How LLMs work for Web Devs: GPT in 600 lines of Vanilla JS - Ishan Anand

Jul 13, 2025 · 1:41:34

Ishan Anand shows that GPT-2 small implemented in 600 lines of vanilla JavaScript makes LLMs understandable for web developers without ML backgrounds. He explains tokenization via byte-pair encoding, 768-dimensional embeddings representing semantic meaning via co-occurrence, and the Transformer's attention mechanism that lets tokens share context. The multi-layer perceptron learns next-token prediction through backpropagation, while the language head converts embeddings to token probabilities using softmax. Anand demonstrates each step—tokenization, embedding lookup, positional encoding, attention, MLP, and output—in a browser debugger, and notes that GPT-2's architecture underpins ChatGPT, with innovations like scale, supervised fine-tuning, and RLHF. The workshop provides an intuitive mental model of Transformers, turning perceived AI magic into understandable machinery.

Mastering Engineering Flow with Windsurf - Eashan Sinha, Windsurf

Jun 27, 2025 · 15:20

Eashan Sinha, a Deployed Engineer at Windsurf, explains how engineering teams can master agentic IDEs using Windsurf's Cascade agent. He argues that developers should treat AI as a teammate rather than a tool to abuse, emphasizing Windsurf's flow awareness—tracking user actions, edits, and terminal commands to infer intent. Sinha details Windsurf's evolution from copilots to agents, combining collaborative chat with autonomous tool calling, and introduces features like state-of-the-art context engine, workflows for deterministic steps, rules, memories, and simultaneous Cascades. He provides a practical four-step framework—explore, plan, build, test—for maximizing agentic flow, including using planning files, checkboxes, and automated test generation. The episode delivers a concrete guide to integrating AI into development without sacrificing quality, recorded at the AI Engineer World's Fair in San Francisco.

Harnessing the Power of LLMs Locally: Mithun Hunsur

Nov 22, 2023 · 17:09

Mithun Hunsur presents llm.rs, a Rust library for running large language models locally, arguing it gives developers ownership, lower latency, and privacy compared to cloud APIs. He explains how quantization makes inference viable on consumer hardware, and shows that llm.rs supports architectures like LLaMA and Falcon through a unified interface. Practical code examples demonstrate customization, and community projects like LocalAI and LLMchain illustrate real-world use. Hunsur shares his own date-extraction pipeline, fine-tuning a small model with GPT-3 data to replace expensive cloud calls. He also cautions about hardware requirements, trade-offs between speed and quality, and ecosystem churn from rapid innovation.
