GitHub Octoverse 2026: Code Commits and Pull Requests Surge as AI Agents Shape Development

Record Development Activity Driven by AI Integration

GitHub has released its annual Octoverse report, revealing unprecedented development activity over the past 12 months. Developers pushed code to the platform 17.9 billion times, eclipsing the combined totals for 2024 and 2025. Total commits across all public and private repositories reached 34.3 billion, while merged pull requests climbed to 1.3 billion, averaging 3.5 million per day.

The surge in volume coincided with the widespread adoption of AI coding agents. According to platform telemetry, the nature of software development shifted significantly as agents moved from experimental tools to daily collaborators. By September 2026, over 40% of pull requests started with an agent's first draft, up from 17% in March. Repositories equipped with agent configuration files logged an average of eight times as many commits as new repositories without them.

Diversification Across Industries and Models

The report highlights growth not just in software volume, but across diverse economic sectors. Using industry classification systems to analyze public repositories, GitHub noted substantial expansions in fields including mining, construction, health care, and agriculture since 2022. Projects range from industrial heat-reuse toolkits to automated tissue sample analysis for medical research.

Developer adoption of AI models also showed high flexibility. Among GitHub Copilot users who manually selected models in September 2026, 61% used more than one model across their sessions. Requests were distributed across general-purpose, deep-reasoning, and fast-lightweight models. Furthermore, 63% of paying Copilot developers utilized auto model selection features to delegate model choice based on specific tasks.

Practical Implications and Verification

What Is Confirmed

• Developers pushed code to GitHub 17.9 billion times over the measured 12-month period.
• Over 40% of pull requests began with an agent draft by September 2026.
• TypeScript remained the most-used language by contributors, followed by Python and JavaScript, with Rust showing the fastest percentage growth among top languages.
• Global developer communities in the United States and India each added more than 10 million users over the year.

What Remains Unknown

• The long-term trajectory of developer growth past 2031, as predictive models project widely divergent scenarios ranging from doubling to extreme tripling of user counts.
• The exact ceiling of automated agent integration, as telemetry captures detected signals rather than total usage.
