<p><h1>🐋 The Second OpenOrca Model Preview! 🐋</h1></p>
# OpenOrca x OpenChat - Preview2 - 13B
We have used our own [OpenOrca dataset](https://huggingface.co/datasets/Open-Orca/OpenOrca) to fine-tune Llama2-13B using [OpenChat](https://huggingface.co/openchat) packing and conditional behavior cloning.
This dataset is our attempt to reproduce the dataset generated for Microsoft Research's [Orca Paper](https://arxiv.org/abs/2306.02707).
This second preview release is trained on a curated filtered subset of most of our GPT4 augmented data.
This release highlights that our dataset and training methods have surpassed performance parity with the Orca paper.
We measured this with BigBench-Hard and AGIEval results with the same methods as used in the Orca paper, finding ~103% of original Orca's performance on average.
As well, this is done with ~1/10th the compute requirement and using <20% of the dataset size from the original Orca paper.
We have run extensive evaluations internally and expect this model to place number 1 on both the HuggingFaceH4 Open LLM Leaderboard and the GPT4ALL Leaderboard for 13B models.
"One" of [OpenChat](https://huggingface.co/openchat) has joined our team, and we'd like to provide special thanks for their training of this model!
We have utilized OpenChat conditional behavior cloning and [MultiPack algorithm](https://github.com/imoneoi/multipack_sampler) which achieves 99.85% bin-packing efficiency on our dataset.
This has significantly reduced training time, with efficiency improvement of 3-10X over traditional methods.

We are in-process with training more models, so keep a look out on our org for releases coming soon with exciting partners.
We will also give sneak-peak announcements on our Discord, which you can find here:

# Evaluation
We have evaluated **OpenOrcaxOpenChat-Preview2-13B** on hard reasoning tasks from BigBench-Hard and AGIEval as outlined in the Orca paper.
Our average performance for BigBench-Hard: 0.488
Average for AGIEval: 0.441
In the Orca paper, they measured their score relative to Vicuna on these evals.
We've done the same and have found our score averages to >103% of the total improvement that was shown in the Orca paper, using the same evaluation methods as outlined in the paper.
So we are surpassing Orca performance with <20% of the dataset size and ~1/10th the training budget!
## BigBench-Hard Performance
## AGIEval Performance
## HuggingFaceH4 Open LLM Leaderboard Performance
We have run our own tests using parameters matching the [HuggingFaceH4 Open LLM Leaderboard](https://huggingface.co/spaces/HuggingFaceH4/open_llm_leaderboard) evals.
We find
## GPT4ALL Leaderboard Performance
We have tested using parameters matching the GPT4ALL Benchmark Suite and report our results and placement vs their official reporting below.
We place #1 for all open models and come within comparison of text-davinci-003, a proprietary model an order of magnitude larger.
# Dataset
We used a curated, filtered selection of most of the GPT-4 augmented data from our OpenOrca dataset, which aims to reproduce the Orca Research Paper dataset.
Further details of our curation practices will be forthcoming with our full model release.
# Training
We trained with 8x A100-80G GPUs for 46 hours, completing 5 epochs of full fine tuning on our dataset.
This contrasts with the 20x A100-80G GPUs for 200 hours used in the Orca paper, for only 3 epochs.
Our compute requirement was <1/10th that of the original Orca.
Commodity cost was ~$600.
Please await our full releases for further training details.
# Prompt Template
We use our own prompt template which we call "`OpenChat Llama2 V1`"
Examples:
```
# Single-turn V1 Llama 2
tokenize("User: Hello<|end_of_turn|>Assistant:")
# Result: [1, 4911, 29901, 15043, 32000, 4007, 22137, 29901]
# Multi-turn V1 Llama 2
tokenize("User: Hello<|end_of_turn|>Assistant: Hi<|end_of_turn|>User: How are you today?<|end_of_turn|>Assistant:")
# Result: [1, 4911, 29901, 15043, 32000, 4007, 22137, 29901, 6324, 32000, 4911, 29901, 1128, 526, 366, 9826, 29973, 32000, 4007, 22137, 29901]
```
# Serving
This model is most easily served with [OpenChat's](https://github.com/imoneoi/openchat) customized vLLM OpenAI-compatible API server.
This is highly recommended as it is by far the fastest in terms of inference speed and is a quick and easy option for setup.
We also illustrate setup of Oobabooga/text-generation-webui below. The settings outlined there will also apply to other uses of `Transformers`.
## Serving with OpenChat
[Install OpenChat](https://github.com/imoneoi/openchat/#installation)
After installation, run:
```bash
python -m ochat.serving.openai_api_server \
--model-type openchat_llama2 \
--model Open-Orca/OpenOrcaxOpenChat-Preview2-13B \
--engine-use-ray --worker-use-ray --max-num-batched-tokens 5120
```
Follow the OpenChat documentation to use features such as tensor parallelism on consumer GPUs, API keys, and logging.
You may then connect to the OpenAI-compatible API endpoint with tools such as [BetterGPT.chat](https://bettergpt.chat).
## Serving with Oobabooga / text-generation-webui
The model may also be loaded via [oobabooga/text-generation-webui](https://github.com/oobabooga/text-generation-webui/) in a similar manner to other models.
See the requirements below. Note that inference with Transformers is significantly slower than using the recommended OpenChat vLLM server.
### Oobabooga Key Requirements
* You will first need to download the model as you normally do to the "`models/`" folder of your `text-generation-webui` installation.
* To use the unquantized model presented here, select "`Transformers`"" in the webui's "`Model`" tab "`Model loader`" dropdown.
* You will likely want to tick "`auto-devices`". The model will require >40GB VRAM after loading in context for inference.
* The model was trained in bf16, so tick the "`bf16`" box for best performance.
* It will run safely on single GPUs with VRAM >=48GB (e.g. A6000)
* If using consumer GPUs, e.g. 2x RTX3090 24GB, you will likely want to enter "18,17" under "`tensor_split`" to split the model across both GPUs
* The model will perform significantly better if you use the appropriate prompting template
* We will submit a PR to include our prompting template into text-generation-webui soon
* For now, manually enter the settings described in the following sections:
### Oobabooga Chat Settings
In the "`Chat settings`" tab, select the following settings:
For "`User String`" ...
```
User:
```
For "`Bot string`" ...
```
Assistant:
```
For "`Context`", it is not necessary but we have found good results with ...
```
You are a helpful assistant. Please answer truthfully and write out your thinking step by step to be sure you get the right answer. If you make a mistake or encounter an error in your thinking, say so out loud and attempt to correct it. If you don't know or aren't sure about something, say so clearly. You will act as a professional logician, mathematician, and physicist. You will also act as the most appropriate type of expert to answer any particular question or solve the relevant problem; state which expert type your are, if so. Also think of any particular named expert that would be ideal to answer the relevant question or solve the relevant problem; name and act as them, if appropriate.
```
For "`Turn template`", this is absolutely essential to have. You will get poor, mixed up output without this template ...
```
<|user|> <|user-message|><|end_of_turn|>\n<|bot|> <|bot-message|>\n
```
When done, it should look as below:
<img src="https://huggingface.co/Open-Orca/OpenOrcaxOpenChat-Preview2-13B/resolve/main/Images/OpenOrcaLlama2OobaboogaChatInstructionTemplate.png" style="width: 40%">
You may then save this as a named template preset by clicking the "Floppy" icon and giving it an appropriate name in the popup, e.g. "`OpenOrcaxOpenChat Llama2`".
### Oobabooga Text Generation Mode
In the "`Text generation`" tab, select "`instruct`" as the mode:
#### Mode Illustration
It should look as below:
<img src="https://huggingface.co/Open-Orca/OpenOrcaxOpenChat-Preview2-13B/resolve/main/Images/OpenOrcaLlama2OobaboogaInstructMode.png" style="width: 40%">
Then you should be ready to generate!
