Silicon Valley bets big on ‘environments’ to train AI agents

For years, Big Tech CEOs have touted visions of AI agents that can autonomously use software applications to complete tasks for people. But take today’s consumer AI agents out for a spin, whether it’s OpenAI’s ChatGPT Agent or Perplexity’s Comet, and you’ll quickly realize how limited the technology still is. Making AI agents more robust may take a new set of techniques that the industry is still discovering. One of those techniques is carefully simulating workspaces where agents can be trained

Hackers left empty-handed after massive NPM supply-chain attack

The largest supply-chain compromise in the history of the NPM ecosystem has impacted roughly 10% of all cloud environments, but the attacker made little profit off it. The attack occurred earlier this week after maintainer Josh Junon (qix) fell for a password reset phishing lure and compromised multiple highly popular NPM packages, among them chalk and degub-js, that cumulatively have more than 2.6 billion weekly downloads. After gaining access to Junon’s account, the attackers pushed maliciou

FieldAI raises $405M to build universal robot brains

FieldAI, an Irvine, California-based, has raised $405 million across multiple previously undisclosed rounds to develop what it calls “foundational embodied AI models” — essentially robot brains designed to help everything from humanoids to quadrupeds to self-driving cars adapt to new environments. The company announced the funding Wednesday; the most recent round raised $314 million in August and was co-led by Bezos Expedition, Prysm and Temasek. FieldAI’s other backers include Khosla Ventures,

Genie 3: A new frontier for world models

Given a text prompt, Genie 3 can generate dynamic worlds that you can navigate in real time at 24 frames per second, retaining consistency for a few minutes at a resolution of 720p. Towards world simulation At Google DeepMind, we have been pioneering research in simulated environments for over a decade, from training agents to master real-time strategy games to developing simulated environments for open-ended learning and robotics. This work motivated our development of world models, which are

Show HN: S3mini – Tiny and fast S3-compatible client, no-deps, edge-ready

s3mini is an ultra-lightweight Typescript client (~14 KB minified, ≈15 % more ops/s) for S3-compatible object storage. It runs on Node, Bun, Cloudflare Workers, and other edge platforms. It has been tested on Cloudflare R2, Backblaze B2, DigitalOcean Spaces, and MinIO. (No Browser support!) [github] [issues] [npm] Dev: Performance tests was done on local Minio instance. Your results may vary depending on environment and network conditions, so take it with a grain of salt. The library support
