## Post

We're redefining the SDLC for the agentic era.

Lots of GitHub updates this morning at Universe:

• GitHub Copilot Fusion delivers frontier-level quality, 40% faster and at up to 77% lower cost

• Our unified Copilot harness is now in Foundry, a managed service for building long-running agents that reason, use tools, and get work done

• Copilot Projects gives you an orchestration loop to build with multiple agents across repos

And we’re expanding capacity and strengthening GitHub’s architecture to make the home of agentic development more resilient.
