Coding with GPT-5.4 in VS Code

OpenAI officially released GPT-5.4 on March 5, 2026. This is a "frontier model" that merges advanced reasoning with native computer-use capabilities.

  • Agentic Workflows: Unlike previous models, GPT-5.4 can natively click, type, and navigate desktop environments, scoring 75% on the OSWorld-Verified benchmark (surpassing the human baseline of 72.4%).
  • Professional Power: It is specifically engineered for "real work"—financial modeling (87.5% accuracy), complex spreadsheet management, and presentation editing.


GitHub has immediately integrated GPT-5.4 into Copilot for Visual Studio Code (v1.104.1+).

  • Multi-file Edits: It can now orchestrate coordinated refactorings across entire repositories, not just single files.
  • Agent Mode: Developers can hand off entire tasks to background agents that persist state across sessions and drive build/test interactions.


We have seen the evolution of dev tools from manual systems analysis to AI-assisted coding, and this is the milestone we've been waiting for.

This isn't just a minor patch. It's the jump to Agentic Coding!

If you're managing dev teams or teaching Computer Science, it's time to update to VS Code v1.104.1+ and enable the GPT-5.4 policy in your Copilot settings. The future of software development isn't just about writing code; it's about directing agents.
