GLM-5.3 (Terminal-Bench 3.0 #1 open-source) and the new GLM-5.3-Flash (native multimodal, live Aug 26, coding near Claude Opus 4.8) are available on all tiers. Credits refresh on a 5-hour + weekly dual window, with 50% off-peak deduction; quarterly 20% and yearly 30% discounts.
All plans support GLM-5.3 and GLM-5.3-Flash; calls to legacy models are auto-routed to the new versions.
Newest flagship, live for all users since Aug 14. Same base as 5.2 with post-training scaling: +50% coding on Z.ai Code Bench, #1 open-source on Terminal-Bench 3.0 (28.3), DeepSWE v1.1 at 66.9. Weights released on HuggingFace Aug 28.
Live Aug 26: the first natively multimodal model in the GLM-5 family (320B total / 18B active params, hybrid linear+sparse attention). DeepSWE v1.1 at 63.4 beats GLM-5.2; coding/agent near Claude Opus 4.8. Consumes 3x the usage of GLM-5.3 (lower Credits rate). Weights open-sourced under MIT.
Calls to GLM-5.2 / GLM-5.1 automatically switch to GLM-5.3; GLM-5-Turbo / GLM-4.7 switch to GLM-5.3-Flash — no config change needed.
Monthly prices with quarterly 20% / yearly 30% off. Credits refresh on a 5-hour + weekly dual window; off-peak usage (outside Mon-Fri 14:00-18:00 UTC+8) deducts 50%.

Peak hours are Mon-Fri 14:00-18:00 (UTC+8); everything else deducts 50% fewer Credits — Z.ai claims up to 92% savings vs pay-as-you-go GLM-5.3 API.
Visual understanding, web search, web reading and open-source repo access (1.2 Credits per call).
Weekends and weekday nights deduct half Credits — schedule heavy jobs accordingly.
ZCode 1.5x plan limits until Aug 31; invite program returns 10-20% Credits (overseas).
GLM-5.3-Flash weights are open under MIT; GLM-5.3 flagship weights landed on HuggingFace Aug 28.
Lite $18/mo (yearly $12.6/mo), Pro $80/mo (yearly $56/mo), Max $168/mo (yearly $117.6/mo). Quarterly billing gives 20% off, yearly 30% off.
Credits refresh on a dual window: 5-hour (Lite 2,000 / Pro 12,000 / Max 28,000) plus weekly (10,000 / 60,000 / 140,000). Off-peak usage (outside Mon-Fri 14:00-18:00 UTC+8) deducts 50% fewer Credits; flagship models consume Credits faster.
A new model live Aug 26: the first natively multimodal model in the GLM-5 family (320B total / 18B active parameters). DeepSWE v1.1 at 63.4 beats GLM-5.2 and coding/agent capability approaches Claude Opus 4.8. It uses 3x the usage of GLM-5.3 (a lower Credits rate) and its weights are open-sourced under MIT.
All tiers support GLM-5.3 (Terminal-Bench 3.0 #1 open-source) and GLM-5.3-Flash (native multimodal). Calls to legacy GLM-5.2/5.1 auto-route to GLM-5.3, and GLM-5-Turbo/4.7 auto-route to GLM-5.3-Flash.
Yes. GLM-5.3-Flash weights are open under MIT, and the GLM-5.3 flagship weights were released on HuggingFace on Aug 28 as promised (two weeks after launch).
No. Visual understanding, web search, web reading and open-source repo MCP tools are included in every tier.
