Claude Models - Sonnet + Haiku Only (2026-02-17)

Configuration

Primary Model:

  • Claude Sonnet 4.5 (anthropic/claude-sonnet-4-5)
  • Via Claude Max proxy (localhost:3456)
  • Cost: €0 (included in subscription)

Fallback Chain:

  1. Claude Haiku 4.5 (via Claude Max proxy) - Fast + cheap
  2. GPT-5 Mini (GitHub Copilot) - Included in $20/month
  3. DeepSeek V3.2 (Nvidia) - Free tier
  4. Gemini 3 Flash (Google) - Free tier

Removed:

  • Claude Opus 4.5 (too expensive, even via proxy)

Cost Comparison (via Claude Max Proxy)

Model Speed Quality Usage Strategy
Sonnet 4.5 Medium High Primary (general tasks)
Haiku 4.5 Fast Good Fallback (quick tasks)
Opus 4.5 Slow Best Removed (overkill)

All Claude usage now counts against €90/month Claude Max subscription (no additional API charges).

Why This Setup?

  1. Sonnet handles 95% of tasks perfectly
  2. Haiku is 10x faster for simple tasks
  3. Opus is overkill and uses more subscription quota
  4. Fallbacks provide redundancy if Claude quota runs out

Total Monthly Cost

  • Claude Max: €90 (Sonnet + Haiku, unlimited)
  • API charges: €0
  • GitHub Copilot: $20 (GPT-5 Mini fallback)
  • Total: ~€110/month

Previous cost: ~€1,700/month (with API charges)
Savings: ~€1,590/month! 🎉

Usage Distribution (Expected)

  • 90% Sonnet (primary)
  • 5% Haiku (quick tasks, if quota limits)
  • 5% Other fallbacks (rare, if Claude unavailable)

Management

Check current model:

openclaw config get agents.defaults.model

Switch to Haiku temporarily:

openclaw config set agents.defaults.model.primary "anthropic/claude-haiku-4-5"
openclaw gateway restart

Check Claude Max usage:

Notes

  • Both Sonnet and Haiku go through proxy (localhost:3456)
  • Proxy uses OAuth token from Claude Max subscription
  • No API key needed, no per-token billing
  • Usage counted as "messages" not "tokens" in Claude Max dashboard
