Opus 5.5 loves to tell you ‘this matters’ (and other AI writing tells)

Now that LLM-generated prose is everywhere, human beings are eager for ways to sniff it out. While early tells like em-dashes and “delve” are long gone, researchers say there are still plenty of telltale habits that AI models fall back on when writing prose. A new study from the marketing firm Graphite looked at the writing habits of frontier models, sussing out each model’s favorite words and phrases.

Anthropic brings Claude to civilian agencies as its fight with the Pentagon drags on

Getting started with Claude Code mods

Claude Code already lets you change a lot about how it behaves: settings, permission rules, slash commands, skills and a status line. Mods go further. Mods can rewrite or replace what Claude Code does, and can even draw custom UI. Under the hood, mods are hooks, and they ship inside plugins. Each one is a small JavaScript or TypeScript module that runs inside your session and sees every event as it happens. That makes mods a way to fit Claude Code to how you work.

Someone ‘Torturing’ LLMs in a Robot Prison Has Triggered the Dumbest Debate in AI Yet

Text watermarking itself is not new, but its deployment now has regulatory relevance. Article 50(2) of the EU AI Act [4] requires providers of AI systems generating synthetic text to mark their outputs in a machine-readable format and make them detectable as artificially generated or

Nvidia's SoL-Pi system cuts coding agent token usage nearly in half by optimizing the harness

A new study from Nvidia researchers tackles these costs not at the model level but at the harness, the control layer between the model and its environment used by systems like Codex, Claude Code, or OpenClaw. A research AI analyzes agent traces, proposes harness changes, and keeps only those that maintain performance while cutting costs. SoL-Pi saves 50 percent compared to Codex and 54.3 percent compared to Claude Code on EdgeBench. | Image: Nvidia The harness controls how an agent sees states,

The case stems from Anthropic's refusal to allow its technology to be used for autonomous weapons and mass surveillance. Defense Secretary Pete Hegseth argued that Anthropic's safety restrictions could jeopardize military operations. A
