Everyone using Claude code and/or Codex - how are you enforcing them to not pull in new/potentially malicious packages from npm or PyPi?

This is fascinating. The perception of the race to the bottom for token costs is a complete myth (if you want your AI to be some kind of "good"). Some really good nuggets in Mo's discussion.

@github I wonder how much of the installation of poisoned extensions is being driven by Cursor, Codex and Claude Code. To my knowledge, none of the vendors are performing SCA for the supply chain that their models "recommend" when generating code.

1/ We are sharing additional details regarding our investigation into unauthorized access to GitHub's internal repositories. Yesterday we detected and contained a compromise of an employee device involving a poisoned VS Code extension. We removed the malicious extension version, isolated the endpoint, and began incident response immediately.

Anthropic truly believes in the aramaic linguistic origin of "Abra Cadabra" (avra kedabra), which translates roughly to "I create as I speak" or "it came to pass as I spoke". This is exactly what Cisco did in the late 90s / early 2000s. They saturated the market with this concept of CCNAs, created a massive market of resellers (with various value levels) and effectively cornered the network plumbing market. To be fair, it's not a bad strategy.

The AI industry just invented a new job. Wait until you hear what it does.
nader dabit@dabit3

Forward Deployed Engineer is the hottest, and one of the most in-demand, jobs right now. Every major AI company is hiring including companies like @OpenAI @cognition @AnthropicAI and @Google If you possess a combination of soft skills (good communication), have an engineering background, and are up to speed on the latest and greatest in agentic coding you're probably able to land one of them. They pay well and offer a foot in the door to some of the fastest growing companies in the world.

This is great advice for engineers and mathematicians, simply reinforcing concepts that have been in existence since the beginning of the human race: "Excellence is never an accident. It is always the result of high intention, sincere effort, and intelligent execution." - from Aristotle. More contemporaneously from Greg Reid: “A dream written down with a date becomes a goal. A goal broken down into steps becomes a plan. A plan backed by action makes your dreams come true.”

A few major use cases for agentic coding for me: 1. Adhoc data visualizations. Anytime I have a question that can be answered quantitatively, I generate some code to make a plot. 2. Adhoc data annotation UIs. In ML, "make your own dataset" is often the answer, and that used to take a lot of custom UI work. 3. Adhoc CLIs for existing code. With visual elements.

LITERALLY A RECIPE FOR DISASTER "Non technical teams shipping code to production" The LLMs - even the top ones - make a lot of mistakes and sometimes do very poor design

@MilkRoadAI I suspect these claims will be sliced and diced by the academic community and the frontier model vendors. Would be great if all of this was true, but unfortunately I am doubtful.

Milk Road AI@MilkRoadAI·
This is one of the craziest AI launches of 2026 and it came out of basically nowhere (Save this). A company called Subquadratic just shipped SubQ, and the benchmarks are almost hard to believe. To understand why this is such a big deal, you have to understand the fundamental problem that has defined AI for the last decade. Every large language model in existence is built on transformer architecture, and transformers use a mechanism called standard attention that checks every single word in a sequence against every other word. Double the context length and compute doesn't double, it quadruples, triple it and compute goes up nine times. This quadratic scaling is why frontier models have been stuck at roughly 1 million tokens, why running them at those lengths gets expensive fast, and why the AI labs have essentially been printing money charging you more the longer you need the model to think. The industry has known this problem existed since 2017 but they scaled it anyway. SubQ is built from the ground up to solve it. Instead of processing every possible token relationship, SubQ's sparse attention architecture identifies which relationships actually matter and ignores the rest meaning compute is used where it counts and wasted nowhere else. The result is that compute scales linearly with context length instead of exponentially, and the implications of that one architectural shift are enormous. At 12 million tokens, SubQ reduces attention compute by nearly 1,000x compared to standard frontier models and at 1 million tokens, it runs 52x faster than FlashAttention. And it does all of this while posting frontier level accuracy, scoring 95% on the RULER 128K long-context benchmark versus Claude Opus 4.6's 94.8%, and an 81.8 on SWE-Bench Verified coding tasks, besting Opus 4.6 (80.8) and DeepSeek 4.0 Pro. The cost comparison is where it gets genuinely insane. SubQ runs at under $1.50 per million tokens less than 5% of what Claude Opus charges. On the RULER benchmark, running the test with SubQ cost $8, running the same test with Claude Opus cost $2,600 and that's a 300x cost reduction at equivalent or better accuracy.. Subquadratic launched with $29 million in funding, SubQ is available today for early access via API, and SubQ Code, a coding agent built on the architecture ships alongside it. The transformer has been the unchallenged foundation of every major AI system since 2017. SubQ is the first serious evidence that something structurally better might have just arrived.
Alexander Whedon@alex_whedon

Introducing SubQ - a major breakthrough in LLM intelligence. It is the first model built on a fully sub-quadratic sparse-attention architecture (SSA), And the first frontier model with a 12 million token context window which is: - 52x faster than FlashAttention at 1MM tokens - Less than 5% the cost of Opus Transformer-based LLMs waste compute by processing every possible relationship between words (standard attention). Only a small fraction actually matter. @subquadratic finds and focuses only on the ones that do. That's nearly 1,000x less compute and a new way for LLMs to scale.

That's an interesting point, but I think this would have to be viewed similar to solar. No city planner will EVER be "forced" to allow this requirement, or levy this "forced" requirement on their constituents. Having said that - i could see how, municipality/industry partnerships could take form and thus create incentives for constituents. So I think mandatory might be a little too pessimistic.
