LTX Desktop is an open-source desktop application from Lightricks that runs the LTX-2.3 model — a 20.9B parameter multimodal model — entirely on your local GPU. Unlike cloud-based video generators, everything runs offline after the initial model download, with no per-generation fees and no data sent to external servers. The flagship capability is synchronized audio-video generation: feed LTX-2.3 an audio track and it generates visuals that move to the rhythm. Beyond generation, the app includes a proper non-linear editor with slip, slide, roll, and ripple trim tools; color correction; subtitle workflows with SRT import/export; and XML timeline exports compatible with Premiere Pro, DaVinci Resolve, and Final Cut Pro. It targets NVIDIA RTX cards with 8–12GB VRAM on Windows and Linux, with Apple Silicon support via API mode. LTX Desktop represents a meaningful step toward professional-grade AI video production that's free, local, and composable with existing workflows. For indie filmmakers and content creators who've been priced out of Runway or Sora subscriptions, this is a compelling alternative — especially as LTX-2.3's quality continues to close the gap with proprietary models.

trellis-mac is a community port of Microsoft's TRELLIS.2 image-to-3D model that runs entirely on Apple Silicon via PyTorch MPS — no NVIDIA GPU required. A single photo goes in, a 400,000-vertex mesh comes out in roughly 3.5 minutes on an M4 Pro, with no cloud dependencies. TRELLIS.2 is one of the strongest open-weights models for single-image 3D reconstruction, producing mesh quality that previously required either expensive NVIDIA hardware or cloud API calls. This port handles the MPS-specific tensor quirks and memory management that make running the model locally on Apple hardware nontrivial. The HN Show HN thread hit 84 points and generated active testing discussion, with multiple users confirming it runs as advertised on M1 Max and M2 Ultra hardware. For 3D artists, indie game developers, and VR/AR creators, the ability to generate production-quality meshes from reference photos on a MacBook is a meaningful workflow unlock. The bottleneck shifts from hardware access to the quality of your reference photography.
Reviewer scorecard
“The XML export to Premiere and DaVinci is what makes this production-ready. I can generate AI footage locally and drop it straight into a professional timeline without re-encoding. The offline-first architecture also means no API outages mid-project.”
“Solid port work — handling MPS tensor compatibility for a model this complex isn't trivial. The 3.5-minute generation time on M4 Pro is competitive and the 400K vertex output is actually usable for game assets without heavy retopology.”
“20GB model download, 8-12GB VRAM minimum, and the 720p quality ceiling still shows AI artifacts on fast motion. Mac users get routed to the API anyway, defeating the local-first promise. Wait for LTX-3 before betting a real project on this.”
“The original TRELLIS.2 still runs faster and with higher fidelity on a dedicated NVIDIA GPU. 3.5 minutes is fine for experimentation but too slow for iterative production workflows. Also, single-image 3D reconstruction still has consistency issues with complex objects.”
“Open-source, locally-run video generation with pro NLE integration is a category that didn't exist 18 months ago. LTX Desktop is the reference implementation — in 24 months this capability will be bundled into consumer editing apps by default.”
“This is Apple Silicon democratization in action. The fact that state-of-the-art 3D generation now runs on laptop hardware means 3D assets will be generated ad-hoc at every creative workflow stage within two years.”
“The audio-driven video generation is the feature I've been waiting for — I can score a short film and let the model generate matching visuals as a starting point. Not perfect, but the iteration speed on local hardware is 10x better than waiting on cloud queues.”
“As a 3D artist, being able to photo-scan real objects on my Mac without a render farm or API is a genuine workflow breakthrough. The mesh quality from TRELLIS.2 is good enough to use as a base for sculpting and texturing.”
