baseten · x · 2026-08-29
Z.AI released GLM-5.3, a 743B MoE model under the MIT license. The model achieves significant improvements in long-horizon agentic capabilities and cybersecurity analysis through scaled post-training, with Terminal-Bench 3.0 scores jumping from 4.6% to 28.3%. It supports three thinking effort levels (low, high, max), designed for production-scale coding workflows requiring sustained planning and verification.
