Writer has launched a new flagship model called Palmyra X6 along with upgrades to its agentic harness. The company, which builds AI tools and agents for marketers, says the combination can cut costs for customers by as much as 50% on basic tasks. Palmyra X6 is a post-training variation of Z.ai’s open-source GLM-5.2 model and is designed to deliver deployment-ready capabilities at a lower price. The upgraded harness focuses on complex multi-step tasks that run faster and use fewer tokens. Writer research found that harness changes alone reduced costs by an average of 40% across tested models, often proving a more reliable lever than model choice. The experience remains model-agnostic: users can run Palmyra X6 alongside other Writer models or external models via Azure or Amazon Bedrock. CEO May Habib said enterprises are tired of chasing benchmarks and want flatter costs. Both the model and harness upgrades became available to Writer clients on Thursday.
