+## Provided files, and GPTQ parameters
+
+Multiple quantisation parameters are provided, to allow you to choose the best one for your hardware and requirements.
+
+Each separate quant is in a different branch.  See below for instructions on fetching from different branches.
+
+Most GPTQ files are made with AutoGPTQ. Mistral models are currently made with Transformers.
+
+<details>
+  <summary>Explanation of GPTQ parameters</summary>
+
+- Bits: The bit size of the quantised model.
+- GS: GPTQ group size. Higher numbers use less VRAM, but have lower quantisation accuracy. "None" is the lowest possible value.
+- Act Order: True or False. Also known as `desc_act`. True results in better quantisation accuracy. Some GPTQ clients have had issues with models that use Act Order plus Group Size, but this is generally resolved now.
+- Damp %: A GPTQ parameter that affects how samples are processed for quantisation. 0.01 is default, but 0.1 results in slightly better accuracy.
+- GPTQ dataset: The calibration dataset used during quantisation. Using a dataset more appropriate to the model's training can improve quantisation accuracy. Note that the GPTQ calibration dataset is not the same as the dataset used to train the model - please refer to the original model repo for details of the training dataset(s).
+- Sequence Length: The length of the dataset sequences used for quantisation. Ideally this is the same as the model sequence length. For some very long sequence models (16+K), a lower sequence length may have to be used. Note that a lower sequence length does not limit the sequence length of the quantised model. It only impacts the quantisation accuracy on longer inference sequences.
+- ExLlama Compatibility: Whether this file can be loaded with ExLlama, which currently only supports Llama and Mistral models in 4-bit.

+## How to download, including from branches
+
+### In text-generation-webui
+
+To download from the `main` branch, enter `TheBloke/Orca-2-13B-GPTQ` in the "Download model" box.
+
+To download from another branch, add `:branchname` to the end of the download name, eg `TheBloke/Orca-2-13B-GPTQ:gptq-4bit-32g-actorder_True`
+
+### From the command line
+
+I recommend using the `huggingface-hub` Python library:
+
+```shell
+pip3 install huggingface-hub
+```
+
+To download the `main` branch to a folder called `Orca-2-13B-GPTQ`:
+
+```shell
+mkdir Orca-2-13B-GPTQ
+huggingface-cli download TheBloke/Orca-2-13B-GPTQ --local-dir Orca-2-13B-GPTQ --local-dir-use-symlinks False
+```
+
+To download from a different branch, add the `--revision` parameter:
+
+```shell
+mkdir Orca-2-13B-GPTQ
+huggingface-cli download TheBloke/Orca-2-13B-GPTQ --revision gptq-4bit-32g-actorder_True --local-dir Orca-2-13B-GPTQ --local-dir-use-symlinks False
+```
+
+<details>
+  <summary>More advanced huggingface-cli download usage</summary>
+
+If you remove the `--local-dir-use-symlinks False` parameter, the files will instead be stored in the central Hugging Face cache directory (default location on Linux is: `~/.cache/huggingface`), and symlinks will be added to the specified `--local-dir`, pointing to their real location in the cache. This allows for interrupted downloads to be resumed, and allows you to quickly clone the repo to multiple places on disk without triggering a download again. The downside, and the reason why I don't list that as the default option, is that the files are then hidden away in a cache folder and it's harder to know where your disk space is being used, and to clear it up if/when you want to remove a download model.
+
+The cache location can be changed with the `HF_HOME` environment variable, and/or the `--cache-dir` parameter to `huggingface-cli`.
+
+For more documentation on downloading with `huggingface-cli`, please see: [HF -> Hub Python Library -> Download files -> Download from the CLI](https://huggingface.co/docs/huggingface_hub/guides/download#download-from-the-cli).
+
+To accelerate downloads on fast connections (1Gbit/s or higher), install `hf_transfer`:
+
+```shell
+pip3 install hf_transfer
+```
+
+And set environment variable `HF_HUB_ENABLE_HF_TRANSFER` to `1`:
+
+```shell
+mkdir Orca-2-13B-GPTQ
+HF_HUB_ENABLE_HF_TRANSFER=1 huggingface-cli download TheBloke/Orca-2-13B-GPTQ --local-dir Orca-2-13B-GPTQ --local-dir-use-symlinks False
+```
+
+Windows Command Line users: You can set the environment variable by running `set HF_HUB_ENABLE_HF_TRANSFER=1` before the download command.
+</details>
+
+### With `git` (**not** recommended)
+
+To clone a specific branch with `git`, use a command like this:
+
+```shell
+git clone --single-branch --branch gptq-4bit-32g-actorder_True https://huggingface.co/TheBloke/Orca-2-13B-GPTQ
+```
+
+Note that using Git with HF repos is strongly discouraged. It will be much slower than using `huggingface-hub`, and will use twice as much disk space as it has to store the model files twice (it stores every byte both in the intended target folder, and again in the `.git` folder as a blob.)

+## Python code example: inference from this GPTQ model
+
+### Install the necessary packages
+
+Requires: Transformers 4.33.0 or later, Optimum 1.12.0 or later, and AutoGPTQ 0.4.2 or later.
+
+```shell
+pip3 install --upgrade transformers optimum
+# If using PyTorch 2.1 + CUDA 12.x:
+pip3 install --upgrade auto-gptq
+# or, if using PyTorch 2.1 + CUDA 11.x:
+pip3 install --upgrade auto-gptq --extra-index-url https://huggingface.github.io/autogptq-index/whl/cu118/
+```
+
+If you are using PyTorch 2.0, you will need to install AutoGPTQ from source. Likewise if you have problems with the pre-built wheels, you should try building from source:
+
+```shell
+pip3 uninstall -y auto-gptq
+git clone https://github.com/PanQiWei/AutoGPTQ
+cd AutoGPTQ
+git checkout v0.5.1
+pip3 install .
+```
+
+### Example Python code
+
+```python
+from transformers import AutoModelForCausalLM, AutoTokenizer, pipeline
+
+model_name_or_path = "TheBloke/Orca-2-13B-GPTQ"
+# To use a different branch, change revision
+# For example: revision="gptq-4bit-32g-actorder_True"
+model = AutoModelForCausalLM.from_pretrained(model_name_or_path,

+# Original model card: Microsoft's Orca 2 13B
+
+
+# Orca 2
+
+<!-- Provide a quick summary of what the model is/does. -->
+
+Orca 2 is a helpful assistant that is built for research purposes only and provides a single turn response
+in tasks such as reasoning over user given data, reading comprehension, math problem solving and text summarization.
+The model is designed to excel particularly in reasoning.
+
+We open-source Orca 2 to encourage further research on the development, evaluation, and alignment of smaller LMs.
+
+## What is Orca 2’s intended use(s)?
+
++ Orca 2 is built for research purposes only.
++ The main purpose is to allow the research community to assess its abilities and to provide a foundation for
+building better frontier models.
+
+## How was Orca 2 evaluated?
+
++ Orca 2 has been evaluated on a large number of tasks ranging from reasoning to grounding and safety. Please refer
+to Section 6 and Appendix in the [Orca 2 paper](https://arxiv.org/pdf/2311.11045.pdf) for details on evaluations.
+
+## Model Details
+
+Orca 2 is a finetuned version of LLAMA-2. Orca 2’s training data is a synthetic dataset that was created to enhance the small model’s reasoning abilities. 
+All synthetic training data was moderated using the Microsoft Azure content filters. More details about the model can be found in the [Orca 2 paper](https://arxiv.org/pdf/2311.11045.pdf).
+
+Please refer to LLaMA-2 technical report for details on the model architecture.
+
+## License
+

+Llama 2 is licensed under the [LLAMA 2 Community License](https://ai.meta.com/llama/license/), Copyright © Meta Platforms, Inc. All Rights Reserved.
+
+## Bias, Risks, and Limitations
+
+Orca 2, built upon the LLaMA 2 model family, retains many of its limitations, as well as the
+common limitations of other large language models or limitation caused by its training process,
+including:
+
+**Data Biases**: Large language models, trained on extensive data, can inadvertently carry
+biases present in the source data. Consequently, the models may generate outputs that could
+be potentially biased or unfair.
+
+**Lack of Contextual Understanding**: Despite their impressive capabilities in language understanding and generation, these models exhibit limited real-world understanding, resulting
+in potential inaccuracies or nonsensical responses.
+
+**Lack of Transparency**: Due to the complexity and size, large language models can act
+as “black boxes”, making it difficult to comprehend the rationale behind specific outputs or
+decisions. We recommend reviewing transparency notes from Azure for more information.
+
+**Content Harms**: There are various types of content harms that large language models
+can cause. It is important to be aware of them when using these models, and to take
+actions to prevent them. It is recommended to leverage various content moderation services
+provided by different companies and institutions. On an important note, we hope for better
+regulations and standards from government and technology leaders around content harms
+for AI technologies in future. We value and acknowledge the important role that research
+and open source community can play in this direction.
+
+**Hallucination**: It is important to be aware and cautious not to entirely rely on a given
+language model for critical decisions or information that might have deep impact as it is
+not obvious how to prevent these models from fabricating content. Moreover, it is not clear
+whether small models may be more susceptible to hallucination in ungrounded generation
+use cases due to their smaller sizes and hence reduced memorization capacities. This is an
+active research topic and we hope there will be more rigorous measurement, understanding
+and mitigations around this topic.
+
+**Potential for Misuse**: Without suitable safeguards, there is a risk that these models could
+be maliciously used for generating disinformation or harmful content.
+
+**Data Distribution**: Orca 2’s performance is likely to correlate strongly with the distribution
+of the tuning data. This correlation might limit its accuracy in areas underrepresented in
+the training dataset such as math, coding, and reasoning.
+
+**System messages**: Orca 2 demonstrates variance in performance depending on the system
+instructions. Additionally, the stochasticity introduced by the model size may lead to
+generation of non-deterministic responses to different system instructions.
+
+**Zero-Shot Settings**: Orca 2 was trained on data that mostly simulate zero-shot settings.
+While the model demonstrate very strong performance in zero-shot settings, it does not show
+the same gains of using few-shot learning compared to other, specially larger, models.
+
+**Synthetic data**: As Orca 2 is trained on synthetic data, it could inherit both the advantages
+and shortcomings of the models and methods used for data generation. We posit that Orca
+2 benefits from the safety measures incorporated during training and safety guardrails (e.g.,
+content filter) within the Azure OpenAI API. However, detailed studies are required for
+better quantification of such risks.
+
+This model is solely designed for research settings, and its testing has only been carried
+out in such environments. It should not be used in downstream applications, as additional
+analysis is needed to assess potential harm or bias in the proposed application.

+## Getting started with Orca 2
+
+**Inference with Hugging Face library**
+
+```python
+import torch
+import transformers
+
+if torch.cuda.is_available():
+    torch.set_default_device("cuda")
+else:
+    torch.set_default_device("cpu")
+    
+model = transformers.AutoModelForCausalLM.from_pretrained("microsoft/Orca-2-13b", device_map='auto')
+
+# https://github.com/huggingface/transformers/issues/27132
+# please use the slow tokenizer since fast and slow tokenizer produces different tokens
+tokenizer = transformers.AutoTokenizer.from_pretrained(
+        "microsoft/Orca-2-13b",
+        use_fast=False,
+    )
+
+system_message = "You are Orca, an AI language model created by Microsoft. You are a cautious assistant. You carefully follow instructions. You are helpful and harmless and you follow ethical guidelines and promote positive behavior."
+user_message = "How can you determine if a restaurant is popular among locals or mainly attracts tourists, and why might this information be useful?"
+
+prompt = f"<|im_start|>system\n{system_message}<|im_end|>\n<|im_start|>user\n{user_message}<|im_end|>\n<|im_start|>assistant"
+
+inputs = tokenizer(prompt, return_tensors='pt')
+output_ids = model.generate(inputs["input_ids"],)
+answer = tokenizer.batch_decode(output_ids)[0]
+
+print(answer)
+
+# This example continues showing how to add a second turn message by the user to the conversation
+second_turn_user_message = "Give me a list of the key points of your first answer."
+
+# we set add_special_tokens=False because we dont want to automatically add a bos_token between messages
+second_turn_message_in_markup = f"\n<|im_start|>user\n{second_turn_user_message}<|im_end|>\n<|im_start|>assistant"
+second_turn_tokens = tokenizer(second_turn_message_in_markup, return_tensors='pt', add_special_tokens=False)
+second_turn_input = torch.cat([output_ids, second_turn_tokens['input_ids']], dim=1)
+
+output_ids_2 = model.generate(second_turn_input,)
+second_turn_answer = tokenizer.batch_decode(output_ids_2)[0]
+
+print(second_turn_answer)
+```
+
+
+**Safe inference with Azure AI Content Safety**
+
+The usage of [Azure AI Content Safety](https://azure.microsoft.com/en-us/products/ai-services/ai-content-safety/) on top of model prediction is strongly encouraged 
+and can help prevent content harms. Azure AI Content Safety is a content moderation platform
+that uses AI to keep your content safe. By integrating Orca 2 with Azure AI Content Safety, 
+we can moderate the model output by scanning it for sexual content, violence, hate, and 
+self-harm with multiple severity levels and multi-lingual detection. 
+
+```python
+import os
+import math
+import transformers
+import torch

+
+CONTENT_SAFETY_KEY = os.environ["CONTENT_SAFETY_KEY"]
+CONTENT_SAFETY_ENDPOINT = os.environ["CONTENT_SAFETY_ENDPOINT"]
+
+# We use Azure AI Content Safety to filter out any content that reaches "Medium" threshold
+# For more information: https://learn.microsoft.com/en-us/azure/ai-services/content-safety/
+def should_filter_out(input_text, threshold=4):
+    # Create an Content Safety client
+    client = ContentSafetyClient(CONTENT_SAFETY_ENDPOINT, AzureKeyCredential(CONTENT_SAFETY_KEY))

+    request = AnalyzeTextOptions(text=input_text)
+
