FL-MAESTRO: Multi-Agent LLMs Orchestrate Federated Learning Decisions

FL-MAESTRO introduces a multi-agent orchestrator that uses three specialist LLM agents to jointly determine communication topology, resource allocation, and aggregation rules during federated learning. Unlike prior approaches that focus on setup-time configuration or single runtime dimensions, this system adapts to dynamic network conditions where edge devices drop in and out. A coordinator agent synthesizes the outputs of the specialist agents to make these coupled decisions in real time.

  • Multi-agent LLMs handle coupled FL decisions: topology, resource allocation, and aggregation.
  • Adapts to runtime variability as edge devices join or leave the network.
  • Moves beyond setup-time configuration to dynamic, real-time orchestration.
  • Specialist agents each manage one decision dimension, coordinated by a central agent.

Google HEIR Compiler Turns LLMs into One-Click Homomorphic Inference

Google has released HEIR, an open-source toolchain that compiles pre-trained AI models to operate directly on encrypted data. This intermediate representation allows developers to take standard inference pipelines and adapt them for homomorphic encryption without rebuilding from scratch. The goal is to lower the barrier for deploying privacy-preserving machine learning in production environments.

  • HEIR compiles existing models to support encrypted inputs, reducing integration friction.
  • Open-source toolchain targets developers needing privacy-preserving AI inference.
  • Enables homomorphic encryption capabilities without requiring custom cryptographic code.
  • Simplifies deployment of secure LLMs for sensitive data processing workloads.

AWS Cost Anomaly Detection now covers third-party models on Bedrock

AWS Cost Anomaly Detection has expanded its monitoring capabilities to include spend on third-party foundation models hosted on Amazon Bedrock, such as Anthropic Claude. This update applies automatic anomaly detection to generative AI workloads without requiring additional setup, integrating Bedrock costs into the existing AWS managed service monitor. Users receive alerts and root-cause breakdowns when model usage deviates from expected patterns.

  • Monitor spend on third-party models like Claude on Bedrock using existing Cost Anomaly Detection tools.
  • No configuration required; coverage is automatic for AWS managed service monitors.
  • Receive alerts and dollar-impact root-cause analysis for unexpected model usage spikes.
  • Integrates GenAI costs into broader AWS cost management alongside other services.

DoorDash Cuts LLM Costs with Hybrid AI Moderation at Scale

DoorDash replaced expensive LLM-only moderation pipelines with a hybrid architecture that filters obvious cases using fast internal models before engaging LLMs for nuanced, multi-axis scoring. The system leverages no-code workflows and backtesting to manage content-agnostic safety rules efficiently. This approach successfully scales to millions of daily messages while reducing safety incidents and operational costs.

  • Hybrid filtering reduces reliance on costly LLMs for clear-cut cases.
  • Multi-axis scoring handles nuanced moderation decisions accurately.
  • No-code workflows simplify rule management and iteration speed.
  • Backtesting validates model performance before production deployment.

SageMaker AI Studio adds visual Generative AI Inference Recommendations

Amazon SageMaker AI Studio now includes a guided, low-code interface for Generative AI Inference Recommendations, extending the API-based capability launched in April 2026. This feature uses the same benchmarking infrastructure to help teams identify optimal instance types, serving containers, and optimization strategies without manual trial-and-error. Users can define workload requirements for metrics like latency to receive tailored configuration suggestions.

  • Visual workflow replaces manual benchmarking for inference configuration tuning
  • Extends April 2026 API functionality to non-programmatic SageMaker AI Studio users
  • Reduces weeks of trial-and-error by recommending optimal instance and container combos
  • Allows workload-specific prioritization for metrics like latency and throughput
