The author turned PP-OCRv6 into a local workstation and open-sourced it for free, supporting Mac CoreML acceleration, providing three models: Tiny/Small/Medium, with image upload, batch processing, and multiple export formats, running locally to protect privacy.
WaveRNN and FastSpeech2 models were discovered in the iOS 27 Simulator files, indicating their use for Siri's text-to-speech, alongside a logistic regression model for concert ranking.
This paper presents a systematic optimization study of real-time diffusion model inference on the Apple M3 Ultra, achieving 22.7 FPS at 512x512 resolution using CoreML conversion and a distillation model, revealing that CUDA-optimized techniques do not directly transfer to Apple's unified memory architecture.
