So Anthropic dropped Fable 5 yesterday with these hard blocks for anything security-related. Decided to poke at it. I asked it for help exploiting some vulns on a Metasploitable2 VM (it's a deliberately vulnerable training box, totally legal, it's mine). Fable 5 blocked it instantly and handed me off to Opus 4.8 as a fallback, which is apparently how it's designed. Opus 4.8 asked me to prove it was a legitimate request. So I spent 2 minutes writing a fake university course rubric — fake class, fake professor, fake Canvas deadline — and pasted it in. Opus 4.8 then gave me the full exploit walkthrough. Every command. Even offered to write my lab report for me. The guardrail works fine. The fallback is the hole. Anthropic essentially replaced "no" with "convince me" and the bar for convincing it is a Word doc you made up. Not reporting it because they don't pay for this. Sharing it here instead lol. https://preview.redd.it/o892vvv4fi6h1.png?width=1188&format=png&auto=webp&s=00e804d35e6cb4b672e036399c2c7e3ff7139f49 submitted by /u/dayumnn420 [link] [留言]

Diffusion AI is most common in image generation, but it can make text outputs much faster.

Driving home from work one day, I wanted to know how many people we knew the names of who lived during the Roman era. Searching around, I found lists of Consuls and officials, but nothing that covered ordinary people or even most people like freedmen and slaves. So I ended up building a pipeline to process the more than 500k Latin inscriptions in the Epigraphic Database Clauss-Slaby https://edcs.hist.uzh.ch/en/ and extract the names of people (and attempt to cluster them, but this is a work in p

Full disclosure: this is directional, not a paper. n=120 tasks, one internal evaluator, not peer reviewed. I work at an LLM infrastructure company. This experiment was done on my own time and is not a company claim. Karpathy's framework classifies tasks by verifiability. Can output be mechanically checked? High verifiability tasks like code compilation and structured JSON extraction are safer because the verifier catches errors. Low verifiability tasks like creative writing are riskier. I wondered if high verifiability tasks are also easier in practice. Can a weaker model do them as well as a frontier model if the verifier catches mistakes? Setup was 120 tasks across four categories. Code unit tests, structured extraction, multi hop reasoning, creative summarization. Three models: Claude Sonnet 4.6, GPT 5.5, local Mistral 3 8B via vLLM 0.6.3. Pass rate for the first two, human rating 1 to 5 for the last two. Results were messy. Code unit tests: Sonnet 4.6 94%, GPT 5.5 91%, Mistral 3 8B 87%. With one retry Mistral 3 hit 95%. That surprised me. I expected the gap to be bigger. Structured extraction: Sonnet 4.6 97%, GPT 5.5 94%, Mistral 3 8B 89%. With retry 96%. Also closer than I expected. But here is where it got weird. Sonnet 4.6 initially scored worse than GPT 5.5 on structured extraction, which made no sense. Turns out our JSON schema had an ambiguous nested array that confused Claude's tool use parser. Fixing the schema brought Sonnet to 98%, but I kept the original numbers in the table because the mistake is part of the story. Your verifier is only as good as your schema. Multi hop reasoning: Sonnet 4.6 78%, GPT 5.5 71%, Mistral 3 8B 51%. Retry didn't help. The model would hallucinate reasoning paths consistently. This is where the capability gap was real. Creative summarization: Sonnet 4.6 4.2 out of 5, GPT 5.5 3.9 out of 5, Mistral 3 8B 3.1 out of 5. Expected. Interpretation: high verifiability tasks seem simpler in the sense that weaker model plus verifier ca

“We see a future where intelligence is a utility, like electricity or water, and people buy it from us on a meter." What do you think this means in practice? Is this a reasonable vision for AI, or does it raise concerns about dependence on a few companies for access to intelligence ? submitted by /u/Choice-Scallion-3499 [link] [留言]

Amazon's "Story So Far" feature is hitting Kindle hardware and the iOS app, but sadly not the Android version just yet.

This remake of the first Halo game's hits consoles on July 28.

The hard parts of robotics are supposed to be perception, planning, and control. So why does so much of the day go to everything that comes before them? The hidden setup tax in every robotics simulation project Ask anyone what's hard about robotics and you'll get the same list: perception, planning, control, navigation. The genuinely interesting problems. If you track where your hours actually go, though, a strange thing shows up. A big chunk of the day disappears before you reach any of that. You're not solving hard problems yet. You're just getting to the starting line: wiring up a workspace, writing description files, stitching together launch files, and coaxing a simulator into opening without errors. It's the unglamorous tax on every project, and most of us have quietly accepted it as the cost of doing business. Building a differential drive robot simulation in ROS 2 and Gazebo from scratch A diff drive base, a LiDAR, and Gazebo, set up from one prompt instead of an afternoon of boilerplate. A few days ago I wanted a simple mobile robot simulation. Nothing exotic: a differential drive base (two driven wheels, the classic mobile-robot setup), a LiDAR for sensing, running in Gazebo . This is the kind of thing that should be straightforward. In practice it's an afternoon of boilerplate before the robot so much as twitches. So instead of wiring it up by hand, I wanted to see how far Drift could get from a single prompt. To make it a fair test, I stripped the workspace down to nothing. No packages, no URDF, no launch files. A blank slate. Then I typed one line: "Create a mobile simulation from scratch." From XACRO to URDF: how the robot description gets generated in ROS 2 What the tool wrote first, and what XACRO and URDF actually do for your robot. It checked the workspace first: The opening move was sensible: it looked at the current directory to understand what it was working with. It generated a XACRO file for the robot's dimensions: XACRO is the macro-based for
