Continuing the comparative review of GitHub’s Octoverse reports, let us look at developer productivity.

AI’s effect on productivity and development processes

  • In 2023, most developers believed AI tools would improve teamwork, satisfaction and productivity. Among respondents, 81% thought AI coding tools would make teams more cohesive and collaboration easier.
  • In 2024, Octoverse presented concrete findings on Copilot. An earlier study reported productivity gains of up to 55% on tasks performed with an AI assistant. The report itself identified a correlation: regular Copilot users were more active on GitHub. Among daily active developers, visible activity such as commits and pull requests was roughly 12–15% higher than for peers without AI. I read this as quantitative and subjective support for AI saving time and helping engineers complete more work per unit of time.
  • In 2025, AI’s influence appeared in delivery and remediation speed as well as code volume. GitHub reported that Copilot Autofix’s generated fixes let developers resolve some vulnerabilities, including SQL injection and XSS, 3–12 times faster than manual fixes: minutes rather than hours. Automated dependency updates through Dependabot also became normal, with more generated PRs merged and vulnerabilities closed sooner. The year saw record activity: more than 43 million PRs merged per month and almost 520 million over the year. The review links much of this scale to AI-assisted efficiency gains.

Changes in language popularity associated with AI Octoverse records substantial shifts in language rankings, influenced in part by AI:

  • In 2023, JavaScript remained GitHub’s most popular language. TypeScript gained rapidly, overtaking Java for 3rd place in open-source use, with its community growing 37% in a year.
  • In 2024, Python overtook JavaScript. The report connects this to the boom in data analysis and machine learning: Python’s strength in AI/ML, scientific computing and education helped it reach the top. Jupyter Notebook popularity also rose 92%, reflecting the arrival of data specialists and researchers.
  • In 2025, TypeScript became No. 1 by developer count for the first time, overtaking Python and JavaScript. The report calls this the biggest ranking change in a decade. It connects the shift to AI and agents influencing technology choices: typed languages such as TypeScript support more reliable suggestions and generated code, particularly in production systems. Developers increasingly favour it because strict typing improves completion and generation. Modern frontend frameworks, including React and Next.js, also tend to offer TypeScript by default. Although TypeScript moved into first place, the combined JavaScript/TypeScript ecosystem still generates more activity than Python alone. Python remains the clear leader in AI, data analysis and scientific research, all of which continued growing on GitHub.
