Connect Models via PPIO LLM API

FastGPT can also connect models through the PPIO LLM API.

FastGPT is a platform that simplifies the entire AI development, deployment, and usage workflow into visual operations. Developers don't need to dive deep into algorithms, and users don't need to master complex technologies — it turns AI into an easy-to-use tool through a one-stop service.

PPIO Cloud provides simple and easy-to-use API interfaces that allow developers to easily call models like DeepSeek.

• For developers: No need to restructure your architecture. Complete integration for all scenarios from text generation to decision reasoning with just 3 interfaces — design AI workflows like building blocks.
• For the ecosystem: Automatically adapts resource requirements from small applications to enterprise systems, letting intelligence grow naturally with your business.

The tutorial below provides a complete integration guide (including key configuration) to help you quickly connect FastGPT with the PPIO API.

1. Prerequisites

(1) Get the API endpoint

Fixed at: https://api.ppinfra.com/v3/openai/chat/completions.

(2) Get the API Key

Log in to the PPIO Cloud console API Key Management page and click the create button. Use invitation code [VOJL20] when registering to receive a 50 yuan voucher.

(3) Generate and save the API Key

(4) Get the model IDs you need

DeepSeek series:

• DeepSeek R1: deepseek/deepseek-r1/community

• DeepSeek V3: deepseek/deepseek-v3/community

For other model IDs, max context, and pricing, see: Model List

2. Deploy the Latest FastGPT to Your Local Environment

3. Model Configuration (Choose One of the Two Methods Below)

(1) Connect PPIO models via OneAPI: Refer to the OneAPI documentation to update FastGPT environment variables. After generating a token in One API, FastGPT can send requests to One API by modifying the baseurl and key, and One API will forward them to the appropriate models. Update these two environment variables (make sure to include v1; if on the same network, you can use the internal address):

OPENAI_BASE_URL= http://OneAPI-IP:OneAPI-PORT/v1

The key below is the token provided by One API: CHAT_API_KEY=sk-UyVQcpQWMU7ChTVl74B562C28e3c46Fe8f16E6D8AeF8736e

• After restarting FastGPT, select PPIO Cloud in the model providers as shown below:

• Test connectivity Using DeepSeek as an example, select deepseek/deepseek-r1/community in the model list, click the position marked 2 in the image to test connectivity. A green success indicator confirms the connection is working and you can proceed with configuring conversations.

(2) Connect PPIO models without OneAPI

Select PPIO Cloud in the model providers as shown below:

• Configure the model: Enter https://api.ppinfra.com/v3/openai/chat/completions in the custom request URL field.

  

• Test connectivity

  

A green success indicator confirms the connection is working and you can proceed with configuring conversations.

4. Configure Conversations

(1) Create a new workspace

(2) Start chatting
