OpenAI has unveiled GPT-5.3-Codex, a significantly upgraded coding model, boasting improved performance and expanded capabilities across the entire software development lifecycle, according to multiple reports. The new model, which played a crucial role in its own creation, promises a 25% speed increase and is designed to be a comprehensive software development tool, encompassing debugging, deployment, and monitoring. While API access is not yet available, the announcement marks a notable advancement in AI-powered coding.
GPT-5.3-Codex, released by OpenAI, outperforms its predecessors in several benchmarks, according to Ars Technica. The model is accessible through various interfaces, including a macOS desktop app. The development highlights OpenAI's ambition to expand the utility of its models beyond code generation.
In related news, the intersection of classic hardware and modern technology continues to evolve. Analogue is releasing new, limited-edition transparent color options for its 4K N64 console, inspired by unreleased Nintendo 64 prototypes, as reported by The Verge. These new colors, including "extreme green" and "atomic purple," will be available for purchase starting February 9th, offering a nostalgic aesthetic for retro gaming enthusiasts.
Meanwhile, the maker community continues to explore innovative uses for microcontrollers. One project involves turning an ESP32-S3 microcontroller into a tiny instant-on PC with its own shell, editor, compiler, and online apps installer, as detailed on Hacker News. This demo uses BreezyBox, a mini-shell ESP-IDF component, offering a glimpse into a "cyberdeck" style crafting project.
Another project highlighted on Hacker News showcases r3forth, a minimalist programming language and environment inspired by ColorForth and the Forth philosophy. Designed to be a complete, self-contained system, r3forth balances extreme minimalism with practical creative power. The r3 environment is built for simplicity and speed, with a core VM written in C.
