Aider

Use Aider with any of 200+ models through Chuizi.AI via the OpenAI or Anthropic protocol.

Prerequisites

Aider installed (pip install aider-chat)
A Chuizi.AI account with an API key (starts with ck-)

OpenAI Protocol (Recommended)

Use this configuration to access any model through the OpenAI-compatible endpoint.

Set the environment variables:

terminal

bash

export OPENAI_API_BASE=https://api.chuizi.ai/v1
export OPENAI_API_KEY=ck-your-key-here

Then start Aider with your preferred model:

terminal

bash

# Claude Sonnet
aider --model openai/anthropic/claude-sonnet-4-6

# GPT-4.1
aider --model openai/openai/gpt-4.1

# DeepSeek
aider --model openai/deepseek/deepseek-chat

Note: When using the OpenAI protocol, prefix the model name with openai/ to tell Aider to use the OpenAI API format, followed by the Chuizi.AI model name (e.g., openai/anthropic/claude-sonnet-4-6).
