Microsoft's code-assisting tool GitHub Copilot once again demonstrated its impressive response speed. Just hours after OpenAI officially released its latest flagship large model, GPT-5.4, GitHub announced that it had completed integration, offering global developers intelligent programming support based on this cutting-edge model.

GitHub official stated that internal early test data showed GPT-5.4 performed exceptionally well in "agentic" software development scenarios, with a significant improvement in task success rate compared to the previous generation. The model not only inherits the professionalism of the Codex series in code generation, but also shows stronger stability in complex multi-step logical reasoning.

Core capability improvements of GPT-5.4 in Copilot include:

  • Multi-step Task Execution: When handling tasks that require calling multiple tools or complex workflows, it shows more rigorous logic and higher execution accuracy.

  • Deep Web Retrieval: Enhanced real-time information access capabilities, enabling more accurate solutions to programming problems involving the latest technical documentation.

  • Computer Operation Optimization: Demonstrates greater efficiency when performing low-level tasks such as automated environment configuration and file operations.

Currently, GPT-5.4 is available for all levels of Copilot subscribers, including Copilot Pro, Business, and Enterprise. Developers just need to update Visual Studio Code to version v1.104.1 or higher, or update Visual Studio to version 17.14.19 or higher, to call this model in chat, edit, and agent modes. In addition, mainstream development environments such as JetBrains IDE, Xcode, and Eclipse have also been synchronized with support.

For enterprise users, GitHub reminds organizational administrators to manually enable the GPT-5.4 usage policy in the Copilot management console in order to unlock the relevant access permissions for team members.
