**Daily**

- We bought the whole GPU, so we're damn well going to use the whole GPU

- **New megakernel** for tensor-parallel inference with Llama-70B on H100s achieves **>22%** higher throughput than SGLang by optimizing resource usage across compute, memory, and communication operations.

- Fp8 runs ~100 tflops faster when the kernel name has "cutlass" in it

- The **persistent attention kernel** rewrite enhances performance at low contexts, but **fp16** performance suffers at larger contexts due to a **ptxas instruction scheduling issue** in the softmax partition, while **fp8** shows a significant speed increase when using "cutlass" in the kernel name.

- Microsoft CTO says he wants to swap most AMD and Nvidia GPUs for homemade chips

- **Microsoft aims to primarily utilize its own AI chips** in data centers, reducing dependence on Nvidia and AMD, as indicated by CTO Kevin Scott during a recent discussion at Italian Tech Week.

- Be Worried

- **AI's influence on human behavior is profound and immediate**, as it operates without the need for intelligence, raising concerns about societal control through non-sentient systems.

- Researchers develop molecular qubits that communicate at telecom frequencies

- **Molecular qubits** developed by researchers can communicate at **telecom frequencies**, bridging light and magnetism, which positions them as essential components for future **quantum networks** and technologies.

- 
D: I’m looking for papers, preprints, datasets, or reports where an LLM is trained to only know what humans knew before a major scientific breakthrough, and is then asked to propose a new theoretical framework without using post-breakthrough knowledge and without requiring experimental validation.

- **Training an LLM** on historical physics texts up to 1904 could yield novel theoretical frameworks, challenging the model to generate ideas without modern scientific knowledge or experimental validation.

- Move over Dijkstra: New Algorithm Just Rewrote 70 Years of Computer Science

- A **new algorithm** developed by a team at Tsinghua University has shattered the **“sorting barrier”**, achieving a deterministic O(m log^(2/3) n)-time complexity for single-source shortest paths, thus challenging the long-standing dominance of Dijkstra’s algorithm.

- 
R: New paper: LLMs don't have privileged self knowledge, which means we can efficiently train a General Correctness Model to predict the correctness of multiple models. Surprising or expected?

- **LLMs lack privileged self-knowledge**, meaning they do not predict their own correctness effectively; instead, they excel when trained as a **General Correctness Model (GCM)** that evaluates multiple models simultaneously.

- Learning to Reason for Hallucination Span Detection

- **LLMs** often produce **hallucinations**, and this study reveals that **Chain-of-Thought (CoT) reasoning** can enhance the detection of hallucinated spans, yielding at least one correct identification upon multiple samplings.

- 
P: Building a Music Search Engine + Foundational Model on 100M+ Latent Audio Embeddings

- **EmergeSound.ai** leverages **100M+ audio embeddings** to enable users to **query by sound**, enhancing music discovery beyond traditional text-based searches.

- VideoNSA: Native Sparse Attention Scales Video Understanding

- **VideoNSA** enhances video understanding in multimodal language models by integrating **Native Sparse Attention** (NSA) with a focus on maintaining coherence across long time scales, achieving superior performance on various benchmarks.

- 
D: Will fine-tuning LLaMA 3.2 11B Instruct on text-only data degrade its vision capabilities?

- **Fine-tuning LLaMA 3.2 11B Instruct on text-only data may risk multimodal forgetting, potentially impairing its image processing capabilities.** This concern arises from the hypothesis that training on a single modality could diminish performance in others, particularly in tasks like OCR.

- Addressing Pitfalls in the Evaluation of Uncertainty Estimation Methods for Natural Language Generation

- **Hallucinations**, particularly **confabulations**, significantly compromise the reliability of large language models (LLMs) due to their predictive uncertainty, necessitating improved evaluation methods for uncertainty estimation in natural language generation (NLG).

- DiFFPO: Training Diffusion LLMs to Reason Fast and Furious via Reinforcement Learning

- **DiFFPO** introduces a novel framework for training **masked diffusion large language models (dLLMs)**, enhancing their reasoning speed and accuracy through **reinforcement learning (RL)**, which significantly improves sample efficiency and task performance.

- Constrained Adaptive Rejection Sampling

- **Constrained Adaptive Rejection Sampling (CARS)** enhances sample efficiency in constrained language model outputs by adaptively ruling out invalid continuations, ensuring that only valid samples are generated without distorting the model's distribution.
