AI Agent Architecture: Trust, Not Accuracy

2025-09-05

This post dissects the architecture of AI agents, arguing that user experience trumps raw accuracy. Using a customer support agent as an example, it outlines four architectural layers: memory (session, customer, behavioral, contextual), connectivity (system integrations), capabilities (skill depth), and trust (confidence scores, reasoning transparency, graceful handoffs). Four architectural approaches are compared: single agent, router + skills, predefined workflows, and multi-agent collaboration. The author recommends starting simple and adding complexity only when needed. Counterintuitively, users trust agents more when they're honest about their limitations, not when they're always right.

Random Walks in 10 Dimensions: Defying Intuition in High-Dimensional Spaces

2025-09-04

High-dimensional physics is the norm in modern dynamics, from string theory's ten dimensions to complex systems. However, high dimensions present the 'curse of dimensionality': visualization is impossible, overfitting is rampant, and intuition fails. This article uses a 10-dimensional random walk to illustrate high-dimensional space characteristics. In high dimensions, mountain ridges are far more common than peaks, profoundly impacting evolution, complex systems, and machine learning. Random walks efficiently explore high-dimensional spaces, even maximally rough landscapes, potentially traversing the entire space. This helps understand the evolution of complex structures in life and how to avoid local minima in deep learning.

Building Effective AI Agent Evaluation: From E2E Tests to N-1 Evaluations

2025-09-04

This article explores building efficient AI agent evaluation systems. The author stresses that while models constantly improve, evaluation remains crucial. It advocates starting with end-to-end (E2E) evaluations, defining success criteria and outputting simple yes/no results to quickly identify problems, refine prompts, and compare different model performances. Next, "N-1" evaluations, simulating previous user interactions, can directly pinpoint issues, but require maintaining updated "N-1" interactions. Checkpoints within prompts are also suggested to verify LLM adherence to desired conversation patterns. Finally, the author notes that external tools simplify setup, but custom evaluations tailored to the specific use case are still necessary.

MIT Study: ChatGPT Causes Cognitive Decline in Essay Writing

2025-09-03

An MIT study reveals that using ChatGPT for essay writing leads to measurable cognitive harm. EEG scans showed weakened neural connectivity, impaired memory, and reduced sense of authorship in students who repeatedly used the AI. Even with high-scoring essays, the brain's engagement was significantly reduced. The study found that LLMs cause under-engagement of critical brain networks, and even after ceasing AI use, cognitive function doesn't fully recover. This 'cognitive offloading' leads to long-term impairment of learning and creativity.

World Models: The Illusion and Reality of AGI

2025-09-03

The latest pursuit in AI research, especially in AGI labs, is the creation of a "world model" – a simplified representation of the environment within an AI system, like a computational snow globe. Leading figures like Yann LeCun, Demis Hassabis, and Yoshua Bengio believe world models are crucial for truly intelligent, scientific, and safe AI. However, the specifics of world models are debated: are they innate or learned? How do we detect their presence? The article traces the concept's history, revealing that current generative AI may rely not on complete world models, but on numerous disconnected heuristics. While effective for specific tasks, these lack robustness. Building complete world models remains crucial, promising solutions to AI hallucinations, improved reasoning, and greater interpretability, ultimately driving progress towards AGI.

LLMs: Lossy Encyclopedias

2025-09-02

Large language models (LLMs) are like lossy encyclopedias; they contain a vast amount of information, but this information is compressed, leading to data loss. The key is discerning which questions LLMs can answer effectively versus those where the lossiness significantly impacts accuracy. For example, asking an LLM to create a Zephyr project skeleton with specific configurations is a 'lossless' question requiring precise details, which LLMs struggle with. The solution is to provide a correct example, allowing the LLM to operate on existing facts rather than relying on potentially missing details within its knowledge base.

SGLang: An Open-Source Implementation Matching DeepSeek LLM's Inference Performance

2025-08-29

DeepSeek, a popular open-source large language model (LLM), boasts impressive performance. However, its massive size and unique architecture (using Multi-head Latent Attention and Mixture of Experts) demand a sophisticated system for efficient large-scale serving. This blog details how we achieved near-parity with DeepSeek's inference system performance using SGLang. Our implementation, running on 12 nodes (each with 8 H100 GPUs) in the Atlas Cloud, leverages prefill-decode disaggregation and large-scale expert parallelism (EP), reaching 52.3k input tokens/second and 22.3k output tokens/second per node for 2000-token input sequences. This is, to our knowledge, the first open-source implementation to nearly match DeepSeek's reported throughput at scale, at roughly one-fifth the cost of the official DeepSeek Chat API.
