# OpenLLM
|
|
|
|
This page demonstrates how to use [OpenLLM](https://github.com/bentoml/OpenLLM)
|
|
with LangChain.
|
|
|
|
`OpenLLM` is an open platform for operating large language models (LLMs) in
|
|
production. It enables developers to easily run inference with any open-source
|
|
LLMs, deploy to the cloud or on-premises, and build powerful AI apps.
|
|
|
|
## Installation and Setup
|
|
|
|
Install the OpenLLM package via PyPI:
|
|
|
|
```bash
|
|
pip install openllm
|
|
```
|
|
|
|
## LLM
|
|
|
|
OpenLLM supports a wide range of open-source LLMs as well as serving users' own
|
|
fine-tuned LLMs. Use `openllm model` command to see all available models that
|
|
are pre-optimized for OpenLLM.
|
|
|
|
## Wrappers
|
|
|
|
There is a OpenLLM Wrapper which supports loading LLM in-process or accessing a
|
|
remote OpenLLM server:
|
|
|
|
```python
|
|
from langchain.llms import OpenLLM
|
|
```
|
|
|
|
### Wrapper for OpenLLM server
|
|
|
|
This wrapper supports connecting to an OpenLLM server via HTTP or gRPC. The
|
|
OpenLLM server can run either locally or on the cloud.
|
|
|
|
To try it out locally, start an OpenLLM server:
|
|
|
|
```bash
|
|
openllm start flan-t5
|
|
```
|
|
|
|
Wrapper usage:
|
|
|
|
```python
|
|
from langchain.llms import OpenLLM
|
|
|
|
llm = OpenLLM(server_url='http://localhost:3000')
|
|
|
|
llm("What is the difference between a duck and a goose? And why there are so many Goose in Canada?")
|
|
```
|
|
|
|
### Wrapper for Local Inference
|
|
|
|
You can also use the OpenLLM wrapper to load LLM in current Python process for
|
|
running inference.
|
|
|
|
```python
|
|
from langchain.llms import OpenLLM
|
|
|
|
llm = OpenLLM(model_name="dolly-v2", model_id='databricks/dolly-v2-7b')
|
|
|
|
llm("What is the difference between a duck and a goose? And why there are so many Goose in Canada?")
|
|
```
|
|
|
|
### Usage
|
|
|
|
For a more detailed walkthrough of the OpenLLM Wrapper, see the
|
|
[example notebook](/docs/modules/model_io/models/llms/integrations/openllm.html)
