Cosyvoice2-0.5B (https://github.com/FunAudioLLM/CosyVoice/blob/main/cosyvoice/vllm/cosyvoice2.py#L93) is a TTS model finetuned on top of the Qwen2-0.5B model, with an extra bias tensor on the decoder head.
This change allows this bias tensor to be loaded for better quality when running Cosyvoice2 in llama.cpp.
