✨ Supportted backends

• chatgpt: openai's official ChatGPT interface
• gpt3: openai's official GPT-3 interface
• gpt-embedding: openai's official Embedding interface
• dall-e: openai's official DALL·E interface
• welm: wechat's llm interface
• newbing: New Bing search based on ChatGPT（unofficial)

⏳ WIP

• llama
• stable diffusion
• controlNet
• SAM(meta)

Install & Run

1. run locally

# python >= 3.8
python3 -m pip install -r requirements.txt

python3 run_api_server.py

2. run with docker

./build_docker.sh
./start_docker.sh

Visit server

1. Use the curl command to access:

# 1. Start a new session
curl -X POST -H "Content-Type: application/json" -d '{"bot_type":"mock"}' http://127.0.0.1:5050/v1/chat/start
# response sample: {"code":0,"msg":"Success","session":"123456"}

# 2. chat with LLMs
curl -X POST -H "Content-Type: application/json" -d '{"session":"123456","content":"hello"}' http://127.0.0.1:5050/v1/chat/ask
# response sample: {"code":0,"msg":"Success","reply":"Text mock reply for your prompt:hello","timestamp":1678865301.0842562}

# 3. Close the session and end chat
curl -X POST -H "Content-Type: application/json" -d '{"session":"123456"}' http://127.0.0.1:5050/v1/chat/end
# response: {"code":0,"msg":"Success"}

2. Using command line tools:llmapi_cli

llmapi_cli --host="http://127.0.0.1:5050" --bot=mock

3. Integrate in your python code with llmapi_cli module

from llmapi_cli import LLMClient

client = LLMClient(host = "http://127.0.0.1:5050", bot = "mock")

rep = client.ask("hello")

print(rep)

Plug into your LLM's backend !

1. You need to create a new backend name in the backend directory (assumed to be newllm), you can directly cp -r mock newllm
2. Referring to the implementation of mock, change the backend name to newllm
3. In the newllm directory, add the necessary dependencies, and all related development is bound to this directory
4. Add support for newllm in backend.py
