GitHub said on April 3, 2026 that developers can now build with the GitHub Copilot SDK in public preview. GitHub’s changelog says the SDK exposes the same agent runtime behind Copilot cloud agent and Copilot CLI, with support for custom tools, streaming, permissions, and BYOK across five languages.
GitHub said in a March 31, 2026 X post that programmable execution is becoming the interface for AI applications, linking to its March 10 Copilot SDK blog post. GitHub says the SDK exposes production-tested planning and execution, supports MCP-grounded context, and lets teams embed agentic workflows directly inside products.
On March 13, 2026, GitHub showed a Copilot SDK and Remotion demo that turns a WhatsApp message into a promo video in about five minutes. GitHub’s official SDK announcement describes the stack as a programmable layer that can plan, invoke tools, edit files, and run commands inside other applications.
