Phase 3: Direct AI API Access
Unlock the Full Power of AI Models — Directly
Welcome to Phase 3 (AI APIs & Vibe Coding). In the next 3 hours, you'll move beyond consumer AI interfaces and connect directly to the world's most capable AI models. You'll compare providers, understand costs, and build a multi-model command centre that saves you money while delivering superior results.
Workshop Overview
This phase transforms you from an AI subscription consumer into a professional who commands multiple AI models through their APIs. You'll set up accounts with Anthropic (Claude), OpenAI (GPT), and Google (Gemini), test each model head-to-head, and learn the token economics that make direct API access 10x cheaper than monthly subscriptions.
Learning Outcomes

Pro Tips for Success
- Set spending limits first: Every provider lets you cap monthly spend. Do this before anything else.
- Start with the cheapest models: Haiku 4.5 and GPT-4o-mini handle most tasks brilliantly.
- Keep a comparison log: Note which model impressed you for each task type.
- Don't memorise pricing: It changes frequently. Bookmark the provider consoles.
- Use your real work: Generic test prompts won't reveal which model suits your needs.
