StackGen puts one governance plane under every production agent

Coding agents made change volume explode. Operations absorbed the blast without a comparable upgrade — and StackGen's answer is to stop bolting agents onto four silos and put one operating system underneath all of them. StackGen launched its Autonomous Operations Factory on Tuesday, a control plane that runs infrastructure, DevOps, observability and reliability agents against a single shared model of what is deployed, what changed, what broke and what fixed it. The foundation is Aiden OS, which

Salesforce and Nvidia ship Koa, a reasoning model for Agentforce

Two stories on the same question this afternoon: what happens to frontier-lab pricing when the enterprise stack stops renting reasoning by the token. Plus a security layer for the robot fleet. Salesforce debuted Koa, a reasoning model it built with Nvidia on top of the open-weight Nemotron base, and says it will handle the multi-step thinking inside Agentforce that used to be sent out to Claude or ChatGPT. Jayesh Govindarajan, Salesforce's EVP of AI, put it plainly: the company had built many s

Agility's Digit 5 drops the cage around the humanoid at work

Two infrastructure stories this afternoon — one about robots that stop needing fenced-off floors, one about data centers that stop needing years of construction. Agility Robotics unveiled Digit 5, a humanoid engineered to work next to people without physical barriers, and the bet is that certification, not capability, is what scales robots. The company says the robot watches for humans across a full 360-degree field, evaluates the risk as someone approaches, then slows, stops, or sits down and

Honor ships the first phone with a system-level agent harness

Two stories from the Chinese AI beat this morning, one about where the agent runs and one about what it can simulate. Honor unveiled MagicOS 11 today with what it calls the industry's first commercially deployed system-level Agent Harness, and the numbers behind it are bigger than the label. Its YOYO assistant now strings together more than 100 steps in a single instruction, with roughly 700 system tools it can call — nearly double the previous set — and more than 500 third-party Skills already

Google DeepMind safety researcher quits, says AI 'could kill us all'

The pacing fight just picked up a witness from inside Google's lab, Britain's government put itself on record about listening, and someone finally ran the accounting on what the data centers have to earn back. Google DeepMind's AGI safety team produced its first public exit note, and it landed in the middle of the industry's loudest argument. Bilal Chughtai, who worked on safety and alignment research at DeepMind until July, posted this week that he "earnestly believe[s]" AI has the potential t

MediaTek's 2nm chip puts a 30B MoE model on your phone

The edge is the story today: new silicon built for agents, an OS safety suite that runs its models on the device, and a fresh open model betting on spatial reasoning — all landing within hours of each other. MediaTek launched the Dimensity 9600 Pro, a TSMC 2nm flagship whose headline spec is an agent, not a benchmark. The chip pairs a dual-NPU design with an "Agentic AI Engine" and a second-generation efficiency NPU fused to a low-power sensor hub — a 40% cut in always-on AI power that is what

Open Source Radar — September 15: agents get eyes and a voice

Today's board is about what sits between an agent and everything else: the hookup to the live internet, the voice it speaks with, and the box it runs in when there is no network at all. Agent-Reach (Python, 81,783 stars, MIT) — A capability layer that gives any command-running agent read and search access to the platforms where the useful information actually lives: X, Reddit, YouTube, GitHub, Bilibili, XiaoHongShu, RSS. Each platform gets an ordered list of backends — a primary plus fallbacks

StepFun ships five voice models and takes two global No. 1 spots

A Chinese lab just shipped the whole voice stack in one afternoon — and the pacing fight in Washington got a very public answer from Nvidia's CEO. StepFun released five StepAudio 3 models on the same day, and two of them now sit at the top of Artificial Analysis's speech leaderboards. StepAudio 3 Realtime, ASR, TTS, Gen and Music went live on StepFun's open platform Tuesday, covering everything from full-duplex conversation to music generation. The company claims 98.9 overall on the Artificial

Deep Dive — Google lets Claude inside. The quota is the whole story

Google has given every one of its engineers access to Anthropic's Claude Opus 5 inside Antigravity, its agent-first development platform, according to Business Insider's report on Tuesday, sourced to two employees. A Google spokesperson said "Gemini remains our primary and foundational model for internal development, with third-party models available on a quota to support specialized use cases." DeepMind teams have had Claude access for some time, and individual employees had negotiated it for h

Google lets every engineer use Claude Opus 5 inside Antigravity

Rivals keep trading places today: Google opens its doors to Anthropic's best coding model, a Chinese lab sweeps the voice leaderboards, and SemiAnalysis maps where a robot's brain should live. Google has given staff across the company access to Anthropic's Claude Opus 5 for internal work — but only inside Antigravity, Google's internal version of its development platform, according to Business Insider's report. A Google spokesperson said "Gemini remains our primary and foundational model for in

Euclyd raises €200M for a European answer to Nvidia's inference grip

Euclyd, an Eindhoven chip startup founded in 2024, closed a Series A of more than €200 million (about $231 million) co-led by Samsung, Somerset Capital Partners, the EQT-managed Scaleup Europe Fund and Innovation Industries, the company announced on September 15. Rounding out the syndicate are EIFO, imec.xpand, the Brabant Development Agency and Quadri. The board appointment matters as much as the money: Peter Wennink, the former ASML president and chief executive who spent more than a decade tu

AI 101 — What is backpropagation?

Backpropagation is the algorithm that lets a neural network learn from its mistakes: it measures how wrong the model's answer was, then works backwards through the network to figure out how much each individual connection contributed to that error. Once it knows who is responsible, the model nudges each connection a little in the direction that would have made the answer less wrong. Do that billions of times and you get a language model. Almost every claim you read about AI training — a model "
