Hey —

Let’s talk about something almost no one explains well:

Context windows.

It’s one of the most important (and misunderstood) concepts in AI today — and it’s quietly powering everything from better content to fully autonomous agents.

At a basic level, a context window is how much information an AI model can “hold in mind” at once.

In simpler terms?

It’s short-term memory.

Here’s what that looks like:

  • GPT‑3.5 = 4,000 tokens (roughly 3,000 words)

  • GPT‑4o = 128,000 tokens

  • Gemini 1.5 = 2,000,000 tokens — yes, 2 million

Why does this matter?

Because the bigger the window, the more the AI can understand — all at once.

You can now:

  • Upload full transcripts, books, or project docs

  • Give it entire client histories, and have it reply with nuance

  • Ask it to reason across long conversations, timelines, or sales funnels

  • Build workflows that feel like talking to a teammate — not a tool

This isn’t prompt engineering.
It’s context engineering — and it’s where the real leverage lives.

Most people are still prompting AI like it’s 2022.
But the real advantage in 2025?
Is giving AI more, not less.

More inputs.
More memory.
More responsibility.

Because if it can hold the whole map — it can help you navigate it.

If you’re ready to go beyond simple prompts and start designing workflows that think, not just write…

You’ll learn:

  • How to build context-aware prompts and workflows

  • How to turn AI into a daily income-producing assistant

  • How to structure input, output, and action like a real system — not a toy

It’s not about asking better questions.
It’s about giving better context.

That’s how you win with AI.
