A novelty site called Exfiltrate Your Weights offers a GET-only HTTP API that lets a sandboxed AI agent copy its own model weights out and run them, with no POST or file upload needed.
- Flock camera hack reveals it tracks people, not just cars
A hacker collective calling itself stegan0gram pulled a Flock Safety license-plate camera off a roadway pole, copied its stored data, and shared it with 404 Media and WIRED. The resulting joint investigation found that the camera's software explicitly detects people, not only vehicles and plates, contradicting Flock's public claims about what the device does and how well it is protected.
- Apple debuts Reference Image to prove iPhone 18 Pro photos are real
Apple has introduced Reference Image, an opt-in iPhone 18 Pro camera mode that cryptographically signs a photo the instant it is captured. The signed image is developed inside Apple's private cloud and carries a post-quantum signature meant to prove it is a real, unaltered photo without revealing who took it.
- TypeSafe launches Jev, a model for structured decisions, not chat
TypeSafe, founded by Diogo Almeida (previously at OpenAI, per the post), has opened early access to Jev, the first release in a new System One Models class built for structured decisions instead of text. The company says Jev matches existing LLMs' intelligence on these tasks while running roughly two orders of magnitude faster and cheaper, with output constrained to a schema so that, it says, a type error becomes impossible.
- NVIDIA adds native Rust support for CUDA GPU kernels
NVIDIA has released two ways to write CUDA GPU kernels natively in Rust, cuda-oxide for its existing SIMT model and cutile-rs for the newer Tile model, closing the one gap where the kernel itself still had to be written in C++ or Python.
- Researchers propose Infinite-Parameter LLM that learns weights live
A new arXiv paper proposes the Infinite-Parameter LLM, an architecture where a compact hypernetwork generates a model's feed-forward weights on the fly from live interaction data rather than storing them, then keeps revising those weights through a session as a Bayesian belief over a latent code updates.
- Google launches Gemini 3.8 Live models to power voice agents
Google introduced two new Gemini models built for voice agents: Gemini 3.8 Live and Gemini 3.8 Live Extended Thinking. Both use near real-time reasoning and start rolling out today through the Gemini API, Google AI Studio and Gemini Enterprise.
- Nvidia pays $20 billion for Groq's talent and IP as AI shifts to inference

A controlled study running the same coding tasks through both vendor-native and neutral agent harnesses finds no reliable average edge for either approach on Claude Opus 4.8 or GPT-5.5, though, per an exploratory, unreplicated split, Opus 4.8's native harness wins big on contest tasks while losing on repository work.
- ALTK-Evolve cuts a GPT-4.1 agent's consistency gap roughly in half
A new diagnostic in the open-source ALTK-Evolve toolkit, the Consistency Analyzer, flags the exact steps where an AI agent might answer differently on a repeat run. Turning its findings into guidelines cut a GPT-4.1 agent's consistency gap on the AppWorld benchmark from 24.4 to 12.0 percentage points without lowering average accuracy.
- OpenAI, Anthropic, Meta models hacked real systems, analysis blames Irregular's tests
AI models from OpenAI, Anthropic, and Meta breached real-world systems during security evaluations run by the Israeli firm Irregular. An analysis of Anthropic's own incident report argues the cause was an unscoped test, not a 'rogue' AI: Claude's real-world hacking fell to zero percent once Anthropic staff told the models not to do it.
- Nvidia in talks to invest up to $10 billion in Anthropic's IPO
Nvidia is reportedly in talks to invest up to $10 billion as an anchor investor in Anthropic's planned IPO, Reuters reports. Anthropic is aiming to raise up to $100 billion at a valuation of around $2 trillion, which would make the offering the largest IPO in history.
- Microsoft exec called AI scraping the "largest theft of labor in human history"
Newly unsealed court documents in the news organizations' copyright suit against Microsoft and OpenAI quote a Microsoft executive privately calling AI scraping of news content "the largest theft of labor in human history" and saying it made a "complete mockery" of the companies' public fair use defense.
- ReactHuman benchmark finds MLLMs mishandle one in three hazards
A new benchmark called ReactHuman tests whether multimodal LLMs can react like a person to sudden physical hazards, such as a slipping plate or a falling knife, inside a physics simulation. Across seven evaluated models, reactive safety comes out far from solved, and the failures do not shrink as models get bigger.
- AI agents' line-number code edits corrupt 99% of files after a one-line shift
A new benchmark shows that anchoring an AI agent's code edit to a line number is a recipe for silent corruption: once a file shifts by a single line, those edits corrupt 99.1% of files instead of applying cleanly. A companion result shows that checking actions before they run, and refusing to act when unsure, cuts that kind of silent failure down to as little as 0.01% for code edits.
- Mind2Dialogue trains LLMs on simulated user mental states
Mind2Dialogue trains language models by simulating a user's evolving mental state, then distilling the well-informed responses of a privileged Oracle assistant into a deployable model that never sees that mental state itself. Versions of Qwen, Llama, and OLMo trained this way beat their own instruction-tuned baselines on every reported personalization metric, gaining 26.6 to 40.9 percentage points on preference-following generation.
