+# QuantFactory/DiarizationLM-8b-Fisher-v1-GGUF
+This is quantized version of [google/DiarizationLM-8b-Fisher-v1](https://huggingface.co/google/DiarizationLM-8b-Fisher-v1) created using llama.cpp
+
+# Original Model Card
+
+
+**This is not an officially supported Google product.**
+
+## Overview
+
+Note: This model is outdated. Please use [google/DiarizationLM-8b-Fisher-v2](https://huggingface.co/google/DiarizationLM-8b-Fisher-v2) instead.
+
+[DiarizationLM](https://arxiv.org/abs/2401.03506) model finetuned
+on the training subset of the Fisher corpus.
+
+* Foundation model: [unsloth/llama-3-8b-bnb-4bit](https://huggingface.co/unsloth/llama-3-8b-bnb-4bit)
+* Finetuning scripts: https://github.com/google/speaker-id/tree/master/DiarizationLM/unsloth
+
+## Training config
+
+This model is finetuned on the training subset of the Fisher corpus, using a LoRA adapter of rank 256. The total number of training parameters is 671,088,640. With a batch size of 16, this model has been trained for 25400 steps, which is ~8 epochs of the training data.
+
+We use the `mixed` flavor during our training, meaning we combine data from `hyp2ora` and `deg2ref` flavors. After the prompt builder, we have a total of 51,063 prompt-completion pairs in our training set.
+
+The finetuning took more than 4 days on a Google Cloud VM instance that has one NVIDIA A100 GPU with 80GB memory.
+
+The maximal length of the prompt to this model is 6000 characters, including the " --> " suffix. The maximal sequence length is 4096 tokens.

+
+## Usage
+
+First, you need to install two packages:
+
+```
+pip install transformers diarizationlm
+```
+
+On a machine with GPU and CUDA, you can use the model by running the following script:
+
+```python
+from transformers import LlamaForCausalLM, AutoTokenizer
+from diarizationlm import utils
+
+HYPOTHESIS = """<speaker:1> Hello, how are you doing <speaker:2> today? I am doing well. What about <speaker:1> you? I'm doing well, too. Thank you."""
+
+print("Loading model...")
+tokenizer = AutoTokenizer.from_pretrained("google/DiarizationLM-8b-Fisher-v1", device_map="cuda")
+model = LlamaForCausalLM.from_pretrained("google/DiarizationLM-8b-Fisher-v1", device_map="cuda")
+
+print("Tokenizing input...")
+inputs = tokenizer([HYPOTHESIS + " --> "], return_tensors = "pt").to("cuda")
+
+print("Generating completion...")
+outputs = model.generate(**inputs,
+                         max_new_tokens = inputs.input_ids.shape[1] * 1.2,
+                         use_cache = False)
+
+print("Decoding completion...")
+completion = tokenizer.batch_decode(outputs[:, inputs.input_ids.shape[1]:],
+                                    skip_special_tokens = True)[0]
+
+print("Transferring completion to hypothesis text...")
+transferred_completion = utils.transfer_llm_completion(completion, HYPOTHESIS)
+
+print("========================================")
+print("Hypothesis:", HYPOTHESIS)
+print("========================================")
+print("Completion:", completion)
+print("========================================")
+print("Transferred completion:", transferred_completion)
+print("========================================")
+```
+
+The output will look like below:

+```
