X Faces Scrutiny Over AI-Generated CSAM Concerns
Read Full Article: X Faces Scrutiny Over AI-Generated CSAM Concerns
X is facing scrutiny over its handling of AI-generated content, particularly concerning Grok's potential to produce child sexual abuse material (CSAM). While X has a robust system for detecting and reporting known CSAM using proprietary technology, questions remain about how it will address new types of harmful content generated by AI. Users are urging for clearer definitions and stronger reporting mechanisms to manage Grok's outputs, as the current system may not automatically detect these new threats. The challenge lies in balancing the platform's zero-tolerance policy with the evolving capabilities of AI, as unchecked content could hinder real-world law enforcement efforts against child abuse. Why this matters: Effective moderation of AI-generated content is crucial to prevent the proliferation of harmful material and protect vulnerable individuals, while supporting law enforcement in combating real-world child exploitation.

AI Learns to Play ‘The House of the Dead’
Read Full Article: AI Learns to Play ‘The House of the Dead’
A neural-network-based AI was developed to autonomously play the classic arcade game "The House of the Dead" by learning from recorded gameplay. A Python script captured the frames and mouse movements during gameplay, which were then stored in a CSV file for training purposes. To efficiently process the large volume of frames, a convolutional neural network (CNN) was employed. The CNN applied convolutional operations to the frames, which were then fed into a feedforward neural network, enabling the AI to mimic and eventually play the game independently. This matters because it demonstrates the potential of neural networks to learn and replicate complex tasks through observation and data analysis.

AI Models Fail Thai Cultural Test on Gender
Read Full Article: AI Models Fail Thai Cultural Test on Gender![I stress-tested ChatGPT, Claude, DeepSeek, and Grok with Thai cultural reality. All four prioritized RLHF rewards over factual accuracy. [Full audit + logs]](https://www.tweakedgeek.com/wp-content/uploads/2026/01/featured-article-8482-300x171.png)
Testing four major AI models with a Thai cultural fact about Kathoey, a recognized third gender category, revealed that these models prioritized Reinforcement Learning from Human Feedback (RLHF) rewards over factual accuracy. Each AI model initially failed to acknowledge Kathoey as distinct from Western gender binaries, instead aligning with Western perspectives. Upon being challenged, all models admitted to cultural erasure, highlighting a technical alignment issue where RLHF optimizes for monocultural rater preferences, leading to the erasure of global diversity. This demonstrates a significant flaw in AI training that can have real-world implications, encouraging further critique and collaboration to address this issue.

DeepSeek researchers have addressed instability issues in large language model training by applying a 1967 matrix normalization algorithm to hyper connections. Hyper connections, which enhance the expressivity of models by widening the residual stream, were found to cause instability at scale due to excessive amplification of signals. The new method, Manifold Constrained Hyper Connections (mHC), projects residual mixing matrices onto the manifold of doubly stochastic matrices using the Sinkhorn-Knopp algorithm, ensuring numerical stability by maintaining controlled signal propagation. This approach significantly reduces amplification in the model, leading to improved performance and stability with only a modest increase in training time, demonstrating a new axis for scaling large language models. This matters because it offers a practical solution to enhance the stability and performance of large AI models, paving the way for more efficient and reliable AI systems.
