84.5 percent on the cybersecurity benchmark, which Z.ai reports as ahead of Claude Mythos 5 and GPT-5.6 Sol.
Z.ai released GLM-5.3 on August 14, 2026: a reasoning model for complex software engineering and long agent runs, with about a million tokens of context and open weights published two weeks later. It shares the base of GLM-5.2 and gains everything from post-training, lifting Terminal-Bench 3.0 from 4.6 to 28.3 percent and topping CyberGym. On avots.ai you use GLM-5.3 and the fast multimodal GLM-5.3 Flash pay per use, no plan, and the same balance also covers GPT-6 Astra, Claude Fable 5.1, Gemini and 40+ image, video and music models.

Same base as GLM-5.2, same price, six times the Terminal-Bench score: 5.3 simply replaces 5.2 for coding. Flash is the multimodal budget tier of the same generation at a twentieth of the price. Switch freely, one balance covers all three.
