SpecBundle is an open-source initiative, jointly driven by the community and industry, to democratize speculative decoding by providing high-performance speculative decoding draft weights for mainstream open-source models.

This checkpoint was trained by the SpecForge Team and released as the phase 1 of SpecBundle release. We regenerated the responses in the OpenCoder-LLM/opc-sft-stage1 and trained the model on 1.4M data samples for 2 epochs. This checkpoint was trained using the SpecForge framework.
