GPT-5.4 Now Available in GitHub Copilot OpenAI’s latest agentic coding model, GPT-5.4, is now being rolled out in GitHub Copilot. Early testing of the model’s real-world capabilities in software development has shown it achieving higher success rates compared to previous versions. The model demonstrates improved logical reasoning and task execution, particularly in handling complex, multi-step processes that require the use of external tools. The update is available to GitHub Copilot users on Pro, Pro+, Business, and Enterprise plans. Users can select the GPT-5.4 model through the model picker within the Copilot interface. While the model is accessible across all supported versions, OpenAI recommends upgrading to the most recent version of each product to ensure optimal performance with prompting and model parameters. For Copilot Enterprise and Copilot Business plan administrators, the GPT-5.4 model must be enabled through the Copilot settings by applying the appropriate policy. Detailed information about the available models in GitHub Copilot can be found in the official documentation, which also provides guidance on getting started with the platform. Users are encouraged to join the GitHub Community to share feedback and insights about their experiences with GPT-5.4. The release marks a significant step in enhancing the capabilities of AI-driven coding tools, offering developers more efficient and reliable assistance in their workflows.#software_development #github_copilot #openai #gpt_5_4 #github_community
