Title:
Large Sequence Models for Software Development Activities
Abstract:
Large language models for software are increasingly moving beyond code completion to the full range of software development activities that engineers engage in day-to-day. I will present an overview of Google’s efforts to build large foundation models trained on Google’s own internal software-engineering logs, dubbed DIDACT. These logs, and the resulting DIDACT models, capture not just code and code editing, but also code review, bug fixing, code-change vetting and approvals, and other such developer activities, and enable diverse and powerful software-engineering AI assistants. I will dive more deeply into one such internal assistant built on top of DIDACT, and deployed to all Google engineers, used to suggest code edits that resolve code-review comments. I will detail not just the assistant’s design, but also the journey to adapt it for effective use in production. This comment-resolution assistant is addressing more than 7.5% of code-review comments at Google, providing significant positive impact on real-world engineer productivity. This talk covers work by teams from Google’s DeepMind, Research, and Core Systems & Experiences divisions.
