Building specialized AI without sacrificing intelligence: Nova Forge data mixing in action

by

Large language models (LLMs) perform well on general tasks but struggle with specialized work that requires understanding proprietary data, internal processes, and industry-specific terminology. Supervised fine-tuning (SFT) adapts LLMs to these organizational contexts. SFT can be implemented through two distinct methodologies: Parameter-Efficient Fine-Tuning (PEFT), which updates only a subset of model parameters, offering faster training … Read more

Build a serverless conversational AI agent using Claude with LangGraph and managed MLflow on Amazon SageMaker AI

by

Customer service teams face a persistent challenge. Existing chat-based assistants frustrate users with rigid responses, while direct large language model (LLM) implementations lack the structure needed for reliable business operations. When customers need help with order inquiries, cancellations, or status updates, traditional approaches either fail to understand natural language or can’t maintain context across multistep … Read more

Build safe generative AI applications like a Pro: Best Practices with Amazon Bedrock Guardrails

by

Are you struggling to balance generative AI safety with accuracy, performance, and costs? Many organizations face this challenge when deploying generative AI applications to production. A guardrail that’s too strict blocks legitimate user requests, which frustrates customers. One that’s too lenient exposes your application to harmful content, prompt attacks, or unintended data exposure. Finding the … Read more

Merkle Trees 101 (Part 1): Structure, Proofs, and Real-World Uses

by

Part one of this series breaks down Merkle trees from first principles, starting with basic tree data structures and traversal methods before introducing hierarchical cryptographic hashing. It explains how inclusion proofs work and why Merkle trees scale logarithmically, making them essential for blockchain networks, distributed filesystems, version control systems, and peer-to-peer infrastructure.

Nvidia’s spending $4 billion on photonics to stay ahead of the curve in AI

by

Nvidia announced on Monday that it’s investing $2 billion each into Lumentum and Coherent, which are both developing photonics technology for data centers, like optical transceivers, circuit switches, and lasers, which are used to move data at high speeds over long distances. Their tech could improve energy efficiency, data transfer speeds, and bandwidth in future … Read more
