How Bayer Crop Science built an agentic decision engine on Amazon Bedrock AgentCore with AWS Unified Operations

  • ADE provides a natural-language multi-agent interface over CDE, with a supervisor routing requests to 22 specialist agents and resolving about 80% of user questions without an engineer in phase one.
  • The architecture combines React, Entra ID, LangGraph, AgentCore Runtime and Gateway, DynamoDB, Aurora, ElastiCache, S3, OpenSearch Serverless, and CloudWatch, separating session isolation from durable orchestration state.

Multi-Turn Reinforcement Learning on Amazon SageMaker AI: A hands-on guide

  • MTRL rewards the final outcome of an entire multi-step episode, suiting agentic tasks where there is rarely one correct trajectory to imitate.
  • In the authors' run, MTRL raised gpt-oss-20b's solve rate on held-out words from 61% to 84% at default reasoning effort and from 15% to 69% at low effort, for about $339 in training tokens.

At MIT, Martha Minow speaks on sustaining democracy, both by using and overcoming AI

  • Minow identified education, trustworthy information, safety from violence, and fairness as democracy’s core ingredients, and said AI is stressing each.
  • She warned that dominant AI platforms can deepen passivity and weaken critical thinking, especially among young people, but said tutor-like systems could encourage deeper inquiry.

Blue Planet III features cloudier footage to prove authenticity amid AI boom

Producers of the BBC's David Attenborough-narrated Blue Planet III say the series deliberately includes cloudier, less polished shots to counter AI fakery and reassure viewers that what they are seeing is authentic. The series returns nearly a decade after Blue Planet II highlighted plastic pollution.

Now Google says it might use your Gmail and Google Photos data to target ads

Google updated its privacy policy to add an exception to its promise not to use Drive, Gmail, or Google Photos data for personalized ads when users connect those services to personalized AI features. Advertisers don’t get the data or identifying details, and users can disconnect apps or disable personalized recommendations.

Opposition deepfake video sparks outrage in Spain ahead of election

Spain's conservative People's party published a social media ad using AI to fabricate the likenesses of people linked to Prime Minister Pedro Sánchez's Socialists, including the prime minister's wife, appearing to admit to wrongdoing. The video has drawn outrage and fuelled a wider debate about AI a month before general elections.

Orchestrating SageMaker AI endpoint auto scaling with AWS CDK

The AWS Machine Learning Blog explains why updating a SageMaker AI real-time endpoint with Application Auto Scaling registered breaks CloudFormation/CDK deployments. It provides a reusable CDK construct that uses custom resources to deregister and re-register scaling in the correct order, enabling endpoint and scaling updates in one deployment.

Quick Study

Simon Willison released Quick Study, a browser tool that uses a canvas element and simulated paintbrush to rapidly repaint an uploaded photo in a painterly style. The artifact was built with Claude Opus 5.5 High from a single prompt and uses Sobel edge detection with no external libraries beyond Google Fonts.

Jack Dorsey’s Block made an AI model that talks to you like an awkward new friend

Block has unveiled Dessa, a speech-to-speech AI model it says was trained from scratch only on human conversation. Demo clips show mostly natural but sometimes awkward exchanges; the model can run locally on a MacBook Pro M4 Max or better, and early access will go to a small group of AI safety researchers.

LLM Inference Explained: How Models Generate Responses Faster

This guide breaks down how large language model inference actually works: tokenization, the compute-bound prefill stage, and the memory-bandwidth-bound decode stage, plus how the KV cache lets models reuse prior context. It explains why inference slows down with long contexts, large batches and concurrent users, which metrics (TTFT, TPOT, throughput, p95/p99 latency) actually matter, and how quantization, FlashAttention, continuous batching, PagedAttention, tensor parallelism and speculative decoding each target a different bottleneck.
