Llama 4 Model Card

This model card governs the release and use of Meta's Llama 4 collection, comprising Llama 4 Scout (17Bx16E) and Llama 4 Maverick (17Bx128E), multimodal large language models released under the Llama 4 Community License Agreement. The card states that training data includes 'publicly available, licensed data and information from Meta's products and services,' explicitly including 'publicly shared posts from Instagram and Facebook and people's interactions with Meta AI,' and establishes that developers bear responsibility for safety testing, acceptable use compliance, and ensuring deployments in unsupported languages or extended image inputs are 'mitigated for risks.' The document asserts that use in languages or capabilities beyond the 12 explicitly supported is out-of-scope unless developers independently ensure safe and responsible use, and that all reported evaluations were conducted on bf16 models while quantized checkpoints are provided for deployment, creating a potential gap between evaluated and deployed model performance. The card engages AI governance frameworks including the EU AI Act, and its disclosure of training data sourced from Meta platform user interactions may require evaluation under GDPR and CCPA in the context of downstream commercial deployments; the card's open-source release structure means training compute and emissions costs are borne by Meta and not replicated by deployers. The model card's safety obligations are structured as developer responsibilities rather than platform-enforced constraints, meaning compliance with the Acceptable Use Policy and safe deployment practices depends on downstream implementers rather than technical enforcement at the model level.
