Z.ai (ChatGLM)

FreemiumAI chatfreemium

Z.ai is Zhipu AI's chat and developer platform built on the GLM model family (formerly ChatGLM), and one of the fastest-moving labs of 2026. Basic chat on GLM Flash models is free and unlimited, while the flagship GLM-5.x reasoning models -- which rival Opus-class systems on agentic and coding tasks -- come via cheap coding-plan subscriptions (from ~$10/mo) or a very low-cost API. Developers get a strong, English, OpenAI-compatible platform with genuinely free Flash models, not just trial credits. The catch is China jurisdiction and PRC-aligned content rules, plus fast-shifting pricing.

EDITORIAL VERDICT · BIGBANGINDEX

Z.ai (ChatGLM) edges Typebot on aggregate — 88 vs 83.

The best price-to-performance AI chat and API of 2026 -- free unlimited Flash chat and near-frontier paid models for cents, if your org is comfortable with a China-based provider.
