"""<h1><center>MosaicML MPT-7B-Instruct</center></h1>
This demo is of [MPT-7B-Instruct](https://huggingface.co/mosaicml/mpt-7b-instruct). It is based on [MPT-7B](https://huggingface.co/mosaicml/mpt-7b) fine-tuned with approximately [60,000 instruction demonstrations](https://huggingface.co/datasets/sam-mosaic/dolly_hhrlhf)
If you're interested in [training](https://www.mosaicml.com/training) and [deploying](https://www.mosaicml.com/inference) your own MPT or LLMs, [sign up](https://forms.mosaicml.com/demo?utm_source=huggingface&utm_medium=referral&utm_campaign=mpt-7b) for MosaicML platform.
This is running on a smaller, shared GPU, so it may take a few seconds to respond. If you want to run it on your own GPU, you can [download the model from HuggingFace](https://huggingface.co/mosaicml/mpt-7b-instruct) and run it locally. Or [Duplicate the Space](https://huggingface.co/spaces/mosaicml/mpt-7b-instruct?duplicate=true) to skip the queue and run in a private space."""
