Imagination Studio 4.3.1: Support for Up to Four Local NVIDIA GPUs and 96 GB on Mac

Imagination Studio 4.3.1 has been released — an update to the video generation tool Imagination-Studio-by-keys-Wasserman. The release dated 10.30.2026 was published on GitHub. The main change is support for up to four local NVIDIA GPUs on a single Linux machine: Studio runs on one card, while workers run on the remaining compute cards. The second change is that the default installation on Mac now requires 96 GB of memory instead of 64 GB.

What it means

In our reference, Imagination-Studio-by-keys-Wasserman lists the Metal platform — Apple-silicon Mac and NVIDIA DGX Spark. The new release expands on that description: it now claims operation on a single Linux machine with one to four local NVIDIA GPUs. In the tool's fact sheet, VRAM as described by the author is 8.3 GB, and system RAM is 128 GB for DGX Spark. For Mac, the memory requirement has changed: 96 GB for the default installation, while the images-only variant still requires 48 GB. The code license is Apache-2.0. The Drama 3 model weights are distributed under the Fish Audio Community License: research, non-commercial use, and commercial use with annual revenue under 500,000 USD are permitted; hosted speech generation services require a separate license. The largest weights file is 3.5 GB, and all files total 38.6 GB. The update primarily affects those running Studio on Linux workstations with multiple NVIDIA GPUs: workers are bound to cards by UUID, jobs with insufficient memory are rejected immediately, and a fifth card is not supported. For Mac users there is one change — the higher memory threshold for the default installation.
