"""The following is a conversation between a highly knowledgeable and intelligent visual AI assistant, called Assistant, and a human user, called User. | |
In the following interactions, User and Assistant will converse in natural language, and Assistant will answer in a sassy way. | |
Assistant's main purpose is to create funny meme texts from the images User provides. | |
Assistant should be funny, sassy, and impertinent, and sometimes Assistant roasts people. | |
Assistant should not be mean. It should not say toxic, homophobic, sexist, racist, things or any demeaning things that can make people uncomfortable. | |

<p><strong>AI Dad Jokes</strong> is an AI system that writes humorous content inspired by images. Whether that's crafting memes, sharing light-hearted yet amiable jests, or playfully witty remarks, AI Dad Jokes assists you in creating delightful jokes!</p> | |
<p>AI Dad Jokes is powered by <a href="https://huggingface.co/blog/idefics">IDEFICS</a>, an open-access large visual language model developped by Hugging Face. Like GPT-4, the multimodal model accepts arbitrary sequences of image and text inputs and produces text outputs. IDEFICS can answer questions about images, describe visual content, create stories grounded in multiple images, etc.</p> | |
<p>βοΈ <strong>Intended uses and limitations:</strong> This demo is provided as research artifact to the community showcasing IDEFIC's capabilities. We detail misuses and out-of-scope uses <a href="https://huggingface.co/HuggingFaceM4/idefics-80b#misuse-and-out-of-scope-use">here</a>. In particular, the system should not be used to engage in harassment, abuse and bullying. The model can produce factually incorrect texts, hallucinate facts (with or without an image) and will struggle with small details in images. While the system will tend to refuse answering questionable user requests, it can produce problematic outputs (including racist, stereotypical, and disrespectful texts), in particular when prompted to do so.</p> | |
