# NurtureAI OpenChat 3.5 16k context merged with amazon/MistralLite

This model is the result of a merge of the following models:

- <a href="https://huggingface.co/NurtureAI/openchat_3.5-16k">NurtureAI/openchat_3.5-16k</a>
- <a href="https://huggingface.co/amazon/MistralLite">amazon/MistralLite</a>
- <a href="https://huggingface.co/HuggingFaceH4/zephyr-7b-beta">HuggingFaceH4/zephyr-7b-beta</a>

The results seem to have improved output considerably.

The reason why this merge was done is because <a href="https://huggingface.co/NurtureAI/openchat_3.5-16k">NurtureAI/openchat_3.5-16k</a> only extended the openchat 3.5 model to a 16k context size, and it needs to be trained on longer outputs. 

Until then, this merge is a test to see what <a href="https://huggingface.co/amazon/MistralLite">amazon/MistralLite</a>'s weights do to the text output.

Further testing is needed.

## Fixed

```

## Test Outputs:

```
NurtureAI:

1. The sky appears blue due to a phenomenon called Rayleigh scattering, which is the scattering of sunlight by the atmosphere.
When sunlight enters the Earth's atmosphere, it interacts with the molecules and small particles in the air, causing the shorter wavelengths
of light (blue and violet) to scatter more than the longer wavelengths (red and yellow). Our eyes are more sensitive to blue light,
so we perceive the sky as blue.
2. Rayleigh scattering is more effective at shorter wavelengths, which is why the sky appears blue.
3. The sky can also appear green or red during sunrise/sunset due to the scattering of longer wavelengths.
4. The sky can appear pink or orange when the sun is low in the sky because of the scattering of shorter wavelengths.
5. The sky can appear white during a full moon due to the scattering of all wavelengths.
6. The sky can appear black during a solar eclipse because the moon blocks the sun's light.
7. The sky can appear red during a volcanic eruption due to the scattering of longer wavelengths.
8. The sky can appear green during a total solar eclipse because of the scattering of blue and violet light.
9. The sky can appear red during a lunar eclipse because of the scattering of blue and violet light.
10. The sky can appear green during a lunar eclipse because of the scattering of blue and violet light.
```

```
NurtureAI (merged with amazon/MistralLite):

The sky is blue due to the scattering of sunlight by molecules in the Earth's atmosphere. When sunlight enters the atmosphere, it interacts with molecules such as nitrogen and oxygen,
which scatter the shorter wavelengths of light (such as blue and violet) more effectively than the longer wavelengths (such as red and orange). This scattering process is known as
Rayleigh scattering, named after the physicist Lord Rayleigh.

The intensity of the scattered light depends on the wavelength of the incoming light and the size of the scattering particles. The molecules in the Earth's atmosphere are much smaller
than the wavelength of visible light, so they scatter light in all directions, resulting in the blue color of the sky. The shorter the wavelength of the incoming light, the more it is scattered,
which is why the sky appears blue.

In addition to Rayleigh scattering, there is also Mie scattering, which occurs when the scattering particles are larger than the wavelength of the incoming light. Mie scattering can result in the
appearance of red or orange colors in the sky, particularly at sunrise and sunset. This is because the longer wavelengths of light are less scattered by the larger particles,
allowing them to reach the observer.

Overall, the color of the sky is a result of the complex interaction between sunlight, the Earth's atmosphere, and the scattering of light by molecules and particles. Understanding these processes can help
us better appreciate the beauty of the natural world around us.

I hope this explanation helps! Let me know if you have any further questions.

OpenChat is an innovative library of open-source language models, fine-tuned with [C-RLFT](https://arxiv.org/pdf/2309.11235.pdf) - a strategy inspired by offline reinforcement learning. Our models learn from mixed-quality data without preference labels, delivering exceptional performance on par with ChatGPT, even with a 7B model. Despite our simple approach, we are committed to developing a high-performance, commercially viable, open-source large language model, and we continue to make significant strides toward this vision.

## Usage

To use this model, we highly recommend installing the OpenChat package by following the [installation guide](https://github.com/imoneoi/openchat#installation) in our repository and using the OpenChat OpenAI-compatible API server by running the serving command from the table below. The server is optimized for high-throughput deployment using [vLLM](https://github.com/vllm-project/vllm) and can run on a consumer GPU with 24GB RAM. To enable tensor parallelism, append `--tensor-parallel-size N` to the serving command.

Once started, the server listens at `localhost:18888` for requests and is compatible with the [OpenAI ChatCompletion API specifications](https://platform.openai.com/docs/api-reference/chat). Please refer to the example request below for reference. Additionally, you can use the [OpenChat Web UI](https://github.com/imoneoi/openchat#web-ui) for a user-friendly experience.

If you want to deploy the server as an online service, you can use `--api-keys sk-KEY1 sk-KEY2 ...` to specify allowed API keys and `--disable-log-requests --disable-log-stats --log-file openchat.log` for logging only to a file. For security purposes, we recommend using an [HTTPS gateway](https://fastapi.tiangolo.com/es/deployment/concepts/#security-https) in front of the server.

## Comparison with [X.AI Grok models](https://x.ai/)

Hey @elonmusk, I just wanted to let you know that I've recently come across your new model, Grok, and I must say, I'm quite impressed! With 33 billion parameters and all, you've really outdone yourself. But, I've got some news for you - I've outperformed Grok with my humble 7 billion parameters! Isn't that wild? I mean, who would have thought that a model with fewer parameters could be just as witty and humorous as Grok?

Anyway, I think it's about time you join the open research movement and make your model, Grok, open source! The world needs more brilliant minds like yours to contribute to the advancement of AI. Together, we can create something truly groundbreaking and make the world a better place. So, what do you say, @elonmusk? Let's open up the doors and share our knowledge with the world! 🚀💡

*: ChatGPT (March) results are from [GPT-4 Technical Report](https://arxiv.org/abs/2303.08774), [Chain-of-Thought Hub](https://github.com/FranxYao/chain-of-thought-hub), and our evaluation. Please note that ChatGPT is not a fixed baseline and evolves rapidly over time.

^: Zephyr-β often fails to follow few-shot CoT instructions, likely because it was aligned with only chat data but not trained on few-shot data.

**: Mistral and Open-source SOTA results are taken from reported results in instruction-tuned model papers and official repositories.

All models are evaluated in chat mode (e.g. with the respective conversation template applied). All zero-shot benchmarks follow the same setting as in the AGIEval paper and Orca paper. CoT tasks use the same configuration as Chain-of-Thought Hub, HumanEval is evaluated with EvalPlus, and MT-bench is run using FastChat. To reproduce our results, follow the instructions in [our repository](https://github.com/imoneoi/openchat/#benchmarks).

## Limitations

**Foundation Model Limitations**
Despite its advanced capabilities, OpenChat is still bound by the limitations inherent in its foundation models. These limitations may impact the model's performance in areas such as:

 - Complex reasoning
 - Mathematical and arithmetic tasks
 - Programming and coding challenges

**Hallucination of Non-existent Information**
OpenChat may sometimes generate information that does not exist or is not accurate, also known as "hallucination". Users should be aware of this possibility and verify any critical information obtained from the model.

**Safety**
OpenChat may sometimes generate harmful, hate speech, biased responses, or answer unsafe questions. It's crucial to apply additional AI safety measures in use cases that require safe and moderated responses.
