# TorchTransformers Diffusion CV SFT Titans 🚀

A Streamlit app blending `torch`, `transformers`, and `diffusers` for vision and NLP fun! Snap PDFs 📄, turn them into double-page spreads 🖼️, extract text with GPT 🤖, and craft emoji-packed Markdown outlines 📝—all with a witty UI and CPU-friendly SFT.

## Integration Details

1. **SFT Tiny Titans (First Listing)**:
   - Features: Causal LM and Diffusion SFT, camera snap, RAG party.
   - Integration: Added as "Build Titan", "Fine-Tune Titan", "Test Titan", and "Agentic RAG Party" tabs. Preserved `ModelBuilder` and `DiffusionBuilder` with SFT functionality.
2. **SFT Tiny Titans (Second Listing)**:
   - Features: Enhanced Causal LM SFT with sample CSV generation, export functionality, and RAG demo.
   - Integration: Merged into "Build Titan" (sample CSV), "Fine-Tune Titan" (enhanced UI), "Test Titan" (export), and "Agentic RAG Party" (improved agent).
3. **AI Vision Titans (Current)**:
   - Features: PDF snapshotting, OCR with GOT-OCR2_0, Image Gen, GPT-based text extraction.
   - Integration: Added as "Download PDFs", "Test OCR", "Test Image Gen", "PDF Process", "Image Process", and "MD Gallery" tabs. Retained async processing and gallery updates.
4. **Sidebar, Session, and History**:
   - Unified gallery shows PNGs, PDFs, and MD files from all tabs.
   - Session state (`captured_files`, `builder`, `model_loaded`, `processing`, `history`) tracks all operations.
   - History log in sidebar records key actions (snapshots, SFT, tests).
5. **Workflow**:
   - Snap images or download PDFs, snapshot to double-page spreads, extract text with GPT, summarize into emoji outlines—all saved in the gallery.
6. **Verification**:
   - Run: `streamlit run app.py`
   - Check: Camera snaps, PDF downloads, GPT text extraction, and Markdown outlines in gallery.
7. **Notes**:
   - PDF URLs need direct links (e.g., arXiv’s `/pdf/` path).
   - CPU defaults with CUDA fallback for broad compatibility.

## Automation Instructions: Witty & Funny Steps 😂

1. **Load PDFs** 📚  
   - Drop URLs into “Download PDFs 📥” or upload files.  
   - *Emoji Tip*: 🦁 Unleash the PDF beast—roar through arXiv!

2. **Double-Page Snap** 📸  
   - Click “Snapshot Selected 📸” with “Two Pages (High-Res)”—landscape glory!  
   - *Witty Note*: Two pages > one, because who reads half a comic? 🦸

3. **GPT Vision Zap** ⚡  
   - In “PDF Process 📄”, pick a GPT model (e.g., `gpt-4o-mini`) and zap text out.  
   - *Funny Bit*: GPT’s like “I see text, mortals!” 👁️

4. **Markdown Mash** 📝  
   - “MD Gallery 📚” takes Markdown files, smashes them into a 12-point emoji outline.  
   - *Sassy Tip*: 12 points—because 11’s weak and 13’s overkill! 😜

## Innovative Features 🌟

- **Double-Page Spreads**: High-res, landscape images from PDFs—perfect for apps! 🖥️
- **GPT Model Picker**: Swap `gpt-4o` for `gpt-4o-mini`—speed vs. smarts! ⚡🧠
- **12-Point Emoji Outline**: Clusters facts into 12 witty sections—e.g., “1. Heroes 🦸”, “2. Tech 🔧”. 🎉

Flow Explained:
1. 📚 PDFs: Start with one or more PDFs on a topic.
2. 📄 PDF Process: Download and snapshot into high-res double-page spreads.
3. 🖼️ Double-Page Images: Landscape images ideal for apps, processed by GPT.
4. 📝 Markdown Files: Text extracted per document, saved as Markdown.
5. ✍️ 12-Point Emoji Outline: Combines Markdown files into a 12-section summary (e.g., “1. Context 📜”, “2. Methods 🔬”, ..., “12. Future 🚀”).
Run: pip install -r requirements.txt, streamlit run app.py. Snap, process, outline—AI magic! ⚡

5. **Updated arXiv Links**: Refreshed to match current functionality (vision, OCR, GPT, diffusion):
   - Added GOT-OCR2_0, Vision Transformers, GPT-4, and CLIP papers.
   - Kept core papers (Streamlit, PyTorch, etc.) and adjusted for relevance.

### How to Use
- Save this as `README.md` in your project folder.
- View it in a Markdown renderer (e.g., GitHub, VS Code) to see tables and Mermaid diagram rendered.
- Follow the automation steps to process PDFs and generate outlines—perfect for learners exploring AI vision and text summarization!

This README now serves as both a project overview and a tutorial, making it a fun, educational asset for all! 🚀
