Z.AI MaaS platform tops 7 million users as ARR soars 15x

Z.AI's Model-as-a-Service platform has drawn close to 7 million registered API users, up about 2 million since early July, as the Chinese AI developer's annualized revenue run rate climbs 15-fold this year. The figure, reported by LatePost citing people familiar with the matter, includes 23,000 corporate clients.

Some investors have said annualized recurring revenue could reach USD 2 billion by year-end, a projection Z.AI officially denied even as people close to the company indicated the actual figure could be higher. The developer product ZCode, benchmarked against OpenAI's Codex, surpassed 1 million users within a month of launch. Based on a USD 2 billion run-rate calculation, registered users spent an average of about RMB160 on the open platform during the month.

The user surge has not slowed even after rival model launches from Kimi and Alibaba's Qwen, according to the report. Morgan Stanley raised its price target on Z.AI to HKD 1,700 while cutting MINIMAX-W to HKD 900, a sign investors are consolidating around the platform's monetization. Z.AI shares rose 3 percent on the day, with short selling of $125.39 million representing a 2.017 percent ratio.

The platform's pull

The MaaS model — selling API access to AI models rather than one-off software licenses — is emerging as the clearest revenue path for Chinese AI developers, who have spent heavily on training compute. Z.AI's 7 million registered users and 23,000 corporate clients give it a distribution base that rivals like MINIMAX-W and Alibaba's Qwen are still building. The RMB160 average monthly spend per user, while modest, compounds across a seven-figure user base.

ZCode's 1 million users within a month of launch mirrors the early traction OpenAI's Codex saw among developers, giving Z.AI a foothold in the coding-assistant market that has become a key battleground for AI monetization. The product's benchmark against Codex shows Z.AI is targeting the same developer workflow that has made GitHub Copilot a commercial success.

What's at stake

The ARR trajectory matters because it determines how investors value Chinese AI names against US peers. A USD 2 billion run rate would put Z.AI's platform revenue on par with mid-tier US AI infrastructure companies, justifying the premium Morgan Stanley's HKD 1,700 target implies. The company's denial of the year-end projection, paired with sources indicating a higher figure, leaves the market to price in a wide range.

For investors, the key question is whether Z.AI can sustain the growth as Kimi and Alibaba push competing models. The report's finding that ARR growth was unaffected by those launches suggests the platform's developer lock-in is holding. Z.AI shares, up 3 percent on the day, trade with a short ratio of 2.017 percent, indicating limited bearish bets despite the valuation debate.
