        """Bloom is a model made by research teams from [HuggingFace](https://huggingface.co/bigscience/bloom) and world over (more than 1000 researchers coming together and working as [BigScienceW Bloom](https://twitter.com/BigscienceW)).Large language models can produce coherent sentences but can they produce **Humor** too? Yes, they can, given the correct prompt (And Yes, Prompt Engineering 🤖 should definitely become a thing by now).\n\n**How to Use this App**: Just Fire Away the Generate Meme button below, as many times as you want!! If you see repeated or similar memes getting generated in consecutive runs, toggle temperature and top_p values.\n\n**How this App works**: Figuring out the right set of Prompting + Writing on an Image + Bit of engineering. Currently, Bloom's Public API has size-limits on Token-Generation, so you can get only few tokens generated at a time.\n\n<pre>                              Bloom generating very few tokens                    When Few words are Enough</pre>\n\n<pre><span style='font-size:30px'>                                🤝Memes</span></pre>\n\nIt is a fun little App which you can play with for a while.This Space is created by [Yuvraj Sharma](https://twitter.com/yvrjsharma)"""
