Marlene Mhangami (Microsoft & GitHub): Copilot & Open Source
Marlene Mhangami describes her role spanning Microsoft and GitHub, the cultural contrast between the enterprise-focused parent and the more playful GitHub, and her developer-advocacy work on Python, open source and Azure APIs. She reports growing Copilot usage — including beginners using it to contribute to open source — and notes Copilot supports models from both Anthropic and OpenAI. The conversation turns to her take on the Mythos announcement right as this part ends.
Marlene Mhangami: Harnesses Matter More Than Models
Marlene Mhangami closes out her segment, saying she loves the Claude models and uses Opus through Copilot, which supports all models. She argues LLMs are generalists trained on the mean, so harnesses like Copilot matter more than raw model choice for specialized domains, and doubts current models are at AGI level. Asked what excites her, she highlights multi-model workflows and GitHub's new Critique release, where one model critiques another's output, before pointing listeners to GitHub Copilot and Copilot CLI.
