# KB: OpenAI Integration & Hybrid AI

The EbookBuilder system now supports a hybrid AI architecture, combining the open-source power of Hugging Face with the advanced reasoning and generative capabilities of OpenAI.

## 1. GPT-4o Integration
- **Function**: `generate_content_openai`
- **Role**: High-fidelity drafting, complex character development, and intricate plot planning.
- **Why**: Use GPT-4o for tasks that require the highest level of linguistic nuance or multi-step logic.

## 2. DALL-E 3 Integration
- **Function**: `generate_image_dalle`
- **Role**: Premium cover design and photorealistic internal illustrations.
- **Why**: DALL-E 3 excels at following complex visual instructions and embedding text into images.

## 3. Hybrid Orchestration
The **Meta Orchestrator** has been upgraded to route tasks dynamically between HF and OpenAI based on the requirements:
- **Research/Fact-Checking**: Handled by Llama-3 (HF).
- **Prose/Creativity**: Handled by GPT-4o (OpenAI).
- **Marketing/Commerce**: Handled by Llama-3 (HF).

## Setup
To use these features, ensure the `OPENAI_API_KEY` environment variable is set in your session.
