Phosphene 3.4.0 Brings MiniMax H3 Video Generation to Mac Locally

Phosphene 3.4.0 has been released, with developer @cocktailpeanut enabling local MiniMax H3 video generation on Apple Silicon Macs via the MLX framework, eliminating the need for cloud or API keys. This marks a rapid community effort to localize MiniMax H3 after its open-source release, offering a new offline option for high-end video generation.

Confirmed

• Version and model: Phosphene 3.4.0 adds MiniMax H3 as a second local video generation engine, alongside the existing LTX-2.3.
• Hardware requirement: Running MiniMax H3 locally requires a Mac with 64GB RAM.
• Features: Supports joint dialogue and sound generation in both text and image modes.
• Generation speed: According to the workbench log, generating a multimodal AI character video takes approximately 36 minutes.

Why it matters

This update breaks the absolute dependence on cloud computing for high-end video generation. Developer @cocktailpeanut, using the MLX framework, has brought the complete multimodal generation workflow, including sound and visuals, to the local environment, providing a viable solution for creators who prioritize privacy and offline workflows.
