💬 [50⬆] "argues, basically, that RSI is not on the horizon, because current (at the time the study was done) agents cannot do open-ended ML research." so because they cant do it yet, its 'not on the horizon'? how do they bridge the gap be
💬 [45⬆] There have been many several other papers that find that LLMs suck at open ended scientific research. It's not just because of the models. I highly recommend this recent survey of the topic with a bit more nuance: https://arxiv.org/pdf/2607.
💬 [40⬆] I read the abstract and I think you made a big claim that the authors don't themselves make. The paper is titled "Can agents conduct open-ended AI research?" And the last sentence of the abstract is, "Our results provide early e

💬 [45⬆] Did you text the latex conversion on your math formulas? Docling has been useful for getting tables but I run into issues with it sometimes depending on formula or table layout. Floating tables without row level lineups or sometimes resolution hits I
💬 [40⬆] Honest numbers, just pulled from the chunk DB: 2,130 formula chunks, ~960 of them contain LaTeX from Docling's formula enrichment. Most are fine (Lopez de Prado's tick rule and CUSUM definitions come through as clean cases/frac/argmin). About

💬 [50⬆] TL;DR of the discussion generated automatically after 200 comments. The consensus is this is an absolutely epic project and OP's claim of building an OS "from scratch" holds up. This isn't just a Linux reskin; a user confirmed
💬 [45⬆] Imagine asking Claude to build an os for the old classic Macs. That would be wild.
💬 [40⬆] I actually have one of those in my garage. Thank you for the idea.

YuE2 is an impressive open music model. Give it a style prompt and lyrics, and it can make a complete song. Under the hood, it generates “semantic tokens” that are then turned into

💬 [40⬆] taking steps to limit future adminsitrations is extra dastardly. there's so much cleanup work to be done already to fix the messes of the last 40 years' neoliberal and neoconservative environmental neglect

💬 [45⬆] Apparently if you write 'token' everyone loses their ability to talk about anything other than AI. XD But yeah this is rent seeking behaviour and the last time we saw this shit it was the bucketshops that preceeded the Wall Street Cash.

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。
