ModelStack
OpenAI's model behavior specification, organized around five core values including fidelity to human intent, harm reduction, and respect for autonomy, and paired with a layered monitoring system that captures model misalignment and overreach.
Timeline (last 90 days)
DeepSeek Harness can be deployed on a less powerful laptop as the "brain," while ModelStack is deployed on a high-performance machine as the "hands and feet," with the two machines collaborating over a local area network.
ModelStack implements asset lineage management, enabling traceability of the prompt, model, parameters (such as sampling steps, CFG scale, and random seed), and subsequent citations for every image.
The Harness + ModelStack combination can run more than ten AI applications locally, including text-to-image, image-to-video, text-to-speech, background removal, and image upscaling.
During text-to-video generation, the system performs video dimension alignment—for example, aligning 400×400 to a multiple of 32 to meet the input requirements of the generation model.
ModelStack provides multiple preset voice tones, and users can switch between male and female voices during text-to-speech.
During audio-to-text transcription, the system first uploads the local audio file to the asset library of the machine running ModelStack before invoking the transcription capability, because the remote machine cannot directly access local files.
ModelStack is a localized audio-visual generation tool that provides structured tool interfaces for Harness via MCP.
After disabling ModelStack's local area network access, Harness immediately loses its local audio-visual generation capability and instead attempts to scrape images from free websites or simulate video using FFmpeg.
Configuring Harness on a Mac requires entering the IP address and port of the remote ModelStack machine in the profile/web directory of the hidden .dsh folder under the user's home directory.
ModelStack has a built-in model marketplace where users can directly download document parsing models, the Qwen 3.8 series, MiniMax, and other models.
