Model Playground: Private, Local AI

Unleash the power of Large Language Models (LLMs) directly on your device. 100% Private. 100% Offline.

Model Playground is the ultimate sandbox for AI enthusiasts, developers, and privacy-conscious users who want to explore Generative AI without relying on cloud-based servers. By running models locally, your data never leaves your phone, ensuring total privacy and zero subscription costs.

🛡️ Privacy Without Compromise
Most AI apps send your conversations to the cloud. Model Playground is different. It uses a "Privacy-by-Design" architecture where inference, chat history, and prompt processing happen exclusively on your device’s hardware. No internet is required to chat.

🚀 Dual-Engine Performance
Experience industry-leading flexibility with support for multiple high-performance inference engines:
- llama.cpp (GGUF): Run a vast library of community-quantized models with optimized performance for ARM64 architecture.
- MediaPipe LLM Inference: Leverage Google’s optimized runtime for high-speed execution of models like Gemma.

📥 Discover & Download
Not sure where to start? Browse our curated Discover catalog to find mobile-optimized models vetted for performance and quality.
- One-Tap Download: Easily fetch models like Llama 3.2, Gemma 2, Qwen, and Phi-3.
- Integrity Verified: Every download is checked against SHA-256 checksums to ensure file safety and accuracy.

🛠️ The Ultimate Developer Sandbox
Model Playground gives you full control over the "brain" of the AI:
- Local Import: Have a specific model? Import any .gguf or .task file directly from your local storage.
- Fine-Tune Parameters: Adjust Temperature, Top-P, and Max Tokens to see how they affect creativity and logic.
- System Prompts: Define the AI’s personality and constraints with custom system instructions.
- Benchmarking & Diagnostics: Monitor first-token latency, tokens-per-second, and memory usage with real-time performance metrics.

✨ Key Features:
- Conversational History: Seamlessly manage multiple chat threads.
- Voice & TTS: Integrated speech-to-text and multilingual text-to-speech for hands-free interaction.
- Clean UI: A modern, Material 3 interface with Dark Mode support.
- Transparency: A dedicated Diagnostics screen shows you exactly how much RAM and CPU the AI is using.

📋 Technical Compatibility:
- Format Support: GGUF (v2/v3) and MediaPipe .task bundles.
- Optimized for: arm64-v8a devices.
- Recommended: 6GB+ RAM for 3B parameter models; 8GB+ for 7B+ parameters.
