i don’t think it must have more upvotes. the key issue is why those above it are seemingly no better or even much worse. this tweet is not against hf daily papers but against the filthy corruption. so many papers with a lot of upvotes but no real discussion, that might be something that u should think how to improve. i know a lot of people just asked their friends or even bought upvotes, and clicking an upvote has no cost and effort at all, just like today’s github stars. 

tbh i love hf daily papers as it helps a lot with my very limited attention and time to catch up with today’s ai. but now I just feel sad it is becoming worse

one thought about possible misunderstanding: here we are discussing more about strategic use of models instead of technical methods. we did things like imagining moe really playing like experts or setting up a task router to save costs but found them hard to work well. here what I am seeing is more about a rough standard of choosing different models. q and a and very simple agentic tasks like problems solved by using tools once or twice or fixing a small bugs, compared with building a large code projects or doing ml experiments and evals, etc.

Junyang Lin (@JustinLin610) — Tue, 14 Jul 2026 11:21:57 GMT

i recently discussed with some friends about the strike of model effects and costs. while frontier models are smashing a lot of things it is always expensive to use them. me personally always think about using as many tokens as possible with my subscriptions and coding plans, and i think if i turn the usages to tokens that might be a much bigger amount of money (i remember a media previously said if u use codex crazily u can use over 8000 dollars a month with 200 dollar subscription. not sure about the number). 

how about enterprises that really use tokens and count expense on the unit of token? some interviewees told me that they tried their design their system by tasks, like easier or to say more formatted tasks go to seed, qwen, dpsk, harder tasks like agentic tasks go to fable or sol. glm 5.2 is nice for coding but still after claude and gpt, recent grok is a bit similar. 

this just reminds me that if we design the system well on the user side, we can have more productivity based on sufficient usage of ai today without too much worry about expense. maybe there is still much room for this.

XLANG NLP Lab@XLangNLP

Two years ago, we built OSWorld 1.0 — the benchmark that became the standard for computer-use agents. Agents now score 83.5% on it. Problem solved?

Not even close.

🚀Today we introduce OSWorld 2.0: Benchmarking Computer Use Agents on Long-Horizon Real-World Tasks.

What's new:
🎯 108 real-world workflows, each ~1.6 hours ⏱️ for a skilled human
⚙️ ~318 tool calls/task vs. ~30 in OSWorld 1.0
🌍 Grounded in authentic artifacts & stateful user profiles
⚡ Captures real phenomena: dynamic environments, streaming interaction, cross-source reasoning, implicit-state inference & more

📊 Best results: Claude Opus 4.8 reaches the highest accuracy at 20.6%, while GPT-5.5 is far more token-efficient but plateaus near 13%. No one is close to solving real computer use.

Junyang Lin (@JustinLin610) — Mon, 13 Apr 2026 17:54:58 GMT

i do like this passage, and here are some thoughts:

1. critical thinking is essential in the era of agents. i still remember that many years ago when i studied the lesson of critical thinking, i learned that keeping debating with yourself by listing out reasons can really deepen your thinking. today, critical thinking becomes humans debating with agents, so that they can think more deeply together and analyze problems in a more comprehensive way.

2. designing a healthy and well-structured organization and system is essential for creation and building. with systematic support and efficient tooling, humans can work exponentially more effectively together with agents. that gives people more time to take care of their physical and mental health, while also exploring new opportunities.

3. new era often favors newbies, because they have less past experience and therefore less fear of current difficulties. what oldbies should really think about is which parts of their experience are actually worth leveraging. from my perspective, we should think more carefully about which experiences are truly aligned with first principles.

but anyway, ai first is super, super exciting!
