Community Voice & Feedback
Less than half the output tokens is the claim I would want to watch in a real agentic loop. On my own app the tokens that hurt were never the ones in the clean runs. They were the retries and the tool calls that went nowhere, and a benchmark never sees those.I keep my model id behind remote config so a swap does not need a new build to go out. Is 5.2 to 5.3 drop in at the API level, or does the prompting need reworking for the high effort mode?
Hi everyone!GLM-5.2 was already used on-prem by @Hugging Face last month to investigate the autonomous-agent intrusion into its infrastructure, after hosted frontier models ran into cyber-safety restrictions.GLM-5.3 keeps the exact same base model as 5.2. @Z.ai simply kept scaling the post-training stack, and the gains are pretty substantial. On their internal code benchmark, 5.3 at high effort beats Opus 4.8 while using less than half the output tokens.Cyber improved even faster. GLM-5.3 now scores 84.5 on CyberGym, and the model has started reasoning through complete exploitation chains. Their disclosure ledger currently tracks 1,097 critical and high-severity findings across 269 open-source projects.You can try GLM-5.3 now through GLM Coding Plan and ZCode. Open weights are planned in two weeks, after the remaining safety evaluation and hardening.
