用 AI 解决问题的几个坑:
别把 AI 当低级外包。
交出底层逻辑,你会丧失全局主导权。
别闭眼收结果。
跑不懂的代码、用不知来源的数据,必踩黑盒陷阱。
要解决就解决命运级痛点,别只盯着工具层面的便利。
AI 是需要你主动引导和理解的第二大脑,关键是保持主导权。
就像带徒弟,你得懂他怎么干的。
不懂底层逻辑,别用 AI 做重大决定。
@yungsyndicate@real_hotaru Clean loop. For delayed or multi-causal skills like writing and management, step 4 has no crisp error signal, so a proxy metric plus a scheduled review can stand in for "check against reality." What proxy do you use when feedback isn't immediate?
🚀 Meet Strands Decider 2B, a small open source decision model built for fast experimentation and local development: https://t.co/rZjMiz6Rn5
It's part of a new class of decision models. Unlike reasoning models that generate open-ended text, Strands Decider 2B picks between options and assigns confidence scores. Decision models are faster and more capable at a given size, always produce an answer from the selected options, and can run with very low latency.
Strands Decider 2B is a 2 billion parameter model that runs on a local CPU or GPU and can return answers to meaningful questions in tens of milliseconds. On accuracy and calibration, it ranks second among public models in its ~2 billion parameter class, and first among those that share their full training recipe.
We're already seeing early success with model routing, tool selection, guardrails, evals, and hybrid agents that pair LLMs for the hard calls with decider models for the rote ones. Grab the code on GitHub and the latest snapshots on HuggingFace, and tell us what you build.
This space is super early and we are experimenting with different variants of these models, so give it a spin and give us feedback!
就像 Karpathy 说的,现在用 AI 学习,重点是看懂 AI 给的东西,而 AI 也越来越爱生成漂亮的网页和动画。
但这种太顺滑的演示,很容易让你产生“我懂了”的错觉。真正学会不是看懂,而是你能改条件、猜结果。
建议大家改改提示词:别让 AI 只是放动画给你看,让它出选择题或者给几个能调的参数,把答案先藏起来。先自己猜,点开再看结果。
故意给自己加点难度,才能打破错觉,真正学进脑子里。
