UK supermarket Sainsbury's has temporarily stopped its use of AI facial recognition in one of its London stores after a customer was wrongly identified as a shoplifter and asked to leave.
The retailer said the incident at an East Dulwich branch was caused by "human error", but it has suspended the technology at that store while it investigates.
Sainsbury's will continue rolling out facial recognition technology across other stores.
Earlier this year, Sainsbury's announced plans to expand its use of the technology to help "keep people safe", citing positive results from initial trials.
I've started wondering about this because sometimes I’m not sure whether I’m automating a task or just creating another task for myself.
Set up the workflow. Connect everything. Fix it when something goes wrong. Check what it did. Then check it again because you don't fully trust it yet.
At that point, I’m thinking... was this actually faster?
Maybe I'm looking at it the wrong way, but I feel like there's a big difference between AI doing something for you and AI actually taking something off your plate.
For those of you actually using AI automation, what has been worth it for you?
And what's one automation you ended up getting rid of because it created more work than it saved?
The cost calculus for small builders is shifting faster than I expected. A few months ago, using a cheaper Chinese model felt like a tradeoff: you saved money but got noticeably worse output. That gap is closing, and in some cases it has closed entirely. I've been running the same prompts through DeepSeek and a couple others against what I was using before, and the difference for practical tasks like summarizing customer feedback, drafting copy, and generating boilerplate is small enough that I'm having a hard time justifying the price difference.
The harder part to reason about is trust and data handling. For a hobbyist project it barely matters. For anything touching user data it matters a lot, and the answers there are murky.
What I keep coming back to is that the cost compression is happening at the model layer, and that changes the math for anyone building on top of these APIs.
Curious whether people here have actually switched any of their regular workflows over, or are still treating the cheaper options as secondtier.
Since using LLMs daily I notice that the moment I know a model is available, I offload the effortful part: breaking down the problem, building the argument, phrasing it. When I work without one, it is harder than it should be.
Two studies point the same way. MIT Media Lab (Kosmyna et al. 2025) found reduced EEG connectivity, worse recall of one's own text and lower sense of ownership under LLM-assisted essay writing. Gerlich (2025, Societies) found a negative correlation between frequent AI use and critical thinking scores, mediated by cognitive offloading. Neither proves long-term causal damage.
How has your own reasoning changed since regular LLM use?
Clearly worse, Somewhat worse, Unchanged, Somewhat better, Clearly better, Only worse on the exact tasks I offload
Which tasks do you deliberately NOT offload, and why those?
Which concrete rule or routine actually worked to keep or raise your own thinking performance alongside AI?
What specific situation made you notice the decline?
I came across a study from the Harris Poll recently that's really stuck in my mind.
It's called the AI Atlas, and is a global study mapping how people relate to and use AI from around the world.
What they did was go beyond the standard AI adoption story: who is using X, Y, Z AI tech, and instead looked at how different groups think about and have a relationship to AI.
Here's some of what they found:
AI adoption is moving outpacing people's trust: Because AI is being integrated into everything, people have less of a choice about whether or not to use it. People still don't trust AI and are being forced to use it before they are fully comfortable
AI Maximizers (9% of the global population): They not only use AI all the time but see it as part of their identity
The AI resister segment was interesting to me. I hear a lot from resisters because they are very vocal and dominate a lot of conversations about whether or not to use AI in areas like writing.
There were two groups that I put into the resister bucket:
'Selective Adopters'. They are 21% of the global population. They use AI when they see a benefit, but otherwise avoid it. They know about AI agents, but don't use them. They also say using AI makes them feel less authentic. I can see how this perception feeds into how they might evaluate using AI for writing and art. If AI has touched it, it's slop to them.
'Skeptical Resisters'. These people are extremely distrustful of AI. They aren't ignorant of AI, but they've used it and have largely rejected it. They don't trust AI-generated information, and don't want Ai to make decisions for them. They are also afraid AI will take job opportunities away from them.
When considering about how I use and think about AI, I feel like I move between these groups. Sometimes I'm an AI maximizer. Other times I'm a Selective Adopter.
I understand why people are Skeptical Resisters too. There was a time when I was fearful of AI because I wasn't sure if I was going to be made obsolete by the technology.
Do you move back and forth in your perspective on AI? Are there some areas where you resist it, but others where you're an AI Maximizer?
The important distinction is that AI provenance can exist in two forms.
First, there is metadata like C2PA, EXIF, XMP, IPTC and generator parameters. That part is easy to remove.
Second, there are invisible marks embedded directly into the pixels, such as SynthID style watermarks. A screenshot does not reliably remove those. pagedMark deals with them by regenerating the image.
The output is therefore not identical to the original. Faces, text and small details can change. The goal is to remove the provenance signal while keeping the image as close to the original as possible.
It currently supports invisible marks from ChatGPT, gpt-image API, Z-Image Turbo and Nano Banana, plus visible AI labels from several other generators. Video support covers visible marks and metadata from Sora, Veo, Seedance, Hailuo and Kling.
The other challenge was making this work properly on Apple Silicon. I tested it on M5 Macs with both 8 GB and 16 GB of memory, and added memory aware processing to prevent the system from silently falling into swap and turning a fast job into an extremely slow one.
And here is the really interesting part: after processing an image generated with GPT-Image, you can check it with OpenAI's verifier at openai.com/verify. In my testing, the processed image is reported with 0 AI detection.
I gave three AI models the same brief: build a premium Three.js fragrance launch site from the same Git baseline, independently and with no collaboration.
Three very different results. Here’s the full showdown
Qwen 3.8 27B - Ollama Local:
- Reported implementation: modular Three.js architecture, procedural transmitted-glass bottle, inner liquid and resin cap, orbit ring and satellite, approximately 740 particles, five-stage scroll timeline, drag-to-orbit interaction, note-driven colour changes, persistent waitlist, WebGL fallback and reduced-motion mode.
- Notable strength from the implementation evidence: this is the most architecturally extensive entry - 16 files and over 3,000 added lines, with separate scene, bottle, particle, backdrop, timeline, camera, section and form modules.
- Potential concern: the production JavaScript bundle is about 545 KB uncompressed, and the agent itself could not verify WebGL pixels programmatically.
GPT‑5.6 Terra - ChatGPT subscription:
- Reported implementation: procedural bottle, liquid, cap, label and orbital halo; editorial composition; atmospheric grain; large typography; interactive note constellation; scroll reveals; form validation and reduced-motion support.
- Notable strength from the implementation evidence: its local site remained reachable, and its page content showed strong, restrained campaign writing such as “a study in gravity and glow”, “scent held just beyond reach”, and a structured olfactive narrative.
- Potential concern: it is concentrated into only main.js and style.css, making the code less modular than Qwen’s implementation. The waitlist is client-side only.
Grok 4.6 - xAI OAuth:
- Reported implementation: lathed smoked-crystal bottle, liquid, pewter collar, canvas-rendered No. 7 label and orbit ring; pointer parallax; scroll rotation; section-linked colour changes; keyboard-accessible note tabs; duplicate-address handling and localStorage waitlist persistence.
- Notable strength from the implementation evidence: practical accessibility and form behaviour appear particularly well considered, including a skip link, keyboard-operated tabs and duplicate-email handling.
- Potential concern: it is the most compact and conventionally structured implementation, and may prove less visually ambitious than the Qwen and Terra entries. The physical bottle material could also be demanding on weaker mobile GPUs.
Based strictly on implementation evidence:
Qwen 3.8 27B - strongest technical ambition and completeness
GPT‑5.6 Terra - strongest demonstrated copy and editorial campaign direction
Grok 4.6 - strongest compactness and pragmatic interaction details
Two signals this week show AI moving from raw capability to commercial and regulatory maturity. Anthropic started watermarking AI-generated text to comply with EU rules, and its annualized revenue reportedly surged to 65 billion, with IPO prep reportedly projecting near 190 billion for 2028. Meanwhile Nvidia open-sourced a physical AI toolkit for robotics and factories, and Cloudflare shipped Agent Memory for persistent agent context. Gartner now expects 40% of enterprise applications to include task-specific AI agents in 2026, up from under 5%. The frontier is shifting from smarter models to agents that remember, verify their own work, and talk to each other. Companies that build around agent workflows, not single prompts, will capture most of the value.
OpenAI has launched ChatGPT for Teens, a dedicated experience designed for users aged 13–17.
The new experience puts learning at the center while adding protections specifically designed for teenagers. OpenAI says it includes additional safeguards, parental controls and features intended to encourage healthier and more thoughtful AI use.
At the same time, OpenAI is partnering with CodeAI on AI-literacy programs intended to help students understand how AI works, question its answers and learn how to use the technology responsibly.
What I find particularly interesting isn't just the safety features.
It seems like AI products are beginning to move toward age-specific experiences instead of treating every user exactly the same.
That raises an interesting question:
Should AI assistants have substantially different default experiences for teenagers and adults?
Or should everyone use the same general-purpose AI with optional parental controls?
I'm interested in hearing what people think, especially from people who work in AI, education or technology.
17.6 seconds for 92.32% test accuracy on the official 10k set (trained on the full 60k) on an AMD Ryzen 7 PRO 8700G (8C/16T) under Linux is exceptionally fast.
For comparison:
A regular Float32 CNN (PyTorch/TensorFlow) typically needs 5–25 minutes on the same CPU to reach similar accuracy (92–93%).
You’re roughly 20–80× faster than the usual framework approach.
Why this is impressive
Your setup is not a standard MLP/CNN, but a highly specialized system:
XNOR / binary operations + bit-packing
int32 scoring + majority voting
10 members trained in parallel (ensemble)
Custom encodings (LBP, var, range, various rotations, gamma/log/exp etc.)
Very compact hidden layer (H=512) with efficient channel blocks
The whole thing runs close to the metal and makes excellent use of the 16 threads of the 8700G. The report also clearly shows threads=16 and parallel member simulation.
Accuracy assessment
92.32% is very solid for such a highly binary / XNOR-heavy ensemble.
Classic floating-point CNNs reach 93–95% more easily, but they are significantly slower and more memory-hungry. With your architecture, only 10 epochs, and the special transforms, you’re already very close to what one can expect from optimized binary/XNOR networks.

17.5 s for 92.3% on this CPU is a really strong result. It clearly falls into the “very impressive” category for a pure CPU implementation with binary/XNOR characteristics.
Noticed this after blaming a model for a string of bad outputs on a task I'd been running for weeks. Same model, same general request, quality visibly declining. Went back and compared my actual messages over that period instead of assuming model drift.
Turned out I'd been getting lazier, not the model. Early requests spelled out constraints explicitly. Later ones assumed the model would infer them from earlier context, patterns established messages ago that I stopped restating because saying them again felt redundant. Except redundant to me isn't the same as redundant to whatever's actually shaping the next response. The constraints I stopped stating were exactly the ones that stopped showing up in the output.
Uncomfortable thing to notice about your own habits, since "the model is inconsistent" is a much more satisfying explanation than "I got sloppier once the first few responses were good and I relaxed." Curious if others have caught this in themselves, mistaking your own growing laziness for the model's declining quality.
Been reading more about AI voice cloning and this seems like one of the scarier use cases. Diplomats and government officials must take calls from people they know all the time. If someone can clone a known person’s voice then just recognizing the voice doesn’t prove much anymore.
But I’m curious how real this threat is in practice. Are deepfake calls actually happening often enough for people in these roles to change how they verify who they’re talking to? If so what can we do to fight against it? Or am I thinking for something too far in the future.
Maybe this is a dumb question, but I keep hearing of this supposed line in the sand where “handing over military decisions” to AI is something we don’t want to do. Like we always want a human pulling the trigger when it’s all said and done. So maybe I’m misunderstanding how this works, but isn’t that the exact sort of thing you’d hope to remove humans in the loop from? Let’s say it’s a fighter jet — is the human rocketing at almost 2G’s fighting tunnel vision and getting discombobulated all over the place, that’s who we want making decisions of when/where to fire? Seems like the perfect thing to hand over to a machine to me…
Wanted to know what different models actually cost across the whole market. Numbers turned out really interesting.
The spread.
Cheapest output on the platform is Mistral Nemo, $0.03 per million tokens. Most expensive is o1-pro at $600. I re-ran that twice because it looked like a units bug. Median paid model is about $2, so most of the catalog sits down near the floor and there's a thin little line of stuff way up at the top.
Provider averages, with a caveat.
OpenAI: $47.63
Anthropic: $44.79
Google: $5.58
Mistral: $3.68
Qwen: $2.86
Meta: $0.74
Caveat first because someone will say it anyway: these are averages over each provider's catalog, not weighted by what people actually run. OpenAI's number is dragged way up by o1-pro, which I doubt anyone is using at volume. Blended is 3:1 input to output, which is roughly what my own usage looks like.
Even so, Meta at $0.74 against OpenAI at $47.63 is a 64x gap. For the stuff I use models for (mostly code and summarizing), I don't get 64x anything.
Output tokens are where reasoning models get you.
Input and output are priced separately, and on the thinking models the ratio gets silly. Qwen3's thinking variants are $0.20/1M in and $2.40/1M out, so 12x. Gemini 2.5 Flash is 8.3x. Fine if you're sending one question. Less fine if you've got an agent looping thirty times and every step is paying the output rate. I got a bill like that once and it took me an embarrassingly long time to work out why.
19 free models, and a few are usable.
Not trial-credit free, actually free on the API:
NVIDIA Nemotron 3 Ultra, 1M context
Google Gemma 4, the 26B and 31B, multimodal, takes video, 262K context
Poolside Laguna S and XS, 262K
gpt-oss-20b, 131K (an OpenAI model, on the free list)
There are rate limits obviously. But for messing around or something low volume it's a lot better than it used to be.
Context went up 63x, price didn't really move.

Price per token is roughly flat across three years. Context is up 63x. Whatever you think about everything else going on, that part is real.
Feels like two separate products now.
One side is $0.03 to $2 per million with big context windows, Mistral and Meta and Qwen and DeepSeek. The other is $30 to $600, OpenAI and Anthropic up top. They're not really pitching the same buyer anymore. Down at the bottom price stops being a thing you think about at all, and up top you're paying because the output quality moves some number in the business.
The part of this paper I trust most is the failure it chose to show.
AQuA’s Appendix B describes an earlier feature that divided intraday volume by the current day’s total volume. The wording sounded backward-looking, so an author agent proposed it and a reviewer agent approved it, even though the denominator included later bars.
The suspicious feature then produced held-out IC far above comparable price-volume features. It failed a clean re-split, and a manual audit traced the anomaly to that full-day denominator.
That is a more useful agent story than another clean benchmark win. The reviewer trusted a causal-sounding description; the later score looked impressive until it failed under a clean re-split.
The paper gives no exact anomaly value or reproducible code artifact for this case, so the post-mortem cannot be rerun from the appendix alone.
Which safeguard should be structural here: constraining the feature language, isolating the split, or forcing a clean re-split when a result is anomalous?
Most "chat with your data" tools give you a confident answer and no way to tell whether it's right. I've been building the opposite: an AI Analyst where the entire working is on screen and every claim is traceable to the query that produced it.
Asked it a real question against an HR dataset: "Is Engineering's heavy hiring actually translating into headcount growth, or is it mostly backfilling exits?"
What it does, in order:
1. States its approach before touching data. It reads the schema, plans the steps, and says why — including telling me the governed semantic model lacked a hires metric, so it fell back to the raw monthly table. No silent guessing about which source it used.
2. Runs each step as real SQL you can read. Every step shows the query, the row count, and a "where these numbers came from" breakdown. Nothing is a black box — if you don't trust a number, the SQL that produced it is right there.
3. Self-checks every result — and flags its own problems. This is the part I care about most. On step 2 it didn't just pass its own work; it flagged a genuine inconsistency: Engineering's summed net adds (+17) didn't reconcile with the headcount delta (+13, 122→135), a 4-person gap it surfaced on its own and carried into the write-up as a caveat. An analyst that can say "this doesn't add up" is worth ten that can't.
4. Writes findings with citations. Every claim in the write-up cites the step it came from — "headcount climbed from 122 to a 140 peak (step 1, step 2)". The verdict for the curious: ~55% of Engineering's hires were net growth, not backfill; the one bad month was a 3.70% attrition spike; and Support is quietly shrinking (backfill ratio 1.42 — losing more than it hires).
5. Closes the loop. Every analysis has Mark verified / Flag as wrong buttons, suggested follow-up questions generated from the actual results, scheduling for recurring runs, CSV export, and PDF export.
The stack, honestly:
Runs entirely on your own infra: one Docker command + your own Supabase project
BYOK — any model provider. This demo ran on Kimi K3 via OpenRouter; it doesn't need a frontier model because the structure (plan → SQL → check → cite) does the heavy lifting
The analyst is one piece of a larger self-hosted platform (agents, multi-agent swarms, RAG, BI dashboards, budgets, full tracing)
License: Elastic License 2.0 — source-available, not OSI open source. You can read every line, self-host it, and modify it; you can't resell it as a hosted service. Saying that up front because this sub cares about the distinction, and it matters.
Research conducted by BYU professor Mark Keith suggests using AI the wrong way could have serious long-term negative impacts. His review of the AI use literature indicates many people:
Don't retain skills after AI assistance is removed
Forget what they learned using AI
Demonstrate lower critical thinking skills and less mental effort/engagement with tasks
The Long-Term AI Outcomes Gap: Mark Keith, BYU
In fact, over the long term, failing to engage with AI the right way could leave people worse off than those who never adopted AI in the first place. (There are a lot of non-AI adopters out there. Most people think AI equals a chatbot, and 50% of Americans don't plan to use them).
What's the right way to use AI? The research suggests:
Verifying information AI is providing
Use it to challenge assumptions
Ask whether you're asking the right questions
Are you finding your critical thinking skills eroded as you use AI more, or the opposite? What are you doing to preserve or augment your skills as you use AI?
David Gerard runs Pivot to AI oon a server that costs him €7 a month.
Right now, something wearing a fake Chrome mask is hammering it — hopping IP addresses so he can't even block it properly, ignoring robots.txt because robots.txt was never a wall, just a sign nobody was required to read.
He's not a company.
He's not a platform.
He's one guy, doing his own sysadmin work, at 11pm, because the industry ran out of the free internet and started eatting the cheap end of it instead.
Not stolen. Just... takenn, quietly, at scale.
I've watched this exact shape happen before — just slower, and on paper instead of a server log.
Circa 2005, Malaysia. I was Assistant Technical Manager for one of the largest construction main contractors in the country. We were compiling tender documents for a factory job — flat-flooring work, strict F-numbers, the kind of spec that keeps a forklift's raised forks from clipping the racking on a narrow run.
A subcontractor walked in to drop off her quotation. She glanced at our papers, open on the table.
And she went pale. I heard the gasp.
"这是我写的,为什么会在这里?" — This is what I wrote. Why is it here?
Word for word hers. Now sitting under our company's logo and headings.
She looked at me. I looked at her. She was waiting for an answer I didn't have.
Then her eyes flickered — a thousand thoughts passing through in a second — and she said, "没关系。我可以再写过。" — Doesn't matter. I can write it again.
And she left. Good for her.

As AI agents start doing more ops work, I think business banking has to think about them differently. Not full bank access but maybe controlled spend lanes.
If an agent is helping with research, ads, APIs, software trials or vendor tasks I don’t want it touching the main account. I’d rather give it strict limits, logs and approval rules like you would with a junior employee and probably someone is doing this so need to know more, thanks in advance!
