# Multimodal AI Skill

**Communication: User's language. Code: English.**

## Purpose

Handles multimodal AI applications. Covers vision, image generation, video generation, speech, and voice synthesis.

## Scope

| Area | Coverage |
|------|----------|
| **Vision** | GPT-4o Vision, Gemini Vision, image understanding |
| **Image Generation** | DALL-E 3, Midjourney, Stable Diffusion |
| **Video Generation** | Sora, Runway, Pika |
| **Speech-to-Text** | Whisper, Deepgram, AssemblyAI |
| **Text-to-Speech** | OpenAI TTS, ElevenLabs, Google TTS |
| **Voice** | Real-time voice, voice cloning |

## Quick Start

| Task | Files |
|------|-------|
| Vision API | vision-basics.md → vision-applications.md |
| Image generation | img-gen-basics.md → img-gen-tools.md |
| Video generation | video-gen-basics.md → video-gen-tools.md |
| Speech-to-text | speech-to-text-basics.md → speech-to-text-advanced.md |
| Text-to-speech | tts-basics.md → tts-implementation.md |
| Voice synthesis | voice-basics.md → voice-implementation.md |

## Code Examples

### GPT-4o Vision

```python
from openai import OpenAI

client = OpenAI()

response = client.chat.completions.create(
    model="gpt-4o",
    messages=[{
        "role": "user",
        "content": [
            {"type": "text", "text": "What's in this image?"},
            {"type": "image_url", "image_url": {"url": "https://..."}}
        ]
    }]
)
```

### DALL-E 3 Image Generation

```python
from openai import OpenAI

client = OpenAI()

response = client.images.generate(
    model="dall-e-3",
    prompt="A futuristic city with flying cars",
    size="1024x1024",
    quality="hd",
    n=1
)

image_url = response.data[0].url
```

### Whisper Speech-to-Text

```python
from openai import OpenAI

client = OpenAI()

audio_file = open("speech.mp3", "rb")
transcription = client.audio.transcriptions.create(
    model="whisper-1",
    file=audio_file,
    response_format="verbose_json",
    timestamp_granularities=["word"]
)

print(transcription.text)
```

### OpenAI TTS

```python
from openai import OpenAI
from pathlib import Path

client = OpenAI()

response = client.audio.speech.create(
    model="tts-1-hd",
    voice="alloy",
    input="Hello, this is a test of text to speech."
)

response.stream_to_file("speech.mp3")
```

### Gemini Vision

```python
import google.generativeai as genai

genai.configure(api_key="...")
model = genai.GenerativeModel('gemini-pro-vision')

image = PIL.Image.open("image.jpg")
response = model.generate_content([
    "Describe this image in detail",
    image
])

print(response.text)
```
