Practical guides from our trainers — plus how to fund your upskilling with WSQ funding and SkillsFuture Credit.
OpenAI launched GPT-6 Astra on 3 September 2026 and Greg Brockman closed the briefing with "Welcome to the AGI era". Here is what the benchmarks really say, where the caveats are, and the concrete agentic AI skills that matter now that models can drive a computer end to end.
Both are agentic coding tools. Both ship a desktop app, an IDE extension, a CLI and a web surface. The real difference is where each one puts its centre of gravity: Codex is built to delegate work to, Claude Code is built to work alongside. Here is the honest comparison — context windows, token efficiency, multi-agent coordination, price — and which to learn first.
An n8n workflow is just a JSON file. That means you can describe what you want to an AI coding agent like Claude Code or OpenAI Codex, have it generate the whole workflow, and import it in one paste — no dragging, no mis-typed expressions, no silently broken node connections. Here is the exact method, the prompt template, and how to self-host n8n on a cheap Hostinger VPS so you can run it all unlimited.
Building an AI demo is easy. Building an AI application people can trust is a different discipline. Explore the six connected skill areas that turn unpredictable model behaviour into useful, testable and production-ready software.
