  Apple researchers introduce SeedLM, a novel approach to drastically compress large language model (LLM) weights. Instead of storing massive parameter sets, SeedLM generates them from a much smaller "seed" using a pseudo-random number generator (PRNG). This seed, along with the PRNG algorithm, effectively encodes the entire model, enabling significant storage savings. While SeedLM models trained from scratch achieve comparable performance to standard models of similar size, adapting pre-trained LLMs to this seed-based framework remains a challenge, resulting in performance degradation when compressing existing models. This research explores the potential for extreme LLM compression, offering a promising direction for more efficient deployment and accessibility of powerful language models.

  Apple researchers introduce a novel approach to drastically reduce the storage requirements of Large Language Models (LLMs), termed "SeedLM." This method leverages the concept of pseudo-random number generators (PRNGs) to reconstruct the vast weight matrices of LLMs from a significantly smaller "seed." Instead of storing the entire weight matrix, which can be billions of parameters, SeedLM stores only the seed used to initialize the PRNG. This seed, combined with the specific PRNG algorithm, can then be used to regenerate the weights on demand.

  The fundamental principle behind SeedLM is that the intricate patterns and structures within LLM weight matrices, while seemingly complex, might exhibit underlying regularities exploitable by PRNGs. By carefully selecting a PRNG and optimizing its parameters, the researchers demonstrate that a relatively small seed can effectively capture the essential information embedded within these weights, allowing for a substantial compression ratio.

  SeedLM's implementation involves a training process where the PRNG parameters and the seed itself are learned. This learning process aims to minimize the difference between the weights generated by the PRNG and the original, fully trained LLM weights. This optimization is performed alongside the standard LLM training, allowing the model to adapt to the weight generation process imposed by the PRNG. The researchers experiment with various PRNG architectures, including Xorshift, PCG, and SFC, finding that specific choices can significantly impact the performance of the resulting compressed model.

  The results presented demonstrate a substantial reduction in storage requirements, with compression ratios reaching several orders of magnitude depending on the specific model and PRNG configuration. While the compressed models using SeedLM do exhibit some performance degradation compared to their fully-weighted counterparts, the trade-off between storage savings and performance loss offers a compelling advantage, particularly for deploying LLMs on resource-constrained devices. Furthermore, the researchers explore different strategies to mitigate this performance degradation, including fine-tuning the compressed model after weight generation and employing higher-precision arithmetic during the PRNG weight generation process.

  The researchers highlight that SeedLM is not merely a compression technique but also offers potential benefits in terms of model personalization and efficient exploration of the model parameter space. By modifying the seed, one could potentially generate variations of the base LLM, enabling customization without retraining the entire model. This could be particularly useful for adapting LLMs to specific tasks or domains. Additionally, the compact representation provided by the seed facilitates efficient exploration of different model configurations, which could accelerate the process of finding optimal LLM architectures.

  While acknowledging that SeedLM is still in its early stages of development, the authors suggest that this approach represents a promising direction for addressing the growing storage demands of ever-larger LLMs, paving the way for their wider deployment across a range of devices and applications. Future research directions include exploring more sophisticated PRNG architectures, optimizing the training process for SeedLM, and investigating the impact of SeedLM on different LLM architectures and tasks.

A few users express excitement about the potential for smaller, more efficient models running on personal devices.

  The Hacker News thread for "SeedLM: Compressing LLM Weights into Seeds of Pseudo-Random Generators" contains several interesting comments discussing the feasibility, implications, and potential flaws of the proposed approach.

  Several commenters express skepticism about the practical applicability of SeedLM. One points out that the claim of compressing a 7B parameter model into a 100KB seed is misleading, as training requires an enormous amount of compute, negating the storage savings. They argue this makes it less of a compression technique and more of a novel training method. Another user expands on this by questioning the efficiency of the pseudo-random generator (PRG) computation itself. If the PRG is computationally expensive, retrieving the weights could become a bottleneck, outweighing the benefits of the reduced storage size.

  A related thread of discussion revolves around the nature of the PRG and the seed. Commenters debate whether the seed truly encapsulates all the information of the model or if it relies on implicit biases within the PRG's algorithm. One comment suggests the PRG itself might be encoding a significant portion of the model's "knowledge," making the seed more of a pointer than a compressed representation. This leads to speculation about the possibility of reverse-engineering the PRG to understand the learned information.

  Some users delve into the potential consequences for model security and intellectual property. They suggest that if SeedLM becomes practical, it could simplify the process of stealing or copying models, as only the small seed would need to be exfiltrated. This raises concerns about protecting proprietary models and controlling their distribution.

  Another commenter brings up the potential connection to biological systems, wondering if something akin to SeedLM might be happening in the human brain, where a relatively small amount of genetic information gives rise to complex neural structures.

  Finally, a few comments address the experimental setup and results. One commenter questions the choice of tasks used to evaluate SeedLM, suggesting they might be too simple to adequately assess the capabilities of the compressed model. Another points out the lack of comparison with existing compression techniques, making it difficult to judge the relative effectiveness of SeedLM.

  Overall, the comments reflect a mixture of intrigue and skepticism about the proposed SeedLM approach. While acknowledging the novelty of the idea, many users raise critical questions about its practical viability, computational cost, and potential security implications. The discussion highlights the need for further research to fully understand the potential and limitations of compressing large language models into pseudo-random generator seeds.

• Big LLMs weights are a piece of history

  Posted: 2025-03-16 12:13:24

  Verbose tl;dr

  Large Language Models (LLMs) like GPT-3 are static snapshots of the data they were trained on, representing a specific moment in time. Their knowledge is frozen, unable to adapt to new information or evolving worldviews. While useful for certain tasks, this inherent limitation makes them unsuitable for applications requiring up-to-date information or nuanced understanding of changing contexts. Essentially, they are sophisticated historical artifacts, not dynamic learning systems. The author argues that focusing on smaller, more adaptable models that can continuously learn and integrate new knowledge is a more promising direction for the future of AI.

  Salvatore Sanfilippo, the creator of Redis, argues in his blog post "Big LLMs weights are a piece of history" that the current practice of distributing large language models (LLMs) by sharing their weights will soon become obsolete. He posits that the sheer size and computational demands of these models are reaching a point of diminishing returns. Training these massive models requires immense resources, accessible only to a handful of large corporations, and inferencing with them necessitates significant hardware capabilities, limiting widespread accessibility and deployment.

  Sanfilippo believes the future of LLMs lies in distilling the knowledge embedded within these colossal models into smaller, more specialized models. He envisions a shift towards training smaller models on the outputs of the larger LLMs, effectively transferring the learned knowledge without needing to distribute the massive weight files. This approach, analogous to learning from a teacher rather than studying the entirety of a library, would allow for wider dissemination and utilization of LLM capabilities. Smaller, specialized models could be deployed on less powerful hardware, making them accessible to a broader range of users and applications.

  Furthermore, Sanfilippo contends that distributing the output of large LLMs, rather than the weights themselves, provides a greater degree of control and safety. By curating the output data, developers can mitigate potential biases and inaccuracies present in the larger models, resulting in more reliable and trustworthy downstream applications. This curated data then acts as a refined training set for the smaller, specialized models.

  Sanfilippo acknowledges that the output of large LLMs may not perfectly encapsulate all the nuances and intricacies of the original model. However, he argues that this trade-off is acceptable given the significant gains in accessibility, efficiency, and control afforded by utilizing smaller, distilled models. This approach, he suggests, democratizes access to advanced language processing capabilities, empowering a wider community of developers and users to leverage the power of LLMs without the constraints of massive computational resources. He concludes by expressing his excitement for this potential shift in the LLM landscape, anticipating a future where the focus moves from sheer model size to efficient knowledge transfer and specialized applications.

Others highlight the potential research value in studying these snapshots of AI development, enabling future analysis of biases, training methodologies, and the evolution of AI capabilities. A few express skepticism, questioning the historical significance of LLMs compared to other technological advancements. Some also discuss the ethical implications of preserving models trained on potentially biased or copyrighted data.

  The Hacker News post titled "Big LLMs weights are a piece of history" (linking to an Antirez blog post about the potential for using LLMs as a historical record) sparked a lively discussion with several interesting comments.

  Many commenters agreed with Antirez's core premise, acknowledging the inherent historical value embedded within LLM weights. They pointed out how these weights capture a snapshot of the data they were trained on, reflecting societal biases, cultural trends, and the state of knowledge at a specific point in time. This "fossilized" information, they argued, could be valuable for future researchers studying the evolution of language, culture, and technology. One commenter even suggested that future historians might "mine" these weights like archaeologists excavate ancient ruins.

  Several commenters expanded on the idea, discussing the potential to analyze changes in LLM weights over time to track the evolution of language and cultural shifts. They envisioned comparing different versions of a model to identify how its understanding of certain concepts changed, potentially revealing how societal attitudes evolved.

  Some commenters raised practical considerations, like the sheer size of these models and the challenges of storing and accessing them for historical analysis. They discussed the need for efficient methods to query and interpret the information encoded within the weights.

  However, not everyone agreed with the central premise. Some argued that the information contained within LLM weights is too abstract and entangled to be meaningfully interpreted as a historical record. They pointed out that the weights represent complex statistical relationships rather than explicit factual information, making it difficult to extract specific historical insights. They also questioned the reliability of these models as historical sources, given their potential biases and limitations. One commenter specifically argued that LLMs are more akin to a "compressed representation" of the training data rather than a direct historical record, potentially leading to distortions and inaccuracies.

  A few commenters also touched upon the ethical implications of preserving and analyzing LLM weights, particularly regarding privacy concerns. They raised questions about the potential to reconstruct sensitive information from the training data, highlighting the need for careful consideration of data privacy and security.

  The discussion also branched into related topics, such as the possibility of using LLMs to generate synthetic historical data and the potential for future AI systems to actively curate and preserve their own historical records.

• 16-Bit to 1-Bit: Visual KV Cache Quantization for Efficient Multimodal LLMs

  Posted: 2025-03-05 16:09:26

  Verbose tl;dr

  This paper introduces Visual Key-Value (KV) Cache Quantization, a technique for compressing the visual features stored in the key-value cache of multimodal large language models (MLLMs). By aggressively quantizing these 16-bit features down to 1-bit representations, the memory footprint of the visual cache is significantly reduced, enabling efficient storage and faster retrieval of visual information. This quantization method employs a learned codebook specifically designed for visual features and incorporates techniques to mitigate the information loss associated with extreme compression. Experiments demonstrate that this approach maintains competitive performance on various multimodal tasks while drastically reducing memory requirements, paving the way for more efficient and scalable deployment of MLLMs.

  The paper "16-Bit to 1-Bit: Visual KV Cache Quantization for Efficient Multimodal LLMs" addresses the growing computational demands of multimodal Large Language Models (LLMs), particularly those incorporating visual information. These models, while powerful, face challenges regarding memory and computational costs, especially when handling long sequences of visual data in tasks like video understanding or visual dialogue. Storing and accessing the Key-Value (KV) cache, a crucial component for maintaining context in LLMs, becomes a bottleneck due to the high dimensionality of visual features.

  The authors propose a novel quantization technique focused on compressing the visual features stored within the KV cache, reducing memory footprint and accelerating retrieval. Instead of the standard 16-bit floating-point representation, they explore aggressive quantization down to 1-bit, representing each value with a single binary digit. This dramatic reduction in precision, while potentially introducing information loss, offers significant efficiency gains.

  The core of their approach revolves around a learned, data-dependent quantization scheme. Rather than relying on standard uniform quantization methods, they introduce a trainable binary quantizer specifically tailored for visual features within the KV cache. This learned quantizer maps the high-dimensional floating-point vectors to binary codes, optimizing the preservation of crucial information for model performance.

  The paper explores two specific variants of this learned binary quantization: vector-wise and dimension-wise quantization. Vector-wise quantization treats each vector as a whole, learning a single threshold for binarization, while dimension-wise quantization learns individual thresholds for each dimension of the feature vector, allowing for finer-grained control. The authors hypothesize that dimension-wise quantization, although requiring more learned parameters, might better capture the varying importance of different feature dimensions.

  The effectiveness of their proposed method is evaluated on several multimodal benchmarks, including video question answering and visual dialogue. They demonstrate that even with extreme quantization down to 1-bit, the performance degradation remains surprisingly small, especially when employing the dimension-wise quantization strategy. This suggests that the crucial contextual information within the KV cache can be effectively represented with significantly reduced precision, leading to substantial savings in both memory and computational resources. The paper concludes that this aggressive quantization technique provides a promising pathway for deploying efficient and scalable multimodal LLMs, paving the way for broader adoption and application of these powerful models.

• LIMO: Less Is More for Reasoning

  Posted: 2025-02-09 16:33:28

  Verbose tl;dr

  LIMO (Less Is More for Reasoning) introduces a new approach to improve the reasoning capabilities of large language models (LLMs). It argues that current chain-of-thought (CoT) prompting methods, while effective, suffer from redundancy and hallucination. LIMO proposes a more concise prompting strategy focused on extracting only the most crucial reasoning steps, thereby reducing the computational burden and improving accuracy. This is achieved by training a "reasoning teacher" model to select the minimal set of effective reasoning steps from a larger CoT generated by another "reasoning student" model. Experiments demonstrate that LIMO achieves better performance than standard CoT prompting on various reasoning tasks, including arithmetic, commonsense, and symbolic reasoning, while also being more efficient in terms of both prompt length and inference time. The method showcases the potential of focusing on essential reasoning steps for enhanced performance in complex reasoning tasks.

  The preprint "LIMO: Less Is More for Reasoning" introduces a novel approach to enhance the reasoning capabilities of large language models (LLMs) by focusing on a concise and strategically selected subset of the input context, rather than attempting to process the entire input. This approach, termed "Less Is More" (LIMO), is predicated on the observation that while LLMs demonstrate impressive abilities in various tasks, they often struggle with complex reasoning problems that involve synthesizing information from lengthy or convoluted inputs. The authors hypothesize that this difficulty stems from the limitations inherent in the attention mechanisms of these models, which can become overwhelmed by the sheer volume of information present in large contexts. Furthermore, including irrelevant or distracting information can negatively impact the model's ability to focus on the crucial elements necessary for accurate reasoning.

  LIMO addresses this challenge by employing a two-stage process. In the first stage, a "selector" model, which can be a smaller and more efficient LLM or even a distinct algorithm altogether, is tasked with identifying the most pertinent sentences from the input context. This selection process is guided by the specific reasoning task at hand, aiming to extract the information most likely to contribute to a correct solution. The selection criteria can be implicitly learned by the selector model or explicitly defined based on the task's requirements.

  The second stage involves feeding the selected sentences, and only those sentences, to a powerful "reasoner" LLM. This significantly reduced context allows the reasoner to allocate its computational resources more effectively, focusing its attention on the most relevant information. By eliminating the noise and distraction of irrelevant data, LIMO aims to improve the reasoner's ability to perform complex logical deductions and generate more accurate and insightful outputs.

  The authors evaluate LIMO's performance on a range of challenging reasoning benchmarks, including HotpotQA, 2WikiMultiHopQA, and MuSiQue. These benchmarks are specifically designed to test the models' ability to synthesize information from multiple sources and perform multi-step reasoning. The results presented in the paper suggest that LIMO consistently outperforms baseline models that process the entire input context, demonstrating the effectiveness of this less-is-more philosophy. Furthermore, the authors explore different selector architectures and training strategies, offering insights into the design choices that contribute to LIMO's success. They also analyze the behavior of the selector model, providing evidence that it indeed learns to identify and prioritize the most relevant sentences for the reasoning task.

  In conclusion, the LIMO framework offers a promising avenue for enhancing the reasoning capabilities of LLMs by strategically reducing the input context to its most essential components. This approach not only improves performance on complex reasoning tasks but also offers potential benefits in terms of computational efficiency and resource utilization. The authors posit that LIMO represents a significant step towards developing more robust and reliable reasoning systems based on large language models.

  Several Hacker News commenters express skepticism about the claims made in the LIMO paper. Some question the novelty, arguing that the core idea of simplifying prompts isn't new and has been explored in prior work. Others point out potential weaknesses in the evaluation methodology, suggesting that the chosen tasks might be too specific or not representative of real-world scenarios. A few commenters find the approach interesting but call for further research and more robust evaluation on diverse datasets to validate the claims of improved reasoning ability. There's also discussion about the practical implications, with some wondering if the gains in performance justify the added complexity of the proposed method.

  The Hacker News post titled "LIMO: Less Is More for Reasoning" (https://news.ycombinator.com/item?id=42991676) discussing the arXiv paper "Less Is More for Alignment" has a limited number of comments, primarily focusing on clarification and skepticism.

  One commenter asks for clarification about the meaning of "less is more" in this context, wondering if it refers to model size, the amount of training data, or something else. They also express concern that the abstract uses vague terms and wonder if there are concrete, measurable metrics for success.

  Another commenter responds, explaining that "less" likely refers to smaller models and that the paper explores how better reasoning can emerge when these smaller models have a restricted view of context, especially in mathematical reasoning tasks. They suggest this might be because the limited context allows the model to focus on relevant information, improving its deduction capabilities. However, they also mention the authors acknowledge these benefits primarily apply to "mathematical reasoning-like tasks" and aren't necessarily generalizable.

  A third commenter expresses skepticism towards the paper's methodology, noting the specific choice of dataset (GSM8K) and questioning how applicable the findings are to other types of problems. They highlight that GSM8K primarily tests whether a model can correctly perform a sequence of arithmetic operations and propose that the limited context simply helps the model to avoid getting overwhelmed by extraneous information in this specific scenario. They imply this doesn't necessarily demonstrate a genuine improvement in reasoning abilities.

  The remaining comments are brief, with one user sharing a related paper and another providing a concise summary of the main idea presented in the LIMO paper.

  In summary, the discussion revolves around understanding the "less is more" concept in the context of the paper, specifically regarding model size and context window. There's also notable skepticism about the general applicability of the findings, with concerns raised about the choice of dataset and whether the improvements observed are truly indicative of better reasoning or simply an artifact of the task's specific structure. The overall tone is one of cautious interest with a desire for more clarity and broader validation.
