Zhipu AI announced that GLM-5.2 will fully launch its "Coding Plan" — a subscription service for AI coding assistance, similar to GitHub Copilot but powered by the open-source GLM-5.2. The standout: Zhipu is offering the Coding Plan at a significantly lower price than Copilot, betting that "open-source + low price" is a winning combination.
The "Coding Plan" details: the subscription costs ¥39/month (~$5.50), compared to GitHub Copilot's $10/month and Cursor's $20/month. The plan includes unlimited usage of GLM-5.2 for coding tasks (code completion, code generation, code review, debugging). The service is available via VSCode, JetBrains IDEs, and a web playground.
The "open-source + low price" bet: Zhipu's strategy is to use the low marginal cost of open-source models to offer a much lower price than closed-source competitors. The bet is that "low price + good enough quality" will attract a large user base, and the "user base" is the moat — not the model quality.
The benchmark: GLM-5.2 scores within 2-3 points of GPT-5.6-Code and Claude Sonnet 4.6 on HumanEval and SWE-Bench. The "good enough" quality, combined with the much lower price, is a compelling value proposition for price-sensitive developers.
The bigger takeaway: "open-source + subscription" is a viable business model. The "open-source doesn't make money" narrative is breaking, and the "low price + open-source" approach is the right strategy for the Chinese market. For the industry, this signals that the "AI coding" market is commoditizing, and the winners will be the vendors with the best price-quality ratio.
