 per million tokens.
DeepSeek V3: $0.28/$0.42 per million tokens — 10x cheaper than Claude Sonnet.
Ollama (local): $0 — free but requires 16GB+ RAM and weaker performance.
Optimization 1: Add DeepSeek as Budget Fallback
Route routine tasks (reminders, simple lookups, file management) through DeepSeek while keeping Claude for complex work. This alone can cut costs by 60-80%.

Optimization 2: Reduce Context Window
The default context can be 128k-200k tokens. Most conversations work fine at 50k — cutting your per-request token usage by 75%:
openclaw config set agents.defaults.contextTokens 50000 openclaw gateway restart
Optimization 3: Start Fresh Conversations
Long conversations accumulate tokens. Send /new in Telegram when switching topics to reset the context window.
Optimization 4: Multi-Key Rotation
Multiple API keys per provider means you can spread usage across multiple billing accounts or take advantage of free-tier allocations from each key. Our complete guide covers the full multi-key rotation setup.
The Optimal Budget Setup
For the lowest possible cost without sacrificing quality on important tasks: set Claude Sonnet 4.6 as primary (handles complex work), add DeepSeek and Gemini Flash as fallbacks (handles routine tasks cheaply), reduce context to 50k tokens, and use /new frequently. Expected cost: $8-15/month for moderate daily use.
Frequently Asked Questions
The software is free. API costs depend on usage: light use with Claude Sonnet costs $10-30/month. With DeepSeek as a budget fallback and context optimization, you can reduce this to $8-15/month.
Use DeepSeek V3 as your primary model ($0.28/M tokens) with Gemini Flash free tier as fallback. Reduce context to 50k tokens. Expected cost: $2-8/month for light-moderate use.
You can use Ollama for local models at zero API cost, but this requires 16GB+ RAM and performance is significantly weaker than cloud models. Google Gemini also offers a free tier for limited usage.
Three key optimizations: add DeepSeek as a budget fallback model, reduce context tokens to 50k, and use /new in chat when switching topics to reset context. Together these cut costs by 50-75%.
