What is new

On April 23, 2026 OpenAI announced GPT-5.5, a new generation of its flagship model. Highlights:

  • Better coding — higher SWE-bench scores, improved multi-file refactoring
  • Computer use — the model controls GUI and browser more reliably and finishes tasks
  • Deep research — capability to autonomously run long research tasks
  • Workspace agents — admin role-based controls, free until May 6, 2026

Availability

The model is rolling out to Plus, Pro, Business and Enterprise plans in ChatGPT and Codex.

Why it matters

GPT-5.5 is a step toward a so-called “super-app” a single interface combining chat, code and browsing. For dev teams it means less context switching and the ability to delegate larger multi-step tasks.

My take

For me, this is a signal that agentic workflows are graduating from research preview to production. Clients who were waiting for “grown-up” tooling now have the green light.
