The model
microsoft/BitNet-b1.58-2B-4Tuses the architecture stringBitNetForCausalLM(with a capital 'N'), but theconvert-hf-to-gguf-bitnet.pyscript expectedBitnetForCausalLM. Additionally, these newer models use BPE tokenization instead of SentencePiece, meaning they don't have atokenizer.modelfile. This PR adds the alias to the@Model.registerdecorator and adds the same tokenizer fallback logic thatLlamaModeluses so the conversion script can successfully process these models without throwing errors.
