# DeepSpec Decoding Lab

An interactive research dashboard for the DeepSeek-AI DeepSpec collection:
DSpark, DFlash, and EAGLE-3 draft modules across Qwen3 and Gemma4 targets.

The Space uses the DSpark paper's Table 1 accepted-length measurements, public
Hugging Face checkpoint metadata, and a deterministic speculative-decoding
simulator to make the collection easy to inspect without requiring a multi-GPU
serving stack.

The UI is tuned for dark-mode readability across Gradio controls, tables,
Plotly charts, and custom speculative-decoding visualizations.
