Build 2026 is on in San Francisco at the moment. I haven’t attended Build since my analyst days (I work at GitHub now), but the recovering analyst in me would love to have been at this years event, it looks awesome for a distance. Everyone will have their favorite releases, but here are my top three GitHub related releases:

  • Sandboxes for Copilot. This brings simple, clean, isolation when your using the CLI and other form factors (I live in the CLI these days, although I am increasingly using the new GitHub Copilot App). Longer term sandboxes are going to be the only way enterprises will permit agents to run either locally or in the cloud.

  • MAI-Code-1-Flash Model. MAI-Code-1-Flash is a new, Microsoft developed, model. It excels in price/performance for light weight coding flows. How we use models is rapidly changing, and the days of rushing to the latest shiny (and uber expensive) frontier model are coming to a close.

  • Learning from your sessions with /chronicle. Learning from, and improving, how we use AI - what we do in our sessions - is going to be a key skill for every developer. Your sessions across surfaces can be synced to GitHub, and using /chronicle you can do things such as creating summaries of what you have done, suggesting improvements and working out more cost effective ways of working. Longer term the possibilities here are endless.
