After Anthropic’s third-party tool restrictions priced agentic users off Claude Opus 4.6, the cheapest working OpenClaw stack is Z.ai’s $18/mo GLM 5 Turbo plan, with Ollama-cloud’s $20/mo GLM 5.1 and MiniMax’s $40/mo highspeed tier as the next two rungs. Kimi 2.6 stays API-only because local deployment needs roughly 750 GB of RAM.
Key Takeaways
- Z.ai’s $18/mo plan running GLM 5 Turbo is the cheapest OpenClaw backend that actually works.
- MiniMax highspeed at $40/mo handles heavier workloads without the four-figure surprise bills.
- Kimi 2.6 needs around 750 GB of RAM to self-host, so almost everyone runs it through the API.
- Keep Claude on the planner role; route scheduled jobs to the cheap backends.
- China-hosted models trade dollars for privacy on iMessage, contacts, and email skills.
Why $1,500/mo Opus Bills Pushed Users to GLM
The pressure here is simple. The moment Anthropic’s third-party tool restrictions kicked in, OpenClaw users who had been running on the Claude Pro CLI got nudged onto pay-per-token API access. At Opus 4.6 list pricing of $15 per million input tokens and $75 per million output tokens, agentic loops add up fast. The OP of the r/openclaw PSA thread tracked his own bill at roughly $1,500/mo before he switched. That figure is the reference point most cost-comparison threads on the sub now cite.
