Z.ai Review, Pricing and Alternatives

Our verdict

Z.ai positions itself as meet Z.ai, the AI assistant powered by GLM-5.2. Build websites, write code, handle long-horizon tasks, and get instant answers. Fast, smart, and reliable. No free tier is advertised, though pricing is at least public. Developer documentation and a public changelog are both maintained, which is a good sign for anything you intend to build on. We have not verified the prices by hand, so we do not quote them here. Everything above was checked on 2026-08-26.
