The 'Unsloth AI (Daniel Han)' showcase highlighted the successful implementation of Gemma 2 from scratch using Numpy and Cupy, showcasing its ability to run on both GPU and CPU. Users can access Gemma 2 from scratch using Numpy and later port it to Cupy. The Cupy version requires a GPU with 24GB memory for optimal performance, but there is also a Cupy f16 version available for GPUs with less than 16GB memory. Additionally, users can run the implementation on CPU using the Numpy notebook, providing broader accessibility for those without powerful GPUs. This allows for testing and smaller scale computations that do not require extensive hardware resources.

Innovative CV Project for AOE2:

A member proposed a CV project to create AI assistants for Age of Empire II, focusing on decision-making strategies by mapping game assets using SAM and YOLO.

LLMs Struggle with Visual Object Recognition:

Concerns were raised about the limitations of state-of-the-art LLMs in recognizing objects accurately in images, noting their descriptive nature rather than precise object localization.

Mapping Game Assets to a Text Matrix:

The strategy involves downsizing the game screen into a text map representing key assets for improved counting and localization by LLMs.

Concerns on Single Snapshot Game Analysis:

Doubts were expressed on the strategy's effectiveness in deducing game strategy from a single snapshot, advocating for capturing dynamic game states.

Dynamic Updates or Game Injection Needed:

Suggestions included maintaining dynamic updates of text matrix or injecting real-time game data rather than relying solely on computer vision for comprehensive data capture.
