Handwired: Turn Your Regular JavaScript Code into a Neural Net

Handwired is a tool that transforms standard JavaScript code into a neural network without requiring training, making it fully differentiable and runnable in a browser without GPU support. For example, a simple conditional statement like `const result = a > 4 ? 10 : 12` can be converted into a neural network representation using ReLU activation functions. The website offers demos such as a mini operating system written in JavaScript, a learned gallery for real-time training of compiled program weights, and a tool for searching 100,000 JSON documents using WebGPU kernels for massive parallelism.

Code Is Cheap Now. That's Why It Matters.

Stephen Margheim argues that despite AI's ability to generate code, the fundamental skills of programming remain crucial. With AI making code easier and faster to produce and modify, codebases become more malleable, allowing improvements and refactoring to be applied universally and instantly. This dynamic increases the importance of well-designed, consistent abstractions because AI coding agents rely heavily on existing code to generate new solutions. Thus, the real value for programmers is in crafting and recognizing better architectures and abstractions, which have greater impact and leverage in the age of AI-assisted coding.

Jev Ultrafast is a browser agent designed to execute tasks based on natural language goals by dynamically selecting operations and elements, utilizing a small language model (LLM) for text generation only when necessary. This approach aims to reduce latency associated with static tool definitions in traditional browser agents. For example, it can perform a flight search on Google Flights in approximately 7.1 seconds, including text generation and loading times. The agent operates by observing the current page, indexing elements, and choosing appropriate operations to achieve the user's goal efficiently.

Probably: A Programming Language for LLM Workflows

Probably is a programming language designed for large language model (LLM) workflows, emphasizing probabilistic decision-making and uncertainty handling. It integrates with Jev, a typesafe AI platform, to manage judgments and probabilities. Key features include variable declarations, input/output handling, and constructs like `feels` for probabilistic conditionals, `match` for branching based on descriptions, and `llm` for interacting with language models. The language is tailored for tasks such as drafting email responses, where understanding and managing uncertainty is crucial.
