How to make AI writing sound more human

Quick answer

To make AI writing sound more human, use prompt engineering techniques like adding personality, context, and conversational tone in ChatGPT prompts. Adjust temperature and model parameters such as temperature and top_p to increase creativity and naturalness.

PREREQUISITES

Python 3.8+
OpenAI API key (free tier works)
pip install openai>=1.0

Setup

Install the OpenAI Python SDK and set your API key as an environment variable to interact with ChatGPT models.

bash

pip install openai>=1.0

Step by step

Use prompt design and model parameters to generate more human-like text. Add instructions for tone and style, and set temperature to around 0.7 for creativity.

python

import os
from openai import OpenAI

client = OpenAI(api_key=os.environ["OPENAI_API_KEY"])

prompt = (
    "Write a friendly and conversational email explaining a project delay. "
    "Use natural language with empathy and casual tone."
)

response = client.chat.completions.create(
    model="gpt-4o",
    messages=[{"role": "user", "content": prompt}],
    temperature=0.7,
    top_p=0.9
)

print(response.choices[0].message.content)

output

Hi there,

I wanted to update you on the project timeline. We've hit a small snag that’s causing a delay, but we're working hard to get back on track. Thanks for your patience and understanding!

Best,
[Your Name]

Common variations

You can experiment with different models like gpt-4o-mini for faster responses or claude-3-5-sonnet-20241022 for more nuanced tone. Async calls and streaming completions are also options for interactive apps.

python

import os
from openai import OpenAI

client = OpenAI(api_key=os.environ["OPENAI_API_KEY"])

async def generate_human_text():
    response = await client.chat.completions.acreate(
        model="gpt-4o-mini",
        messages=[{"role": "user", "content": "Write a warm thank you note."}],
        temperature=0.8
    )
    print(response.choices[0].message.content)

# To run async, use an async event loop like asyncio.run(generate_human_text())

output

Thank you so much for your kindness and support! It truly means a lot to me.

Troubleshooting

If the output sounds robotic or repetitive, increase temperature or add more detailed style instructions in the prompt. If responses are off-topic, clarify context or add examples.

Key Takeaways

Use prompt instructions to specify tone, style, and personality for human-like writing.
Adjust temperature and top_p parameters to control creativity and naturalness.
Experiment with different models and async calls for varied response styles and performance.
Clarify context and add examples in prompts to reduce robotic or irrelevant outputs.
