Integrate Open Source Models into Your Existing Apps Without Any Code Change

While many developers are utilizing the OpenAI GPT API to develop their applications, some may also wish to experiment with various open-source models. However, integrating different open-source models can be challenging due to the differences in their APIs and GPU requirements.

An approach that could help simplify the integration of open-source models is by making use of Modelz, a platform that offers OpenAI-compatible APIs for a variety of language models. By utilizing Modelz, developers can seamlessly switch between different language models without needing to make significant changes to their code.

Use open-source LLMs in SkyAGI

I'd be happy to illustrate how Modelz could simplify the workflow for integrating different open-source models using SkyAGI as an example.

SkyAGI is a python package that showcases the emerging capability of LLMs in simulating believable human behaviors. SkyAGI implements the idea of Generative Agents and delivers a role-playing game that creates a very interesting user experience.

SkyAGI utilizes LangChain and OpenAI API to generate the characters' outputs. However, if a developer wishes to experiment with different open-source models, they would need to modify the code to integrate the new models and their respective APIs. This process can be challenging and time-consuming.

Alternatively, developers can deploy a OpenAI compatible API instance on Modelz, then just replace OpenAI_API_BASE and OPENAI_API_KEY to use the instance on Modelz.

export OpenAI_API_BASE=
# Use your API key on Modelz
export OPENAI_API_KEY=mzi-abcdefg...

Or you could declare the base host and api key with OpenAI python package:

import openai

Use local deployed instance

It also works if you want to run the server locally. You could just install our open-source python package modelz-llm and start it locally:

pip install modelz-llm
modelz-llm -m bigscience/bloomz-560m --device cpu

Then you could set the environment variables to your local deployed instance:

export OpenAI_API_BASE=http://localhost:8080
# Use your API key on Modelz
export OPENAI_API_KEY=mzi-abcdefg...


Our open-source project, modelz-llm, supports the OpenAI-compatible API, providing developers with a platform to experiment with various language models seamlessly. With the help of modelz-llm, developers can easily switch between different language models without requiring significant code changes and take advantage of the compatible API. You could deploy it on Modelz with just one click, or just use it locally.

Furthermore, we welcome contributions to the project, which could help improve its functionality, expand its capabilities, and make it an even more valuable resource for developers. Our community is always looking for enthusiasts to help in all different ways:
