AWS Bedrock is a fully managed service that provides access to leading foundation models (FMs) from prominent AI companies like AI21 Labs, Anthropic, Cohere, Meta, Mistral AI, Stability AI, and Amazon’s own high-performing models. It allows you to access these models through a single API and leverage a wide range of tools to build generative AI applications.
Here are the primary AI models available on AWS Bedrock:
1. Amazon Titan Family
These are Amazon’s own foundational models, designed for various tasks:
- Amazon Titan Text Models (e.g., Express, Lite, Premier): Used for text generation and embedding. They can handle a wide array of text-based tasks, from content creation to summarization.
- Amazon Titan Image Generator: For creating images from text descriptions.
- Amazon Titan Multimodal Embeddings: Used for understanding and embedding various content types, including text, images, and potentially video, to enable multimodal search and recommendations.
2. Anthropic Claude Series
Known for their conversational abilities, long-context understanding, and advanced reasoning:
- Claude, Claude Instant, Claude 2.x, and the Claude 3 series (Haiku, Sonnet, Opus): These models excel at complex dialogue, long-form content generation, logical reasoning, and maintaining safety and reducing bias. Haiku is fast and cost-effective; Sonnet balances intelligence and speed; Opus offers the highest level of intelligence.
3. AI21 Labs Jurassic Series
Powerful models for text generation and comprehension:
- Jurassic-2 Ultra and Jurassic-2 Mid: These are well-suited for multilingual text generation, question answering, and summarization, especially in scenarios requiring long context and complex reasoning.
4. Cohere Command & Embed Series
Designed for advanced language understanding and generation:
- Command: Excellent for sophisticated chat applications and text generation.
- Embed: Used for creating text embeddings, enabling capabilities like semantic search and information retrieval.
5. Meta Llama Series
Open-source large language models with strong general-purpose capabilities:
- Llama 2 and Llama 3: These models are versatile and can be applied to a wide range of natural language processing tasks, including dialogue, text classification, and generation.
6. Mistral AI Models
Known for their efficiency, high performance, and advanced reasoning:
- Mistral Small, Mistral Large: These models offer strong capabilities for various language tasks, balancing performance with computational efficiency.
7. Stability AI Stable Diffusion Series
Primarily focused on image generation:
- Stable Diffusion XL (SDXL): A prominent text-to-image model that generates high-quality images from textual descriptions, making it ideal for creative content development, advertising, and media industries.
8. Other Models
Bedrock continues to expand its offerings, which may include models from:
- DeepSeek: Providing high-performance language models.
- Luma AI: Focusing on multimodal content generation.
- Writer AI Palmyra: Specialized in text generation and content creation.
Key Benefits of AWS Bedrock:
