Final week, my group met many builders at Developer Week in San Jose. My colleague, Vinicius Senger delivered an excellent keynote about renascent software program—a brand new means of constructing and evolving functions the place people and AI collaborate as co-developers utilizing Kiro. Different colleagues spoke about constructing and deploying production-ready AI brokers. Everybody stayed to ask and listen to the questions associated to agent reminiscence, multi-agent patterns, meta-tooling and hooks. It was fascinating what number of builders had been truly constructing brokers.

We’re persevering with to satisfy builders and listen to their suggestions at third-party developer conferences. You possibly can meet us on the dev/nexus, the most important and longest-running Java ecosystem convention on March 4-6 in Atlanta. My colleague, James Ward will talk about constructing AI Brokers with Spring and MCP, and Vinicius Senger and Jonathan Vogel will talk about 10 instruments and tricks to improve your Java code with AI. I’ll preserve sharing locations so that you can join with us.

Final week’s launches

Listed here are among the different bulletins from final week:

Claude Sonnet 4.6 mannequin in Amazon Bedrock – Now you can use Claude Sonnet 4.6 which presents frontier efficiency throughout coding, brokers, {and professional} work at scale.
