1. Google paper cuts agent token usage by 94% in long sessions by tracking state instead of history
📖 背景补充：processes 100 billion tokens daily. Moonshot was awarded the Erik Riedel Best Paper Award at the USENIX FAST conference for the paper detailing the architecture

The idea: Agents keep the conversation history as part of their input while they reason. SKILL.state proposes to replace that with a structured representation of the current state,
🗣️ 高赞评论
💬 [50⬆] So is there some component that converts the conversation history into a state model? Did they name anything, don’t make me read the paper lol state compaction protocol
💬 [45⬆] This is huge. And the reduction of tokens used is really just a added benefit. The real benefit is the governance that can be applied to the agents in a deterministic manner by ensuring that the prompts, at every step, are minimal, optimal, and align
💬 [40⬆] Doesn't this argument assume a perfect user? Doesn't conversation history overcome the limitations of the operator more than the model?
🔍 我们的观察
这类讨论的背后，折射出科技从业者对自身价值的深层焦虑——不是AI本身”能不能”，而是管理层”用不用”。；AI Agent目前最大的问题不是技术成熟度，而是企业对它的预期泡沫。Reddit技术人员的主流态度是务实怀疑派。
2. Standard RAG + Vectorless RAG vs. Folder Maps/Grep for agent routing on large document corpuses?

Hey everyone, I’m trying to figure out the best routing and retrieval strategy for an agent setup (specifically using Hermes and some MCP servers) to navigate a massive corpus of c
🗣️ 高赞评论
💬 [50⬆] I'm not a RAG expert, just an enthusiast working on a similar problem, but I wonder if a third approach could be worth testing. Instead of choosing between folder/keyword search and vectorless RAG, I'd combine cheap deterministic routing with
💬 [45⬆] I have tried document inference lazily before and it never worked out well. In my experience each document is unique and using blanket OCR/embeddings never work. I'd split this into two separate problems instead of picking one paradigm for the wh
💬 [40⬆] I think the size of the corpus does really matter, hard to know what 'huge' is though. Other questions: – Acceptable latency? – Acceptable cost per query? Since that will affect whether you can have loads of follow-up calls for tree navig

Fizgig v5 is out, and the headline is one I’ve been sitting on for a while: full fine-tuning of the MiniMax H3 and Krea 2 base models – the models themselves, not a LoRA ,on consum
🗣️ 高赞评论
💬 [50⬆] thank you for your effort!
💬 [45⬆] hands down the best tool out there for training, so underated 👍
💬 [40⬆] I second this, best tool so far. The other trainers should take notes.

I’m trying to understand what a world model is. I understand it has cognitive science and reinforcement learning. I understand at least at the moment what most people are building
🗣️ 高赞评论
💬 [50⬆] There are several types of world models. Fei fei li developed a taxonomy tag might be helpful here: https://drfeifei.substack.com/p/a-functional-taxonomy-of-world-models
💬 [45⬆] The taxonomy's a decent starting point but honestly the whole term's become so overloaded it barely means anything anymore. Every lab slaps "world model" on their project and half the time it's just a diffusion model that genera
💬 [40⬆] So is it really the fact that they’re top-down learned representations? Is there actually no explicit definition of anything required for the simulation? In a way, formulas are learned relationships. Newton’s equations, for example, are approximati

🗣️ 高赞评论
💬 [50⬆] Love seeing someone actually check the benchmarks instead of just chasing the leaderboard. The fact that SPC cleans up on these datasets is pretty damning, especially when you look at how many papers treat TSB-AD like the gold standard. Makes you won

💬 [50⬆] Amazing writeup – I liked how comprehensively you laid out your thinking and the algorithmic problem-solving. I had a couple of questions if you don't mind: How do you use the readability/grade-level metrics? Are they helpful in the sense th
💬 [45⬆] Great essay! Reads like the script for a TED talk … ! Do you treat html and markdown as text? And could this be extended to handle diagrams like Miro and Figma? Have you / do you plan to open source your solution?

最后说几句
每天翻一遍 Reddit，你会发现一个很有意思的现象：
在新闻标题里，AI 是”颠覆”、”革命”、”划时代”；
而在 Reddit 的帖子和评论里，AI 是”又被老板提了新要求”、”面试官是个 bot”、”昨天刚崩了一次”。
两个版本的叙事，同时发生着。
我们更愿意相信 Reddit 那一版——因为那是活在技术第一线的人，用他们的真实感受投票出来的。
