Peak Pocket AI

Peak Pocket AI is a lab for language models that run on your iPhone. Chat privately with open models, then look under the hood: how fast they generate, how confident they are in every word, and how your phone holds up under sustained load. PRIVATE BY DESIGN Models run on the device. Your chats, notebook, and settings never leave your iPhone. No account, no analytics, no ads. Once a model is downloaded, everything works in airplane mode. A LAB NOTEBOOK FOR EVERY GENERATION Every reply is recorded with its seed, settings, timings, and device state. Rerun any run with identical settings and see whether the output reproduces, character for character. Export runs as CSV or JSON. LIVE TELEMETRY Watch tokens per second, time to first token, memory, and thermal state as a reply streams in. SEE WHAT THE MODEL WAS THINKING Confidence coloring shows how sure the model was of each word. Tap any word to see the alternatives it nearly chose, with their probabilities. Run-level statistics include mean probability and perplexity. ENDURANCE TESTS Measure what sustained generation does to your phone: throughput over time, throttling, thermal state, and battery used per thousand tokens. Tests stop automatically at critical temperature or low battery. SIDE-BY-SIDE EXPERIMENTS Run the same prompt and seed across models or settings and compare speed, memory, and confidence. BRING YOUR OWN MODELS Browse Hugging Face for GGUF models with a fit estimate for your phone's memory, including gated models with your access token. Optionally connect an OpenAI-compatible provider with your own API key; remote chats are clearly marked. Built by Peak Summit Labs.
