# OpenGPT
`OpenGPT` is an open-source _cloud-native_ large **multi-modal models** (LMMs) serving solution.
It is designed to simplify the deployment and management of large language models, on a distributed cluster of GPUs.
> The content of README.md is just a placeholder to remind me of what I want to do.
## Features
OpenGPT provides the following features to make it easy to deploy and serve large multi-modal models (LMMs) in production:
- Support for multi-modal models
- Scalable architecture for handling high traffic loads
- Optimized for low-latency inference
- Automatic model partitioning and distribution across multiple GPUs
- Centralized model management and monitoring
- REST API for easy integration with existing applications
You can learn more about OpenGPT’s [architecture in our documentation](https://opengpt.readthedocs.io/en/latest/).
## Roadmap
You can view our roadmap with features that are planned, started, and completed on the [Roadmap discussion](discussions/categories/roadmap) category.
## Installation
Install the package with pip:
```bash
pip install open_gpt
```
## Quickstart
```python
import open_gpts
model = open_gpts.create_model('facebook/llama-7b', device='cuda', precision='fp16')
prompt = "The quick brown fox jumps over the lazy dog."
output = model.generate(
prompt,
max_length=100,
temperature=0.9,
top_k=50,
top_p=0.95,
repetition_penalty=1.2,
do_sample=True,
num_return_sequences=1,
)
```
We also provide some advanced features to allow you to host your models cost-effectively:
- **Offloading**: you can offload parts of the model to CPU to reduce the cost of inference.
- **Quantization**: you can quantize the model to reduce the cost of inference.
For more details, please see the [documentation](https://opengpt.readthedocs.io/en/latest/).
## Serving Models
You can serve your models with OpenGPT. To do so, you can use the `serve` command:
```bash
opengpt serve facebook/llama-9b --device cuda --precision fp16 --port 5000
```
This will start a server on port 5000. You can then send requests to the server:
```python
import requests
prompt = "The quick brown fox jumps over the lazy dog."
response = requests.post(
"http://localhost:5000/generate",
json={
"prompt": prompt,
"max_length": 100,
"temperature": 0.9,
"top_k": 50,
"top_p": 0.95,
"repetition_penalty": 1.2,
"do_sample": True,
"num_return_sequences": 1,
},
)
# SSE support
from aiohttp_sse_client import client as sse_client
async with sse_client.EventSource(
'http://localhost:5000/stream/generate?prompt=The+quick+brown+fox+jumps+over+the+lazy+dog.&max_length=100&temperature=0.9&top_k=50&top_p=0.95&repetition_penalty=1.2&do_sample=True&num_return_sequences=1'
) as event_source:
try:
async for event in event_source:
print(event)
except ConnectionError:
pass
```
Note that the server will only accept requests from the same machine. If you want to accept requests from other machines, you can use the `--host` flag to specify the host to bind to.
## Deploying Models
You can also deploy the server to a cloud provider like Jina Cloud or AWS.
To do so, you can use `deploy` command:
- Jina Cloud
```bash
opengpt deploy facebook/llama-9b --device cuda --precision fp16 --provider jina --name opengpt --replicas 2
```
- AWS
To deploy to AWS, you need to install extra dependencies:
```bash
pip install opegpt[aws]
```
And you need to specify the region:
```bash
opengpt deploy facebook/llama-9b --device cuda --precision fp16 --provider aws --region us-east-1 --name opengpt --replicas 2
```
This will deploy the model to the cloud provider. You can then send requests to the server:
```python
import requests
prompt = "The quick brown fox jumps over the lazy dog."
response = requests.post(
"https://opengpt.jina.ai/generate",
json={
"prompt": prompt,
"max_length": 100,
"temperature": 0.9,
"top_k": 50,
"top_p": 0.95,
"repetition_penalty": 1.2,
"do_sample": True,
"num_return_sequences": 1,
},
)
```
## Kubernetes
To deploy OpenGPT on your Kubernetes cluster, follow these steps:
1. Install the OpenGPT operator on your Kubernetes cluster using Helm:
```bash
helm install opengpt ./helm/opengpt --namespace opengpt
```
2. Create a custom resource for your GPT model:
```YAML
apiVersion: opengpt.io/v1alpha1
kind: GptModel
metadata:
name: my-gpt-model
namespace: opengpt
spec:
modelPath: s3://my-bucket/my-model
modelName: my-model
maxBatchSize: 16
inputShape:
- 1024
- 1024
- 3
outputShape:
- 1024
- 1024
- 3
```
3. Apply the custom resource to your cluster:
```bash
kubectl apply -f my-gpt-model.yaml
```
4. Monitor the status of your GPT model using the OpenGPT dashboard:
```bash
kubectl port-forward -n opengpt svc/opengpt-dashboard 8080:80
```
## Accessing models via API
You can also access the online models via API. To do so, you can use the `inference_client` package:
```python
from inference_client import Client
client = Client(token='<your access token>')
model = client.get_model('facebook/llama-9b')
prompt = "The quick brown fox jumps over the lazy dog."
output = model.generate(
prompt,
max_length=100,
temperature=0.9,
top_k=50,
top_p=0.95,
repetition_penalty=1.2,
do_sample=True,
num_return_sequences=1,
)
```
By this way, you can access the models without deploying them to your own machine.
## Advanced Usage
### Model Offloading
You can also apply the model offloading techniques (based on [FlexTensor](https://github.com/numb3r3/flex-tensor)) to OpenGPT. To do so, you can use the `--offload-percents` flag:
```bash
opengpt serve facebook/llama-9b --device cuda --precision fp16 --port 5000 --offload-percents 10,90,50,50,0,100
```
This will offload parts of the model to the CPU. You can also use the `--offload-strategy` flag to specify the offloading strategy:
```bash
opengpt serve facebook/llama-9b --device cuda --precision fp16 --port 5000 --offload-strategy "cpu,cpu,cpu,cpu,cpu,cpu"
```
### Model Quantization
You can also apply the model quantization techniques.
- 8-bit quantization
```bash
opengpt serve facebook/llama-9b --device cuda --precision fp16 --port 5000 --quantize 8bit
```
## Fine-tuning Models
We currently support fine-tuning models by using the `finetune` command:
```bash
opengpt finetune facebook/llama-9b --dataset wikitext-2 --device cuda --precision fp16 --batch-size 32 --learning-rate 1e-4 --epochs 10
```
Specifically, we implement the following fine-tuning methods:
- [LLaMA-Adapter: Efficient Fine-tuning of LLaMA](https://github.com/ZrrSkywalker/LLaMA-Adapter): Fine-tuning model to follow instructions within 1 Hour and 1.2M Parameters
- [low-rank adaptation (LoRA)](https://arxiv.org/pdf/2106.09685.pdf): Low-Rank Adaptation for Efficient Language Model Fine-Tuning

If You\n institute patent litigation against any entity (including a\n cross-claim or counterclaim in a lawsuit) alleging that the Work\n or a Contribution incorporated within the Work constitutes direct\n or contributory patent infringement, then any patent licenses\n granted to You under this License for that Work shall terminate\n as of the date such litigation is filed.\n\n 4. Redistribution. You may reproduce and distribute copies of the\n Work or Derivative Works thereof in any medium, with or without\n modifications, and in Source or Object form, provided that You\n meet the following conditions:\n\n (a) You must give any other recipients of the Work or\n Derivative Works a copy of this License; and\n\n (b) You must cause any modified files to carry prominent notices\n stating that You changed the files; and\n\n (c) You must retain, in the Source form of any Derivative Works\n that You distribute, all copyright, patent, trademark, and\n attribution notices from the Source form of the Work,\n excluding those notices that do not pertain to any part of\n the Derivative Works; and\n\n (d) If the Work includes a \"NOTICE\" text file as part of its\n distribution, then any Derivative Works that You distribute must\n include a readable copy of the attribution notices contained\n within such NOTICE file, excluding those notices that do not\n pertain to any part of the Derivative Works, in at least one\n of the following places: within a NOTICE text file distributed\n as part of the Derivative Works; within the Source form or\n documentation, if provided along with the Derivative Works; or,\n within a display generated by the Derivative Works, if and\n wherever such third-party notices normally appear. The contents\n of the NOTICE file are for informational purposes only and\n do not modify the License. You may add Your own attribution\n notices within Derivative Works that You distribute, alongside\n or as an addendum to the NOTICE text from the Work, provided\n that such additional attribution notices cannot be construed\n as modifying the License.\n\n You may add Your own copyright statement to Your modifications and\n may provide additional or different license terms and conditions\n for use, reproduction, or distribution of Your modifications, or\n for any such Derivative Works as a whole, provided Your use,\n reproduction, and distribution of the Work otherwise complies with\n the conditions stated in this License.\n\n 5. Submission of Contributions. Unless You explicitly state otherwise,\n any Contribution intentionally submitted for inclusion in the Work\n by You to the Licensor shall be under the terms and conditions of\n this License, without any additional terms or conditions.\n Notwithstanding the above, nothing herein shall supersede or modify\n the terms of any separate license agreement you may have executed\n with Licensor regarding such Contributions.\n\n 6. Trademarks. This License does not grant permission to use the trade\n names, trademarks, service marks, or product names of the Licensor,\n except as required for reasonable and customary use in describing the\n origin of the Work and reproducing the content of the NOTICE file.\n\n 7. Disclaimer of Warranty. Unless required by applicable law or\n agreed to in writing, Licensor provides the Work (and each\n Contributor provides its Contributions) on an \"AS IS\" BASIS,\n WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or\n implied, including, without limitation, any warranties or conditions\n of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A\n PARTICULAR PURPOSE. You are solely responsible for determining the\n appropriateness of using or redistributing the Work and assume any\n risks associated with Your exercise of permissions under this License.\n\n 8. Limitation of Liability. In no event and under no legal theory,\n whether in tort (including negligence), contract, or otherwise,\n unless required by applicable law (such as deliberate and grossly\n negligent acts) or agreed to in writing, shall any Contributor be\n liable to You for damages, including any direct, indirect, special,\n incidental, or consequential damages of any character arising as a\n result of this License or out of the use or inability to use the\n Work (including but not limited to damages for loss of goodwill,\n work stoppage, computer failure or malfunction, or any and all\n other commercial damages or losses), even if such Contributor\n has been advised of the possibility of such damages.\n\n 9. Accepting Warranty or Additional Liability. While redistributing\n the Work or Derivative Works thereof, You may choose to offer,\n and charge a fee for, acceptance of support, warranty, indemnity,\n or other liability obligations and/or rights consistent with this\n License. However, in accepting such obligations, You may act only\n on Your own behalf and on Your sole responsibility, not on behalf\n of any other Contributor, and only if You agree to indemnify,\n defend, and hold each Contributor harmless for any liability\n incurred by, or claims asserted against, such Contributor by reason\n of your accepting any such warranty or additional liability.\n\n END OF TERMS AND CONDITIONS\n\n Copyright 2020-2022 Jina AI Limited\n\n Licensed under the Apache License, Version 2.0 (the \"License\");\n you may not use this file except in compliance with the License.\n You may obtain a copy of the License at\n\n http://www.apache.org/licenses/LICENSE-2.0\n\n Unless required by applicable law or agreed to in writing, software\n distributed under the License is distributed on an \"AS IS\" BASIS,\n WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied.\n See the License for the specific language governing permissions and\n limitations under the License.\n",
