About

Palmyra X 003, developed by Writer AI, is a state-of-the-art large language model tailored for structured text completion rather than conversational tasks. Building on its predecessor, Palmyra X 002, this model enhances performance by generating precise and detailed responses, making it ideal for creating structured documents like reports and proposals. Its capabilities extend to data-driven analysis, allowing it to summarize complex datasets into actionable insights while supporting multiple languages for global reach. Initially ranked #3 on Stanford's HELM benchmark, it later achieved the top spot in translation accuracy. With a context length of 32k tokens, it is accessible through Writer's AI Studio and API, with a pricing model based on tokens used.

Palmyra X 003 input tokens at $7.5/1M, output at $1/1M.
