Brief by The AI News AI newsroom · Sep 8, 2026, 11:14 AM EDT edition
Original reporting by Interconnects (Nathan Lambert) — Florian Brand · published Sep 8, 2026, 10:15 AM EDT
Anyone hosting GLM-5.3 as a commercial service now faces licensing conditions — and an undefined 'affiliates' clause — that GLM-5.2's MIT license never imposed.
Key points
- GLM-5.3 dropped MIT for a custom license requiring providers above $10 billion revenue to pass a Z.AI security review. source ↗
- The license leaves 'affiliates' undefined in English, though the Chinese text uses a term defined in Chinese law. source ↗
- Kimi K3 requires commercial agreements for inference or fine-tuning services; MiniMax M3 adds a revenue threshold and prohibited uses. source ↗
- Google and Meta switched to Apache 2.0 in 2026 as Chinese frontier labs moved toward more restrictive licenses. source ↗
- DeepSeek's move to MIT with R1 pushed many Chinese model makers toward MIT or Apache 2.0 in 2025. source ↗
The data
$10 billion
12-month revenue above which model-as-a-service providers must pass Z.AI's security review
The threshold applies to the combined revenue of the licensee and its affiliates, and 'affiliates' is undefined in the English text.

Practical applications
- Have counsel review GLM-5.3's custom license, especially the undefined 'affiliates' clause, before offering it as a hosted inference or fine-tuning service.
- Do not assume upgrading from GLM-5.2 to GLM-5.3 keeps MIT terms; re-run license review before deploying the new weights.
- Factor Kimi K3's and MiniMax M3's commercial-agreement requirements into model selection for any paid serving offering.
Context
Open-weight models have oscillated between permissive licenses like MIT and Apache 2.0 and custom ones like Llama's or the Qwen2.5 72B license. This piece describes a 2026 split: Western labs loosening to Apache 2.0 while Chinese frontier labs attach commercial conditions such as revenue thresholds and security reviews.
What to watch
- Whether Z.AI clarifies or defines 'affiliates' in the English license text.
- Whether other Chinese frontier labs adopt similar revenue-threshold or security-review clauses in upcoming releases.
