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

Salesforce Koa represents the company's inaugural CRM reasoning model tailored for Agentforce, developed using NVIDIA Nemotron and enhanced by 27 years of accumulated Salesforce CRM expertise to navigate intricate, multi-step tasks in enterprise environments. Rooted in nearly three decades of CRM application experience, it has undergone additional training on a unique synthetic dataset that reflects authentic business processes, workflows, and operational regulations. The scenarios employed during training are designed to replicate the reasoning, tool utilization, and decision-making processes that Agentforce agents engage in throughout the customer journey, which includes activities like lead generation, opportunity qualification, and service case resolution, applicable across over 14 different sectors. Koa is specifically crafted for precise CRM functions and is assessed using Salesforce CRM Bench, incorporating genuine workflows such as opportunity updates, case routing, and follow-up scheduling. According to Salesforce, Koa achieves an 11% increase in accuracy for selecting appropriate actions and recalls customer context with a reliability that is 2.1 times greater than previous models. This innovative approach not only enhances efficiency but also significantly improves the overall customer experience across the board.
