- 原文: "Love this work from Aksel and the post-training team at Hugging Face! Turns out the HF ecosystem (papers, datasets, models all accessible through CLI, skills and md files) is perfect for running SOTA ML agents: agents that can train any type of AI model to top performance. A few concrete runs: ⭐️ Scientific reasoning: the agent walked citations from the benchmark paper, pulled OpenScience and NemoTron-CrossThink, added 7 difficulty-filtered variants from ARC/SciQ/MMLU, and ran 12 SFT ablations on Qwen3-1.7B. GPQA went from 10% to 32% in under 10 hours. Claude Code's best on the same prompt was 22.99%. ⭐️ HealthBench: it judged the existing datasets too noisy (!), generated 1100 synthetic examples covering emergencies, hedging and multilingual cases, upsampled 50x, and beat Codex by 60% (careful to check overfitting here) ⭐️ Competitive math: wrote a full GRPO script, launched A100s on HF Spaces, watched rewards climb and then collapse, and ran ablations until it found a recipe that held. And the harness is pretty tiny and simple. A couple of best practices and a handful of skills pointing at tools already in the ecosystem: arxiv and" for reading, the Hub for datasets and models, HF Jobs for compute, Trackio for metrics. Personal favorite is the "research skill" explaining how to do a SOTA landscape of a field (see ") which is extremely powerful when combined with a simple prompt that basically tell \"FIRST: Search HF ecosystem to find the best approach) (see" ") On another note: setting good baselines on new benchmarks keeps getting harder when a setup this simple beats raw Codex by 60% on HealthBench out of the box. Give it a try if you're training AI models. We provisioned $1k of GPU resources and Anthropic credits for the quickest among you. Links: Github (CLI):" "Spaces (mobile):" huggingface.co

Too many young men have died already; this war needs to stop. Community note The Dutch intelligence (MIVD) estimate is for 1.2 million total Russian casualties (killed, wounded, etc.) since 2022, including >500,000 deaths—not 1.2 million killed. Ukrainian casualties are ~500,000.

- 原文: "If you’re not making many mistakes, you must not be learning much. Mistakes and failures are ultimately more valuable to you than successes because they provide the best learning. I detailed some of my biggest mistakes—and what I learned from them—as part of the new MasterClass Executive program. At this stage in my life, I believe the most important thing I can do is to pass along everything I’ve learned to others, hoping that they find value in it and can avoid making the same mistakes I’ve made. If you’re interested in the program, you can apply for one of the limited spots here:"

- 原文: TPU 8i is co-designed with our Gemini research team to support low latency inference. Among the attributes that support this are large amounts of on-chip SRAM, enabling more computations to be done on chip without having to go to HBM for weights or KVCache state as often. The boardfly network topology (see image below) offers a much lower diameter network to connect all 1152 chips in an 8i pod, by fully connecting all 4 chips on the board together, fully connecting groups of 8 boards together, and then fully connecting 36 groups of 8 boards together. In addition, there is specialized Collectives Acceleration Engine (CAE) circuitry on each chip to offload various kinds of reductions and other global operations from the main computational portion of each chip, reducing on-chip latency by up to 5x. Together, these features will offer very high throughput for large-scale models (including MoEs, which often require mapping onto many chips for inference), and will do so at very low latency. This will make agentic workloads and interactive usage really shine on the TPU 8i.

- 原文: "Many people talk about Al as a threat, but l've always seen it as a partner to help me in my decision making. In 2017, I delivered this Ted Talk sharing a tool I had developed at Bridgewater: embedding our firm's decision-making principles into algorithms. My goal has always been to have an idea meritocracy in which there is meaningful work and meaningful relationships—a place where the best ideas win out over the human bias, emotion. and blind spots that often led us astray. This talk shows how AI helped achieve that. That idea, which was radical at the time, is no longer a \"future\" concept. Whether you like it or not, algorithmic decision-making is coming at you fast, and it's going to change your life. This is the foundation of my new AI twin, Digital Ray. Currently in beta, Digital Ray isn’t just a chatbot—it’s a system trained on decades of principles and pattern recognition, designed to think as I do. Consider it a tool to stress-test your own perspective for sharper, more confident choices." youtube.com

- 原文: By recognizing the higher-level consequences nature optimizes for, I've come to see that people who overweigh the first-order consequences of their decisions and ignore the effects of second- and subsequent-order consequences rarely reach their goals. This is because first-order consequences often have opposite desirabilities from second-order consequences, resulting in big mistakes in decision making. For example, the first-order consequences of exercise (pain and time spent) are commonly considered undesirable, while the second-order consequences (better health and more attractive appearance) are desirable. Similarly, food that tastes good is often bad for you and vice versa.

- 原文: "Let me say this clearly: LLMs cannot feel emotions. Emotions are evolutionary mechanisms. They push us to avoid danger or approach what is beneficial. We experience emotions because we are alive, and we want to stay alive. LLMs are not alive. Yes, emotional language may be encoded somewhere in the LLM. Yes, it may even be associated with some LLM output. But that is just a superficial property. There is nothing deeper behind it. For a very simple reason: LLMs do not have an intrinsic and inescapable drive to stay alive. This is what we call “motivation fault line” in our paper describing seven fault lines between human and artificial intelligence. * Paper in the first reply"
