Nufar Gaspar, an operator and AI practitioner who builds enterprise AI workflows and token-economics frameworks. She explains what AI tokens are, why agentic loops spike costs, and how to tell useful usage from waste. Short, practical takes on measuring cost per accepted task, spotting “spinning” tokens, model selection, and protecting experimentation while cutting needless spend.

Episode notes
Tokens Aren't Universal Across Models
- Tokens vary by provider because each model lab uses its own tokenizer and vocabulary size.
- The same document can be 10–45% more tokens on one provider, so dollars-per-task beats dollars-per-token for comparisons.
Input, Reasoning, And Output Have Different Costs
- Every request has three token layers: input (cheap), reasoning (hidden, billed at output rates), and output (most expensive).
- Reasoning tokens can multiply cost 4–20x and are often invisible until billed.
Optimize Dollars Per Accepted Task
- The right metric is cost per accepted task, not price per token, because models and harnesses change iteration counts and success rates.
- Databricks found a model cheaper per token could be costlier per task due to extra iterations.
