What's New in onLM

1.4.2

May 11, 2026

- 12 GB iPhone stability — capped MLX buffer pool at 20 MB; added per-model KV-cache quantization and output-token caps (Qwen 3.5 9B, Gemma 3/4, Llama 3.1, Mistral) to stop jetsam kills by turn 3. - Image generation — fixed OOM on 12 GB iPhones (proper hw.memsize gating, quantized SDXL path) and fixed a crash on long or non-Latin prompts (CLIP token sequences now clamped to 77). - Onboarding — Skip button on the final page once any chat-capable model is ready; downloads keep running in the background. - Download banner — now shown across all tabs, not just Chat.

Отличное приложение для запуска локальных LLM

По мне это лучшее из того, что попадалось для запуска локальных LLM. Первые версии крэшились на моем IPhone 17 pro max, но сейчас работает стабильно и транскрибация и текстовые запросы и даже генерация картинок. Интересно было бы добавить голосовой чат и приложение CarPlay, ну и какую нибудь локальную базу знаний ,чтобы решать специфичные задачи в условиях отсутствия интернета
