Evaluate Open-Source Embedding Models for a Multilingual Help Center
Overview
What this challenge is about.
Index 4 open-source embedding models on 25,000 help-center articles, benchmark per-language recall, and deliver a decision memo to earn your verifiable certificate.
The scenario
The fintech (~250 staff, USD 6bn annual SME cross-border volume) is moving its help center to a retrieval-first design under a fixed monthly inference budget.
The Brief
What you'll do, and what you'll demonstrate.
Pick the best open-source multilingual embedding default for the help center, accounting for quality, cost, and license per language.
Earning criteria — what you'll demonstrate
- Benchmark open-source embedding models on multilingual retrieval
- Evaluate per-language performance, not just aggregate
- Reason about cost, license, and quality trade-offs together
- Communicate a defensible model-selection decision
