InstructMesh (MIT/CSAIL) enables interactive repair and fabrication of AI-generated 3D models

Researchers at MIT CSAIL, Google, and Northeastern unveiled InstructMesh, an interface that pairs Microsoft’s TRELLIS 3D generator with GPT-4 to let users highlight and iteratively repair AI-generated 3D meshes before 3D printing. In tests using Thingiverse models, TRELLIS produced structural flaws in ~80% of cases, and novice users successfully identified and fixed problems about 90% of the time as judged by experts; the team fabricated functional prototypes (mugs, glasses, a knee brace, and simple robots) and is exploring AR integration.

MIT Transit Lab to develop PTIQ AI platform for public transit with $2.1M Google.org grant

Google.org awarded $2.1 million to MIT Transit Lab to fund a three-year project called the Public Transit Intelligence Hub (PTIQ), a centralized AI-orchestrated platform to unify transit agencies’ real-time monitoring, operations control, and passenger communications; Google.org will also provide pro bono engineering and AI product support. PTIQ plans to integrate predictive models, optimization engines and large-language-model based contextual reasoning into a decision‑support interface for control-center staff, leaving final operational decisions to human operators.
