OpenLLM lets developers run any **open-source LLMs** as **OpenAI-compatible API** endpoints with **a single command**.
- 🔬 Build for fast and production usages
- đźš‚ Support llama3, qwen2, gemma, etc, and many **quantized** versions [full list](https://github.com/bentoml/openllm-models)
- ⛓️ OpenAI-compatible API
- 💬 Built-in ChatGPT like UI
- 🔥 Accelerated LLM decoding with state-of-the-art inference backends
- 🌥️ Ready for enterprise-grade cloud deployment (Kubernetes, Docker and BentoCloud)
## Get Started
```bash
pip install openllm # or pip3 install openllm
openllm hello
```
to explore models interactively. It will guide you to run LLMs locally or deploy to cloud.
## Supported models
OpenLLM supports a variety of state-of-the-art LLMs. Here are some of the models supported by OpenLLM, each listed with a commonly used model size.
| Model | Parameters | Quantinize | Required GPU | Start a Server |
| --------- | ---------- | ---------- | ------------- | --------------------------------- |
| Llama 3.1 | 8B | - | 24G | `openllm serve llama3.1:8b` |
| Llama 3.1 | 8B | AWQ 4bit | 12G | `openllm serve llama3.1:8b-4bit` |
| Llama 3.1 | 70B | AWQ 4bit | 80G | `openllm serve llama3.1:70b-4bit` |
| Llama 2 | 7B | - | 16G | `openllm serve llama2:7b` |
| Llama 2 | 7B | AWQ 4bit | 12G | `openllm serve llama2:7b-4bit` |
| Mistral | 7B | - | 24G | `openllm serve mistral:7b` |
| Qwen2 | 1.5B | - | 12G | `openllm serve qwen2:1.5b` |
| Gemma | 7B | - | 24G | `openllm serve gemma:7b` |
| Phi3 | 3.8B | - | 12G | `openllm serve phi3:3.8b` |
...
For the full model list, see the [OpenLLM models repository](https://github.com/bentoml/openllm-models).
## Start an LLM server
To start an LLM server locally, use the `openllm serve` command and specify the model version.
```bash
openllm serve llama3:8b
```
The server will be accessible at [http://localhost:3000](http://localhost:3000/), providing OpenAI-compatible APIs for interaction. You can call the endpoints with different frameworks and tools that support OpenAI-compatible APIs. Typically, you may need to specify the following:
- **The API host address**: By default, the LLM is hosted at [http://localhost:3000](http://localhost:3000/).
- **The model name:** The name can be different depending on the tool you use.
- **The API key**: The API key used for client authentication. This is optional.
Here are some examples:
OpenAI Python client
```python
from openai import OpenAI
client = OpenAI(base_url='http://localhost:3000/v1', api_key='na')
# Use the following func to get the available models
# model_list = client.models.list()
# print(model_list)
chat_completion = client.chat.completions.create(
model="meta-llama/Meta-Llama-3-8B-Instruct",
messages=[
{
"role": "user",
"content": "Explain superconductors like I'm five years old"
}
],
stream=True,
)
for chunk in chat_completion:
print(chunk.choices[0].delta.content or "", end="")
```
LlamaIndex
```python
from llama_index.llms.openai import OpenAI
llm = OpenAI(api_bese="http://localhost:3000/v1", model="meta-llama/Meta-Llama-3-8B-Instruct", api_key="dummy")
...
```
## Chat UI
OpenLLM provides a chat user interface (UI) at the `/chat` endpoint for an LLM server. You can visit the chat UI at http://localhost:3000/chat and start different conversations with the model.
## Chat with a model in the CLI
To start a chat conversation in the CLI, use the `openllm run` command and specify the model version.
```bash
openllm run llama3:8b
```
## Model repository
A model repository in OpenLLM represents a catalog of available LLMs that you can run. OpenLLM provides a default model repository that includes the latest open-source LLMs like Llama 3, Mistral, and Qwen2, hosted at [this GitHub repository](https://github.com/bentoml/openllm-models). To see all available models from the default and any added repository, use:
```bash
openllm model list
```
To ensure your local list of models is synchronized with the latest updates from all connected repositories, run:
```bash
openllm repo update
```
To review a model’s information, run:
```bash
openllm model get llama3:8b
```
### Add a model to the default model repository
You can contribute to the default model repository by adding new models that others can use. This involves creating and submitting a Bento of the LLM. For more information, check out this [example pull request](https://github.com/bentoml/openllm-models/pull/1).
### Set up a custom repository
You can add your own repository to OpenLLM with custom models. To do so, follow the format in the default OpenLLM model repository with a `bentos` directory to store custom LLMs. You need to [build your Bentos with BentoML](https://docs.bentoml.com/en/latest/guides/build-options.html) and submit them to your model repository.
First, prepare your custom models in a `bentos` directory following the guidelines provided by [BentoML to build Bentos](https://docs.bentoml.com/en/latest/guides/build-options.html). Check out the [default model repository](https://github.com/bentoml/openllm-repo) for an example and read the [Developer Guide](https://github.com/bentoml/OpenLLM/blob/main/DEVELOPMENT.md) for details.
Then, register your custom model repository with OpenLLM:
```bash
openllm repo add
```
**Note**: Currently, OpenLLM only supports adding public repositories.
## Deploy to BentoCloud
OpenLLM supports LLM cloud deployment via BentoML, the unified model serving framework, and BentoCloud, an AI inference platform for enterprise AI teams. BentoCloud provides fully-managed infrastructure optimized for LLM inference with autoscaling, model orchestration, observability, and many more, allowing you to run any AI model in the cloud.
[Sign up for BentoCloud](https://www.bentoml.com/) for free and [log in](https://docs.bentoml.com/en/latest/bentocloud/how-tos/manage-access-token.html). Then, run `openllm deploy` to deploy a model to BentoCloud:
```bash
openllm deploy llama3:8b
```
Once the deployment is complete, you can run model inference on the BentoCloud console:
