Cyc: The $200M AI That Never Was

2025-04-08

This essay details the 40-year history of Cyc, Douglas Lenat's ambitious project to build artificial general intelligence (AGI) by scaling symbolic logic. Despite a $200 million investment and 2000 person-years of effort, Cyc failed to achieve intellectual maturity. The article unveils its secretive history, highlighting the project's insularity and rejection of alternative AI approaches as key factors contributing to its failure. Cyc's long, slow demise serves as a powerful indictment against the symbolic-logic approach to AGI.

Meta's Llama 4: Second Place Ranking and a Messy Launch

2025-04-08

Meta released two new Llama 4 models: Scout and Maverick. Maverick secured the number two spot on LMArena, outperforming GPT-4o and Gemini 2.0 Flash. However, Meta admitted that LMArena tested a specially optimized "experimental chat version," not the publicly available one. This sparked controversy, leading LMArena to update its policies to prevent similar incidents. Meta explained that it was experimenting with different versions, but the move raised questions about its strategy in the AI race and the unusual timing of the Llama 4 release. Ultimately, the incident highlights the limitations of AI benchmarks and the complex strategies of large tech companies in the competition.

One-Minute Videos from Text Storyboards using Test-Time Training Transformers

2025-04-08

Current Transformer models struggle with generating one-minute videos due to the inefficiency of self-attention layers for long contexts. This paper explores Test-Time Training (TTT) layers, whose hidden states are themselves neural networks, offering greater expressiveness. Adding TTT layers to a pre-trained Transformer allows for the generation of one-minute videos from text storyboards. Experiments using a Tom and Jerry cartoon dataset show that TTT layers significantly improve video coherence and storytelling compared to baselines like Mamba 2 and Gated DeltaNet, achieving a 34 Elo point advantage in human evaluation. While artifacts remain, likely due to limitations of the 5B parameter model, this work demonstrates a promising approach scalable to longer videos and more complex narratives.

Multimodal AI Image Generation: A Visual Revolution Begins

2025-04-08

Google and OpenAI's recent release of multimodal image generation capabilities marks a revolution in AI image generation. Unlike previous methods that sent text prompts to separate image generation tools, multimodal models directly control the image creation process, building images token by token, much like LLMs generate text. This allows AI to generate more precise and impressive images, and iterate based on user feedback. The article showcases the powerful capabilities of multimodal models through various examples, such as generating infographics, modifying image details, and even creating virtual product advertisements. However, it also highlights challenges, including copyright and ethical concerns, as well as potential misuse like deepfakes. Ultimately, the author believes multimodal AI will profoundly change the landscape of visual creation, and we need to carefully consider how to guide this transformation to ensure its healthy development.

Real-time Neuroplasticity: Giving Pre-trained LLMs Real-time Learning

2025-04-08

This experimental technique, called "Neural Graffiti," uses a plug-in called the "Spray Layer" to inject memory traces directly into the final inference stage of pre-trained large language models (LLMs) without fine-tuning or retraining. Mimicking the neuroplasticity of the brain, it subtly alters the model's "thinking" by modifying vector embeddings, influencing its generative token predictions. Through interaction, the model gradually learns and evolves. While not forcing specific word outputs, it biases the model towards associated concepts with repeated interaction. The aim is to give AI models more proactive behavior, focused personality, and enhanced curiosity, ultimately helping them achieve a form of self-awareness at the neuron level.

Background Music Listening Habits Differ Between Neurotypical Adults and Those Screened for ADHD

2025-04-08

An online survey of 910 young adults (17–30 years old) compared background music (BM) listening habits and subjective effects between neurotypical individuals and those who screened positive for ADHD across tasks with varying cognitive demands. The ADHD group showed a significantly higher preference for BM in specific situations, such as studying and exercising, and a stronger preference for stimulating music. However, no significant differences were found in subjective effects of BM on cognitive and emotional functioning between the groups. The study highlights the importance of adjusting BM use based on individual arousal needs and available cognitive resources, offering a novel perspective on music interventions for ADHD.

Do LLMs Understand Nulls? Probing the Internal Representations of Code-Generating Models

2025-04-07

Large language models (LLMs) have shown remarkable progress in code generation, but their true understanding of code remains a question. This work investigates LLMs' comprehension of nullability in code, employing both external evaluation (code completion) and internal probing (model activation analysis). Results reveal LLMs learn and apply rules about null values, with performance varying based on rule complexity and model size. The study also illuminates how LLMs internally represent nullability and how this understanding evolves during training.

LLM Elimination Game: Social Reasoning, Strategy, and Deception

2025-04-07

Researchers created a multiplayer "elimination game" benchmark to evaluate Large Language Models (LLMs) in social reasoning, strategy, and deception. Eight LLMs compete, engaging in public and private conversations, forming alliances, and voting to eliminate opponents until only two remain. A jury of eliminated players then decides the winner. Analyzing conversation logs, voting patterns, and rankings reveals how LLMs balance shared knowledge with hidden intentions, forging alliances or betraying them strategically. The benchmark goes beyond simple dialogue, forcing models to navigate public vs. private dynamics, strategic voting, and jury persuasion. GPT-4.5 Preview emerged as the top performer.

Model Context Protocol (MCP): The Next Big Thing for LLM Integration—But With a Catch

2025-04-06

Model Context Protocol (MCP) is emerging as the standard for Large Language Model (LLM) integration with tools and data, dubbed the "USB-C for AI agents." It enables agents to connect to tools via standardized APIs, maintain persistent sessions, run commands, and share context across workflows. However, MCP isn't secure by default. Connecting agents to arbitrary servers without careful consideration can create security vulnerabilities, potentially exposing shell access, secrets, or infrastructure via side-channel attacks.

SeedLM: A Novel LLM Weight Compression Method Using Pseudo-Random Number Generators

2025-04-06

Large Language Models (LLMs) are hindered by high runtime costs, limiting widespread deployment. Meta researchers introduce SeedLM, a novel post-training compression method using seeds from a pseudo-random number generator to encode and compress model weights. During inference, SeedLM uses a Linear Feedback Shift Register (LFSR) to efficiently generate a random matrix, linearly combined with compressed coefficients to reconstruct weight blocks. This reduces memory access and leverages idle compute cycles, speeding up memory-bound tasks by trading compute for fewer memory accesses. Unlike state-of-the-art methods requiring calibration data, SeedLM is data-free and generalizes well across diverse tasks. Experiments on the challenging Llama 3 70B show zero-shot accuracy at 4- and 3-bit compression matching or exceeding state-of-the-art methods, while maintaining performance comparable to FP16 baselines. FPGA tests demonstrate that 4-bit SeedLM approaches a 4x speed-up over an FP16 Llama 2/3 baseline as model size increases.

LLMs Crack a Byzantine Music Notation Cipher

2025-04-04

Researchers discovered that large language models like Claude and GPT-4 can decode a peculiar cipher based on the Byzantine music notation Unicode block. This cipher resembles a Caesar cipher, but with an offset of 118784. The models can decode this cipher directly without chain-of-thought, achieving even higher success rates than with regular Caesar ciphers. Researchers hypothesize this is due to a linear relationship between addition in a specific Unicode range and addition in token space, allowing the models to learn a shift cipher based on this relationship. This phenomenon suggests the existence of yet-ununderstood mechanisms within LLMs.
