The artificial intelligence landscape has been fundamentally transformed with Meta's release of Llama 4—not merely through incremental improvements, but via architectural breakthroughs that redefine performance-to-cost ratios across the industry. These new models represent the convergence of three critical innovations: native multimodality through early fusion techniques, sparse mixture-of-experts (MoE) architectures that radically improve parameter efficiency, and context window expansions that extend to an unprecedented 10 million tokens.

Llama 4 Scout and Maverick don't just compete with current industry leaders—they systematically outperform them across standard benchmarks while dramatically reducing computational requirements. With Maverick achieving better results than GPT-4o at approximately one-ninth the cost per token, and Scout fitting on a single H100 GPU while maintaining superior performance to models requiring multiple GPUs, Meta has fundamentally altered the economics of advanced AI deployment.

This technical analysis dissects the architectural innovations powering these models, presents comprehensive benchmark data across reasoning, coding, multilingual, and multimodal tasks, and examines the API pricing structures across major providers. For technical decision-makers evaluating AI infrastructure options, we provide detailed performance/cost comparisons and deployment strategies to maximize the efficiency of these groundbreaking models in production environments.

How Llama 4 Archived 10M Context Window?
Mixture-of-Experts (MoE) Implementation
All Llama 4 models employ a sophisticated MoE architecture that fundamentally changes the efficiency equation:
Model | Active Parameters | Expert Count | Total Parameters | Parameter Activation Method |
---|---|---|---|---|
Llama 4 Scout | 17B | 16 | 109B | Token-specific routing |
Llama 4 Maverick | 17B | 128 | 400B | Shared + single routed expert per token |
Llama 4 Behemoth | 288B | 16 | ~2T | Token-specific routing |
The MoE design in Llama 4 Maverick is particularly sophisticated, using alternating dense and MoE layers. Each token activates the shared expert plus one of 128 routed experts, meaning only approximately 17B out of 400B total parameters are active for processing any given token.
Multimodal Architecture
Llama 4 Multimodal Architecture:
├── Text Tokens
│ └── Native text processing pathway
├── Vision Encoder (Enhanced MetaCLIP)
│ ├── Image processing
│ └── Converts images to token sequences
└── Early Fusion Layer
└── Unifies text and vision tokens in model backbone
This early fusion approach allows pre-training on 30+ trillion tokens of mixed text, image, and video data, resulting in significantly more coherent multimodal capabilities than retrofit approaches.
iRoPE Architecture for Extended Context Windows
Llama 4 Scout's 10M token context window leverages the innovative iRoPE architecture:
# Pseudocode for iRoPE architecture
def iRoPE_layer(tokens, layer_index):
if layer_index % 2 == 0:
# Even layers: Interleaved attention without positional embeddings
return attention_no_positional(tokens)
else:
# Odd layers: RoPE (Rotary Position Embeddings)
return attention_with_rope(tokens)
def inference_scaling(tokens, temperature_factor):
# Temperature scaling during inference improves length generalization
return scale_attention_scores(tokens, temperature_factor)
This architecture enables Scout to process documents of unprecedented length while maintaining coherence throughout, with a scaling factor approximately 80x greater than previous Llama models' context windows.
