Token Economics & Cost Modeling

• ✓Turn a vendor's per-token price into a real monthly cost, not a naive multiplication
• ✓Name the specific hidden costs a naive estimate misses — context, history, retries, embeddings
• ✓Work out the volume at which self-hosting beats an API, and what that trade actually costs beyond dollars
• ✓Write a cost memo with three volume scenarios and the one number worth watching monthly

Catch a client's cost estimate before the first invoice does — turn "should be pennies" into a real number, at real volume, with the assumption that was wrong named explicitly.
