Training questions at OpenAI
Design a Distributed Training Platform for Foundation Models
4/5Architect a massive, highly available distributed infrastructure designed to train giant foundation models across thousands of accelerators simultaneously, as featured in an OpenAI system design interview. This problem focuses on orchestrating synchronous workloads, handling rapid fault recovery, optimizing data pipelines, and managing model parallelism strategies like tensor and pipeline sharding. You will also tackle scheduling fairness and network bottlenecks. Unlock the full design breakdown and expert architectural solution with a subscription.
System Design for MLOpenAIReproduce Double Descent in Linear Regression
3/5Recreate the double-descent curve in the simplest possible setting: ordinary least squares on synthetic Gaussian data, sweeping the parameter count from well under the sample size to well over it. Asked at OpenAI, this task tests whether you can set up a clean experiment and then explain the test-error spike at the interpolation threshold instead of hand-waving at it. You will manage the under- and over-parameterised regimes, the role of noise, and why the minimum-norm solution recovers as capacity grows.
