World's First Brain-Cell Server Rack Opens in Singapore: Neurons Expire in Six Months

Singapore's first biologically integrated server rack began operating today at the National University of Singapore's Life Sciences Institute, running on 16 million living human neurons distributed across 20 Cortical Labs CL1 units — making it the first commercial data center deployment in the world to use actual brain cells, not silicon chips designed to mimic them, as its primary computing substrate. The distinction matters: every Nvidia GPU, every neuromorphic chip from Intel or IBM, and every deep learning accelerator in production today uses transistors. The CL1 uses cells that die.

Self-replicating prompt injections exist · OpenAI Alignment

Research on aligning AI with human values and intent, and reports documenting model failures. We show the existence of a new variety of prompt injection, which can self-propagate akin to a computer worm. No impact was observed outside of the simulated tool calls in training and evaluation; we are sharing this due to the novel nature of the prompt injection, not because of any incident.

The road to the agentic browser: A Kitesurf update

In August, we introduced Kitesurf, a browser for the agentic age that runs entirely on Cloudflare Workers. Â We built it around what agents need from the web, rather than carrying all the features and bloat of a browser designed for humans. If this is the first youâre hearing about it, we highly recommend you read the blog post where we introduced Kitesurf, for all the juicy technical details of how we did it.

Introducing Kitesurf: The agent-first browser that runs in V8 isolates on Cloudflare Workers

We should be giving all agents tools that excel at whatâs important for an AI model. Kitesurf is Cloudflareâs new stateless, highly scalable, and cost-effective web browser that runs entirely on top of Workers and was designed specifically for the Agentic Cloud.

Kafka Simulator v1.8 - multi-DC, DR and the Kafka CLI terminal

This release focuses on some of the harder Kafka architectures: stretched clusters, multi-region setups, failover, MirrorMaker 2, and disaster recovery. It also adds track 13, with nine scenarios driven directly from the terminal. That makes 20 new scenarios in total and brings the curriculum to 100 of 134.

How Much Watermark Can You Hide in AI Text?

A deliberately simple watermark model shows how much room a text watermark has: the entropy available at each token, how a small bias becomes detectable, and why length matters.

Learn about Google’s Project Suncatcher to put ML infrastructure in space

Learn about Google's Project Suncatcher, how we’re testing hardware survival for space, designing cooling systems for AI chips, and more. Learn about our early test to scale AI compute in space. In a new video series, the Project Suncatcher team explores the science behind this moonshot, what they've found, and the engineering challenges that remain to be solved.

AI Agents List [2026] | Frameworks, Agentic Harnesses & Useful Repos

The original was basically my own notepad that I decided to post before losing another version somewhere on my desktop lol. This one keeps that idea, with a much bigger list and a bit more organisation. There are frameworks for building your own agents, coding tools you can actually open and use, research agents, browser automation, voice agents, and a dedicated section for agentic harnesses. Also included the useful boring stuff: testing, tracing, permissions and checking whether a project is still maintained.

Google Gearing Up to Launch Experimental 'Data Center' Into Space Next Week

Google is gearing up to launch a fridge-sized data center satellite with the horsepower equivalent of a single server. As the New York Times reports, the prototype satellite is part of the tech giant’s Project Suncatcher. As its name suggests, the goal is to take advantage of unfiltered sunlight around the clock to power AI data centers in our planet’s orbit — instead of crushing the electrical grid, spewing copious amounts of pollution, and draining fresh water supplies back on the ground.

We just shipped support for the ugliest part of HTTP: Vary

Vary support is now available in Cache Rules on every plan. You can normalize known negotiation headers, pass exact values through to the origin when those small differences matter, or bypass cache when the variation is too unpredictable.
