Workers - WebSocket binary messages now delivered as Blob by default

Binary frames received on a WebSocket are now delivered to the message event as Blob objects by default. This matches the WebSocket specification and standard browser behavior. Previously, binary frames were always delivered as ArrayBuffer. The binaryType property on WebSocket controls the delivery type on a per-WebSocket basis. This change has been active for Workers with compatibility dates on or after 2026-03-17, via the websocket_standard_binary_type compatibility flag. We should have docume

AI and the Future of Cybersecurity: Why Openness Matters

Build Google ADK Agents with persistent, real-time memory on Redis

Google’s Agent Development Kit (ADK) delivers clean abstractions for building AI agents. It defines interfaces for memory, sessions, tools, and callbacks. But the default implementations store everything in process memory, which means the state disapp...

Startup Spotlight: Neuron Systems keeps AI personalities consistent across NFL and cricket with Redis

Most AI systems don’t have a memory problem. They have a retrieval problem. Under real load, they can’t access what they know fast enough to matter. Neuron Systems built a multi-agent debate platform for sports content creators. Six distinct AI perso...

Approaches to tenancy in Postgres

We've updated our use of the term "row-level isolation" to "shared-schema" in this article to avoid confusion with Postgres RLS.We do not recommend relying on Postgres RLS. Multi-tenancy is a term used across various kinds of technical infrastructure, including application hosting, compute, databases, and more. For example, you may purchase cloud services from a provider, but your account is one of many that draws from a common pool of resources. Your account is one "tenant" in a multi-tenant in

Maximizing Memory Efficiency to Run Bigger Models on NVIDIA Jetson

The boom in open source generative AI models is pushing beyond data centers into machines operating in the physical world. Developers are eager to deploy these models at the edge, enabling physical AI agents and autonomous robots to automate heavy-duty tasks. A key challenge is efficiently running multi-billion-parameter models on edge

Run High-Throughput Reinforcement Learning Training with End-to-End FP8 Precision

As LLMs transition from simple text generation to complex reasoning, reinforcement learning (RL) plays a central role. Algorithms like Group Relative Policy... As LLMs transition from simple text generation to complex reasoning, reinforcement learning (RL) plays a central role. Algorithms like Group Relative Policy Optimization (GRPO) power this transition, enabling reasoning-grade models to continuously improve through iterative feedback. Unlike standard supervised fine-tuning, RL training loop
