GitHub Copilot now supports OpenAI’s latest coding model, GPT-5.4, designed for complex development tasks and advanced problem-solving.
GPT 5.4 launched shortly after Anthropic released Cloud Opus 4.6. Both are available to Co-Pilot subscribers on the Pro, Pro+, Business, and Enterprise plans.
A major difference: context size GPT 5.4 supports up to 400 tokens, while Cloud OPS 4.6 supports up to 192k. This allows Cloud OPS 4.6 to handle larger codebases more efficiently.
Open UI’s new fast version, GPT‑5.4, is now available in GitHub Co‑Pilot. Early tests show it’s their best mini model so far. It responds quickly, explores codebases well, and works especially well with GREP‑style tools.
Keep in mind this model starts with a 0.33x premium request multiplier, but pricing may change.
Availability in GitHub Copilot
GPT-5.4 Mini is available to Copilot Pro, Pro +, Business, and Enterprise users. You will be able to select the model in the Model Picker in Visual Studio Code, and later in all modes: chat, ask, edit, and agent.
- Visual Studio versions and later in all modes: agent, ask.
- JetBrains versions and later in all models: ask, edit, agent
- Xcode versions and later in all models: ask, agent
- Eclipse versions and later in all modes: ask, agent.
- Github.com
- GitHub, Mobile, iOS, and Android.
- GitHub, CLI.
Although GPT-5.4 Mini is available in all the versions listed above, it works best with the latest versions. We recommend upgrading to get the best experience.
Enabling access.
For administrative and business plans, administrators must enable the GPT-5.4 Mini policy in Copilot settings. After that, users in the organization will see GPT-5.4 Mini in the model picker in Visual Studio.
If you are using your own API key, go to Manage Models in the Picker, select GPT-5.4 Mini, and enter your API key when asked.

GitHub Co‑Pilot with GPT 5.4 is compatible with numerous development environments, including Visual Studio Code, Visual Pro, JetBrains IDEs, Xcode, Eclipse, GitHub.com, GitHub Mobile, and GitHub CLI.
GitHub Copilot is Microsoft’s AI-powered coding assistant. It uses large language models (LLMs) within code editors to suggest code, explain snippets, and help with common programming tasks directly as you work.
GitHub Copilot functions as an autocomplete tool for coding. It analyzes your code and suggests the next line or even entire functions. Some developers use it to build complete applications with minimal human input, a trend known as “wide coding,” rather than debating or explaining the code, and focus on presenting these developments, as AI controversy can be exhausting regardless of personal opinions.
AI coding tools are evolving rapidly, and they’re becoming part of developers’ work. Whether we like it or not, some people use them all the time while others stick to traditional coding.
GitHub is making a major leap by releasing OpenAI 5.4 to all 12 Copilot users, introducing powerful computer control and a 1 million–token context window.
What Sets GPT 5.4 Apart
This update is more than a small step forward. GPT 5.4 introduces autonomous computer control, enabling the model to simulate mouse and keyboard actions across different applications without human intervention. Now, Copilot can manage multi-step work rules that are used to require manual switching between tools.
The 1 million-token context vendor lets developers include entire codebases in conversations. GitHub internal tests show that GPT 5.4 is achieving new levels of success on real-world development tasks, especially those with complex multi-step processes.
OpenAI’s benchmarks show GPT-5.4 Mini has 33% fewer factual errors than GPT-5.2 and outperformed professionals in 83% of benchmarked tasks, up from 70.9% in the prior version.
How To Access GPT 5.4
Individual Pro and Pro+ users get immediate access via the model Pika. Enterprise and business administrators need to manually integrate GPT-5.4 in their corporate policy settings before team members can use it.
GitHub recommends upgrading to the latest IDE versions to ensure full compatibility and access to prompt tuning capabilities. Using outdated versions may limit your experience: the model’s interface may appear, while newer features do not function as intended.
Looking At The Bigger Picture.
GPT-5.4 Mini launches with two versions: Thinking, optimized for step-by-step reasoning, and Pro Design, for enterprise production workloads. The Thinking version allows users to outline their reasoning at the start and provide input during a response, offering benefits for debugging complex logic chains.
OpenAI will retire GPT 5.2 on June 5, 2026, giving teams about 3 months to update their procedures. Developers who rely on Copilot agents should start testing GPT 5.4 now to identify any prompt adjustments needed before it is rolled out. the sweet
