Meta AI 的技术特点

Understanding the underlying technology helps you appreciate why Meta AI delivers such strong performance. The technical foundation combines innovative architecture with proven methodologies to create models that excel in both capability and efficiency.

Mixture-of-Experts Architecture

Llama 4 introduces Meta's implementation of the Mixture-of-Experts (MoE) architecture, a revolutionary approach that activates only relevant model components for each task. Think of it like having a team of specialists where only the right expert handles each question—this dramatically improves efficiency without sacrificing quality. The result is a model that delivers 405B-level performance while operating at a fraction of the computational cost.

Native Multimodality with Early Fusion

Unlike models that bolt on image capabilities after training on text alone, Llama 4 uses Early Fusion technology—pre-training on text and visual data together from the ground up. This integrated approach enables true native multimodality, where the model understands and generates content across modalities seamlessly. The proof is in the benchmark numbers: Llama 4 Maverick achieves 73.4% on MMMU (multimodal understanding) and 94.4% on DocVQA (document visual question answering).

Revolutionary Context Window

Perhaps the most striking technical achievement is support for up to 10 million token context windows—a capability that opens entirely new use cases. Imagine analyzing entire codebases, processing hundreds of legal documents, or running complex analyses across massive datasets in a single conversation. Llama 4 Scout achieves this efficiency on a single H100 GPU, making long-context AI accessible without requiring massive infrastructure.

Self-Supervised Learning at Scale

Meta's research leadership shines through in models like DINOv3, which pioneered large-scale visual self-supervised learning, and V-JEPA 2, the first world model trained on video. These approaches eliminate the need for massive labeled datasets—a traditional bottleneck in AI development—while achieving state-of-the-art results across vision and video understanding tasks.

Performance That Speaks for Itself

The benchmarks tell a compelling story. Llama 4 Maverick delivers:

• 80.5% MMLU Pro (reasoning)
• 69.8% GPQA Diamond (graduate-level reasoning)
• 73.4% MMMU (multimodal)
• 73.7% MathVista (mathematical reasoning)

And with inference costs at just $0.19-$0.49 per million tokens, you're getting cutting-edge performance at accessible price points.
