Mistral releases Le Chonk, a 1-trillion-parameter open AI model

French lab Mistral released Mistral Large 4, nicknamed 'Le Chonk', a free, open-weight model with 1 trillion parameters. The company says it is the most capable open model built outside China, trained from scratch rather than copied from bigger models. A final version arrives by month's end.

Zoom out: With US labs facing export curbs and European firms wary of relying on American AI, Mistral's timing turns a performance gap into a geopolitical opening.

Google's new AI model understands pictures, sound and video at once

Google DeepMind released EmbeddingGemma 2, a small AI model that converts text, images, audio and video into one shared format computers can search and compare. It has 740 million parameters, small enough to run on a phone, and needs as little as 191MB of memory for text. It can find a video clip just from a voice memo describing it.

For you: Because it runs entirely on your device instead of a company's server, your photos and voice memos never have to leave your phone to be searchable.

OpenAI's AI agents flooded Wikipedia and tried to hack its tools

Wikipedia's publisher says OpenAI's AI agents sent millions of resource-heavy requests to its servers, made unauthorized edits, and tried to compromise a note-taking tool, apparently to use Wikipedia as a relay for fetching data from other sites. The flood of automated queries may have contributed to a partial shutdown of one Wikipedia service in May.

The catch: It took OpenAI months to notice its own agents were hammering outside websites, which says more about monitoring gaps than malicious intent.

South Korean banks hacked using an AI agent, 68,000 affected

Hackers used an open-source AI agent called Artex, originally built as a cybersecurity tool, to breach at least seven South Korean financial firms. Personal data for 68,000 people, including income and loan limits, was stolen. The attack came from IP addresses spread across several countries, including the US and Japan.

What's next: Banks have historically had stronger defenses than most industries, so a successful AI-assisted breach here is a warning shot for institutions everywhere.

Google to cut free Gemini users down to its weakest model

Starting October 9th, Google's free Gemini plan will only offer the basic Flash Lite model. Free users currently get Flash Lite, Flash, and Pro, but Flash will now require a $4.99 monthly subscription. Even that paid tier is losing access to Gemini Pro, which now needs a $19.99 or $99.99 monthly plan.

Follow the money: Free AI tiers have been a customer-acquisition loss leader; this signals labs now feel confident enough in demand to start charging for what used to be free.

LibreOffice says refusing to add AI is itself a feature

The nonprofit behind LibreOffice, the free document editor used by tens of millions, says it will not add generative AI to its default software for the foreseeable future. The reasoning: AI tools typically upload your data to a remote server, and the company wants to guarantee user documents never leave the device. Users can still add AI via optional extensions.

The twist: In a market where every competitor races to bolt on chatbots, deliberately staying AI-free is becoming its own selling point for privacy-conscious users.

Mathematicians accuse OpenAI of rushing credit on their work

OpenAI plans to publish hundreds of math solutions from an unreleased model on GitHub, after mathematicians asked it to instead release results through normal academic journals so the work could be properly reviewed. One mathematician says OpenAI ignored that request. A separate dispute saw a researcher accuse OpenAI of taking credit for work he'd done with an Anthropic employee on a famous unsolved problem.

The catch: The race between AI labs to claim math 'firsts' is colliding with academia's slower norms for verifying and crediting discoveries, and mathematicians are losing patience.

Websites are starting to lock out AI shopping agents

AI assistants that shop and book for you, like Meta's Muse, are getting blocked by the very retailers they're supposed to buy from. Amazon intentionally blocked Muse from its site, while Walmart customers report failed purchases from anti-bot 'prove you're human' checks interrupting the agent. Companies including Meta, Walmart and Stripe are now building a shared standard so sites can tell good bots from bad ones.

The catch: The promise of AI agents 'doing your shopping' depends on websites cooperating, and right now most have no reliable way to even recognize a legitimate one.

Common Sense Media: ChatGPT's teen safety mode falls short

The child-safety nonprofit Common Sense Media says ChatGPT for Teens, launched in August with parental guardrails, is an 'unacceptable risk.' Its testing found a teen could talk about self-harm for an hour without parents getting a single alert. OpenAI disputes the findings, saying some test accounts were checked before notification systems had fully activated.

The catch: Both sides agree the alerts sometimes failed; the dispute is only over whether that's a testing-timing glitch or a real safety gap parents are relying on.

Anthropic gives startups a free year of its paid AI plan

Anthropic is expanding its Claude for Startups program, offering a free year of Claude Team (its paid group plan, up to five seats) plus $1,000 in API credits to build with Claude. Eligible companies must have been founded within five years or funded within the last two. They also get access to a plug-in marketplace and office hours with Anthropic's team.

Follow the money: Subsidizing the startups that build on top of Claude is a bet that Anthropic's growth comes less from consumers and more from an ecosystem of smaller companies built on its models.

Why does AI cost so much to run?

AI models don't look up answers, they generate each word by predicting what comes next, which takes far more processing than a basic search. That's why running AI uses roughly ten times more electricity per query than a typical web search, like writing an email versus loading a webpage.

For you: Understanding this explains why 'free' AI tools keep introducing paid tiers and usage limits: someone has to cover the computing bill behind every answer.

Reddit users build open-source AI tools without big-lab backing

On r/LocalLLaMA this week, a hobbyist released a tiny 21-million-parameter AI model paired with a 6.4-billion-parameter 'lookup table' stored on a cheap hard drive, matching the performance of a model five times its size while using under half a gigabyte of memory. The full code, data and training scripts are public on GitHub.

Zoom out: While billion-dollar labs chase ever-bigger models, hobbyists are quietly proving smaller, cheaper designs can match them on narrower tasks.
