Perplexity Python SDK Tutorial: LLM API in 3 Lines of Code (2026)

A new Perplexity Python SDK just dropped on PyPI — here's everything you need to know, plus how NexaAPI gives you access to 56+ AI models including LLMs with one simple SDK at a fraction of the cost.

What Is pplx-python-sdks-llm-api?

A new package called pplx-python-sdks-llm-api (version 0.1.2) was uploaded to PyPI on March 27, 2026. This signals growing developer interest in Perplexity's LLM API — and a spike in searches for Python tutorials around it.

Perplexity offers a set of Sonar models for LLM and search-augmented generation:

Model Input (per 1M tokens) Output (per 1M tokens) Best For
sonar $1.00 $1.00 Basic search + synthesis
sonar-reasoning $1.00 $5.00 Multi-step reasoning
sonar-reasoning-pro $2.00 $8.00 Complex reasoning
sonar-pro $3.00 $15.00 Enhanced accuracy
sonar-deep-research $2.00 $8.00 Deep research tasks

These are search-augmented models — great for web-aware queries, but limited to Perplexity's own model family. No image generation, no video, no audio.

How to Use Perplexity's LLM API in Python

Perplexity's API is OpenAI-compatible, so you can use the official OpenAI client:

from openai import OpenAI

client = OpenAI(
    api_key="YOUR_PERPLEXITY_API_KEY",
    base_url="https://api.perplexity.ai"
)

response = client.chat.completions.create(
    model="sonar",
    messages=[
        {"role": "user", "content": "What is quantum computing?"}
    ]
)

print(response.choices[0].message.content)
# Cost: $1/1M input + $1/1M output tokens
Enter fullscreen mode Exit fullscreen mode

This works, but you're locked into Perplexity's model catalog. What if you want to switch to Llama, generate an image, or create a video — all from the same codebase?

NexaAPI — One SDK for 56+ AI Models

NexaAPI gives you access to 56+ AI models — LLMs, image generation, video, audio — all from a single Python or JavaScript SDK. Cheaper than Perplexity. No model lock-in.

Install 

pip install nexaapi
Enter fullscreen mode Exit fullscreen mode

PyPI: https://pypi.org/project/nexaapi/

Python Code Example 

# pip install nexaapi
from nexaapi import NexaAPI

client = NexaAPI(api_key='YOUR_API_KEY')

# LLM text generation — cheaper than Perplexity API
response = client.chat.completions.create(
    model='llama-3.1-70b',
    messages=[
        {'role': 'user', 'content': 'Explain quantum computing in simple terms'}
    ]
)

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

# Bonus: generate an image with the SAME SDK — $0.003/image
image_response = client.images.generate(
    model='flux-schnell',
    prompt='A futuristic quantum computer visualization'
)
print(image_response.data[0].url)
Enter fullscreen mode Exit fullscreen mode

JavaScript Code Example 

// npm install nexaapi
import NexaAPI from 'nexaapi';

const client = new NexaAPI({ apiKey: 'YOUR_API_KEY' });

async function main() {
  const response = await client.chat.completions.create({
    model: 'llama-3.1-70b',
    messages: [
      { role: 'user', content: 'Explain quantum computing in simple terms' }
    ]
  });
  console.log(response.choices[0].message.content);

  const imageResponse = await client.images.generate({
    model: 'flux-schnell',
    prompt: 'A futuristic quantum computer visualization'
  });
  console.log(imageResponse.data[0].url);
}
main();
Enter fullscreen mode Exit fullscreen mode

Price Comparison: NexaAPI vs Perplexity vs OpenAI

Provider LLM API Cost Image Generation Models Available
NexaAPI Competitive $0.003/image 56+
Perplexity $1–$3/1M input Not available 6 (Sonar family only)
OpenAI $0.15–$15/1M input $0.04+/image Limited

NexaAPI is available on RapidAPI: https://rapidapi.com/user/nexaquency

Why Choose NexaAPI?

  1. One SDK, 56+ models — LLMs, FLUX image generation, video, audio, all in one place
  2. Cheaper pricing — $0.003/image is 13x cheaper than OpenAI's DALL-E
  3. No model lock-in — switch between Llama, Mistral, FLUX, Veo, and more
  4. OpenAI-compatible — drop-in replacement, minimal code changes
  5. Pay as you go — no subscription required

Conclusion

The new pplx-python-sdks-llm-api package on PyPI shows that developers are actively looking for Perplexity API Python tutorials. While Perplexity's Sonar models are solid for search-augmented LLM tasks, they're limited to one model family and don't support image, video, or audio generation.

NexaAPI gives you 56+ models — including LLMs comparable to Perplexity's Sonar — plus image generation at $0.003/image, all from one SDK.
