Writer Unveils Cost-Cutting Palmyra X6 AI Model and Upgraded Harness

Writer has launched its new flagship AI model, Palmyra X6, alongside significant upgrades to its agentic harness. The company aims to cut token costs for enterprise customers by up to 50% on basic tasks.

The Palmyra X6 model is built as a post-training variation of Z.ai's open-source model GLM-5.2 and offers deployment-ready capabilities at a lower price point.

Writer's CEO, May Habib, emphasized that enterprises are 'absolutely sick of chasing the next benchmark' and are demanding flattening costs.

The company's focus on harness optimization is designed to deliver cost efficiency, with research showing that small changes in harness efficiency can reduce costs by an average of 40% across multiple models.
