## AI Master Prompt: GPU Bloom - MegaTrain-based LLM Training Platform MVP

**PROJECT OVERVIEW:**
GPU Bloom is a cutting-edge SaaS platform designed to democratize the training of large-scale (100B+ parameter) Large Language Models (LLMs). It addresses the prohibitive hardware costs and accessibility issues by implementing a memory-centric training system inspired by the MegaTrain paper. This system allows users to train LLMs at full precision using a single, powerful GPU, by leveraging host memory (CPU RAM) for parameter and optimizer state storage, treating the GPU as a transient compute engine. Users can upload their models, configure training parameters, monitor progress in real-time, and download their fully trained models. The core value proposition is enabling efficient, cost-effective, and accessible high-precision LLM training for researchers, developers, and small teams without requiring them to own or rent clusters of expensive GPUs.

**TECH STACK:**
- **Frontend:** React (Next.js 14+ with App Router), Tailwind CSS, shadcn/ui for components
- **Backend:** Next.js API Routes / Node.js
- **ORM:** Drizzle ORM with PostgreSQL (or a compatible SQL database like SQLite for local dev/simpler deployment)
- **Authentication:** NextAuth.js (using credentials provider and potentially OAuth for Google/GitHub)
- **State Management:** React Context API and Zustand for global state, component-local state for forms/UI elements.
- **Real-time Updates:** Server-Sent Events (SSE) or WebSockets for live monitoring dashboard.
- **Deployment:** Vercel (recommended for Next.js) or a similar platform supporting Node.js runtimes.
- **Other:** Zod for schema validation, React Hook Form for forms, charting library (e.g., Chart.js or Recharts) for monitoring graphs.

**CORE FEATURES & USER FLOW:**

1.  **Authentication & User Management:**
    *   **Flow:** User lands on the homepage. Clicks 'Sign Up' or 'Login'. Redirected to Auth page. Options: Email/Password or OAuth (Google/GitHub). Upon successful login, user is redirected to their Dashboard. User profile page allows viewing/editing basic info and managing subscription (future).
    *   **Details:** Use NextAuth.js. Implement email verification for credential sign-up. Securely store passwords (hashed). Handle session management. Protect all routes except landing page and auth pages.

2.  **Project Creation:**
    *   **Flow:** Logged-in user navigates to 'Projects' tab. Clicks 'New Project'. A modal or form appears asking for Project Name, Description, Model Architecture (dropdown: Transformer, Custom), Model Size (input: e.g., 120), Training Data Path (input/upload link). Click 'Create Project'. Project is saved to DB and user is redirected to the project details page.
    *   **Details:** Use `react-hook-form` and `zod` for validation. Store project metadata in `projects` table. Training data path will initially be a placeholder; actual data handling is complex for MVP.

3.  **Training Job Configuration & Launch:**
    *   **Flow:** User views a specific project. Clicks 'Start New Training Job'. A detailed form appears: Training Configuration (JSON input or structured fields for learning rate, batch size, epochs, optimizer choice etc.), GPU Type (dropdown: H200), Host Memory (input, e.g., 1536 GB). User clicks 'Start Training'. A new entry is created in `trainingJobs` table with status 'queued'. A backend process (or separate worker service) picks up 'queued' jobs and initiates the MegaTrain simulation/process.
    *   **Details:** The actual MegaTrain execution will be simulated or integrated via an API call to a specialized backend service in MVP. The backend service will manage GPU allocation (simulated in MVP by assigning a job ID to a conceptual GPU). User config is stored in `trainingJobs.config` (JSONB).

4.  **Real-time Training Monitoring:**
    *   **Flow:** User navigates to the 'Training Jobs' list or a specific job's detail page. If a job is 'running', a live dashboard appears. This dashboard fetches metrics from the `trainingMetrics` table via SSE/WebSockets. Graphs display Loss, Learning Rate, GPU/CPU Utilization, Memory Usage over time. Key stats (current epoch, step, throughput) are displayed prominently.
    *   **Details:** Backend process responsible for the training job will push metrics to the `trainingMetrics` table periodically. Frontend client subscribes to these updates via SSE or WebSockets, updating the UI dynamically without full page reloads.

5.  **Model Download / Management:**
    *   **Flow:** Once a training job status is 'completed', the user sees a 'Download Model' button on the job details page. Clicking this initiates a download of the trained model weights (simulated as a downloadable file or a link to cloud storage). UI also shows completed jobs and their final metrics.
    *   **Details:** For MVP, this could be a placeholder button or download a small dummy file. Actual large model file transfer is complex; focus on the UI/UX indication of completion and readiness for download.

**API & DATA FETCHING:**
-   **Authentication API:** Handled by NextAuth.js (e.g., `POST /api/auth/...`)
-   **Project API (`/api/projects`)**
    *   `GET /`: Fetch all projects for the logged-in user.
    *   `POST /`: Create a new project.
    *   `GET /[projectId]`: Fetch details for a specific project.
    *   `PUT /[projectId]`: Update a project.
    *   `DELETE /[projectId]`: Delete a project.
-   **Training Job API (`/api/training-jobs`)**
    *   `GET /?projectId=[projectId]`: Fetch all training jobs for a project.
    *   `POST /`: Start a new training job (takes project details and config).
    *   `GET /[jobId]`: Fetch details for a specific training job (including status).
    *   `GET /[jobId]/metrics`: Fetch historical metrics for a job (for initial load before SSE starts).
-   **Metrics Streaming (`/api/training-jobs/[jobId]/stream`)**
    *   Use Server-Sent Events (SSE) to stream new metrics from `trainingMetrics` table.
-   **Data Fetching:** Utilize Next.js `fetch` API within Server Components for initial data loads where possible. Use client-side fetching (e.g., `useEffect` with `fetch` or libraries like SWR/React Query) for dynamic data, form submissions, and real-time updates. Data validation using Zod on both client and server.

            *   Components: `ProjectDetailsCard`, `TrainingJobsTable`.
            *   Components: `StartTrainingJobButton` (opens modal).
        *   **`projects/[projectId]/jobs/[jobId]/page.tsx`**: Training Job Detail Page (Real-time monitoring dashboard, job configuration, results).
            *   Components: `JobStatusBadge`, `TrainingConfigView`, `LiveMetricsDashboard` (uses `MetricsChart` and `StatDisplay`), `ModelDownloadButton`.
        *   **`settings/page.tsx`**: User Settings (Profile info, API keys - future).

**UI/UX DESIGN & VISUAL IDENTITY:**
-   **Design Style:** Modern, clean, professional, with a subtle tech-forward feel. Focus on clarity and data visualization.
-   **Color Palette:**
    *   Primary: Deep Blue (`#1E3A8A` - Slate 800)
    *   Secondary: Teal (`#0694A2` - Emerald 500)
    *   Accent/Call to Action: Bright Purple (`#7C3AED` - Violet 600)
    *   Background: Dark Gray (`#1F2937` - Gray 800)
    *   Surface/Card Background: Slightly lighter Dark Gray (`#2D3748` - Gray 700)
    *   Text (Primary): Light Gray (`#E5E7EB` - Gray 200)
    *   Text (Secondary): Medium Gray (`#9CA3AF` - Gray 400)
    *   Success: Green (`#10B981` - Green 500)
    *   Error: Red (`#EF4444` - Red 500)
-   **Typography:** Sans-serif. Use Inter or similar modern font. Clear hierarchy using font weights and sizes.
-   **Layout:** Sidebar navigation on the left for authenticated app. Main content area takes up the rest of the space. Use a consistent grid system (e.g., 12-column). Cards for summaries and details. Clean forms with clear labels and validation feedback.
-   **Responsiveness:** Mobile-first approach. Sidebar collapses into a hamburger menu on smaller screens. Content reflows to fit screen width. Tables should be responsive (e.g., horizontal scroll or column hiding).

**ANIMATIONS:**
-   **Page Transitions:** Subtle fade-in/out using Next.js `transition` or a library like `Framer Motion` (optional for MVP).
-   **Hover Effects:** Slight scale-up or background color change on interactive elements (buttons, links, cards).
-   **Loading States:** Use `shadcn/ui` skeleton loaders or spinners (`LoadingSpinner.tsx`) while data is being fetched. Add shimmering effect to skeleton loaders.
-   **Micro-interactions:** Smooth transitions for expanding/collapsing sections, form submission feedback.
-   **Chart Animations:** Smooth animations for data updates and initial chart rendering.

**EDGE CASES & VALIDATIONS:**
-   **Authentication:** Redirect unauthenticated users to `/auth`. Protect all `/app` routes. Handle expired sessions gracefully.
-   **Empty States:** Display user-friendly messages and clear CTAs when projects list, job list, or monitoring data is empty (e.g., "No projects created yet. Click 'New Project' to start.").
-   **Form Validation:** Use Zod for robust schema validation on all user inputs (project names, training parameters, etc.). Provide clear, inline error messages.
-   **API Errors:** Implement centralized error handling. Display user-friendly error messages for API failures (e.g., "Failed to start training job. Please try again."). Log detailed errors on the server.
-   **Data Integrity:** Use database transactions where appropriate (e.g., creating a project and its initial job). Ensure foreign key constraints are used.
-   **Long-Running Operations:** Clearly indicate the status of training jobs ('queued', 'running', 'completed', 'failed'). Use SSE/WebSockets to ensure the monitoring dashboard reflects the latest status.
-   **Resource Limits:** (Future) Implement checks for subscription limits (GPU hours, storage).
