URAX Neural Lab is a deterministic browser-based laboratory for building, training, evaluating, and saving small feed-forward neural-network experiments. The application runs entirely in the browser, uses Web Worker training, supports CSV and complete.urax.json projects, and includes English and Czech localization. Built for OpenAI Build Week 2026 using Codex and GPT-5.6.
Codex Audit analyzes any code diff or AI coding-agent session and instantly generates a plain-English risk report, flagging hardcoded secrets, risky dependency changes, deleted tests, and security-sensitive edits before they get merged. Instead of manually re-reading every line an AI agent changes, a reviewer gets a clear risk score, a decision log explaining why each change was likely made, and a prioritized checklist of what to double-check, all generated by GPT-5.6. The entire project was bui
Doro is a handmade desktop focus companion built with Codex and GPT-5.6 for OpenAI Build Week 2026. Instead of feeling like another productivity dashboard, Doro works alongside you: waiting when you are idle, moving while you focus, resting when you pause, and celebrating when you finish. Features include: • Custom activities and focus durations • Expressive idle, running, paused, and finished states • Completed and interrupted session tracking • Daily, seven-day, and all-time focus his
Type in a child's real spelling mistakes. GPT-5.6 detects the perception patterns behind them and composes a personalized 20-page training workbook from 123 worksheet generators. Built with Codex during OpenAI Build Week 2026. Try it: https://legasthenie.me/generator/ki-fehleranalyse Code: https://github.com/dyslexics/legasthenie-me
15Loop is an AI vocabulary learning app that finds the missing connection between spelling, sound, meaning, and recall. Built during OpenAI Build Week with Codex and GPT-5.6, 15Loop asks learners to recognise a word, hear it, understand it in context, and recall it independently. GPT-5.6 evaluates learner-created sentences and gives feedback in Korean and English. The next review focuses on the connection that needs more work.

Project built with Codex and GPT-5.6 Sol.
Do you think there could exist a situation in the market where either Anthropic or OpenAI will offer chinese models for their clients?
The core idea is to keep the LLM frozen and train everything around it (e.g. prompts, context management, tools, repair loop). The harness is one editable Python file. In each epoch, an agent proposes one diff, the diff is measured against baseline on a task panel, and a strict Pareto criterion decides whether the commit gets promoted. optimizer.step() is literally a git fast-forward or stored as git ref if the commit was not promoted.Evaluation results show transfer learning (e.g. harness train
After 2 months of hard work, Cycling through three 20x Codex Subs, three 20x Claude Code subs, and using over 90 billion tokens,I have finally submitted a working Native App (Cross-Platform, but mainly MacOS and Windows Supported, Linux is kind of untested as I don't have a linux device).Main takeaway is that: its a Wrapper for your AI Agents that allow you to use multiple terminals simultaneously, see sessions history, connect to the web, and control your AI Agents via the cloud remotely
I use Pi coding agent with OpenAI GPT-5.6 Sol but have been finding that GPT-5.6 is slower than Claude Code. Do you use any other model like one of the hosted OSS ones?
An OpenAI-compatible API generator backed by Cloudflare Workers AI — chat, speech, vision, embeddings — deployed to your account in one click and with a testing dashboard. No login, just need a Cloudflare account and a single-use CF token to deploy.I'm a big fan of testing the latest models deployed on Cloudflare, and the 10,000 "neuron" allotment per day is pretty generous.I built this to supplement a side project I've been working on for the last six months. https:/&#x
As Anthropic races toward a high-stakes IPO, China is stepping up its AI ambitions and positioning its cheaper models as a ...
By pushing for ever-tougher AI safety laws, Anthropic is drawing a distinction between its state lobbying strategy and OpenAI's campaign to streamline a set of rules across the country.
Anthropic's Claude Corps will pay $85,000 to 1,000 early-career professionals - apply now ...
You can't buy Anthropic yet, but these two companies are already cashing its multibillion-dollar AI checks -- and could be smart ways to invest before the IPO.
I'm currently traveling and relying on free wifi hotspots and 3G cellular. It's shocking to me how many apps are completely unusable on slow internet.<p>Back in the day, our test suites always included a "slow client internet" test to identify issues where there were too many round trips or unnecessarily large payloads.<p>What happened to that?<p>(ps. Props to OpenAI, Codex still works on slow internet. Claude won't even load its interface)
GPT-5.4 Thinking delivers deeper analysis than earlier ChatGPT models. It has strong reasoning, but it sometimes answers questions you didn't ask. Formatting and image generation lag behind the text ...
