🚨BREAKING: Anthropic just dropped free courses to master AI with certificates. No tuition. No waitlist. No BS. Here're 10 courses that will replace a $50K degree👇

CLIs are super exciting precisely because they are a "legacy" technology, which means AI agents can natively and easily use them, combine them, interact with them via the entire terminal toolkit. E.g ask your Claude/Codex agent to install this new Polymarket CLI and ask for any arbitrary dashboards or interfaces or logic. The agents will build it for you. Install the Github CLI too and you can ask them to navigate the repo, see issues, PRs, discussions, even the code itself. Example: Claude built this terminal dashboard in ~3 minutes, of the highest volume polymarkets and the 24hr change. Or you can make it a web app or whatever you want. Even more powerful when you use it as a module of bigger pipelines. If you have any kind of product or service think: can agents access and use them? - are your legacy docs (for humans) at least exportable in markdown? - have you written Skills for your product? - can your product/service be usable via CLI? Or MCP? - ... It's 2026. Build. For. Agents.

introducing polymarket cli - the fastest way for ai agents to access prediction markets built with rust. your agent can query markets, place trades, and pull data - all from the terminal fast, lightweight, no overhead

Clawdbot (now Moltbot) shows how fast a killer AI agent idea can turn into a security mess. The perfect example of a brilliant idea with zero security foresight. Lessons learned: • Agentic AI is game-changing, but secure-by-default is non-negotiable. • Hype moves fast, security must move faster.

New MIT + ETH Zurich + Improbable AI lab paper on scalable, low-overhead continual learning. Shows Self-Distillation Fine-Tuning improves accuracy from 80% to 89% on knowledge acquisition tasks while reducing catastrophic forgetting. It uses no extra parameters or reward models, works via in-context prompting, --- arxiv .org/pdf/2601.19897v1

Terence Tao predicts the end of math gatekeeping with AI. AI proof assistants are smashing the technical barriers that keep amateurs out. By automating verification, AI empowers anyone to contribute rigorous pro-level Math. The Ivory Tower is falling
Rohan Paul@rohanpaul_ai

AI has crossed a key threshold. Its now participating in mathematics by generating nontrivial arguments, uncovering hidden structure, and solving famous valued problems without a predefined path. We now have a working loop where AI proposes a full argument, a proof assistant (like Aristotle) mechanically checks it and then finally a human expert removes any accidental loopholes.

🇨🇳 China put 256 GW of new solar on the grid in H1-25, while the whole world added 380 GW in that same window, so China alone was 67% of global additions. For AI's progress, electricity abundance is becoming the absolute key competitive variable And now 6 months of solar additions in China > decades of solar additions in the US.
Rohan Paul tweet media
Michael Thomas@curious_founder

China added 256 GW of solar in the first half of 2025 alone. For perspective: the US has installed 262 GW of solar in its entire history. China is now adding more solar capacity in 6 months than the US built over decades.

🚨 BREAKING: China's new opensource code model beats Claude Sonnet 4.5 & GPT 5.1 despite way fewer params. SWE-Bench Verified (81.4%), BigCodeBench (49.9%), LiveCodeBench v6 (81.1%) - with just 40B-param model. IQuest-Coder from Quest Research, backed by China’s quant hedge fund giant UBIQUANT. UBIQUANT has leaned hard into AI for years, running teams like AILab, DataLab, and Waterdrop Lab. As of Q3 2025, AUM sat at CNY 70–80B ($10.01–11.43B), with about 24% average returns from Jan to Nov 2025, and CNY 463M ($66.18M) paid out in dividends. Bifurcated post-training delivers two specialized variants—Thinking models (utilizing reasoning-driven RL for complex problem-solving) and Instruct models (optimized for general coding assistance and instruction-following). Efficient Architecture: The IQuest-Coder-V1-Loop variant introduces a recurrent mechanism that optimizes the trade-off between model capacity and deployment footprint. Native Long Context: All models natively support up to 128K tokens without requiring additional scaling techniques.

Last year my son got a job offer from OpenAI in San Francisco $450,000 total compensation While my whole family was celebrating, I sat in my basement analyzing the offer Something wasn't clicking for me First of all, $450k is an impossible amount to make Will my son be required to perform illegal activities to earn that salary? But that's not the worst I looked at pension contributions "We offer a 401k match" I had never heard of a 401k I did some research and nearly vomited It's a retirement account that depends on the stock market His entire future would depend on gambling I called the OpenAI recruiter on behalf of my son and declined the offer Fast forward a year, my son now works at SAP making a crisp €47,000 a year He has 32 days paid vacation and his pension is guaranteed by the state My wife keeps saying I "threw his life away" She could not be more wrong I actually saved his life from being destroyed by America

#sass latency table & instructions reordering: redplait.blogspot.com/2025/11/sass-l… 1. latency tables extracted from nvdisasm are totally useless 2. instruction reordering can give speedup 3-4% (and even theoretically only 10%)

@MayraDo57466678 Antes que nada aclaro que lo único de zurdo que tengo es la escritura. El problema con Cuba es que -la gente- no puede comercializar (vender) hacia otros países y ganar dinero. Comprar si. Eso obliga a empobrecer cada vez más.

I’m starting to get into a habit of reading everything (blogs, articles, book chapters,…) with LLMs. Usually pass 1 is manual, then pass 2 “explain/summarize”, pass 3 Q&A. I usually end up with a better/deeper understanding than if I moved on. Growing to among top use cases. On the flip side, if you’re a writer trying to explain/communicate something, we may increasingly see less of a mindset of “I’m writing this for another human” and more “I’m writing this for an LLM”. Because once an LLM “gets it”, it can then target, personalize and serve the idea to its user.
