Overview
What this challenge is about.
DPO Fine-Tune for a Domain-Specific Writing Assistant. Advanced challenge in code. Writing production code that solves real engineering problems, earn a bloc...
The Brief
What you'll do, and what you'll demonstrate.
Run DPO on a fundraising-writing model to beat the base model in editor-blind preference without cratering general capability.
This is not a coding exercise. It is the work a software engineer does between a Jira ticket and a merged PR. That distinction matters to every hiring manager who has seen candidates solve LeetCode problems and none who have shipped production code under real constraints.
When you finish, you will have something most graduates do not: a real-world deliverable, verified by Ewance, that you can show to a hiring manager and say "I did this. Here is the proof."
Earning criteria — what you'll demonstrate
- Implement DPO training with the TRL library
- Design and run an editor-blind head-to-head win-rate study
- Detect capability regressions during preference fine-tuning
- Communicate post-training results to a non-ML founder
