Anatomy of Zhipu's Open-Source Gamble: $110M Revenue, Volatile Valuation
On November 9, blogger ccerrato147 published a long thread systematically breaking down Zhipu's (Z.ai internationally) history and its "build the product, then give it away free" business model: the company booked $110M revenue last year with R&D spending over twice that, and in 2025 reported $110M revenue against $700M in losses, after being added to the US Entity List in January. Whether open-source prestige can convert into contracts others can't win is the thread's central open question.
Confirmed
- Tsinghua origins: Zhang Peng joined Tsinghua University's Knowledge Engineering Group (KEG) in 2002, with the creed "Paper to Product"; the first product was academic search engine AMiner, which became Zhipu in 2019. When GPT-3 launched in 2020, Zhang's advisor Zhang Bo judged it "spouts nonsense and doesn't know what it knows," yet Zhang Peng insisted on rebuilding methods from the papers in-house.
- Early open-source reputation: Starting January 2022, the team trained the 130-billion-parameter GLM-130B on 96 A100s, fitting on a single A100 server, repeatedly hitting OOM, gradient, and hardware failures along the way; the final successful training took about two months and roughly $600K. In November 2022, GLM-130B became the only Chinese model among Stanford's 30-model benchmark—scores below closed-source models, but it put them on the world's radar.
- Closed-source monetization failed: GLM-4 launched January 2024 with 200 billion parameters, benchmarking at roughly 90% of GPT-4, sold closed-source via API only; but just four months later DeepSeek V2 slashed prices and the whole industry followed, killing that revenue route.
- To-C flop: Zhipu's consumer app never broke 11M MAU, versus ByteDance's Doubao at roughly 324M; Zhipu then pivoted to B2B enterprise business.
- Open-source peak: In July 2025, Zhipu open-sourced GLM-4.5 weights under MIT license, topping Hugging Face within 48 hours; afterward, companies outside China began integrating it into their own products.
- IPO and valuation swings: Zhipu listed on the Hong Kong exchange in January at roughly a $7B valuation; within five months its market cap briefly hit $170B (nearly half of Alibaba's), but by end of September about $130B had evaporated.
- Competitive landscape: Three weeks after ChatGPT's launch in late 2022, Zhipu already had a comparable model in training and rushed out a chatbot over Chinese New Year; investors had once demanded Zhipu halve its valuation, then capital flooded in and the same race saw over 130 competitors.
Why it matters
- Zhipu represents an extreme business path: build the model on paid R&D, then give the weights away free, betting open-source prestige converts into enterprise contracts. There are two monetization routes—cloud API access and private deployment—the logic being that even with a freely downloadable model, customers still need GPUs, operational assurance, security review, and responsive support; as ccerrato147 puts it, "that gap is the business, but it hasn't been filled yet."
- The author also flags the model's inherent contradiction: every downloader could become a competitor rather than a customer. With R&D spending double revenue and wild market-cap swings, whether this model can work remains the case study the whole industry is watching.
