LocalAI Bench is an on-device benchmark app that runs AI models directly on your iPhone and measures their performance and capabilities. All inference happens inside your device β your conversations and personal data never leave it. β On-Device Execution - Download open AI models (Llama, Qwen, Gemma, Phi, and more) and run them right on your device - Works fully offline once a model is downloaded β Real-Time Performance Metrics - Generation speed (tok/s), time-to-first-token (TTFT), peak memory (RAM), and thermal state β displayed live while you chat - Automated benchmark with a standard methodology: repeated measurements of text generation, prompt processing, translation, coding, and math speed β Capability Evaluation - Auto-graded tasks: math, coding, multilingual translation (KoreanβEnglish/Japanese/Chinese), summarization, reasoning, and vision - Compare capability, speed, and memory at a glance (choose 2-axis, composite, or efficiency scoring) β Vision & Speech Models - Vision: attach photos or recognize objects through the live camera - Speech: compare Whisper (tiny/base/small) transcription speed (RTF) β Compare & Manage Models - A/B head-to-head between two models, stress tests (thermal throttling curve) - Search models by capability (vision, coding, reasoning) or vendor and add them, with automatic iOS compatibility checks β Web Search (optional) - When enabled, fetches Wikipedia references for the model β ask about recent events - Inference stays 100% on-device; automatically skipped when offline Pure on-device AI β no cloud APIs, no fees, no subscriptions. Runnable models depend on your device's performance; larger models are recommended for devices with more memory.
