学术界最近一年的“正确”打法：
做一个 solid work，克制地讲清楚贡献 ❌
四大 / 基模团队 affiliation + overclaim + hype ✅

一个实验，三分结果，十分叙事。
昨天用表征学习重新定义智能，今天用neuron重新定义训练。

Update: After 17 days, they finally found my MacBook. Inefficient process, but thanks so much anyway!

@_lyraaaa_ Just steering neurons L14 N8949 also works. There is no significant infulence with L13 N7956. Anyway, interesting finding. Remind me with the paper from Anthropic: https://t.co/3dE8tviF7m

@Steven1521426 Nice job bro👏 Looking forward to more interesting projects from you

[Zucan Lyu @zucan_lv]

@AlaskaAir After 10 days, still no update. I tried calling your service line today — 10 minutes on hold, no agent. It's unbelievable that my MacBook left on board still hasn't been found after 10 days, and getting any real help from your team feels impossible. What a shame!

@_reachsumit Thank you for sharing our work! I devoted the first half of 2026 to completing this project and I am really proud of this work.

Self-improving data synthesis can scale embedding models across domains and tasks

@zucan_lv et al generate retrieval training data from an unlabelled corpus & a few examples refining its own synthesis instructions via feedback

Memory need not belong to a layer.

🧠 Memory need not belong to a layer.

Excited to share our new work uTTT (Universal Test-Time Training): one fast-weight memory shared by every layer of the network. Same state, same compute, better long-context retrieval and view synthesis.

@bojie_li @zhengzihan1996 一直想要这个功能🤩

[Zucan Lyu @zucan_lv]

@Alibaba_Qwen Do you will release a tech report? Looking forward to it.

[Zucan Lyu @zucan_lv]

@LiZhaoyi13 Congrats!

@xhluca @karpathy Maybe you can ask it with the question "Are you gemini3?"🤔

[Zucan Lyu @zucan_lv]

@xhluca I agree🙋‍♂️
