Show HN: TRELLIS.2 image-to-3D running on Mac Silicon – no Nvidia GPU needed

I ported Microsoft's TRELLIS.2 (4B parameter image-to-3D model) to run on Apple Silicon via PyTorch MPS. The original requires CUDA with flash_attn, nvdiffrast, and custom sparse convolution kernels: none of which work on Mac.

I replaced the CUDA-specific ops with pure-PyTorch alternatives: a gather-scatter sparse 3D convolution, SDPA attention for sparse transformers, and a Python-based mesh extraction replacing CUDA hashmap operations. Total changes are a few hundred lines across 9 files.

Generates ~400K vertex meshes from single photos in about 3.5 minutes on M4 Pro (24GB). Not as fast as H100 (where it takes seconds), but it works offline with no cloud dependency.

OpenAI’s existential questions

On the latest episode of Equity, we discuss OpenAI's latest acquisitions and whether they address "two big existential problems" for the company.

Blue Origin successfully reused its New Glenn rocket

Today's launch of AST SpaceMobile's BlueBird 7 satellite aboard Blue Origin's reusable New Glenn rocket was a partial success. The New Glenn touched down on its landing pad without incident, making it the second launch and landing for the first stage booster, and officially giving Jeff Bezos a reusable launch vehicle. Unfortunately for AST SpaceMobile, […]

Cloud development platform Vercel was hacked

A person claiming to be a member of ShinyHunters, which was behind the recent hack of Rockstar Games, posted some data online, including employee names, email addresses, and activity time stamps.
