Product Positioning & Context

AI Executive Synthesis
The developers are failing to provide a clear, documented, and functional inference pipeline for their model, impacting usability and the ability for users to leverage its core functionality.
This issue exposes a critical gap in the 'Lance' model's usability: the absence of a clear mechanism for providing `prompt.json` during inference. Despite providing an `inference_lance.sh` script with various parameters for video generation, the fundamental input method for prompts is missing or undocumented. This directly impedes users from performing core text-to-video tasks, rendering the model's advanced capabilities inaccessible. For a 3B-parameter multimodal model, a functional and intuitive inference pipeline is non-negotiable for adoption and practical application. This indicates a significant oversight in developer experience and product completeness, hindering market utility.

> I see. No need to add flash-attn as dependency, just mention about it in Readme should be sufficient, since FA2 will need to be build from source first (which could take long), as some people might prefer to install a pre-built FA2 wheel from third-party.

Thanks for your interest and feedback. In our training and inference pipeline, Flash Attention is indeed treated as a required dependency. We will add it to the dependency list and clarify this in the README.
