Quoting Jake Boggan simonwillison.net
I was a graph theory junkie long ago and even moved to Budapest for awhile to study among the greats. While I was there I started working on Barnette’s Conjecture which came to occupy my thoughts over the next 24 years of my life, on and off as I worked in many different fields. Last summer I even thought for a few days that I had actually solved it. But it’s supposedly proven here - problem 180 . I don’t know what to think exactly. I spent thousands of hours on that problem. I really enjoyed i…

We can’t just change the definition of ‘recording’ theverge.com
With AI hardware, tech companies are pushing the definition of what does and doesn’t constitute a recording. For most of gadget history, it’d be reasonable to assume that a device with a microphone or camera is either recording you or it isn’t; it’s either on or off, without much gray area. Microphones capture sound. Cameras […]

Connecting AI agents to enterprise knowledge technologyreview.com
For all the data that AI systems continually amass and analyze, enterprise AI agents often suffer from a curious shortcoming: a lack of knowledge. More than data, knowledge is the understanding of what the data means in the context of individual organizations. AI agents need this understanding to reason about situations, make decisions, and ultimately…

The ‘reduced safeguards’ do not eliminate blocks entirely; models may still refuse queries or downgrade to less capable versions at the mention of sensitive cyber tasks… some question if the program is primarily an identity collection effort rather than a true specialized access channel.
Artificial Analysis — Mistral Large 4 writeup artificialanalysis.ai
Mistral Large 4 scores 38 on the Intelligence Index, making it the most intelligent open-weight model developed outside China, though it still trails DeepSeek V4.1 Flash (39) and sits roughly 6–8 points behind leading Chinese open-weight systems like Qwen 3.8 Max and Kimi K3.
Unite.ai — ‘1.05T Le Chonk MoE in public preview’ unite.ai
Mistral is offering a version with ‘reduced moderation’ and expanded cyber capabilities to vetted partners and state authorities during the preview period, arguing provider-level refusals in Claude and GPT block legitimate security research.
Mistral.ai official announcement mistral.ai
Large 4 achieves 82% on the AA Cyber Index for reproduce-and-patch vulnerability tests, 93% on Cybench, 67% on the Finch finance benchmark, and 61.7% on DeepSWE agentic coding — with open weights scheduled for release October 27, 2026.
Wavect.io — Open-weight LLM comparison 2026 wavect.io
Running a 2.8T model like Kimi K3 requires 1.4TB of storage and multiple enterprise GPUs; Mistral Large 4’s 1T weights face similar deployment realities, meaning ‘open weights’ does not translate to local-ease for most developers who still rely on hosted APIs.

Mistral Large 4 is ‘very verbose,’ generating roughly 200M tokens during AA’s benchmark run versus a class median of 81M, pushing cost-per-task to $1.13 — about 4x DeepSeek’s $0.27 — despite a headline input price of $0.68/M tokens.
