Most vector search slows down as you scale from millions to billions to trillions of vectors - latency creeps up. Native vector search in Amazon DynamoDB is different: single-digit ms latency with 99%+ recall, at any scale. Now GA. go.aws/3TyKOyt

🚀 Excited to share that applications are now open for the 2026 AWS AI & ML Scholars program powered by AWS Skill Builder ➡️ aws.amazon.com/about-aws/our… This program matters to me personally because I know how access to education and strong technical training can change the trajectory of someone's life. Growing up, I saw this firsthand and that experience has stayed with me throughout my career. This year, we're providing free AI education to up to 100,000 learners worldwide through the program. No prior experience required. No cost. Just a commitment to learn. New this year, everyone who completes the Challenge phase also earns three free months of AWS Skill Builder. The top 4,500 performers advance to fully funded @udacity Nanodegrees in AI Programming, and Agent development. Take advantage of the chance to start your AI learning journey and enroll into the program before June 24th.

Pro tip: next time you use an #LLM to write your post, maybe add one more #prompt — “remove em dashes so people don’t instantly clock this as AI.” Nothing screams “I didn’t write this” louder than perfectly polished sentences — with dramatic pauses — every other line. #thought
