It is not enough to know which AI: use it well

Choosing the right program is only the first step. I highlight Claude: how to use it, how to write a good prompt, and when to switch models.

  1. Choose wellthe right program
  2. Use it wellthe program you chose
  3. Switch wellbetween language models

Based on my own experience.

The basics

A good program is not enough, you have to use it well

It is not enough to know which program serves our needs. You have to use it well too.

Claude

Did you know it has a program function?

A dear friend of mine, until I showed him that Claude has a program function, was trying to get by on the plain chat interface for everything.

Many people do this: they know the tool but only use one side of it. It is worth going through everything it offers.

Good prompt

Back to the Harry Potter case

A good prompt is precise. In the video article I described what happened to me: I asked for a Harry Potter example in the prompt and got a magical-world background with sparkles. It didn’t look bad, but it wasn’t what I expected. I designed the prompt wrongly.

The lesson: before you send it, think through exactly what you want.

A prompt from another model

Any other model can do

Any other model can be good for writing the prompt. Next to Claude, I have ChatGPT or Grok word the prompt.

With the right settings, these prompts can also be taken apart and split into parts inside Claude. That way I can decide which part of the task which language model should handle.

Context and saving

New conversations, switching models, building with intent

I open a new conversation several times, switch between language models, and try to word my requests well.

I pay attention to when I use which language model. I only start building when there is really a concrete idea and a plan for it.

Choice

The three most important things

  1. Choosing the right programKnow which program is for what, and don’t only use one side of it.
  2. Using the program wellA precise prompt, a new conversation when needed, and building with intent.
  3. Switching well between language modelsPick the right model for each part of the task.
Tips

What to watch out for

  • A precise prompt: think through what you want before you send it. A bad prompt gives a bad result.
  • A new conversation: don’t let one conversation get too long. Open a new one more than once, and word the request well.
  • Plan first: only start building once you have a concrete idea and a plan.
