Writer
Overview
Writer is a generative AI platform purpose-built for the enterprise. It is powered by Palmyra, Writer's in-house family of large language models, and is targeted at large organizations where security, governance, and brand consistency are non-negotiable. In 2026 the flagship is Palmyra X5—an adaptive reasoning LLM with a 1M-token context window—paired with domain-specific models for finance, medicine, and legal. Writer occupies a unique niche: building AI agents for regulated industries that generic chat AIs cannot serve. Primary audience: Fortune 500 companies, banks, insurers, healthcare, and law firms.
Key Features
1. Palmyra X5 (In-House LLM)
A 1M-token adaptive reasoning LLM built on a novel transformer architecture with hybrid attention. Delivers near GPT-4.1 performance at 75% lower cost. Priced at $0.60 per 1M input tokens and $6 per 1M output tokens.
2. Domain-Specific Models
Fine-tuned variants—Palmyra Fin, Palmyra Med, Palmyra Creative—cover finance, medicine, and creative work. X5 can dynamically delegate to the right domain model at runtime.
3. Enterprise Agent Building
Build autonomous agents that call external tools, delegate to other Writer agents, and dispatch to domain models. Deployed in financial reporting, legal document analysis, medical record synthesis, and customer feedback analysis.
4. Full Governance
Customers own their data and nothing is used for training. SOC 2 Type II, HIPAA, and GDPR compliant. Audit logs, access controls, and automatic brand-guideline enforcement are standard.
5. Amazon Bedrock Integration
Palmyra X5 is also available via Amazon Bedrock, making it easy to drop into existing AWS estates while preserving data sovereignty and regional controls.
