How Koa Actually Works: Post-Training, Not a New Model From Scratch
Koa is not a model Salesforce trained from a blank slate. It is the open-weight NVIDIA Nemotron-3-Super-120B foundation model, post-trained with supervised fine-tuning and reinforcement learning using Group Relative Policy Optimization (GRPO), built with NVIDIA's NeMo RL, NeMo Gym, and NeMo AutoModel tooling[4]. The training corpus is entirely synthetic - generated from patterns drawn out of nearly 27 years of Salesforce's own CRM deployment history spanning 14 or more industries, from manufacturing to healthcare to travel - and Salesforce says no customer data was used[2][3]. On Salesforce's internal CRM action benchmark, that combination reportedly matches or beats leading general-purpose models while cutting errors by roughly two-thirds[3]. The pitch is narrow by design: rather than compete with Claude or GPT-5 on general reasoning, Koa is built to be good at one thing - the everyday, repetitive actions that make up most CRM work.
