About Llama 4 Scout

Llama 4 Scout is a 109 billion parameter Mixture-of-Experts (MoE) multimodal LLM with 17 billion active parameters and 16 experts, designed for efficient, large-scale reasoning over both text and images. It excels in tasks requiring extremely long context—supporting up to a 10 million token window—making it particularly strong for multi-document summarization, codebase analysis, and personalized automation based on extensive user data[1][2][4][6].

Some other noteworthy features of Llama 4 Scout include native support for both text and image inputs (multimodality), multilingual capabilities across twelve major languages, and compute efficiency that allows it to run on a single H100 GPU with quantization. Its architecture enables high performance in image understanding (e.g., visual question answering), long-context retrieval tasks (“needle-in-a-haystack”), coding benchmarks, and advanced reasoning—all while maintaining lower inference costs compared to similarly sized dense models.
