Gemini Executive Synthesis
The Lance model's inference capability, specifically the mechanism for providing input prompts (e.g., `prompt.json`) for tasks like text-to-video generation.
Technical Positioning
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.
SaaS Insight & Market Implications
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.

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 ...
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...
