Description
Fugu Cyber is an advanced orchestration model designed specifically for contemporary cyber defense, operating as a unified entity through a single API endpoint while adeptly managing multiple specialized agents to tackle intricate security challenges. This innovative model does not rely on a single provider and is tailored for two main defense operations: assessing complex codebases to identify genuine vulnerabilities and converting raw cyber threat intelligence into actionable detection rules. Its performance on CyberGym, which tests vulnerability analysis and validation, resulted in an impressive success rate of 86.9%, whereas on CTI-REALM, which evaluates the generation of detection rules from threat intelligence reports, it achieved a score of 72.1%. These results position Fugu Cyber among the top-tier models focused on cybersecurity innovations. Rather than functioning as an isolated tool, Fugu Cyber is designed to serve as the cognitive engine within larger security infrastructures, enhancing overall defense capabilities against evolving cyber threats. This integration allows for a more holistic approach to cyber defense, enabling organizations to respond more effectively to potential attacks.
Description
GLM-5.3 is Z.ai’s advanced coding and agentic reasoning model built through scaled post-training on top of the GLM-5.2 base model. The release focuses on frontier coding, long-horizon software engineering, agent tasks, cyber evaluation, and reinforcement learning at scale. GLM-5.3 improves significantly over GLM-5.2 on complex coding benchmarks, real-world engineering environments, Terminal Bench 3.0, DeepSWE, Agents’ Last Exam, and Z.ai’s internal Code Bench. The model is trained on environments that resemble real professional work, including tasks involving codebases, infrastructure, documentation, compute clusters, experiments, bottleneck diagnosis, implementation, testing, and measurable optimization. Z.ai’s post-training stack includes IndexShare for efficient long-context processing, SAO for reinforcement learning on long-horizon tasks, and slime for large-scale asynchronous training. GLM-5.3 supports three thinking effort levels, including low, high, and max, with max recommended for coding tasks. The model also demonstrates emergent cyber capabilities across vulnerability discovery and exploitation benchmarks, prompting continued safety evaluation and hardening before weights are released. GLM-5.3 can be used through the GLM Coding Plan, ZCode, Claude Code, OpenCode, and other coding agent workflows. By combining stronger coding performance, long-horizon task execution, post-training scale, cyber evaluation, reasoning effort controls, and coding-agent integrations, GLM-5.3 supports advanced developer and research workflows.
