## Summary

OpenBMB releases the DSpark draft head for MiniCPM-OCR 1.0, a speculative decoding model that proposes tokens for the 1.3B main model to verify, improving end-to-end processing efficiency by 55%. The release reaches about 1.49× the throughput of PaddleOCR-VL-1.6 and 3.62× that of MinerU2.5 Pro. The draft has 296,837,889 parameters, proposes 15 tokens per forward pass, and must be paired with the matching MiniCPM-OCR 1.0 checkpoint.
