In plain English: TRELLIS
Apple-Silicon-native launches dominated today's Show HN wave. @shivampkumar's TRELLIS.2 Mac port leads at 194 points; @teamchong's Prompt-to-Excalidraw running Gemma-4 E2B inside a 3.1GB browser sandbox hits 152; @ragojose's Shader Lab holds 155. Three distinct wedges — on-device 3D generation, browser-side LLM agents, GPU tooling — all shipped by individual makers.
In plain English: TRELLIS.2-on-Metal is the shape worth copying. @antirez notes Metal shaders could outpace CUDA for this workload once the MPS graph compiler matures — the port turns an "Nvidia-required" capability into "runs on my M3 Max." @gondar flags meshy.ai as the hosted competitor at $20–60/month; TRELLIS.2-on-device is the $0 alternative with a legitimate $9 "export unlimited models" wedge.
Find one ML model with real commercial value that requires CUDA (TRELLIS.2 for 3D, whisper-large-v4 for audio, SAM 3 for segmentation), port to MLX/Metal, charge $9–19 one-time. The port is the moat.
Apple usually ships a first-party MLX version within 12–18 months, and when Apple's repo absorbs the use case your paid version is dead.
