Llama 4 Scout
Llama 4 Scout is an API model from Meta AI. It’s positioned for vision + text tasks—work that benefits from iteration, not just one-shot answers.

How are Intelligence, Speed & Cost bucketed?
Intelligence and Speed buckets are percentile ranks on
Artificial Analysis. Cost buckets are fixed dollar
thresholds keyed off output-token price ($/M out).

Self-host Capability / Performance
Where this model sits relative to the middle 60% of models in the tree. All scores are 0–10 (higher is better).

Percentile boundaries are computed across every model in the tree that reports the underlying benchmark for each capability.
What it feels like
- Scout variant — 17B active / 16 experts; 10M-token context.
- Meta's first MoE-native Llama and first natively multimodal open-weights generation
- Maverick (17B active / 128 experts) beats GPT-4o and Gemini 2.0 Flash on most benchmarks at release
- Scout (17B active / 16 experts) fits in a single H100 with a claimed 10M-token context window
Best use cases
- Self-hosted multimodal applications where API models can't go
- Long-context retrieval and document QA (especially Scout's 10M window)
- Fine-tuning on private data while staying inside Meta's open license
Tools to try
Not ideal for
- Frontier-leaderboard reasoning — Claude 4, GPT-5, DeepSeek R1 score higher
- Edge / single-consumer-GPU deployments (even Scout needs an H100)
