GitHub has recently announced that its code completion and programming tool, Copilot, will now support multiple model selections. Developers will have the option to choose models from Anthropic, Google, and OpenAI when using GitHub Copilot. Additionally, during the GitHub Universe conference, GitHub unveiled Spark, an AI tool designed for building web applications, and introduced updates to GitHub Copilot's functionalities in VS Code, Xcode, and other platforms.

GitHub Copilot users on the web and VS Code will be able to select the Claude 3.5 model, while the Gemini 1.5 Pro model is set to launch in the coming weeks. Additionally, OpenAI's GPT-4o, o1-preview, and o1-mini models will soon be available within GitHub Copilot. Developers can switch between models during interactions with Copilot Chat to identify the best-suited model for specific tasks.

GitHub CEO Thomas Dohmke stated that no single model can cater to every scenario, and developers desire the ability to select the model that best fits their work. Clearly, the next phase of AI code generation will be shaped not only by multi-model capabilities but also by the option to choose between different models.

Since its initial launch in 2021, GitHub Copilot has attracted over one million paying users, as announced by GitHub last week. Copilot marks Microsoft's first major achievement following its initial $1 billion investment in OpenAI. It remains unclear whether Microsoft will adopt GitHub's multi-model approach and open its own Copilot AI assistant to models from competitors like Google and Anthropic.

GitHub also introduced Spark, an AI tool that utilizes natural language to simplify the construction of web applications. Using initial prompts, Spark generates real-time previews of web applications with models from OpenAI and Anthropic, allowing users to compare different versions as they make changes. Spark enables experienced developers to interact directly with the code, while beginners can fully create web applications using natural language.

Once created, applications can run on desktops, tablets, or mobile devices and can be shared with others, facilitating further creation based on Spark applications. Spark is part of GitHub's initiative to reach a target of one billion developers.

At the GitHub Universe conference, GitHub also announced additional updates to Copilot. GitHub Copilot in VS Code will introduce multi-file editing capabilities on November 1st, allowing users to edit multiple files simultaneously using Copilot Chat. Copilot Extensions are slated for release in early 2025, GitHub Copilot for Xcode has entered public preview, and Copilot now features new code review functionalities.
