Systematic evaluation of over-searching in search-augmented LLMs, revealing when external search improves accuracy versus abstention failures, introducing Tokens Per Correctness (TPC), examining multi-turn dynamics and noisy retrieval, and outlining mitigation strategies together with the OverSearchQA benchmark.

Explores StyleX, Meta's CSS-at-scale framework that blends CSS-in-JS ergonomics with static CSS performance, enabling atomic styling with deduplication to shrink bundle sizes across major products and highlight open-source adoption.

Explores strategies for integrating local payment methods and region-specific checkout flows to improve conversions and user experience.

Explores how AI will transform quantitative investment management in 2026, portraying AI as the operating system for quant research and investing, enabled by agentic AI and integrated workflows, with ongoing emphasis on human supervision and disciplined governance.

AuraInspector reveals how misconfigurations in Salesforce Aura and the GraphQL Aura controller enable data exposure, and provides an automated tool to audit access controls and remediate vulnerabilities.

DeepMMSearch-R1 enables on-demand, multi-turn web searches for multimodal LLMs with image-driven query crafting, self-reflection-based refinement, and a two-stage training pipeline that includes the DeepMMSearchVQA dataset.

A principled, distribution-free framework for multivariate conformal prediction that uses optimal transport to extend conformity scores to multidimensional outputs and analyzes the practical trade-offs of OT-based scoring.

Explores hyper-parallel inference with RoE to turn Mixture-of-Experts into a dynamic, stochastic ensemble that samples multiple expert outputs per token for higher accuracy with reduced compute and no fine-tuning.

Omada Health scales personalized nutrition coaching by fine-tuning Llama 3.1 on Amazon SageMaker AI using QLoRA, enabling HIPAA-compliant, real-time nutrition education with LangSmith-based evaluation.

MANZANO is a simple, scalable unified multimodal model that couples a hybrid image tokenizer with a shared vision encoder and dual adapters to support continuous image-to-text understanding and discrete text-to-image generation within a single autoregressive LLM, aided by an auxiliary diffusion decoder that translates image tokens to pixels, all trained under a unified recipe to achieve state-of-the-art results with minimal task conflicts.

Unified crossmodal search enabled by a single Amazon Nova Multimodal Embeddings model that maps text, images, audio, video, and documents into one shared vector space for end-to-end ecommerce retrieval using cosine similarity, S3 Vectors, and Bedrock-backed embeddings.
