GitHub announced Wednesday that it is expanding its platform to handle the enormous demand from AI agents. According to The Register, the company made the announcement during a conference in San Francisco.
In September 2026, GitHub recorded 7.4 billion code commits, five times as many as in the same month last year. The increase is driven by developers using AI agents to generate ever-larger amounts of code. GitHub stated that it was surprised by this development, which led to a series of outages and service availability issues.
AI-driven code commits began to cause problems last December and led to issues in the months that followed. On May 7, the site’s 90-day availability hit a low of approximately 84 percent. This is evident from reconstructed data from GitHub’s status page.
Company executives subsequently apologized and announced measures to improve availability. GitHub has therefore scheduled an infrastructure expansion to add four million CPU cores and 160 petabytes of high-speed storage capacity. This is separate from the additional computing capacity for GitHub Actions, the platform that handles the company’s continuous integration and continuous delivery (CI/CD).
Separating computing power and storage
The code-hosting company, owned by Microsoft, says it is redesigning its architecture. The goal is to separate computing power from storage. This would enable a 35-fold increase in throughput.
During the conference, GitHub also announced the general availability of Copilot Fusion. This is the company’s model routing service, which was previously shown in preview under the name HydraFusion. The idea is that by routing requests to different models, GitHub can improve task success rates. It can also reduce the costs associated with token usage.
Copilot Fusion evaluates what a task requires in terms of reasoning, code generation, debugging, and tool usage. Copilot Fusion then determines how this task should be executed using one or more models. In the Artificial Analysis Coding Agent Index, Fusion Max finished less than two points behind Opus 5.5 Max. Meanwhile, costs were half as high, and it completed tasks 40 percent faster.
More features via the Copilot app
GitHub is also adding more features to its Copilot app, including Copilot Projects, for coordinating parallel work. Copilot Connectors, designed to simplify Copilot’s connection to MCP servers, is also being added.
And in what appears to be an effort to encourage the use of Copilot in the workplace, GitHub is expanding access to Copilot to all GitHub Enterprise users. They don’t need to make any additional per-user purchases. Customers will still be billed for the tokens they use.
