> GLM Coding (China)
Zhipu AI's GLM platform (bigmodel.cn, also served at open.bigmodel.cn) sells model access per token in CNY and bundles agentic coding into a separate GLM Coding Plan. The official pricing page lists GLM-5.3 at 8 yuan per million input tokens, 2 yuan per million cached tokens and 28 yuan per million output tokens with a 1M-token context, and GLM-5.3-Flash at 0.8 / 0.23 / 2.8 yuan. New accounts receive 20 million free tokens on registration, and the text model GLM-4.7-Flash (200K context) and vision model GLM-4.6V-Flash are listed as free for input, output and cache. The GLM Coding Plan shows 118 yuan/month (Lite), 538 yuan/month (Pro) and 1078 yuan/month (Max), with discounted continuous-subscription prices of 94.4 / 430.4 / 862.4 yuan and quarterly billing at 8-fold and annual at 7-fold discounts.
// pros
- Two API models are priced at zero: GLM-4.7-Flash (200K context) and GLM-4.6V-Flash are stated as free for input, output and cache on the official pricing page.
- New-user grant of 20 million tokens: the pricing page states new registrations receive 20,000,000 tokens, with up to 200 million tokens reachable through the referral programme.
- GLM Coding Plan Lite is 118 yuan/month list (94.4 yuan on the discounted continuous options) and includes 10,000 credits per week plus support for 20+ coding tools including Claude Code, Codex, Cursor and OpenCode.
- Tier scaling is explicit: Pro is 6x the Lite usage allowance and Max 14x, with quarterly billing at an 8-fold discount and annual at 7-fold.
- Flagship GLM-5.3 offers a 1M-token context at 8 yuan per million input and 28 yuan per million output tokens, and the Batch API is billed at 50% of standard rates.
// cons
- The 20 million tokens are a one-time registration bonus, not a recurring free allowance; no perpetual free chat tier is documented.
- Coding-plan quota is expressed as 10,000 credits per week, so sustained agent use is capped and the allowance resets weekly.
- All prices are quoted in CNY on a Chinese-language console; no USD list price appears on the pages fetched.
- Cache storage is marked free for a limited time only, signalling that the zero-cost cache component is temporary.
Start with GLM-4.7-Flash and GLM-4.6V-Flash for zero-cost prototyping, then add GLM Coding Plan Lite (94.4 yuan/month on continuous billing) if you want Claude Code-style agent work, moving to Pro or Max only when the weekly credit allowance becomes the bottleneck.

Free tier present — value not quantified
This provider offers a free tier, but its terms don’t convert cleanly into a USD figure (e.g. request-count limits or capacity-dependent pools). We refuse to print a misleading zero here. See the note below and the official pricing page for the exact limits.
note: Free grant is 20,000,000 GLM tokens for new registrations (tokens, not currency), stated on bigmodel.cn/pricing and bigmodel.cn/claude-code; GLM-4.7-Flash and GLM-4.6V-Flash are additionally free per token.

$ Is GLM Coding (China) safe to use?
Uprouter rates GLM Coding (China) as low risk. Medium risk. The pricing pages carry an explicit plan-benefit change notice, several discounts are marked limited-time, and the platform operates in CNY with real-name registration required for the referral token bonus. On the positive side, the coding-plan documentation states that enterprise data is not used for model training by default and that IP whitelisting is supported, which lowers data-handling risk for team use. Risk ratings are editorial, evidence-based, and never influenced by affiliate relationships.
Raw community sentiment, shown unblended. Votes never feed into objective data fields like price, risk, or status — and never into sort order.
