Usage and Limitations These models have certain limitations that users should be aware of.
Intended Usage Open vision-language models (VLMs) models have a wide range of applications across various industries and domains. The following list of potential uses is not comprehensive. The purpose of this list is to provide contextual information about the possible use-cases that the model creators considered as part of model training and development.
Content Creation and Communication Text Generation: These models can be used to generate creative text formats such as poems, scripts, code, marketing copy, and email drafts. Chatbots and Conversational AI: Power conversational interfaces for customer service, virtual assistants, or interactive applications. Text Summarization: Generate concise summaries of a text corpus, research papers, or reports. Image Data Extraction: These models can be used to extract, interpret, and summarize visual data for text communications. Research and Education Natural Language Processing (NLP) and VLM Research: These models can serve as a foundation for researchers to experiment with VLM and NLP techniques, develop algorithms, and contribute to the advancement of the field. Language Learning Tools: Support interactive language learning experiences, aiding in grammar correction or providing writing practice. Knowledge Exploration: Assist researchers in exploring large bodies of text by generating summaries or answering questions about specific topics. Limitations Training Data The quality and diversity of the training data significantly influence the model's capabilities. Biases or gaps in the training data can lead to limitations in the model's responses. The scope of the training dataset determines the subject areas the model can handle effectively. Context and Task Complexity Models are better at tasks that can be framed with clear prompts and instructions. Open-ended or highly complex tasks might be challenging. A model's performance can be influenced by the amount of context provided (longer context generally leads to better outputs, up to a certain point). Language Ambiguity and Nuance Natural language is inherently complex. Models might struggle to grasp subtle nuances, sarcasm, or figurative language. Factual Accuracy Models generate responses based on information they learned from their training datasets, but they are not knowledge bases. They may generate incorrect or outdated factual statements. Common Sense Models rely on statistical patterns in language. They might lack the ability to apply common sense reasoning in certain situations. Ethical Considerations and Risks The development of vision-language models (VLMs) raises several ethical concerns. In creating an open model, we have carefully considered the following:
Bias and Fairness VLMs trained on large-scale, real-world text and image data can reflect socio-cultural biases embedded in the training material. These models underwent careful scrutiny, input data pre-processing described and posterior evaluations reported in this card. Misinformation and Misuse VLMs can be misused to generate text that is false, misleading, or harmful. Guidelines are provided for responsible use with the model, see the Responsible Generative AI Toolkit. Transparency and Accountability: This model card summarizes details on the models' architecture, capabilities, limitations, and evaluation processes. A responsibly developed open model offers the opportunity to share innovation by making VLM technology accessible to developers and researchers across the AI ecosystem. Risks identified and mitigations:
Perpetuation of biases: It's encouraged to perform continuous monitoring (using evaluation metrics, human review) and the exploration of de-biasing techniques during model training, fine-tuning, and other use cases. Generation of harmful content: Mechanisms and guidelines for content safety are essential. Developers are encouraged to exercise caution and implement appropriate content safety safeguards based on their specific product policies and application use cases. Misuse for malicious purposes: Technical limitations and developer and end-user education can help mitigate against malicious applications of VLMs. Educational resources and reporting mechanisms for users to flag misuse are provided. Prohibited uses of Gemma models are outlined in the Gemma Prohibited Use Policy. Privacy violations: Models were trained on data filtered for removal of certain personal information and other sensitive data. Developers are encouraged to adhere to privacy regulations with privacy-preserving techniques. Benefits At the time of release, this family of models provides high-performance open vision-language model implementations designed from the ground up for responsible AI development compared to similarly sized models.
Using the benchmark evaluation metrics described in this document, these models have shown to provide superior performance to other, comparably-sized open model alternatives.
