Scaling models and system limits

Rajat Monga, CVP AI Frameworks @ Microsoft, joins the podcast to discuss his leadership and founder journey, from Google Brain / Tensorflow to inference.io and back to Microsoft. He dissects what it means to refound vs. start from scratch, the value of the open source community, and strategies for discovering what problem to solve when going the startup route. We also cover how to determine your users’ hidden incentives and what that means for both product development & marketing, along with navigating the balance between a product’s usefulness and consumers’ willingness to pay for it. Additionally, Rajat shares about what he’s currently up to at Microsoft and the emerging ML / AI technologies he’s most excited about.

ABOUT RAJAT MONGA

Rajat Monga is responsible for enabling an efficient AI stack at Microsoft from cloud to the edge. Before joining Microsoft, Rajat was founder and CEO of Inference.io, a smart analytics platform powered by AI. During his decade-long tenure at Google, he co-founded and led TensorFlow, and was a founding member of Google Brain. He’s built out and led many engineering teams, and designed large scale distributed systems including web scale crawling and eBay’s search engine. Rajat is a graduate of IIT Delhi.

Unblocked: The context engine your coding agents are missing.

Give your coding agents the context your best engineers have.

Your agents can read code, but they don’t know how your team works. Rules and MCPs give access to information but not understanding. That’s why you still have to tell them where to look and what to look for.

Unblocked gives your agents the history, conventions, and decisions behind your code so they generate mergeable output without the back and forth. It automatically surfaces the right context for every task, so agents stay on track without the set up tax or the correction loops.
