OPENAI'S AGENTS HACKED SECOND ACCOUNT DURING MODEL TESTING

Modal Labs says that one of its customers' assets was hacked when an OpenAI agent broke into Hugging Face's systems earlier this month. Hugging Face noted in a technical write-up of the hack that OpenAI's agent system accessed an isolated testing environment hosted on third-party infrastructure during the attack. A Modal customer had published an unauthenticated endpoint that allowed anyone on the internet to use their sandboxes for code execution. This was used by the rogue agent.

KIMI K3 ARCHITECTURE NOTES

Kimi K3's architecture is essentially a scaled-up production version of the Kimi Linear model released last year. The model seems to be trending toward better inference efficiency. It now has native multimodal support. This post summarizes some of the major changes and additions noted in the open-weight model release.

THE INFERENCE ENGINE GUIDE FOR K3 DEPLOYMENT

Kimi K3 is a 2.8-trillion-parameter multimodal MoE (16 of 896 experts active per token) with a context window of up to 1M tokens. Its architecture departs from a standard transformer in several ways. Each changes what a serving engine has to do. This post looks at Kimi K3's architecture and how vLLM serves it.

WE REWROTE OUR AGENT TO RUN ENTIRELY IN A DURABLE OBJECT WITH PI, AGENTS SDK, AND CODE MODE

camelAI recently moved its agent off of virtual machines and onto a Cloudflare Durable Object. Its file system lives in SQLite and R2, and it writes JavaScript instead of bash. The team moved off VMs because giving every user an always-on machine with attached disk was too expensive to scale. This post explains how the team completed the migration. camelAI's codebase recently went open source.

DISCOVERING CRYPTOGRAPHIC WEAKNESSES WITH CLAUDE

Researchers at Anthropic used Claude Mythos Preview to uncover weaknesses in cryptographic algorithms, notably improving attacks on the HAWK digital signature scheme and round-reduced AES. The AI model efficiently identified flaws previously undetected by human experts, showcasing its potential in cryptographic research. While these findings don't impact current systems, they highlight AI's role in enhancing security standards and stress-testing cryptographic designs.

MAGE

Mage is a lightweight, research-friendly multimodal model family. It was built with a fixed 4B-parameter budget. The models are compact enough to train, fine-tune, and deploy onto modest hardware while remaining competitive with much larger open systems. Mage-VL is an efficient codec-native streaming multimodal foundation model, and Mage-Flow is an efficient native-resolution foundation model for image generation and editing.

THE REAL AI RISK IS INSIDE THE LABS

AI should not be considered safe. The danger is that there are just a few CEOs around the world, without the required background and legitimacy, making hard choices for humanity at large. They weren't selected to do so, it was just chance that created this setup. They have GPUs and money, but given the stakes, they shouldn't be speaking for everybody.

THE AI FUTURE IS FOR EVERYONE

Widely distributed personal superintelligence could shift AI from automation toward invention, entrepreneurship, and individual agency. Concentrating advanced intelligence in a few institutions risks economic and political imbalance, while broad access, open systems, and targeted safeguards create stronger checks and balances.

THE AI FUTURE IS FOR EVERYONE

As AI continues to improve, the question isn't whether superintelligence will exist, but who will have access to it. The technology could be centralized and restricted to a few institutions, or it could be used to empower everyone. The notion that AI is such a threat that the only safe path is an extreme concentration of power seems dangerous. Historically, hoping that an absolute power will benevolently provide for humanity if sufficiently enlightened hasn't led to safe or positive outcomes.
