Overview

In this episode, Dan Shipper sits down with Thomas Dohmke, CEO of GitHub, to explore the evolution of AI-powered coding tools, the launch of the GitHub Copilot agent, and the competitive landscape shaping how millions of developers worldwide work. The conversation digs into product decisions, the architecture and advantages of GitHub’s new agent-based workflows, and the future role of AI across all levels of software development.

Key Discussion Points & Insights

1. The Evolution of AI Coding Tools and Copilot

• GitHub's AI Journey: Copilot emerged before the mainstreaming of tools like ChatGPT, powered by advances in models like GPT-2 and GPT-3.
• Initial Concepts: Early ideas for Copilot included code-to-text (explanation), conversational chat, and code auto-completion.
  • Auto-completion was the first to find traction due to its immediate value to developer workflows.
  • Thomas:

    "We had these moments where we're like, holy shit, this actually works and can separate Python from JavaScript." (02:00)

• Ecosystem Explosion: The success of Copilot spawned a wave of new startups and tools, creating intense competition ("the AI coding arms race") from IDE extensions (Cursor, Windsurf), open-source tools, CI/CD platforms, and security tooling.
• Integration Philosophy: GitHub sees itself as a hub within this expanding ecosystem, aiming to seamlessly connect agents, enterprise features, and developer tools.

2. Competitive Landscape and Repositioning with Agents

• Changing Zeitgeist: While GitHub had early momentum, newer competitors have shaped the market narrative.
  • Dan:

    "When I think about the ecosystem of next generation AI coding... GitHub doesn't come up as much." (01:41)

• Staying Ahead:
  • Thomas:

    "Over the last year, it has clearly turned out to be that race between a Copilot, Cursor and Windsurf. We believe we still have the biggest user base across these three." (08:05)

  • Importance of continuous reinvention, rapid shipping (over 100 Copilot change logs in 2025 so far), and supporting developer choice.

3. GitHub Copilot Agents: What Sets Them Apart

• Integration with GitHub Actions:
  • Actions, GitHub’s CI/CD platform, provides a "compute layer" trusted by developers and enterprises.
  • Copilot agents run within familiar developer workflows, using Actions to create PRs, run tests, fix vulnerabilities, and even auto-review code.
  • Thomas:

    "We believe this integration of the agent in the same workflow that your team is already doing is incredibly powerful because you don't have to relearn how you're reviewing code." (14:53)

• Enterprise Security & Auditability:
  • Actions ensures code never leaves trusted boundaries; audit logs are integrated for compliance.
  • Agent session logs persist in the repo, just like human collaboration.
• UX & Collaboration:
  • Agents can be triggered from within the IDE or GitHub UI, creating seamless hand-offs similar to collaborating with human coworkers.

4. Customization, "Taste," and Developer Choice

• Supporting Multiple Models: GitHub Copilot supports OpenAI, Anthropic's Claude, Google Gemini, DeepSeek, and others. Developers can even bring their own API keys (openrouter, etc.).
  • Thomas:

    "Developers want choice in the same way that they want choice when they're picking the programming language and the open source library." (16:44)

• Custom Instructions:
  • Repositories can include custom prompt files, tailoring agent behavior (e.g., output language preferences).
• Internationalization:
  • Agents democratize access, enabling coding assistance in any major language, not just English.
  • Thomas:

    "We're democratizing access to computer technology... with these copilots being able to speak any human language, not just English." (18:44)

5. Product Decisions and Serving Different Developer Profiles

• Serving Both Enterprises and Individual Hackers:
  • Balance between the needs of massive enterprises and the rise of "AI-first" solo developers writing code almost entirely with agent assistance.
• Core Philosophy:
  • GitHub’s principle: "Put the developer first"—not just the enterprise or open source foundations.

    "Everybody at GitHub, not only the engineers... they all are using GitHub for everything." (22:04)

• The Expanding Definition of “Developer”:
  • Traditional code literacy still matters for complex projects, but AI agents and low-code tools are broadening who can build software.

    “What it means to be a developer is changing in certain ways.” (Dan, 23:44)

  • Yet, understanding code remains vital for business-critical or complex applications:

    "I don't believe in a world where you can create something like GitHub without knowing what the code actually does." (Thomas, 24:17)

6. Looking to the Future: AI, Agents, and Coding

• Predictions for the Next Year:
  • Agentic workflows will proliferate (coding, review, security, monitoring).
  • The "full stack builder" paradigm will emerge: small companies leveraging agents for every phase from design to deployment.
  • Legacy languages and traditional IDEs will persist; many developers will still code "the old way."
  • Thomas:

    "We will definitely see a world where you have agents across the whole developer life cycle... But there will be thousands if millions of professional software developers that will still write code like we wrote QL code this year." (28:39)

• Human Collaboration Remains Central:
  • Teams, not just agents, will continue to drive innovation and make business decisions.
