# Model Overview
## Description:
The NVIDIA Llama 4 Maverick 17B 128E Eagle3 BF16 model is a natively multimodal model that enables text and multimodal experiences. The model is the Eagle head of Meta's Llama 4 Maverick 17B 128E model, which is an auto-regressive language model that uses a mixture-of-experts (MoE) architecture and incorporates early fusion for native multimodality. For more information, please check [here](https://huggingface.co/meta-llama/Llama-4-Maverick-17B-128E). The NVIDIA Llama 4 Maverick 17B 128E Eagle3 BF16 model incorporates Eagle speculative decoding with [TensorRT Model Optimizer](https://github.com/NVIDIA/TensorRT-Model-Optimizer).
This model is ready for commercial and non-commercial use.

## Eagle Speculative Decoding
Synthesized data was obtained from Meta's Llama 4 Maverick 17B 128E model, which is then used to finetune the Eagle modules. This model is ready for inference with TensorRT-LLM in Eagle speculative decoding mode. Eagle modules are used to predict candidate tokens beyond the next token. In the generation step, each forward Eagle module generates a distribution of tokens beyond the previous. Then, a tree-based attention mechanism samples some candidate sequences for the original model to validate. The longest accepted candidate sequence is selected so that more than 1 token is returned in the generation step. The number of tokens generated in each step is called acceptance rate.
## Usage
To serve the quantized checkpoint with [TensorRT-LLM](https://github.com/NVIDIA/TensorRT-LLM), follow the sample commands below with the TensorRT-LLM GitHub repo:
```sh
trtllm-serve --host 0.0.0.0 --port 8000 --backend pytorch --max_batch_size 32 --max_num_tokens 8192 --max_seq_len 8192 --tp_size 8 --extra_llm_api_options extra-llm-api-config.yml
```
`extra-llm-api-config.yml` is like this
```sh
enable_attention_dp: false
pytorch_backend_config:
enable_overlap_scheduler: false
use_cuda_graph: true
cuda_graph_max_batch_size: 1
autotuner_enabled: false
speculative_config:
decoding_type: Eagle
max_draft_len: 3
