01Foundation models and how they workTokens, embeddings and transformers explained for somebody who has to make decisions about a model, with nothing in it about building one.02What generative AI is good and bad atThe capabilities worth building on, the failure modes that are properties of the technology and will outlast any model, and how to tell a suitable problem from an unsuitable one.03The foundation model lifecycleThe seven stages that carry a foundation model from raw data to a system in use, and which five of them a team building on somebody else's model actually owns.
Try a question from this domain

A finance team is forecasting the cost of a customer support assistant built on a hosted foundation model. They plan to budget per active user per month. What should they be told about how the cost actually behaves?

  • ACost is billed per user session, so the per user assumption is broadly correct.
  • BCost is fixed once the model is deployed, because inference does not consume metered resources.
  • CCost depends on the number of parameters in the model rather than on usage.
  • DCost is billed per token of input and output, so it scales with conversation length and document size rather than with user count.
