Production MLOps at GS Caltex with Amazon SageMaker Canvas, part 1

GS Caltex uses Amazon SageMaker Canvas and Amazon SageMaker Pipelines to connect process engineers’ models to production workflows. The South Korean energy and chemical company divides model development and operations between engineers with complementary skills. Process engineers build and validate models in SageMaker Canvas without writing code, drawing on their process knowledge. Machine learning (ML) …

New AI agent observability and governance across BigQuery and Looker

As enterprises move AI agents from experimental prototypes into production, data and platform teams are discovering that deploying an agent is only half the battle — you also need to see how it reasons, which data it touches, and what it costs to run. Today, we are announcing expanded AI agent observability and evaluation capabilities …

Theoretical Limits of Language Model Alignment

Language model (LM) alignment improves model outputs to reflect human preferences while preserving the capabilities of the base model. The most common alignment approaches are (i) reinforcement learning, which maximizes the expected reward under a KL-divergence constraint, and (ii) best-of-NNN alignment, which selects the highest-reward output among NNN independent samples. Despite their widespread use, the …

Deploy frontier AI models on AWS Trainium with SGLang-Neuron

Today, Amazon announced that SGLang-Neuron is publicly available and can be accessed through an AWS Deep Learning Container, released by RadixArk in collaboration with Annapurna Labs. With SGLang-Neuron, you can serve models and generate reinforcement learning (RL) rollouts with SGLang on AWS Trainium using the same SGLang interface you use today. Trainium is a portfolio …

Evaluating the Evaluators: Investigating LLM Judges for Personalized Writing Style Assessment

This paper was accepted at the Can We Trust AI Evaluation? Workshop at NeurIPS 2026. We evaluate how good large language model (LLM) judges are for personalized writing tasks. This is important when a user’s preferred writing style is known (e.g., “upbeat”) and an LLM judge is used to evaluate whether generated text adheres to …

Build autonomous AI agents with Amazon Bedrock and Spring AI

Java teams have established JVM tooling, continuous integration and continuous delivery (CI/CD) pipelines, and operational patterns, yet taking AI agents from prototype to production is hard: agent frameworks do not solve scalability, governance, security, and operational concerns by default. Amazon Bedrock and Spring AI close those gaps, so Java teams can build autonomous AI agents …

Introducing new AI functions for AlloyDB: ai.classify and ai.extract

Transactional databases store vast amounts of unstructured text — clinical notes, customer reviews, support tickets, invoices, and property descriptions. Historically, working with this text meant building complex application code: You had to export data from the database, call external model endpoints, write custom prompt wrappers, parse unpredictable responses, manage retry logic, and update database records. …

Introducing Kimi K3.1 Pro on Amazon Bedrock

Kimi K3.1 Pro Highspeed from Moonshot AI is now available on Amazon Bedrock. Part of Moonshot AI’s new K3.1 series, it’s a post-trained version of Kimi K3 with the same 3T-class open-weight architecture and 1-million-token context window, trained with substantially more post-training compute. According to Moonshot AI, that extra training targets long-horizon agentic work and …

Introducing Gemini for healthcare

Every healthcare organization is working to deliver great care to more people at a lower cost. However, a general AI model is not enough to solve this challenge. Today, healthcare runs on fragmented data. Patient records, coverage policies, and clinical evidence remain trapped across disconnected records, claims systems, and administrative tools that don’t work together. …

Fact-Checking at Scale: Building a More Accurate and Efficient Synopsis Factuality System

By Shreya S Ramanujam, Yongce Li, Afshine Amidi, Sina Ghiassian, Benjamin Klein. Introduction Picture this — you’re home after a long day at work and can’t wait to catch up on Bridgerton. You log on to Netflix, search for “Bridgerton” and land on this screen: If this sounds familiar, you already know what a synopsis is — it’s a short glimpse …
