  AI Summer Adventure

  Nufar Gaspar, with The AI Daily Brief and Superintelligent

  Twenty-three interactive building stations across three skill tiers, done at your own pace.

  What you actually build

  • Everyday productivity assistantsTier one works on the daily grind — turning messy notes and transcripts into something you would actually send.
  • Custom knowledge assistantsTier two builds assistants that answer from documents you supply, rather than from whatever the model happens to know.
  • Autonomous agents and multi-tool workflowsTier three chains steps together so a task runs without you sitting over it.

  OpenAI Academy

  OpenAI

  Self-paced video modules with sandbox exercises, plus live and recorded sessions.

  What you actually build

  • Structured output you can rely onGetting clean, consistent formatting out of unstructured input — the difference between a demo and something a process can depend on.
  • A custom assistant for your teamConfiguring an assistant with its own instructions and reference documents, so it answers the way your function needs.
  • Workflows that run in stepsBreaking a large task into stages an assistant handles in sequence, which is where agents start to be useful rather than impressive.

  AI Prompting for Everyone

  DeepLearning.AI, taught by Andrew Ng

  Video lectures with guided browser exercises. No coding at any point.

  What you actually build

  • Dense reports into executive summariesWorking a long document down to the version a board would read, and knowing what got lost.
  • The model as a criticInstructing it to argue against you as a sceptical director or a strict editor, which is where it earns its keep.
  • Thinking through an ambiguous problemUsing it on scenarios that have no clean answer, rather than on tasks you already know how to do.

  Where it costsThe videos are free. Labs, quizzes and the certificate need a Pro membership at $25 a month, billed annually.

Role-specific courses that work on your own material — your contracts, your close, your campaign brief.

  What you actually build

  • What the technology is actually doingHow a prediction gets made, and where machine learning differs from ordinary software that follows rules.
