Llama 4 Scout but with topk=6 experts with dynamic expert fusion. Requires healing via SFT/RLHF to restore performance. Achieves 64.28% MMLU score. Barely fits on a RTX 4090 when quantized to 4bit.




## Model Information

The Llama 4 collection of models are natively multimodal AI models that enable text and multimodal experiences. These models leverage a mixture-of-experts architecture to offer industry-leading performance in text and image understanding. 

These Llama 4 models mark the beginning of a new era for the Llama ecosystem. We are launching two efficient models in the Llama 4 series, Llama 4 Scout, a 17 billion parameter model with 16 experts, and Llama 4 Maverick, a 17 billion parameter model with 128 experts.

**Model developer**: Meta

**Model Architecture:**  The Llama 4 models are auto-regressive language models that use a mixture-of-experts (MoE) architecture and incorporate early fusion for native multimodality.
