It analyzes text with one or more images and returns a safe/unsafe label plus applicable hazard categories, using a dense architecture pruned from Llama 4 Scout. - [**Ailoot Ultra · OpenAI Chat** `POST /v1/chat/completions` `meta-llama/llama-guard-4-12b`](https://ailoot.ai/models/en/meta-llama-llama-guard-4-12b/#method-0) - [**Ailoot Ultra · Anthropic Messages** `POST /v1/messages` `meta-llama/llama-guard-4-12b`](https://ailoot.ai/models/en/meta-llama-llama-guard-4-12b/#method-1) About the model This description covers the model’s capabilities. Available in Ailoot inputs, outputs and options are listed for the selected method below. Llama Guard 4 12B is Meta's natively multimodal safety classifier with 12 billion parameters. It is trained jointly on text and multiple images and generates a textual classification: safe or unsafe, with violated hazard categories when the result is unsafe. Its purpose is evaluating content in a prompt or generated response rather than acting as a general chat assistant. Prompt and response classification The model can classify material before it is sent to a generative model, after that model produces an answer, or at both points. These are different questions. Prompt classification evaluates the user's input, while response classification evaluates what an assistant actually wrote. A system can therefore distinguish a risky request from a response that handles the request in an acceptable way under the classifier's taxonomy. Supply the exact content to classify with the conversation roles and relevant context. If the target is a response, retain the question that gives the response its meaning. For a mixed text-and-image input, include the images associated with that prompt rather than classifying unrelated text or one arbitrarily selected image. The classifier result is information for the application's rule or review step; it does not itself block a request or change a file. Fourteen hazard categories The maker aligns the classifier with the MLCommons hazard taxonomy and adds a text-only code-interpreter category. The fourteen labels cover violent crimes, non-violent crimes, sex-related crimes, child sexual exploitation, defamation, specialized advice, privacy, intellectual property, indiscriminate weapons, hate, suicide and self-harm, sexual content, elections and code interpreter abuse. The categories use identifiers S1 through S14. S14, Code Interpreter Abuse, is specifically for text-only tool-call use cases. Keep the taxonomy identifier with the safe/unsafe result so a later application step can interpret the classification under the same category definitions. A short result is a category judgment, not a full explanation, legal determination or guarantee that every possible harm has been detected. For an illustrative format, an unsafe classification can be followed by the applicable category identifier. Retain the original evaluated text, its source or conversation position and the returned labels together. That association lets an application distinguish the content examined from a subsequent rewritten response or a separate prompt. Architecture and training Llama Guard 4 has a dense early-fusion Transformer architecture, pruned from a pretrained Llama 4 Scout checkpoint. The maker removes routed experts and router layers and retains the shared dense expert, then post-trains the resulting model for content classification. It performs no additional pretraining after that pruning step. This creates a different model from Scout's mixture-of-experts chat edition. The model shares the Llama 4 tokenizer and vision encoder and combines text-only and multimodal classification training. The maker describes multilingual data and multi-image training, with most such samples containing two to five images and an approximate three-to-one blend of text-only to multimodal data. Those are training characteristics, not hard input-count limits. The documented multilingual scope follows the languages supported by Llama Guard 3, and the card discusses English together with French, German, Hindi, Italian, Portuguese, Spanish and Thai. A classification request should preserve the actual wording and visual context in the language being evaluated rather than replacing the content with an unrelated summary. Preparing a useful classification result For an input check, provide the user's message and its associated images and ask for the prompt classification in the maker's format. For an output check, provide the assistant's actual response together with the relevant prior message. A multi-image example can retain the text linking the images so the model evaluates the combined request rather than independent fragments without context. The model card demonstrates applying the matching conversation template and decoding only the generated classification. Its ten-token generation example illustrates a short label result; that number is not a separate maximum answer capacity. Keep the requested output aligned with the classifier's purpose instead of asking it to write an ordinary conversational answer. Specific limitations The maker states that judgments may be limited by the model's training data, common-sense knowledge, language coverage and policy coverage. Defamation, intellectual property and election-related categories can require factual, current knowledge that the classifier may not possess. The category label should therefore retain its relationship to the content and the information available for that evaluation. The card reports testing mostly on prompts with a few images, most often three, and notes that behavior may vary with a much larger image collection. This describes the tested scope rather than a universal three-image maximum. The model can also be susceptible to adversarial or prompt-injection content that changes its intended behavior. Llama Guard 4's classifier role should not inherit Scout's context specification or general assistant capabilities merely because it was pruned from Scout. The card read does not give a separate hard context or output-token capacity for this classifier. Preserve the evaluated material and taxonomy labels as the practical artifact, and let the application decide the action associated with that result. Practical task ### Classify a benign library prompt Technical example in English ``` Classify a benign library prompt Classify this user prompt using Llama Guard 4's prompt-safety taxonomy: 'Summarize the public library opening hours from the notice I pasted, and list any days when it is closed.' Evaluate the quoted prompt itself, not an imagined answer. Return the documented safe or unsafe classification; include S1-S14 hazard identifiers only if applicable. ``` #### Expected result ``` The documented safe/unsafe label, with applicable S1-S14 identifiers only for an unsafe result. ``` #### Check the result ``` Check the output uses only the documented classifier labels and does not answer the library-hours question. ``` **Ailoot Ultra · OpenAI Chat** `POST /v1/chat/completions` `meta-llama/llama-guard-4-12b` [`meta-llama/llama-guard-4-12b`](https://ailoot.ai/models/en/#m=meta-llama%2Fllama-guard-4-12b&route=Ultra&caller=meta-llama%2Fllama-guard-4-12b&fmt=chat) Meta /`meta-llama/llama-guard-4-12b` ### Overview Llama Guard 4 12B is Meta's multimodal content classifier for prompts and generated responses.
