Local LLM Playground

Local LLM Playground is an AI playground for running local language models directly on your iPhone. The app supports both GGUF and MLX language models, and now also supports Apple Foundation Models. From entering prompts to viewing inference results, you can easily experiment with on-device AI entirely on your device. The following AI models are bundled with the app, so you can start using local AI immediately after installation: * Qwen2.5-0.5B-Instruct-Q4_K_M (GGUF) * Qwen3-0.6B-MLX-4bit (MLX) No cloud connection or API key is required. All AI processing is performed locally on your device, and your prompts and personal data are never transmitted to external servers. In addition to prompt experimentation and model evaluation, the app provides detailed inference metrics, including: * Token generation speed (tokens/sec) * Inference time (prefill / decode) * Token usage statistics *…
