Key differences

Perplexity combines AI with live web search to provide up-to-date answers, making it ideal for fact-checking and current events. ChatGPT uses pretrained large language models like gpt-4o to generate conversational responses, creative writing, and support plugins for extended functionality. Perplexity lacks an official API, limiting integration options, while ChatGPT offers robust API access for developers.

Side-by-side example

Task: Ask for a summary of the latest AI model advancements.

python
from openai import OpenAI
import os

client = OpenAI(api_key=os.environ["OPENAI_API_KEY"])
response = client.chat.completions.create(
    model="gpt-4o",
    messages=[{"role": "user", "content": "Summarize the latest advancements in AI models as of 2026."}]
)
print(response.choices[0].message.content)
output
The latest AI models in 2026 include GPT-4o with enhanced multimodal capabilities, Claude 3.5 Sonnet excelling in coding tasks, and Google's Gemini 2.0 Flash offering improved reasoning and speed.

Perplexity equivalent

Perplexity does not provide an official API, but its web interface can be queried for real-time information. Example prompt on Perplexity's platform:
