Meta's Llama 4 Scout 17B struggles to deliver on 10M context promise

By PulseAugur Editorial · [1 sources] ·

Meta's Llama 4 Scout 17B model, announced in April 2025 with a claimed 10 million token context window, faces practical limitations a year later. While the model's configuration technically supports this length, its training data was limited to 256,000 tokens, and most layers operate with an 8,192 token window. Real-world performance, influenced by hardware and task-specific quality, yields context windows closer to 1-2 million tokens, with significant costs associated with achieving even that. AI

IMPACT Highlights the gap between marketing claims and practical performance for large context window models.

    "llama 4 scout 17b": 10 million context on paper, 1-2 million in practice - where does the length break?

    <p>Десять миллионов токенов контекста - такой цифрой Meta открыла анонс Llama 4 Scout 5 апреля 2025 года. Это тысячи страниц текста в одном промпте: целая кодовая база, архив документов, часы транскриптов, и всё без RAG. Год спустя картина трезвая: обучена модель на контексте 256…
