Amazon Titan Text Express and Amazon Titan Text Lite are large language models (LLMs) that help customers improve productivity and efficiency for an extensive range of text-related tasks, and offer price and performance options that are optimized for your needs. You can now access these Amazon Titan Text foundation models in Amazon Bedrock, which helps you easily build and scale generative AI applications with new text generation capabilities.
Amazon Titan Text Express has a context length of up to 8,000 tokens, making it well-suited for a wide range of advanced, general language tasks such as open-ended text generation and conversational chat, as well as support within Retrieval Augmented Generation (RAG). This model is optimized for English, with multilingual support for more than 100 additional languages available in preview. Alternatively, with a context length of up to 4,000 tokens, Amazon Titan Text Lite is the fastest model in the Titan Text family and is ideal for fine-tuning and English-language tasks, including summarization and copywriting, where you may want a smaller, more cost-effective text generation model that is also highly customizable.
Amazon Titan Text Express and Amazon Titan Text Lite foundation models in Amazon Bedrock are now generally available in the US East (N. Virginia), US West (Oregon), Asia Pacific (Singapore), Asia Pacific (Tokyo), and Europe (Frankfurt) AWS Regions.
