The LLM can also be selected for the AI agent to use when processing documents and images. Multimodal LLMs support image mode by processing multiple types of inputs — such as text, sound, and images — to generate a text response. Processing may take longer for image inputs. **Note:** The Content insights AI agent requires a multimodal LLM. The text-only Now LLM Service is not supported for the AI agent. AI-generated outputs may be inaccurate or incomplete. Review all AI-generated content before use. The following table lists the available LLMs for Content Understanding. |LLM|Highlights| |---|----------| |Now LLM Service - Large|Text-only model that supports natural language understanding, automation, and decision support.| |Now LLM Service - Small|Text-only model that enhances text-based automation and content generation in ServiceNow workflows.| |Google Cloud - Gemini Large|Multimodal model with advanced reasoning and problem-solving capabilities.| |Google Cloud - Gemini Small|Multimodal model with strong performance in summarization, rewriting, and content transformation.| |Azure OpenAI - GPT Large|Multimodal model with strong performance on tasks involving analysis, summarization, and multi-step problem solving.| |Azure OpenAI - GPT Small \(default\)|Multimodal model optimized for routine workflows, including summarization, paraphrasing, and question and answer tasks.| |Amazon Bedrock - Claude Large|Multimodal model with strong context management for long documents and dialogs.| |Amazon Bedrock - Claude Small|Multimodal model with lower latency and higher efficiency for real-time applications.| For more information, see [Large language models on the ServiceNow AI Platform](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/intelligent-experiences/servicenow-large-language-model-now-llm/exploring-large-language-models.md). **Parent Topic:**[Content Understanding Reference](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/intelligent-experiences/content-understanding-reference.md)
