Where Your Agent Lives on the Accuracy–Latency–Cost FrontierDec 15, 2025
Every agent harness trades off accuracy, latency, and cost. Five lessons from navigating the frontier.
Hi, I'm Purak Jain, an applied scientist.
I research and build multi-agent AI systems, currently working on multi-agent coordination, continual learning memory, and RL-ready evaluation sandboxes for AWS Frontier Agents with a team of scientists I lead across Seattle, San Francisco, and New York. Before that, I spent 8 years in Amazon Advertising building bidding algorithms, incrementality measurement, and recommender systems that optimized over $1B in global ad spend across Google, Meta, and YouTube.
I write here about things I am learning.
