Apr 1, 2025April 2025: Delivered RWKV7 deployment and generation-mode enhancements for sophgo/LLM-TPU, enabling RWKV7 on BM1684X with model compilation, ONNX export, C++ deployment, and a Python inference demo. Implemented generation-mode improvements via lmhead_with_topk to align top-k sampling with existing generation logic. Improved runtime robustness through fixes to configuration/tokenizer path resolution and an updated runtime library (libbmrt.so.1.0) to address stability. These changes increased production readiness, reduced deployment risk, and laid groundwork for scalable RWKV7 deployment on target hardware.
