Writer

1 model built

Writer, Inc. is a US enterprise generative-AI company, founded in 2020, known for the Palmyra family of LLMs built for regulated industries. On OpenKey, Writer has a single model available: Palmyra X5, released January 2026. That's a narrow lineup compared to labs with dozens of variants, but it reflects Writer's approach — one flagship model tuned for enterprise use rather than a spread of sizes and price points. Palmyra X5 stands out for its 1,040,000-token context window, which lets you feed in long documents, contracts, or multi-file codebases in a single call without chunking.

Lineup

There's no lineup to navigate here — Writer offers one model on OpenKey, Palmyra X5. Input runs $0.60 per 1M tokens, output $6.00 per 1M tokens (OpenKey price: $0.618 and $6.18 after the flat 3% fee: $0.60 × 1.03 and $6.00 × 1.03). If you need Writer's models at all, this is the one to use. Its selling point is the 1,040,000-token context window — worth reaching for on long-document or long-context tasks. For anything cheaper or free, you'll need a different lab; Writer has zero free models on OpenKey.
