Why it matters
GitHub is reframing its platform around orchestrating fleets of agents to produce completed work, which affects how teams using Copilot and Actions will plan, review and ship.
Key takeaways · AI-distilled
GitHub says Copilot Fusion decides how to run a task across one or more models based on its reasoning, coding, debugging and tool-use needs. On the Artificial Analysis Coding AI agentAn AI system that doesn't just answer once but works toward a goal in a loop — taking actions, reading the results, and deciding what to do next.Full definition → Index, Fusion Max scored within two points of Opus 5.5 Max at half the cost and 40% less time.
GitHub Enterprise customers can now use every Copilot feature, including the Copilot app, code review and automations, without a separate Copilot subscription, paying per AI credit used. It is sold through GitHub Sales now, with self-serve to follow.
Copilot automations run AI workflows in a repo on demand, on events or on a schedule, for jobs such as issue triage and code review, and can now propose improvements to themselves from their outcomes for a human to approve.
GitHub says it added 4 million CPU cores, 160 PB of fast storage and 50 Tb/s of network capacity this year to absorb agent load, plans a multi-region Azure move by early next year, and is rebuilding Git to decouple storage from compute.
