Meta Releases Llama 4 Scout and Maverick with 10M Context
Meta has released Llama 4 Scout and Maverick. These open models feature a 10-million-token context window and are built on a Mixture-of-Experts (MoE) architecture with 17 billion active parameters.

What happened?
Meta has launched the AI models Llama 4 Scout and Llama 4 Maverick, which are based on a Mixture of Experts architecture with open model weights. Both models are multimodal from the ground up and feature a context window of up to 10 million tokens. Scout and Maverick each have 17 billion active parameters, distributed across 16 and 128 experts, respectively.
Key facts
Why it matters
By offering open models with MoE architecture, computational costs during inference are reduced, as only a portion of the parameters are activated per token. This provides organisations with greater control over their data and lowers costs for tasks that require the handling of extensive context.
Who is affected?
The launch is aimed at AI developers, researchers, and companies looking to build multimodal applications with large amounts of data without relying on proprietary cloud services.
Impact on the EU
The models with open weights can be downloaded and run locally within the EU, enabling European organisations to manage data in compliance with local data protection requirements.
What else you should know
Scout is specifically optimised to fit onto a single Nvidia H100 graphics processor, which lowers the barrier for local deployment of models with extremely long context windows.
