+"""
+tensorize_vllm_model.py is a script that can be used to serialize and 
+deserialize vLLM models. These models can be loaded using tensorizer 
+to the GPU extremely quickly over an HTTP/HTTPS endpoint, an S3 endpoint,
+or locally. Tensor encryption and decryption is also supported, although 
+libsodium must be installed to use it. Install vllm with tensorizer support 
+using `pip install vllm[tensorizer]`. To learn more about tensorizer, visit
+https://github.com/coreweave/tensorizer
+
+To serialize a model, install vLLM from source, then run something 
+like this from the root level of this repository:
+
+python -m examples.tensorize_vllm_model \
+   --model facebook/opt-125m \
+   serialize \
+   --serialized-directory s3://my-bucket \
+   --suffix v1
+   
+Which downloads the model from HuggingFace, loads it into vLLM, serializes it,
+and saves it to your S3 bucket. A local directory can also be used. This
+assumes your S3 credentials are specified as environment variables
+in the form of `S3_ACCESS_KEY_ID`, `S3_SECRET_ACCESS_KEY`, and 
+`S3_ENDPOINT_URL`. To provide S3 credentials directly, you can provide 
+`--s3-access-key-id` and `--s3-secret-access-key`, as well as `--s3-endpoint` 
+as CLI args to this script.
+
+You can also encrypt the model weights with a randomly-generated key by 
+providing a `--keyfile` argument.
+
+To deserialize a model, you can run something like this from the root 
+level of this repository:
+
+python -m examples.tensorize_vllm_model \
+   --model EleutherAI/gpt-j-6B \
+   --dtype float16 \
+   deserialize \
+   --path-to-tensors s3://my-bucket/vllm/EleutherAI/gpt-j-6B/v1/model.tensors
+
+Which downloads the model tensors from your S3 bucket and deserializes them.
+
+You can also provide a `--keyfile` argument to decrypt the model weights if 
+they were serialized with encryption.
+
+For more information on the available arguments for serializing, run 
+`python -m examples.tensorize_vllm_model serialize --help`.
+
+Or for deserializing:
+
+`python -m examples.tensorize_vllm_model deserialize --help`.
+
+Once a model is serialized, tensorizer can be invoked with the `LLM` class 
+directly to load models:
+
+    llm = LLM(model="facebook/opt-125m",
+              load_format="tensorizer",
+              model_loader_extra_config=TensorizerConfig(
+                    tensorizer_uri = path_to_tensors,
+                    num_readers=3,
+                    )
+              )
+            
+A serialized model can be used during model loading for the vLLM OpenAI
+inference server. `model_loader_extra_config` is exposed as the CLI arg
+`--model-loader-extra-config`, and accepts a JSON string literal of the
+TensorizerConfig arguments desired.
+
+In order to see all of the available arguments usable to configure 
+loading with tensorizer that are given to `TensorizerConfig`, run:
+
+`python -m examples.tensorize_vllm_model deserialize --help`
+
+under the `tensorizer options` section. These can also be used for
+deserialization in this example script, although `--tensorizer-uri` and
+`--path-to-tensors` are functionally the same in this case.
