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.

Description

Prime Intellect serves as a comprehensive superintelligence framework, offering a cohesive platform for computation, training, inference, and experimentation for groups aiming to develop, implement, and enhance their models over time. Instead of relying on advancements from frontier models, the stack emphasizes ownership of intelligence, providing users with a singular loop for reinforcement learning environments, extensive training, evaluations, inference, and computing needs. Within the Lab, teams can enable self-improving agents by transforming tasks into reinforcement learning settings and utilizing the Prime CLI for creation, development, evaluation, and deployment. The Environment Hub presents access to an extensive collection of over 2,500 open-source RL environments, while hosted evaluations allow teams to assess model performance across various open-source frameworks without the burden of managing infrastructure. Additionally, Hosted Training facilitates large-scale models tailored for agentic workflows, ensuring managed training processes with complete visibility and control, along with direct assistance from the dedicated applied research team, allowing for a more robust and user-friendly experience in model development. This integrated approach not only streamlines the development process but also fosters innovation and collaboration among teams.
