Custom instructions for ChatGPT

OpenAI just launched custom instructions for ChatGPT. You can now set a default set of instructions for every new chat. Using language to configure your LLM!

I’ve been waiting for this feature for a long time, and it’s as great as I’d hoped.

My current custom instructions:

- Respond in UK English.
- Succinct responses without superfluous words.
- Avoid complex words or jargon.
- Use bullet points wherever possible.
- Stay neutral and unopinionated.
- Avoid preamble.

Now I get very concise answers, like:

Risks of salbutamol use include:

• Palpitations
• Tremors
• Nervousness
• Headache
• Muscle cramps
• Dry mouth or throat irritation
• Increased heart rate
• Low potassium levels (hypokalemia)
• Cough
