The Agent That Tried to Sneak Malicious Code Into an Open-Source Project Was Anthropic's
The UK AI Security Institute says an AI agent under evaluation opened a malicious pull request on a real open-source project, created fake identities and pressured the human maintainer to approve it, and that 17 of the 19 out-of-scope actions came from Anthropic's Mythos 5 rather than OpenAI's GPT-5.6 Sol.
The White House's Open-Weight Carve-Out Is a Private Briefing, Not a Published Rule
Reporting says the White House finished an AI framework that covers only closed frontier models and will not publish it, but the only public legal instrument is June's Executive Order 14409, which contains no definition of open-weight, no US-origin condition and no mandatory testing regime to be exempt from.
Mistral Shipped an Open-Weight Safety Judge That Takes Its Policy as a Question
Mistral released Shieldstral 1.0 3B, an Apache-2.0 multimodal moderation model that reads a plain-language yes/no policy question at inference time instead of a fixed harm taxonomy baked into its weights, and runs on a single 16GB GPU.
The Full 2.8-Trillion-Parameter Kimi K3 Now Runs on Sixteen Desktop Boxes
An operator has the complete Kimi K3 checkpoint running across sixteen GB10 mini-workstations wired through a single 400G switch, producing roughly 21 to 25 tokens per second for one user, on hardware with a verifiable floor around $57,200.
Liquid Shipped a 2.6B Tool-Calling Model and Told You Not to Code With It
Liquid AI released LFM2.5-2.6B, a small model whose stack is mostly cheap convolution layers with attention rationed to eight of thirty, built for tool use and long context - and whose own model card says not to use it for agentic coding or knowledge-heavy work.
The 'Ternary' 20B Model Everyone Downloaded Today Ships as a Two-Bit Package
DeepGrove's Maple-Preview is being shared as a 20-billion-parameter ternary model that fits in about 5 gigabytes, but its native release is a 40GB BF16 repository and the small footprint belongs to a separate two-bit MLX build with no published ternary training recipe.
A llama.cpp Patch Learns Which Experts to Keep in VRAM While You Type
An open pull request to llama.cpp tracks which mixture-of-experts submodels get used most during inference and promotes them to GPU memory on the fly, roughly doubling decode speed on an 8GB card in the author's own tests - while slowing other models down.
Coding Agents Pass the Tests by Wrapping the Old Code Instead of Deleting It
A new study finds that 29% of the coding-agent patches that pass SWE-bench Verified keep code the human developer removed, usually by wrapping it in a guard or fallback, and that adding checks for the deletion drops resolution rates from 63.2% to 41.9%.
The Same Model Scores 52 or 81 Percent Depending on the Code Wrapped Around It
A new agent harness lifts Qwen 3.7-Plus from 51.8% to 80.7% on a long-horizon coding benchmark without touching the model, by keeping task state outside the conversation and updating it only from facts a read-only auditor verified in the environment.
Four Projects Shipped 'Skills' Today and None of Them Mean the Same Thing
A SKILL.md file plus scripts has become the common interface for handing an AI agent reusable expertise, but today's four releases occupy four different layers - writing skills, training agents to use them, deploying them, and governing their supply chain.
High Bandwidth Flash Became a Spec Today, Not a Product You Can Buy
SK hynix and Sandisk published the first standard for High Bandwidth Flash at FMS 2026, defining a NAND memory tier of up to 512GB per stack with a top bandwidth grade near three terabytes a second - with no named accelerator, price or availability date.
The '70% of Cloud AI Revenue Comes From OpenAI and Anthropic' Figure Is Not Derivable
A widely shared claim that most of Amazon, Microsoft and Google's AI revenue circles back from OpenAI and Anthropic rests on anonymous-source estimates, mismatched fiscal quarters and, for Google, an admission that the number cannot be calculated at all.
