Meta: Llama 3.2 11B Vision Instruct

Processes images and natural language instructions simultaneously using a vision encoder that extracts spatial-semantic features from images, then fuses them with text embeddings in a unified transformer backbone. The model uses instruction-tuning to follow complex directives about image analysis, enabling it to answer questions, describe content, and reason about visual relationships based on user prompts. Architecture combines a vision transformer (ViT) for image tokenization with a language model decoder for grounded text generation.

Answers natural language questions about image content by grounding language tokens to image regions through cross-attention mechanisms between vision and language embeddings. The model learns to identify relevant visual features corresponding to question terms, then generates answers that reference spatial relationships, object properties, and scene context. Instruction-tuning enables the model to handle diverse question types (what, where, why, how many) without explicit task-specific training.

Generates natural language captions and detailed descriptions of image content by encoding visual features through a vision transformer, then decoding them into coherent text sequences using an instruction-tuned language model. The model learns to identify salient objects, actions, and relationships, then articulate them in grammatically correct, contextually appropriate descriptions. Supports variable-length outputs from short captions to paragraph-length descriptions based on prompt guidance.

Extracts and recognizes text content from images containing documents, signs, screenshots, or printed material by processing visual features through the vision encoder and generating structured text output. The model learns to identify text regions, recognize characters, and preserve layout information (to a limited degree) through instruction-tuning on OCR-like tasks. Handles various document types including forms, tables, receipts, and handwritten text with varying success depending on image quality and text clarity.

Analyzes images to identify potentially harmful, inappropriate, or policy-violating content by processing visual features and generating natural language assessments of image safety. The model can be prompted to classify content across multiple safety dimensions (violence, adult content, hate symbols, etc.) and provide reasoning for classifications. Leverages instruction-tuning to follow detailed safety assessment prompts without requiring fine-tuning on proprietary safety datasets.

Performs multi-step reasoning about image content by analyzing spatial relationships, object interactions, and scene context to answer complex questions or make inferences. The model processes visual features through cross-attention mechanisms that link objects and relationships, then generates reasoning chains that explain how visual elements relate to answer questions. Instruction-tuning enables the model to follow explicit reasoning prompts (e.g., 'explain step-by-step') without task-specific training.

Processes multiple images sequentially through OpenRouter API with support for streaming text responses, enabling efficient batch workflows for image analysis at scale. The API integration handles image encoding, request batching, and response streaming, allowing developers to process image collections without managing model inference directly. Supports concurrent requests within API rate limits, with streaming responses reducing perceived latency for long-form outputs.
