DOJ probes a16z over seats on rival AI boards

The Justice Department has spent nearly a year looking at the most ordinary thing a venture firm does: putting partners on boards. Andreessen Horowitz is the focus of a Justice Department antitrust probe over whether its investment partners are improperly serving on the boards of competing AI companies, according to people familiar with the matter. The investigation, which had not been previously reported, is nearly a year old. Among the companies at issue are Databricks — one of the world's mo

Google pays $10M for a dead airline's training data

When the open web runs dry, bankruptcy court starts to look like a data vendor. Google won a $10 million auction for the deidentified business data, software code, and operations records of collapsed low-cost carrier Spirit Airlines, and it says the haul will help improve its products and AI models. An August 14 notice in the US Bankruptcy Court for the Southern District of New York describes a private corpus no crawler could have built: 100 million emails, 500 million Microsoft Teams chats and

CNCF graduates Kubeflow for production AI on Kubernetes

The cloud-native world just put an official stamp on how enterprises are supposed to run AI on Kubernetes. After nine years of community work and three years in incubation, Kubeflow is no longer the side project next to the cluster — it is the platform CNCF is willing to graduate. The Cloud Native Computing Foundation graduated Kubeflow on Monday, calling it a mature, production-ready platform for the full data and AI lifecycle on Kubernetes. The August 17 announcement is the same maturity rung

Groq raises $350M at $3.5B, half its 2025 value

The inference market just got a reality check, and Alibaba's Qwen team quietly shipped an open-source tool that wants to remember how you work. Groq has closed a $350 million round at a $3.5 billion valuation — roughly half the $6.9 billion it commanded in September 2025, before Nvidia struck a licensing deal and poached much of its talent. Bloomberg, citing people familiar with the matter, reports the round was led by Disruptive, and that the markdown reflects how the chipmaker's own moves res

AI's new kingmakers: chip giants poured $250B into startups in 2026

The AI boom has minted a new class of power broker, and it isn't the labs shipping the models. It's the companies selling the silicon everyone else runs on — and they've started writing the checks themselves. Semiconductor giants have become AI's most aggressive venture capitalists, taking part in startup rounds collectively valued at more than $250 billion so far in 2026, according to Crunchbase data — a multiple of any prior yearly high for the sector. Nvidia alone has participated in a reco

A humanoid robot drove a go-kart to test 'whole-body intelligence'

The push to make humanoid robots genuinely useful took an unusual detour today: a Chinese startup strapped one into a go-kart. Symbiosis Robotics (共生知行) put a bipedal humanoid into a go-kart's driver's seat, and the machine drove a closed-circuit lap — hands on the wheel, feet working the pedals, body braced against the lateral load of a cornering kart. The company says the point was never the racing. Driving packs perception, balance, and fine motor control into one continuous task: the robot

Wispr hits $2B in a Menlo-led round to outgrow dictation

Two signals that AI is moving from clever demos to durable categories: money piling into voice interfaces, and open-source tooling for running agents safely inside companies. Voice AI startup Wispr raised $280 million in a Series B led by Menlo Ventures at a $2 billion valuation, and it's positioning itself as far more than a dictation app. The round brings total funding to $361 million and lands as the company claims 100,000 business customers. Wispr made its name with a fast, hands-free dicta

HiDream-O1-World tops an interactive world-model benchmark

World models keep crossing out of the research demo into something you can actually steer — and the newest one to break the frontier comes from a Chinese lab better known for image generation. ZhiXiang WeiLai's HiDream-O1-World is an interactive, native all-modal world model, and its first trip onto a public benchmark just put it at the top. HiDream-O1-World, the interactive world model from Chinese lab ZhiXiang WeiLai (the HiDream image-model maker), topped the Navi ranking of WBench — the new

**Instabase relaunches as SuperApp to move AI into team work**

Instabase relaunches as SuperApp to move AI into team work Instabase, the unstructured-data company that has raised more than $250 million since 2015, is rebranding as SuperApp and shipping a flagship work platform built around team collaboration with AI models. The new app pairs a Slack-style communication interface with a Google-Docs-like document library and deep access to models from OpenAI, Anthropic and Google — with routing that picks the right model for each task so users don't have to

Big Tech's hidden $3T in AI obligations dwarf reported capex

The AI buildout's bill just got a lot bigger — and most of it was never on the books. A Wall Street Journal analysis of nine top tech companies found roughly $3 trillion in AI-related off-balance-sheet commitments, far exceeding the roughly $600 billion those same companies reported as capital expenditure. The gap tells you something about how this boom is being financed, and how exposed investors may be. A WSJ analysis found nine top tech companies carry ~$3 trillion in AI-related obligations

HelixWorld adds real-time sound to interactive AI worlds

World models have grown eerily good at rendering explorable scenes in real time — and just as eerily mute. Noiz AI, backed by researchers from Hong Kong University of Science and Technology, Tsinghua, Carnegie Mellon and Google DeepMind, is the team that finally filled the silence in. Noiz AI released HelixWorld 1.0, a real-time interactive audio-visual world model that generates 24 FPS video and 48 kHz stereo audio together. Drop in an image and a prompt and the model renders a world you can w

AI film startups open their own Hollywood studios

The AI video boom is going physical: startups that used to make clips on demand are now planting flags in Hollywood itself. Meanwhile, a Peking University research push is quietly attacking the one bottleneck that makes chatty models feel sluggish — the wait for the first word. AI film startups are setting up studios in Hollywood, using both US and Chinese models to cut production costs and route around traditional financing. The Guardian reports a wave of AI-native film companies moving onto a
