Meta Launches Llama 4: A Native Multimodal MoE Model with 10M Context Window Official Docs

Meta's newly released Llama 4 series introduces a natively trained multimodal foundation model with MoE architecture, currently available in three variants:

Llama 4 Scout
Llama 4 Maverick
Llama 4 Behemoth

Core Technical Innovations

MoE Architecture Breaks Computing Limitations

First implementation of Mixture of Experts (MoE) architecture in Llama series, achieving superior quality under equivalent computational budgets compared to dense models. This aligns with Chinese model DeepSeek V3's approach, signaling MoE's emergence as mainstream architecture for next-gen LLMs.

Native Multimodal Paradigm

Pre-trained with text+image+video joint training from the outset. Features improved MetaCLIP-based visual encoder through independent training strategy for better LLM integration. Note: Currently supports visual understanding (GPT-4 level image analysis) but lacks image generation capabilities.

iRoPE Revolutionizes Positional Encoding

Innovative interleaved attention layers eliminate traditional positional embeddings, enabling:

10M token context window for Scout (equivalent to 15k pages)

1M context for Maverick: Redefining long-context processing standards.

Multilingual & Data Ecosystem

200+ language support: Includes 100+ high-resource languages (>1B tokens each)

10x multilingual data compared to Llama 3

Data sources: Meta ecosystem data (Instagram/Facebook public content), Chinese support remains questionable

Training Breakthroughs:

MetaP auto hyperparameter optimization
FP8 mixed-precision training
Dynamic gradient clipping strategy

Commercialization & Open Source Considerations

New license terms: Enterprises with >700M MAU require special Meta approval

Strategic positioning: Focuses on general-purpose models, trailing in:

Inference optimization (vs DeepSeek R1)

Image generation (vs GPT-4o)

Deployment challenges: Behemoth currently cloud-only, SMEs await distillation breakthroughs

While the native multimodal design may become standard for next-gen models, Llama 4 shows no distinct advantages over specialized inference models like OpenAI's o1/o3 or DeepSeek R1. The release meets expectations but delivers no major surprises, maintaining rather than redefining the state of the art.
