ChatGPT: The Foundation Model Every Operator Should Know
OpenAI's flagship chatbot — the default AI assistant for writing, coding, research, and reasoning. Here's how serious operators actually use it.
ChatGPT is the default. Pick a different foundation model only if you have a specific reason — Claude for longer documents, Gemini for Google integration, Perplexity for cited research. Otherwise, start here.
What ChatGPT does well
The killer feature isn’t any single capability — it’s the ecosystem. Custom GPTs let you build single-purpose tools. The OpenAI API powers half the AI products you’ve heard of. Voice mode is genuinely good. Image generation is built in.
What it doesn’t do well
It will confidently lie about facts when it doesn’t know. It can’t natively browse without being told to. Its memory feature is helpful but quirky. The free tier is fine for tire-kicking but useless for daily work.
Who should pay for ChatGPT Plus
Anyone using ChatGPT more than 30 minutes a day. The $20/month buys you GPT-5 access, longer context windows, no rate limits, voice mode, and DALL·E image generation. If you bill more than $50/hr for your time, the math is trivial.
Workflow recommendations
Use ChatGPT for the first draft of everything: emails, code, blog posts, presentations, strategy docs. Then edit ruthlessly. The 80% draft in 30 seconds is the win — not the polished output (which still requires you).
