RA3 presents a scalable mid-training RL framework that learns compact action abstractions via a sequential variational objective to prune the action space, accelerate convergence, and boost post-training reasoning performance across code-generation and multimodal grounding tasks.

Exai Bio and Databricks demonstrate AI-powered, multimodal liquid biopsy for early cancer detection, detailing Exai-1 and Orion foundation models for cfRNA and oncRNA signals, unified on a Databricks Lakehouse with scalable compute and MLflow-based MLOps to enable reproducible, cross-cohort training across thousands of patient samples.

Databricks SQL 2025 delivers automatic, no-tuning performance gains across dashboards, pipelines, governance, and AI workloads, powered by serverless, Unity Catalog, Delta Sharing, and intelligent engine optimizations like Predictive Query Execution, while reducing storage costs with Zstandard by default.

Lambda joins the Open Compute Project Advisory Board to accelerate open, composable AI infrastructure that decouples power delivery and cooling from compute for scalable, repeatable deployments.

Explores whether LLMs can reveal their internal answer distributions, introduces the SelfReflect metric to gauge faithfulness between summaries and beliefs, and shows that explicit uncertainty requires sampling multiple outputs to be truly transparent.
