Episode notes
AI Appears Cheap Because Providers Subsidize Usage
- AI is not inherently cheap; cloud providers heavily subsidize consumer plans to create habit formation.
- Christopher Penn notes enterprise users see true token costs and can receive unexpectedly large bills when usage is unrestricted.
Run Open Weights Locally To Slash AI Costs
- Consider open-weights models to cut costs, keep data private, and still get capability close to closed models.
- Christopher Penn recommends running downloaded models on your own hardware to pay essentially electricity instead of large API bills.
Open Weights Models Let You Own The 'Engine'
- Open-weights models are downloadable 'engines' you can run yourself, while closed-weights models hide the engine behind a corporate API.
- Penn uses a car analogy: the model is the engine and client apps are the car body and dashboard.
