Instagram Direct's team partnered with Google to migrate Instagram DMs on Android from legacy Views to Jetpack Compose, rebuilding the codebase as "AI-native," detailed in a deep-dive on the Android Developers' Blog.
Key numbers:
- 50% smaller UI codebase
- 35% faster AI agent execution time
- 32% fewer engineer-agent exchanges
- 33% lower token cost per agent session
The thesis: declarative, leaner Compose code isn't just easier to maintain — it's dramatically more legible to AI coding agents, making a rewrite for the agent era a performance optimization in itself. The collaboration also fed improvements back into Compose for the broader Android ecosystem.
