Koa vs. GLM-5

Salesforce Koa marks the company's first CRM reasoning model specifically designed for Agentforce, leveraging the power of NVIDIA Nemotron and drawing from an extensive 27 years of Salesforce CRM knowledge to adeptly handle complex, multi-step tasks in enterprise settings. This model is built upon nearly three decades of CRM application expertise and has been further refined through training on a specialized synthetic dataset that mirrors genuine business workflows, processes, and compliance requirements. The training scenarios are meticulously designed to emulate the reasoning, tool usage, and decision-making strategies that Agentforce agents utilize throughout the customer journey, including critical activities such as lead generation, opportunity qualification, and service case resolution across more than 14 distinct industries. Koa is purpose-built for precise CRM functionalities and is evaluated using the Salesforce CRM Bench, which includes authentic workflows like opportunity updates, case routing, and follow-up scheduling. Salesforce reports that Koa delivers an 11% improvement in accuracy for choosing the right actions and recalls customer context with a reliability that is 2.1 times superior to earlier models. This groundbreaking methodology not only boosts operational efficiency but also greatly enhances the overall customer experience, making it a vital tool for businesses aiming to optimize their customer interactions. By integrating advanced reasoning capabilities, Koa positions itself as a transformative solution in the realm of customer relationship management.

GLM-5 is Z.ai’s most advanced open-source model to date, purpose-built for complex systems engineering, long-horizon planning, and autonomous agent workflows. Building on the foundation of GLM-4.5, it dramatically scales both total parameters and pre-training data while increasing active parameter efficiency. The integration of DeepSeek Sparse Attention allows GLM-5 to maintain strong long-context reasoning capabilities while reducing deployment costs. To improve post-training performance, Z.ai developed slime, an asynchronous reinforcement learning infrastructure that significantly boosts training throughput and iteration speed. As a result, GLM-5 achieves top-tier performance among open-source models across reasoning, coding, and general agent benchmarks. It demonstrates exceptional strength in long-term operational simulations, including leading results on Vending Bench 2, where it manages a year-long simulated business with strong financial outcomes. In coding evaluations such as SWE-bench and Terminal-Bench 2.0, GLM-5 delivers competitive results that narrow the gap with proprietary frontier systems. The model is fully open-sourced under the MIT License and available through Hugging Face, ModelScope, and Z.ai’s developer platforms. Developers can deploy GLM-5 locally using inference frameworks like vLLM and SGLang, including support for non-NVIDIA hardware through optimization and quantization techniques. Through Z.ai, users can access both Chat Mode for fast interactions and Agent Mode for tool-augmented, multi-step task execution. GLM-5 also enables structured document generation, producing ready-to-use .docx, .pdf, and .xlsx files for business and academic workflows. With compatibility across coding agents and cross-application automation frameworks, GLM-5 moves foundation models from conversational assistants toward full-scale work engines.
