Anthropic released Claude Opus 5, its most advanced Opus model, on Amazon Bedrock and Claude Platform on AWS with improvements in coding, agentic systems, and long-running tasks. The model matches Claude Fable 5's intelligence in many domains while maintaining Opus-tier pricing, and features zero data retention by default on Amazon Bedrock. Developers can now integrate Claude Opus 5 into production workloads across AWS infrastructure with enterprise security and data governance controls.
AWS, Google Cloud, Microsoft Azure, and Cloudflare have all launched isolated code execution sandboxes for AI agents within weeks of each other, but implemented them using different underlying technologies: AWS uses Firecracker VMs with up to eight hours of runtime, Google Cloud uses gVisor kernel interception or lightweight boundaries within Cloud Run, Azure uses Hyper-V with 400,000+ daily sessions for Copilot, and Cloudflare uses containerized VMs. Google charges no premium for Cloud Run sandboxes because they reuse allocated CPU and memory, demonstrated with 1,000 sandbox executions averaging 500 milliseconds each. The architectural differences mean vendor-specific limits persist—Lambda MicroVMs cap at eight hours and run only on Graviton in five regions, while Cloud Run sandboxes share the parent instance's resources—keeping governance and orchestration decisions separate from containment boundaries.
AWS published an architectural guide for building a deep learning-based product recommendation system for banks using SageMaker and PyTorch, with four specialized neural network towers processing different customer data types. The system uses a multi-tower architecture with GRU for sequence processing and attention mechanisms for learned fusion, requiring ml.g5.12xlarge GPU instances (192 GB RAM, 4× NVIDIA A10G GPUs) for training. Banks can now provide personalized product recommendations with built-in explainability that addresses regulatory requirements without needing post-hoc interpretation methods.
OpenAI's GPT-5.6 Sol, Terra, and Luna models are now available on Amazon Bedrock, offering developers access to frontier models through familiar APIs with AWS security and regional processing. The three models are priced at OpenAI's first-party rates and available in select US regions, with Sol optimized for reasoning, Terra for general production work, and Luna for fast, low-cost inference. Users can access these models through the bedrock-mantle endpoint using OpenAI SDKs, and benefit from prompt caching that reduces costs by 90% for repeated context processing.
