Estimate the token cost difference for processing 1M Spanish/French product descriptions vs. an English only baseline, and describe correct budget planning.

Define 'fertility' as a tokenizer metric and explain why high fertility for a language is both a fairness and a model performance problem.

What is the 'token tax' and how does it create downstream accuracy disparities across languages?

$50K compute budget, 50B tokens of US legal text, 1.5B parameter model. Defend your tokenizer design.

You are building a 7B model for 25 languages including Hindi, Arabic, and Swahili. Design a fair tokenizer and name what it costs.

When is fine-tuning the wrong tool? Give three situations.

What is the MTEB benchmark for embedding models?

Define the pretraining data wall and its consequence.

Match each use case to the embedding provider that best fits it

Match each embedding provider to a defining feature or pricing fact
