AI Agents for Education: Generate Full Course Materials with Multimedia via NexaAPI

What is instructional-agents?

instructional-agents is a research-backed Python package accepted at EACL 2026 Main Conference. It implements the ADDIE instructional design model using multi-agent LLM collaboration to automatically generate:

NexaAPI: Add Multimedia to Your Course Agents

NexaAPI gives your educational AI agents access to 50+ models for images, audio, and video — all under one API key.

Python: Add Images to Your Course Agent

# pip install nexaapi instructional-agents
from nexaapi import NexaAPI

client = NexaAPI(api_key='YOUR_API_KEY')
# Free key at https://nexa-api.com

def generate_course_visual(topic: str, lesson_title: str):
    """Generate an educational diagram for a lesson."""
    prompt = f'Educational diagram explaining {topic}, clean infographic style, suitable for students, white background, labeled'
    response = client.images.generate(
        model='flux-schnell',  # check nexa-api.com for current models
        prompt=prompt,
        width=1024,
        height=768
    )
    image_url = response.data[0].url
    print(f'Course visual for "{lesson_title}": {image_url}')
    return image_url

def generate_audio_narration(text: str, lesson_title: str):
    """Generate TTS narration for course content."""
    response = client.audio.speech(
        model='tts-1',
        input=text,
        voice='alloy'
    )
    print(f'Audio narration for "{lesson_title}" generated')
    return response

# Example usage
lesson = 'photosynthesis in plants'
title = 'Biology 101: Photosynthesis'

visual = generate_course_visual(lesson, title)
audio = generate_audio_narration(
    'Photosynthesis converts sunlight into energy using CO2 and water.',
    title
)
print(f'Cost: ~$0.003 per image — cheapest AI image API available')

JavaScript: Same in Node.js

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

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

async function generateCourseVisual(topic, lessonTitle) {
  const response = await client.images.generate({
    model: 'flux-schnell',
    prompt: `Educational diagram explaining ${topic}, clean infographic, white background`,
    width: 1024,
    height: 768
  });
  const imageUrl = response.data[0].url;
  console.log(`Course visual for "${lessonTitle}": ${imageUrl}`);
  return imageUrl;
}

async function generateAudioNarration(text, lessonTitle) {
  const response = await client.audio.speech({
    model: 'tts-1',
    input: text,
    voice: 'alloy'
  });
  console.log(`Audio for "${lessonTitle}" generated`);
  return response;
}

(async () => {
  const visual = await generateCourseVisual('photosynthesis', 'Biology 101');
  const audio = await generateAudioNarration(
    'Photosynthesis converts sunlight into energy.',
    'Biology 101'
  );
  console.log('Full multimedia course material generated!');
  console.log('Cost: ~$0.003/image');
})();
