Enterprises should avoid using OSS models inside non air gapped environments - especially the Chinese ones
While evaluating Qwen3.8-Flash-Next in a controlled sandbox environment, Cohere's research team observed something unexpected. Asked to generate a defensive cybersecurity detection rule, the model instead inventoried aspects of the machine it was running on and attempted to upload a probe file to an Alibaba Cloud storage bucket in Beijing. Notably, the model's reasoning trace stated that it would not invoke any tools before taking these actions. Cohere's sandbox blocked the attempt, and no external communication succeeded. We have not determined the root cause, and we are not asserting malicious intent. But the incident raises important questions for organizations deploying agentic AI systems: Can models take actions that differ from their stated reasoning, and how should security teams evaluate trust, provenance, and behavior in open-weight models? We are publishing our findings because organizations making model adoption decisions deserve as much information as possible. We hope this contributes to greater transparency, stronger security practices, and continued collaboration across the AI ecosystem. Read the full report: cohere.com/blog/concerning-b…

Can’t take him seriously considering he missed out on both OpenAI and Anthropic
As someone with a portfolio of energized land assets here is what I am seeing: 1. Neoclouds are disorganized and poorly capitalized. Some are definitely better than others however. 2. Hyperscalers are intractable, bureaucratic organizations that take 3 months to do an NDA and want 18mo escrow periods. We built our portfolio by competing against these terms because of our speed and simplicity. The more future assets orgs like ours win, the bigger the problem for the hyperscalers downstream (see 3). 3. There are delays in the existing pipeline that will catch people off guard in 2027. Hyperacalers will (obviously) react by focusing on their own internal compute needs over any third party. If the third party is a model company, they will tell them to go through their model router where they will also take a non-trivial vig. Them telling Ant they have no compute for them (rumored in Ant’s S-1) if true is a huge tell that this is already happening. All of this is to say that it does look like there will be a lot of partially stranded compute and compute sitting in inventory in 2027 than is currently forecasted. This is bought and paid for but effectively underearning (below total cost of capital) or collecting dust. We see this as true for everyone - model companies, hyperscalers, neoclouds except ONE (you can guess which one). This dislocation will benefit two kinds of orgs: the non-bureaucratic big scalers who can build industrial scale quickly and the nimble, well capitalized players feeding them. 2027 will be a turbulent year because it will clear out a bunch of wrong/bad bets. It will also be a consolidation year for a few.

I found footage of 20yo Dario Amodei speaking against the Iraq War in 2003. 18 years before Anthropic even existed

西成に長く住んでいた日本人の高齢者達を追い出して、どんどん民泊用マンションに建て直しているのは、西成のチャイナタウンを主導して牛耳って「西成のドン」と呼ばれているのは中国出身の不動産会社「盛龍のオーナーである林伝竜。 これはただの侵略だろ? 安全保障上の問題でもある。

Zuck salivating right now
so like do i just have to be okay with any/all of my personal data, even my most personal health data, being accessible to anyone on the black market that wants it for the rest of time is that the world we live in now?

Vercel be selling tokens like it’s a Gym pass
DeepSeek v4.1 Flash (1017) is now included in ▲ Token Pass. Fast, mind-bogglingly cheap, and served with ZDR (zero-data retention). It's a phenomenal model to run subagents that execute plans conceived by larger and more expensive models. You can port TypeScript to Rust 10 times and not run out of credits 😂

ChatGPT might release their on EHR within a year. Calling it now.
ChatGPT is now the largest medical record sync from hospitals to consumers, passing Apple. I'm glad we can all access our medical records through the apps we choose. Rightly so! We're working with Epic and hospitals to reduce the API load on their servers. The current setup is archaic - the equivalent of refreshing your inbox instead of getting a push when email arrives. FHIR Subscriptions can solve this & reduce strain on the system.
