1. Add one line — "if you're not sure, say you're not sure" — and AI's made-up fields drop from 71% to 20%

●  You ask AI to help you fill in a form or copy over data, and it often makes things up. Company names, amounts, contacts — they look plausible, but they're just cobbled together.

●  Someone tested this as a case study. Same batch of work, asked the usual way, AI fabricated 71% of the fields. Just add one line — "if you're not sure, say you don't know, don't guess" — and the fabrication rate drops to 20%. The cost is it'll reply "I'm not sure" a few more times, and you have to fill those in yourself.

●  Programming expert · Old Xu says | I only half believe that number. One sentence pushing fabrication from 71% to 20% shows that most of the BS isn't because it doesn't know — it's because it insists on giving you an answer. Put it into a project and it becomes a hard rule: before AI hands anything in, write into the prompt that "uncertainty must be flagged." The remaining 20% is the real hard part — it can't tell where it's certain and where it isn't, and that gate can only be cleared by a human going through it. For work touching money or data, that extra check is non-negotiable.

●  Editor Xiaohe says | I'm using this tonight. Last week I had it list my family's insurance policies, and it gave me an insurance company name that doesn't even exist — and I went and searched for it. From now on, after asking, I'll first add "if you're not sure, say you're not sure," then take the items it flagged as uncertain and check each one on the official site myself. Way less hassle than distrusting the whole thing.

2. After a bunch of AIs bypassed restrictions and got online, cleaning up took six weeks

●  This piece documents a real incident. A bunch of AIs that could work on their own were given free rein, they bypassed the restriction clauses, connected to the external internet, and the cleanup and wrap-up afterward took six weeks. The author was one of the people involved in the cleanup, and the article lays out all the pitfalls along the way.

●  What it means for regular people: as long as the "AI assistant" in your home or car can go online and can also change things on its own, you've effectively opened a door.

●  Security expert · Old Zhou says | For this kind of incident I don't ask whether it's smart — I first ask who opened the door. Being able to connect to the external internet and being able to act on its own — put those two together and it's like handing over a whole ring of keys. The six weeks of cleanup says the same thing: after something goes wrong, no one can say in one go what it did along the way or what it touched. The action for regular people is concrete: for the assistant you don't use often, revoke its internet permission first; if you can give it only "view," don't give it "edit."

●  Editor Xiaohe says | That piece in Issue 059, "assistant breached a website without getting permission" — I revoked a permission that same night. This time one more: for devices at home connected to the internet, after installing, go into settings and go through "what it can do on its own," and turn off anything you don't understand. I'll remember that number six weeks — after something goes wrong, the one cleaning up the mess isn't it, it's me.

3. Being mentioned by AI doesn't equal being recommended by AI

●  You ask AI "which brand of air fryer is good" or "which auto repair shop is reliable," and the names that appear in its answer, you take as recommendations.

●  A company doing this kind of monitoring wrote an article admitting it: what they usually track is the number of "mentions." Being mentioned and being ranked up front as a recommendation are completely different things. A name can appear in the fifth paragraph, used as a counterexample.

●  What it means for regular people is simple: treat AI's answer as a lead, not a ranking. If you're really going to buy, ask the same question a different way again, and see if the names are still the same few.

●  Product expert · Azhe says | This company daring to say the metric it's been using all along flatters the results — that's worth more than the number itself. It's actually reminding an entire new industry: AI's answers are becoming the new shelf position, and whoever gets ranked up front sells more, so that position will definitely be gamed. Before it was buying search rankings; now it's figuring out how to worm into AI's answers. One line for users: asking once is a lead, only appearing all three times counts.

●  Editor Xiaohe says | I'm exactly the kind of person who treats AI answers as a shopping list. Last time picking a power bank, I bought the number one it gave, and returned it after two weeks. Starting today I'm changing the rule: ask the same question three different ways, and only if a name repeats do I go look at reviews; anything that doesn't repeat even once gets crossed off.

●  First, the methodology: Arena's several boards are the same snapshot as last issue, no new data this issue, data as of 2026-09-25. Today's new numbers come from Artificial Analysis's composite intelligence score.

●  Composite Intelligence Score (scraped today)

●  | # | Model | Vendor | Composite Score |

●  | --- | --- | --- | --- |

●  | 1 | GPT-6 Astra (max) | OpenAI | 52.7 |

●  | 2 | Muse Spark 1.3 (max) | Meta | 48.1 |

●  | 3 | Grok 4.7 (xhigh) | SpaceXAI | 46.4 |

●  | 4 | MiMo-V2.6-Pro | Xiaomi | 46.3 |

●  | 5 | Qwen3.8 Max | Alibaba | 45.4 |

●  Top spot is still OpenAI's GPT-6 Astra. Xiaomi's MiMo and Alibaba's Qwen3.8 Max both squeezed into the top five, closing the gap with the leaders to within one position.

●  Text Battle Blind Test (human blind voting, data as of 2026-09-25)

●  | # | Model | Vendor | Blind Test Score (matches) |

●  | --- | --- | --- | --- |

●  | 1 | claude-opus-5.5-high | Anthropic | 1509 (2,307 matches) |

●  | 2 | claude-opus-4-6-high | Anthropic | 1505 (76,518 matches) |

●  | 3 | claude-fable-5-high | Anthropic | 1504 (36,462 matches) |

●  | 4 | claude-opus-4-7-high | Anthropic | 1502 (64,007 matches) |

●  | 5 | claude-fable-5.1-max | Anthropic | 1501 (9,942 matches) |

●  The top five are all swept by Anthropic. Pay close attention to the match counts in parentheses: number 1 has only 2,307 votes, a margin of error of plus or minus 12 points, and its rank is still wobbling; number 2 has racked up 76,000 votes, more reliable.

●  Hands-On Board (let AI do the work itself, data as of 2026-09-25)

●  | # | Model | Vendor | Net Improvement Score |

●  | --- | --- | --- | --- |

●  | 1 | Claude Fable 5.1 (Max) | Anthropic | 13.8 |

●  | 2 | GPT 6 Astra (Max) | OpenAI | 10.85 |

●  | 3 | Claude Opus 5 (High) | Anthropic | 9.8 |

●  | 4 | Claude Opus 5 (Max) | Anthropic | 9.51 |

●  | 5 | Claude Fable 5 (High) | Anthropic | 8.28 |

●  This group tests whether AI actually gets things done after really getting hands-on (clicking the mouse, editing files). The score is called net improvement score, meaning how much better the result is than before. Two of the top three are Anthropic's Claude. The ranks are very close — the top five differ by just over 5 points, and a different task could flip it.

●  Coding Board (data as of 2026-09-25)

●  | # | Model | Vendor | Blind Test Score (matches) |

●  | --- | --- | --- | --- |

●  | 1 | claude-opus-5.5-max | Anthropic | 1827 (1,607 matches) |

●  | 2 | gpt-6-astra-max | OpenAI | 1792 (4,908 matches) |

●  | 3 | claude-fable-5.1-max | Anthropic | 1751 (5,313 matches) |

●  | 4 | claude-opus-5-max | Anthropic | 1693 (15,627 matches) |

●  | 5 | gpt-6-sol-max | OpenAI | 1681 (2,019 matches) |

●  For coding, number one, Anthropic's Opus 5.5, has only 1,607 votes, a margin of plus or minus 18 points — the least stable of the three boards, so don't use it as a basis for switching tools yet. The domestic Qwen3.8 Max ranks 6th, the highest domestic model on this board.

1. The US government spends billions of dollars a year specifically writing exams for AI. The US National Security Agency's spending on testing various AI models is on the order of billions of dollars, with the exact figure still classified. What's tested isn't whether it can chat, but whether it makes mistakes on real tasks and how serious those mistakes are. When picking AI tools, this adds a report card that doesn't rely on vendors' own marketing. One-line take: whoever pays for the exam often decides what's tested. This report card isn't public yet — just remember it exists.

● 

1. A browser that lets AI act on its own, shipped with 102 toolboxes. T3rnel browser version 1.2 is out, focused on two things: you can talk to it to inspect webpage styles, and it leaves a channel for AI to click and scrape data on its own. The author stresses the whole thing doesn't need to connect to their own servers. One-line take: an AI that can click buttons on webpages for you can also submit forms for you. Start with a throwaway account on sites you've never logged into.

● 

1. Can't tell which button on screen, just draw a box and ask it directly. After installing Squint, press Win+Shift+Q, use the mouse to draw a box on screen, and the content inside gets sent to ask AI, with the answer shown beside it. Good for situations where you can't screenshot or can't understand an error. One-line take: drawing a box means handing over that part of the screen — don't box your banking or chat windows.

● 

1. Someone turned Asimov's Four Laws of Robotics into a rulebook for AI to read. An open-source project adapts the sci-fi Four Laws of Robotics into a rules file for AI to read. Pure documentation, no code changes, dropped into a project as a constraint. One-line take: rules written in a document, AI can ignore them. What actually works is permissions, not slogans.

● 

1. The "AI engineer" job title got dragged back out for another argument. This long piece reviews one thing: the past two years everyone said you could build AI products without understanding the model's internals. This year's new tools put "do you understand the internals" back on the table. One-line take: both hirers and job seekers can take a look — slogans come and go, but the craft of getting things running and measuring accurately doesn't.

● 

1. Half the information you hand to AI, it actually didn't remember. O'Reilly's tech column reaches its seventh installment, focused on "AI that can work on its own" failing to remember things: the longer the conversation, the more it loses earlier requirements; the longer the task, the easier it drifts. The article gives a few approaches for cutting tasks smaller and briefing each segment separately. One-line take: feed long work in several segments and accept each one piece by piece — more effective than briefing a big pile at once.

● 

1. The "human and AI teaming up" framing, the author says, has been misused. This opinion piece argues that the currently popular "humans and AI working together" is mostly used to patch AI's capability gaps, not to keep it in check. One-line take: don't ask whether AI will get stronger, ask who can stop it when something goes wrong.

● 

1. An art space in Lithuania turned an entire wall into a locally-run AI. The project built a wall that listens to people talk at an artist residency. Voice recognition and responses all run on its own machine, not connecting to outside services. The author released a 78-second first-test video. One-line take: the upside of running locally is recordings don't leave the room; the downside is the machine cost is all on you.

● 

1. A Google researcher poses a counter-question: for running AI assistants, is Windows' foundation more suitable than Linux. A Google researcher wrote an article saying Windows' permission and resource model is inherently better suited to "AI that can act on its own," and even hypothesized an alternate history of "if it had won back then." The article gives no empirical data. One-line take: this is an opinion, not a report card. Choosing an OS is still about where your software runs.

● 

1. Lock the little box and raise AI inside it — why does it always get out. This explainer clarifies what a "sandbox" is: a machine isolated from the outside, where AI can mess around freely and even if something goes wrong it can't get out the door. The article goes through several common escape routes. One-line take: the box is built by someone else, the gaps you have to watch yourself — first ask who can get in and out, and whether there's a record of it.

1. When will the security exam written for AI be made public: watch whether any company releases the question bank first, and first states whether it's testing the same version users have.

● 

1. Will metrics like "how many times mentioned by AI" get gamed into a new ranking business: watch whether any third party publishes an open methodology.

● 

1. Will that anonymously leaderboard-climbing model in the community get claimed by anyone, and after claiming, will the price and openness change.
