FAQ
Is GLM Coding Plan really as good as Claude Code?
On pure benchmark numbers GLM-5.1 reaches roughly 94% of Claude Opus 4.6 and edges Sonnet 4.6 on several public tests. In everyday coding work — small features, bug fixes, unit tests — the gap is effectively invisible. Heavy agentic refactors still favour Opus.
Can GLM Coding Plan really run inside Claude Code CLI?
Yes. Z.ai ships an Anthropic-compatible endpoint. Set ANTHROPIC_BASE_URL to https://open.bigmodel.cn/api/anthropic and ANTHROPIC_API_KEY to your Z.ai key — no other changes. Cline and OpenCode work the same way.
Should I start with GLM Lite or GLM Pro?
Lite at $10 is enough for one focused coding session per day and still undercuts Claude Code Pro at $20. The moment you open a second terminal or run sub-agent workflows, Pro's triple quota at $30 pays for itself. Upgrading is instant — no proration grief.
Does GLM Coding Plan work outside China?
Yes. Z.ai maintains both mainland (bigmodel.cn) and overseas (z.ai) endpoints with the same subscription. Overseas billing is in USD, mainland in CNY, and a single account can use either.
