Reported by Dev.to Machine Learning: Adding GPU backends to a pure-C TTS engine: Metal, CUDA, and the rented-Mac trick. Analysis and context written by TickrWire.

30-second summary

How we bolted opt-in Apple Metal and NVIDIA CUDA backends onto a pure-C Qwen3-TTS engine, resident fused pipelines, server request-batching, and measuring it all on a Mac mini M2 rented by the hour. Plus the two 'obvious' optimizations we killed with data.
