⚡ Assistant 💵 Freemium: consumer chat is free; developer subscriptions and API usage are paid separately 📅 Listed Sep 16, 2026

Our take

Z.ai provides GLM-powered chat, research, coding and agent assistance, free for consumer chat with paid developer access. Free consumer tiers backed by capable models are genuinely useful, and the consideration worth raising is jurisdictional: where a model is operated affects what data protection and disclosure obligations apply to what you send it.

Worth it if

Users wanting free access to a capable assistant, and developers evaluating GLM models.

Look elsewhere if

Regulated or confidential material without first checking data handling and jurisdiction.

❓ Frequently Asked Questions

Does it matter where a model is operated?

For confidential or regulated data, yes. Data protection obligations, retention practices and government access regimes differ by jurisdiction, and transferring personal data across borders carries its own requirements under several privacy regimes. For general use it rarely matters; for client or employee data it is the first question.

What is the catch with free consumer access?

Usually that conversations may be used for training and that limits apply above light use — which is the same trade every free assistant tier makes. Read the data terms specifically rather than assuming they match a provider you already use, since defaults vary considerably.
