- OpenAI’s math explosion continues with 700+ papers
- Mistral's ‘Le Chonk’ joins the West’s open-model surge

- The boldest claim is a proof of the “quasi-Riemann hypothesis,” a weaker version of math’s famous $1M puzzle on how prime numbers are spread out.
- OpenAI lists 162 papers whose main results are written in Lean, software that lets a computer verify every step of the process through proofs.
- Last month’s Navier–Stokes proof took 10,000 AI agents, but OpenAI says nearly all new results took just one prompt, averaging 3 hours of ChatGPT Pro compute.
- Levent Alpöge, the Anthropic mathematician behind July's Jacobian result, called it “obviously the most significant moment in mathematical history.”
- A WIRED report just hours earlier detailed anger among mathematicians over the drop, with some saying OAI had promised it would space out its releases.
The Rundown: A recent Pareto frontier analysis found Glean’s responses were preferred 78% of the time over Claude Cowork across 180+ tasks, at an average cost of $0.58 per task compared with $2.98.

Image source: MistralThe Rundown: France’s Mistral AI just introduced Large 4, a 1T-parameter open model nicknamed “Le Chonk,” which the company says leads every non-Chinese open system by a “substantial margin.” The details: - China's Kimi K3 still tops Mistral’s coding chart at 68%, but Le Chonk's 62% clears the 44% of Reflection AI’s Beam, the new U.S. open model launched on Monday.
- Cybersecurity is a standout, with Mistral claiming a top-5 global ranking and 82% on a bug test Claude Opus 5.5 and GPT-6 Astra mostly refused.
- For legal work, Mistral says outside tester Vals scored it at nearly 3x GPT-6 Astra on Harvey’s benchmark, ahead of every Chinese open model tested.
- Cyber experts and government agencies get a less-filtered version during a three-week preview, with weights set to go public on Oct. 27.
The Rundown: In this guide, you’ll use Astra in ChatGPT Work to compare software plans for a small team. You’ll check prices, user limits, and billing terms, then get a short recommendation with sources.Step-by-step:- Open Work in the ChatGPT desktop app, choose Astra, and open the built-in browser beside your chat. Keep website approvals on
- Give it three pricing pages and your needs, including team size, required features, and budget. Ask for monthly billing and rule out trials or purchases
- Start with one site. Check that Astra reads the right billing period and includes the full team cost before letting it compare the others
- Ask for a short recommendation using the checked facts. Keep missing details visible and review the final price yourself before buying anything
The Rundown: People are building with AI, whether IT approves or not. Pave gives them a governed lane: role-based permissions, a draft-to-publish gate, and an admin view of every connector and workflow.Why IT teams say yes to Pave:- Built on Quickbase’s 25-year enterprise platform
- Your data never trains the AI
- You can see who can do what, in one place
Image source: HarkThe Rundown: Hark, the AI startup from Figure AI founder Brett Adcock, released Hark Pro, a personal assistant for web and mobile that remembers users’ preferences, flags what needs doing, and can research, shop, book, and build things on their behalf.The details:- In Adcock’s launch video, a request for two movie tickets ends with Hark picking seats, adding the show to the calendar, and offering to reserve parking.
- Tasks run on Handoff, Hark’s own cloud computer, which the company says can work up to 36 browsers at once while showing its clicks in the chat.
- Around its chat box, the app lays out a home screen of widgets and suggested to-dos, with users also able to create ‘panels’ of customized mini-apps.
- Hark features both a free and paid tier, with an integrated family of hardware devices coming in 2027 with connectivity via a partnership with AT&T.
