Llama 4 Scout and Maverick

Llama 4 Scout and Llama 4 Maverick are Meta models released in April 2025. Meta describes both as natively multimodal mixture-of-experts models. Research and community discussion continue to refine understanding of Llama 4 Scout and Maverick. Academic work on Llama 4 Scout and Maverick appears in conferences such as NeurIPS, ICML, ICLR, and journals including Journal of Machine Learning Research. Preprints on arXiv provide early results on architectures, training methods, and evaluation. Practitioners discuss implementation details on forums like Reddit r/MachineLearning, Hacker News, and professional Slack communities. Key themes include reproducibility, benchmark validity, safety, and cost. When assessing Llama 4 Scout and Maverick, readers should check dated primary sources, system cards, and independent audits rather than marketing claims.

Meta described Scout as a model with 17 billion active parameters and 16 experts. Maverick also uses 17 billion active parameters but 128 experts, giving it much larger total capacity while keeping per-token activation relatively sparse.

In an MoE model, the total number of stored parameters is not the same as the number used for each token. Routing activates only selected experts. That distinction is essential when comparing MoE models with dense models where nearly all parameters participate in each forward pass.

Meta introduced Llama 4 Scout and Llama 4 Maverick as natively multimodal members of the Llama 4 family. Scout was positioned for efficiency and very long context, while Maverick targeted stronger general multimodal performance. Both use mixture-of-experts techniques, meaning only part of the total parameter set is active for a given token. That makes total parameter count an incomplete proxy for serving cost. Meta's own documentation should be the reference for context limits and hardware claims, because community quantizations and third-party deployments can use different settings. The models are available as weights, which enables local or private deployment but also means the operator must handle inference software, access control, updates and safety configuration. Llama 4 should not be described as simply 'an open-source GPT replacement'; the licensing model, architecture and deployment ecosystem are different. Scout and Maverick are also distinct products with different trade-offs, so benchmark results or context claims from one should not be transferred casually to the other.

The evidence for Llama 4 Scout and Maverick is strongest when the subject is kept specific. The sections on What are Scout and Maverick?, How the two models differ, and Why active parameters matter describe different pieces of the story rather than interchangeable labels. Model status changes quickly; exact version identifiers and dated first-party release notes are more reliable than an undated claim that a model is “latest.” For verification, the reference set includes Wikipedia reference guide, Meta — Llama 4, Meta — Llama developer resources. Those materials provide a way to distinguish a documented mechanism or release fact from commentary that accumulated later. Current specifications should always be read with a date, and historical achievements should be described in the terms of what the original system actually accomplished. That discipline is especially important in AI, where marketing language and retrospect can make distinct technologies sound more similar than the record supports.
