Palmyra X4 is an enterprise-grade large language model developed by Writer, designed to power advanced AI applications and agentic workflows. It features a 128,000-token context window, enabling the model to process and reason over large volumes of data in a single prompt. Palmyra X4 introduces intelligent action capabilities, allowing the model to take actions in external systems via tool-calling, automate data integration with built-in retrieval-augmented generation (RAG), and generate and deploy code. The model supports structured output for easier system integration, multi-modal inputs (including images, audio, and video), and multi-lingual capabilities in over 30 languages. Palmyra X4 is benchmarked as a top performer on industry leaderboards, including Stanford HELM and Berkeley’s Tool Calling Leaderboard, and is available through platforms like Amazon Bedrock, Ask Writer, and AI Studio. It is also notable for being trained on synthetic data, offering cost-effective and scalable enterprise AI.
