About
Amazon Titan Text is Amazon’s text-generation LLM family on Amazon Bedrock, with Titan Text Lite, Express, and Premier. The models support summarization, text generation, classification, question-answering, and information extraction. Premier is positioned as an advanced enterprise text model optimized for Retrieval Augmented Generation and Bedrock agents; Bedrock docs document the family’s inference API and per-model max token counts (Lite, Express, and Premier).
