Meta on Wednesday announced Spark, the first AI model in the Muse family that it says represents “a ground-up overhaul of our AI efforts.” Muse Spark is the first release of Meta’s Superintelligence Labs, formed a little less than a year ago with the grandiose goal of “deliver[ing] on the promise of personal superintelligence for everyone.” The release represents a clean break from Meta’s previous work on the open source Llama model family, which has received a middling […]

Today, we’re sharing how Amazon Bedrock makes it straightforward to customize Amazon Nova models for your specific business needs. As customers scale their AI deployments, they need models that reflect proprietary knowledge and workflows — whether that means maintaining a consistent brand voice in customer communications, handling complex industry-specific workflows or accurately classifying intents in a high-volume airline reservation system. Techniques like prompt engineering and Retrieval-Augmented Generation (RAG) provide the model with additional context to improve task performance, […]

In healthcare and life sciences, AI agents help organizations process clinical data, submit regulatory filings, automate medical coding, and accelerate drug development and commercialization. However, the sensitive nature of healthcare data and regulatory requirements like Good Practice (GxP) compliance require human oversight at key decision points. This is where human-in-the-loop (HITL) constructs become essential. In this post, you will learn four practical approaches to implementing human-in-the-loop constructs using AWS services. Why human-in-the-loop matters in healthcare Healthcare and life […]

If you’re looking to enhance your content understanding and search capabilities, audio embeddings offer a powerful solution. In this post, you’ll learn how to use Amazon Nova Multimodal Embeddings to transform your audio content to searchable, intelligent data that captures acoustic features like tone, emotion, musical characteristics, and environmental sounds. Finding specific content in these libraries presents real technical challenges. Traditional search methods like manual transcription, metadata tagging, and speech-to-text conversion work well for capturing and searching spoken […]

You can use reinforcement Fine-Tuning (RFT) in Amazon Bedrock to customize Amazon Nova and supported open source models by defining what “good” looks like—no large labeled datasets required. By learning from reward signals rather than static examples, RFT delivers up to 66% accuracy gains over base models at reduced customization cost and complexity. This post covers best practices for RFT on Amazon Bedrock, from dataset design, reward function strategy, and hyperparameter tuning for use cases like code generation, […]

We live in a digitally connected world that has brought undeniable personal benefits. I can barely recall the pre-Google Maps era, but it was far less convenient to navigate unfamiliar places without a Siri-enabled smart phone (and/or Apple Car Play). We use fitness tracking apps, our home appliances are increasingly digitally connected, and many homes have security systems like Nest cameras or home assistants like Alexa or Amazon Echo. But what are we giving up for all this […]
