GLM Coding Plan alternative: OpenScale Unlimited
Last updated: Nov 4, 2026
The short answer
The GLM Coding Plan is a subscription from Z.ai, the maker of GLM, for its GLM models inside supported coding tools. OpenScale Unlimited is a flat monthly plan for your coding agents: unlimited tokens on DeepSeek V4.1 Flash and GLM 5.3 Flash, with no 5-hour window and no weekly limit. Plans start at $29 a month, and the first week is $5.

Which one fits
The GLM Coding Plan includes GLM-5.3, which OpenScale does not serve. If you want GLM-5.3 itself, it is the plan to pick.
If your agents run all day and reach the 5-hour or weekly limits, OpenScale Unlimited has neither: you choose how many agents run at once, and they keep going.
OpenScale Unlimited plans
- Lite: 1 agent at once, $29 a month, first week $5
- Plus: 2 agents at once, $79 a month, first week $13
- Pro: 4 agents at once, $159 a month, first week $27
- Crew: 6 agents at once, $239 a month, first week $40
- Fleet: 10 agents at once, $399 a month, first week $67
Every plan has unlimited tokens on DeepSeek V4.1 Flash and GLM 5.3 Flash. Extra agent slots on Plus and larger plans are best effort: they open when there is room and are not guaranteed. See the plans.
Questions
- Is there a token limit on OpenScale Unlimited?
- No. DeepSeek V4.1 Flash and GLM 5.3 Flash have no token cap and no meter, all month. Other models and fast mode are pay as you go from your balance.
- What is the difference between the plans?
- Only how many agents run at once, from 1 on Lite to 10 on Fleet.
- What are extra agent slots?
- On Plus and larger plans, agents beyond your plan can run in extra agent slots. They are best effort: they open when there is room and are not guaranteed.
- Which coding agents work with it?
- Any agent that speaks the OpenAI Chat Completions or Responses API or the Anthropic Messages API, such as Claude Code, Codex, OpenCode, Cline and Kilo Code. A plan comes with its own API keys.
- Can I use a plan for an app that serves users?
- No. Plans are for your own and your team’s coding agents while you build. Apps, batch jobs and reselling fit pay as you go, billed per token.
