HOW BRAZE'S CTO IS RETHINKING ENGINEERING FOR THE AGENTIC AREA

Summary from the TLDR Dev newsletter

Braze shifted to AI-first engineering in a few months, with 60%+ of committed code now AI-generated. Adoption was driven by model quality (Claude Code, Opus 4.5) and a greenfield MCP server. Now the problem they're dealing with is inference cost, as engineers are spending tens or hundreds of dollars a day on using AI.
