AWS – Writer’s Palmyra X5 and X4 models are now available in Amazon Bedrock

Writer’s enterprise-grade foundation models, Palmyra X5 and X4, are now available as fully managed, serverless models in Amazon Bedrock. AWS is the first cloud provider to offer fully managed models from Writer, allowing organizations to leverage enterprise AI capabilities with serverless scalability and cost optimization.

Palmyra X5 has a one million token context window, while Palmyra X4 features a 128,000 token context window, both designed for sophisticated business applications. These models, top-ranked on Stanford’s HELM benchmark, excel at complex tasks including advanced reasoning, multi-step tool-calling, and built-in RAG (Retrieval-Augmented Generation). Both models support multiple languages including English, Spanish, French, German, and Chinese, making them ideal for global enterprise deployments. Organizations can use Palmyra models to automate sophisticated workflows across various industries—financial services teams can analyze extensive market research and regulatory documents, healthcare providers can process medical documentation and analyze research papers, and technology companies can generate and validate code at scale. With Amazon Bedrock, these capabilities are available with automatic resource scaling and on-demand pricing.

Writer’s Palmyra X5 and X4 models are now available in the US West (Oregon) AWS Region. For more information on supported Regions, visit the Amazon Bedrock Model Support by Regions guide.
