Build SARJO AI Studio Platform

I’m ready to bring SARJO AI STUDIO to life as an all-in-one, browser-based creative suite. The goal is a sleek, professional interface that quietly hides the complexity of multiple deep-learning engines while giving users a single place to generate images, craft videos, write or debug code and hold natural, multilingual conversations.

Core capabilities
• Image generation: prompt-to-picture workflow similar to Stable Diffusion or DALL-E, with style, size and seed controls.
• Video creation: short clip generation or enhancement, ideally leveraging existing APIs such as Pika, Runway or your custom PyTorch/TensorFlow pipeline.
• Code generation: GPT-style assistant that can suggest, refactor and explain snippets in real time.
• Conversational AI: chat interface powered by the same LLM, extended with language translation and automatic text-analysis / summarization functions.

What I expect as deliverables
1. Responsive web app built with any modern stack (React/Next.js + Python/FastAPI, or a comparable setup) that matches a professional-corporate theme.
2. Modular backend where each AI feature sits behind its own microservice or clearly separated module, making upgrades easy.
3. Secure user authentication and a simple credit / usage counter so I can plug in a payment layer later.
4. Clear documentation: setup, model choices, fine-tuning steps and API endpoints.
5. Demo deployment (AWS, GCP or Vercel acceptable) plus a hand-off session to walk me through the code.

The project is green-field, so I’m open to your recommendations on pretrained models, hosting, GPU requirements and cost-saving tricks. Show me examples of similar AI integrations you’ve done and outline how you’d structure the build, and we can get started right away.
