GPT-5.4 is generally available in GitHub Copilot
GPT-5.4, OpenAI’s latest agentic coding model, is now rolling out in GitHub Copilot. In our early testing of real-world, agentic, and software development capabilities, GPT-5.4 consistently hits new rates of success. It also shows enhanced logical reasoning and task execution for intricate, multi-step, tool-dependent processes.
