Mini-AGI is a continual learning byte-level language model that dynamically assembles its own architecture and trains on a single 8GB VRAM GPU. It manages weights by storing them on disk and paging them to VRAM as needed, allowing parameter count to be limited by disk space. The model can grow new capacity during training and prunes unused components. It uses the same forward pass for both generating and reading, with writing costing more depth than reading. Training on a single stream can lead to catastrophic forgetting, as seen when learning chess impacted other subjects.

A Transformer is a neural network architecture that utilizes a self-attention mechanism to integrate information across tokens. Unlike self-attention, the Multi-Layer Perceptron (MLP) within a Transformer processes tokens independently, mapping each token representation from one space to another. This process, represented by the formula QKV_{ij} = (\sum_{d=1}^{768} \text{Embedding}_{i,d} \cdot \text{Weights}_{d,j}) + \text{Bias}_j, enriches the overall model capacity.

OpenAI has revealed concerning information regarding its AI models, as detailed in a YouTube video titled "OpenAI Just Revealed Something Terrifying About Its AI Models."

Pruning large language models by removing transformer blocks, known as depth pruning, offers predictable inference speedups and memory savings, and is compatible with other optimization techniques. The challenge lies in selecting which blocks to remove, as choices interact, making it a combinatorial problem. This problem can be modeled using spin systems, similar to the physics of Ising optimization. The CBO method, which searches the coupled configuration space, has shown superior performance in identifying optimal block removal configurations, even in hybrid models with unevenly distributed redundancy, outperforming methods like block influence.

Heretic, a project from heretic-project.org, has developed a method for fully automatic censorship removal in language models.

AX leverages agentic runtime research from Google DeepMind and relies on Agent Substrate, offering agentic abstractions and generative runtime components.

The M5 Ultra Mac Studio with 256 GB of RAM is reviewed as a dream machine for local AI agents. The author tested various cloud providers like Inco, Cerebras, Fireworks, and Baseten for AI tasks, noting their high performance (e.g., Kimi K3 at 300 TPS, Qwen3.8-27B at 1,800 TPS) but also their cost and data privacy concerns. The M5 Ultra Mac Studio allows for local execution of AI agents using Open Minis and Apple CLIs, ensuring data remains on the user's device.

The article "The Claude Delusion" from pluralistic.net discusses the challenges in understanding intentionality in AI, particularly for those unfamiliar with the intricacies of hacking. It highlights the difficulty in grasping the concept of "hacking without hackers," suggesting that many people assume intentionality behind any observed task, even when performed by AI. This perspective is presented as a significant barrier to what the author terms "AI atheism."

Meta's AI assistant, Muse, was blocked from Amazon.com, with users receiving an error message stating that "Continued access by an unauthorized AI agent violates Amazon’s Conditions of Use." This move by Amazon might stem from concerns about potential issues with agentic commerce, such as Muse making incorrect orders, which Amazon would then have to resolve with both customers and vendors. Despite Muse's relatively low hallucination rates, Amazon may prefer to wait for further AI model improvements before fully embracing agent-driven commerce.

Amazon has blocked Meta’s Muse AI agent, marking its latest effort to prevent rival agentic AI services from impacting its retail business. This follows a similar lawsuit against Perplexity in November last year, where a judge sided with Perplexity in August. Additionally, Amazon has been omitting specific item names and product images from confirmation emails since July to limit data mining by external AI services.
