# ZDTaichu5.0-9B-DSpark

A DSpark speculative-decoding draft model for ZDTaichu5.0-9B target models, trained with [speculators](https://github.com/vllm-project/speculators) and served with [vllm](https://github.com/vllm-project/vllm), primarily intended for multimodal scenarios.

## Performance Evaluation of DSpark

Acceptance length and speedup evaluation of DSpark across diverse multimodal benchmarks.
- Sampling: thinking enabled, temperature 1.0
- Speedup: evaluation on a single NVIDIA H800 GPU with a concurrency of 1
