🎯 Transformer architecture β€’ Limits of understanding LLMs β€’ Transformer learning resources
πŸ’¬ "Knowing how a transformer works wasn't very useful at all in my day job" β€’ "Most of us confidently claimed even back in 2023 that LLMs would never be able to perform well on novel coding or mathematics tasks"
πŸ€– AI MODELS

GLM-4.7 Model Release

+++ Chinese startup Z.ai drops a heavyweight thinking model with genuinely impressive benchmarks on code tasks, though the "run it locally" crowd will need serious hardware and the patience of a distributed systems engineer. +++

How to run the GLM-4.7 model locally on your own device (guide)

"* GLM-4.7 is Z.ai’s latest thinking model, delivering stronger coding, agent, and chat performance than GLM-4.6 * It achieves SOTA performance on on SWE-bench (73.8%, +5.8), SWE-bench Multilingual (66.7%, +12.9), and Terminal Bench 2.0 (41.0%, +16.5). * The full 355B parameter model requires **400G..."

🎯 Video streaming optimization β€’ TCP congestion control β€’ Adaptive video encoding
πŸ’¬ "The actual problem with the latency was that they had frames piling up in buffers between the sender and the receiver." β€’ "Ultimately, the problem here is a lack of bandwidth estimation."
🌐 POLICY

Policy-to-Executable Rules for AI Governance

+++ Researchers tackle the unglamorous problem of converting regulatory word salad into executable rules, because apparently "comply with principles" doesn't compile. +++

[R] Policy→Tests (P2T) bridging AI policy prose to executable rules

"Hi All, I am one of the authors of a recently accepted AAAI workshop paper on executable governance for AI, and it comes out of a very practical pain point we kept running into.

Mitigating Forgetting in Low Rank Adaptation

"Parameter-efficient fine-tuning methods, such as Low-Rank Adaptation (LoRA), enable fast specialization of large pre-trained models to different downstream applications. However, this process often leads to catastrophic forgetting of the model's prior domain knowledge. We address this issue with LaL..."

Bottom-up Policy Optimization: Your Language Model Policy Secretly Contains Internal Policies

🎯 Suspicious Paper Findings β€’ Divergence in Results β€’ Incremental Modifications
πŸ’¬ "I'm feeling a bit suspicious of this paper." β€’ "The difference with TRM is that they change the trick not to backpropagate on every loop, and they do more token mixing because the FFN is not element-wise, which is overall a bit like hiding the incremental modifications on TRM without claiming how derivative these models are."
