Multiple new models are now generally available in GitHub Copilot

Anthropic Claude 3.7 Sonnet, Claude 3.5 Sonnet, OpenAI o3-mini, and Google Gemini Flash 2.0 are now generally available in GitHub Copilot. With this change, these models are promoted from preview release terms to generally available release terms. This extends indemnification for IP infringement to code generated using these models in Copilot Chat and agent mode.

  • Claude 3.7 Sonnet, Anthropic’s most advanced model to date, excels in development tasks that require structured reasoning across large or complex codebases.
  • Claude 3.5 Sonnet remains a good choice for everyday coding support.
  • OpenAI o3-mini is a fast, cost-effective reasoning model designed to deliver coding performance while maintaining lower latency and resource usage.
  • Gemini 2.0 Flash is Google’s model optimized for fast responses and multimodal interactions.

The official open source GitHub MCP Server

Today we’re releasing a new open source, official, local GitHub MCP Server. We’ve worked with Anthropic to rewrite their reference server in Go and improve its usability. The new server contains 100% of the old server’s functionality plus the ability to customize tool descriptions, support for code scanning and a new get_me function that improves the natural language user experience when asking the LLM things like: “Show me my private repos.”

To get started, visit the repository and learn how to set up the GitHub MCP Server, which is now supported natively in VS Code.

Model Context Protocol (MCP) is an AI tool calling standard that has been rapidly gaining adoption over the past few months. MCP tools give LLMs a standardized way to call functions, look up data, and interact with the world. Anthropic created the protocol and built the first GitHub MCP server, which grew to be one of the most popular MCP servers in the expanding ecosystem. We are excited to take ownership of the server and continue its development.
