+# Megatron Core Export
+
+This module is used to export megatron core models to different inference frameworks. 
+Currently we support TRTLLM export . In the future we will be adding support for VLLM etc. 
+
+## PTQ AND EXPORT
+Follow the instructions in [ptq_and_trtllm_export](./ptq_and_trtllm_export) to do post training quantization, followed by an export to TRTLLM format. 
+
+# TRTLLM EXPORT
+Follow the instructions in [trtllm_export](./trtllm_export/) to do export to TRTLLM checkpoint format alone.

+# Megatron Model Optimization and Deployment
+
+## Installation
+We recommend that users follow TensorRT-LLM's official installation guide to build it from source
+and proceed with a containerized environment (`docker.io/tensorrt_llm/release:latest`):
+
+```sh
+git clone https://github.com/NVIDIA/TensorRT-LLM.git
+cd TensorRT-LLM
+git checkout v0.10.0
+make -C docker release_build
+```
+
+> **TROUBLE SHOOTING:** rather than copying each folder separately in `docker/Dockerfile.multi`,
+> you may need to copy the entire dir as `COPY ./ /src/tensorrt_llm` since a `git submodule` is
+> called later which requires `.git` to continue.
+
+Once the container is built, install `nvidia-modelopt` and additional dependencies for sharded checkpoint support:
+```sh
+pip install "nvidia-modelopt[all]~=0.13.0" --extra-index-url https://pypi.nvidia.com
+pip install zarr tensorstore==0.1.45
+```
+TensorRT-LLM quantization functionalities are currently packaged in `nvidia-modelopt`.
+You can find more documentation about `nvidia-modelopt` [here](https://nvidia.github.io/TensorRT-Model-Optimizer/).
+
+## Support Matrix
+
+The following matrix shows the current support for the PTQ + TensorRT-LLM export flow.
+
+| model                       | fp16 | int8_sq | fp8 | int4_awq |
+|-----------------------------|------|---------| ----| -------- |
+| nextllm-2b                  | x    | x       |   x |          |
+| nemotron3-8b                | x    |         |   x |          |
+| nemotron3-15b               | x    |         |   x |          |
+| llama2-text-7b              | x    | x       |   x |      TP2 |
+| llama2-chat-70b             | x    | x       |   x |      TP4 |
+
+Our PTQ + TensorRT-LLM flow has native support on MCore `GPTModel` with a mixed layer spec (native ParallelLinear
+and Transformer-Engine Norm (`TENorm`). Note that this is not the default mcore gpt spec. You can still load the
+following checkpoint formats with some remedy:
+
+| GPTModel                          | sharded |                        remedy arguments     |
+|-----------------------------------|---------|---------------------------------------------|
+| megatron.legacy.model             |         | `--export-legacy-megatron` |
+| TE-Fused (default mcore gpt spec) |         | `--export-te-mcore-model`       |
+| TE-Fused (default mcore gpt spec) |       x |                                             |
+
+> **TROUBLE SHOOTING:** If you are trying to load an unpacked `.nemo` sharded checkpoint, then typically you will
+> need to adding `additional_sharded_prefix="model."` to `modelopt_load_checkpoint()` since NeMo has an additional
+> `model.` wrapper on top of the `GPTModel`.
+
+> **NOTE:** flag `--export-legacy-megatron` may not work on all legacy checkpoint versions.
+
+## Examples
+
+> **NOTE:** we only provide a simple text generation script to test the generated TensorRT-LLM engines. For
+> a production-level API server or enterprise support, see [NeMo](https://github.com/NVIDIA/NeMo) and TensorRT-LLM's
+> backend for [NVIDIA Triton Inference Server](https://developer.nvidia.com/nvidia-triton-inference-server).
+
+### Minitron-8B FP8 Quantization and TensorRT-LLM Deployment
+First download the nemotron checkpoint from https://huggingface.co/nvidia/Minitron-8B-Base, extract the
+sharded checkpoint from the `.nemo` tarbal and fix the tokenizer file name.
+
+> **NOTE:** The following cloning method uses `ssh`, and assume you have registered the `ssh-key` in Hugging Face.
+> If you are want to clone with `https`, then `git clone https://huggingface.co/nvidia/Minitron-8B-Base` with an access token.
+
+```sh
+git lfs install
+git clone git@hf.co:nvidia/Minitron-8B-Base
+cd Minitron-8B-Base/nemo
+tar -xvf minitron-8b-base.nemo
+cd ../..
+```
+
+Now launch the PTQ + TensorRT-LLM export script,
+```sh
+bash examples/export/ptq_and_trtllm_export/ptq_trtllm_minitron_8b ./Minitron-8B-Base None
+```
+By default, `cnn_dailymail` is used for calibration. The `GPTModel` will have quantizers for simulating the
+quantization effect. The checkpoint will be saved optionally (with quantizers as additional states) and can
+be restored for further evaluation or quantization-aware training. TensorRT-LLM checkpoint and engine are exported to `/tmp/trtllm_ckpt` and
+built in `/tmp/trtllm_engine` by default.
+
+The script expects `${CHECKPOINT_DIR}` (`./Minitron-8B-Base/nemo`) to have the following structure:
+
+> **NOTE:** The .nemo checkpoint after extraction (including examples below) should all have the following strucure.
+
+```
+├── model_weights
+│   ├── common.pt
+│   ...
+│
+├── model_config.yaml
+│...
+```
+
+> **NOTE:** The script is using `TP=8`. Change `$TP` in the script if your checkpoint has a different tensor
+> model parallelism.
+
+Then build TensorRT engine and run text generation example using the newly built TensorRT engine
+
+```sh
+export trtllm_options=" \
+    --checkpoint_dir /tmp/trtllm_ckpt \
+    --output_dir /tmp/trtllm_engine \
+    --max_input_len 2048 \
+    --max_seq_len 512 \
+    --max_batch_size 8 "
+
+trtllm-build ${trtllm_options}
+
+python examples/export/ptq_and_trtllm_export/trtllm_text_generation.py --tokenizer nvidia/Minitron-8B-Base
+```
+
+### mistral-12B FP8 Quantization and TensorRT-LLM Deployment
+First download the nemotron checkpoint from https://huggingface.co/nvidia/Mistral-NeMo-12B-Base, extract the
+sharded checkpoint from the `.nemo` tarbal.
+
+> **NOTE:** The following cloning method uses `ssh`, and assume you have registered the `ssh-key` in Hugging Face.
+> If you are want to clone with `https`, then `git clone https://huggingface.co/nvidia/Mistral-NeMo-12B-Base` with an access token.
+
+```sh
+git lfs install
+git clone git@hf.co:nvidia/Mistral-NeMo-12B-Base
+cd Mistral-NeMo-12B-Base
+tar -xvf Mistral-NeMo-12B-Base.nemo
+cd ..
+```
+
+Then log in to huggingface so that you can access to model
+
+> **NOTE:** You need a token generated from huggingface.co/settings/tokens and access to mistralai/Mistral-Nemo-Base-2407 on huggingface
+
+```sh
+pip install -U "huggingface_hub[cli]"
+huggingface-cli login
+```
+
+Now launch the PTQ + TensorRT-LLM checkpoint export script,
+
+```sh
+bash examples/export/ptq_and_trtllm_export/ptq_trtllm_mistral_12b.sh ./Mistral-NeMo-12B-Base None
+```
+
+Then build TensorRT engine and run text generation example using the newly built TensorRT engine
+
+```sh
+export trtllm_options=" \
+    --checkpoint_dir /tmp/trtllm_ckpt \
+    --output_dir /tmp/trtllm_engine \
+    --max_input_len 2048 \
+    --max_seq_len 512 \
+    --max_batch_size 8 "
+
+trtllm-build ${trtllm_options}
+
+python examples/export/ptq_and_trtllm_export/trtllm_text_generation.py --tokenizer mistralai/Mistral-Nemo-Base-2407
+```
+
+
+### llama2-text-7b INT8 SmoothQuant and TensorRT-LLM Deployment
+> **NOTE:** Due to the LICENSE issue, we do not provide a MCore checkpoint to download. Users can follow
+> the instruction in `docs/llama2.md` to convert the checkpoint to megatron legacy `GPTModel` format and
+> use `--export-legacy-megatron` flag which will remap the checkpoint to the MCore `GPTModel` spec
+> that we support.
+
+```sh
+bash examples/export/ptq_and_trtllm_export/ptq_trtllm_llama_7b.sh ${CHECKPOINT_DIR}
+```
+
+The script expect `${CHECKPOINT_DIR}` to have the following structure:
+```
+├── hf
+│   ├── tokenizer.config
+│   ├── tokenizer.model
+│   ...
+│
+├── iter_0000001
+│   ├── mp_rank_00
+│   ...
+│
+├── latest_checkpointed_iteration.txt
+```
+In short, other than the converted llama megatron checkpoint, also put the Hugging Face checkpoint inside as
+the source of the tokenizer.
+
+Then build TensorRT engine and run text generation example using the newly built TensorRT engine
+
+```sh
+export trtllm_options=" \
+    --checkpoint_dir /tmp/trtllm_ckpt \
+    --output_dir /tmp/trtllm_engine \
+    --max_input_len 2048 \
+    --max_seq_len 512 \
+    --max_batch_size 8 "
+

+> **NOTE:** For llama3.1, the missing rope_scaling parameter will be fixed in modelopt-0.19 and trtllm-0.13.
+
+> **NOTE:** There are two ways to acquire the checkpoint. Users can follow
+> the instruction in `docs/llama2.md` to convert the checkpoint to megatron legacy `GPTModel` format and
+> use `--export-legacy-megatron` flag which will remap the checkpoint to the MCore `GPTModel` spec
+> that we support.
+> Or Users can download [nemo model](https://catalog.ngc.nvidia.com/orgs/nvidia/teams/nemo/models/llama38bnemo) from NGC and extract the sharded checkpoint from the .nemo tarbal.
+
+If users choose to download the model from NGC, first extract the sharded checkpoint from the .nemo tarbal.
+
+```sh
+tar -xvf 8b_pre_trained_bf16.nemo
+```
+
+> **NOTE:** You need a token generated from huggingface.co/settings/tokens and access to meta-llama/Llama-3.1-8B or meta-llama/Llama-3-8B on huggingface
+
+```sh
+pip install -U "huggingface_hub[cli]"
