Llama 4 Scout: features, use cases and important details

Llama 4 Scout is Meta’s long-context multimodal model from the Llama 4 family.

Llama 4 Scout verified specifications

Meta’s official model card lists 17B active parameters, 109B total parameters and a 10-million-token context window. Scout accepts multilingual text and images and generates multilingual text and code.

License and deployment

The weights are distributed under the Llama 4 Community License and can be deployed on private infrastructure or through cloud providers. There is no single Meta token price for the downloadable weights.

Best uses

Scout is particularly attractive for massive document collections, multimodal research, private assistants and custom deployments that benefit from very long context.

Limitations

It has an August 2024 knowledge cutoff, substantial hardware requirements and a custom community license rather than a standard open-source license.

Practical use cases

  • Massive-context analysis
  • Private assistants
  • Research
  • Multimodal Q&A
  • Custom fine-tuning
Pricing

What does it cost?

Meta distributes Llama 4 Scout as downloadable weights under the Llama 4 Community License. There is no single Meta token price; hosting cost depends on the infrastructure or cloud provider.

Simple summaryThe weights do not have a Meta per-token charge, but a 109B-total MoE still requires substantial GPU memory and serving infrastructure.

What stands out

  • 10M context
  • Downloadable weights
  • Multimodal input
  • Broad language support
  • Lower active parameters than total size

Things to consider

  • Large deployment footprint
  • Custom community license
  • Static August 2024 knowledge cutoff
Limitations

Important restrictions and trade-offs

  • Self-hosting is hardware intensive
  • The license is not a standard OSI open-source license
  • Long context does not guarantee perfect recall
SimplifyAITools verdict

Our editorial take

One of the most searched open-weight Llama variants because its 10M-token context makes it unusually suited to massive document and multimodal workloads.
