I got tired of managing 5+ API keys just to let users choose their favorite LLM.
So I built AIBridge — one API key, 14+ models, OpenAI-compatible format.
The Problem
If you've built an AI feature, you probably know this pain:
OpenAI key for GPT-4
Anthropic key for Claude
DeepSeek key for... DeepSeek
Qwen key for Alibaba models
GLM key for Zhipu models
Each has a different API format. Each needs separate error handling. Each has different rate limits.
The Solution
AIBridge sits in front of all these providers and gives you one unified API:
from openai import OpenAI
Same code, different model
client = OpenAI(
api_key="your_aibridge_key",
base_url="https://aibridge-api.com/v1",
)
DeepSeek V4 Pro
response = client.chat.completions.create(
model="deepseek-v4-pro",
messages=[{"role": "user", "content": "Hello!"}],
)
Qwen Max (just change the model name!)
response = client.chat.completions.create(
model="qwen-max",
messages=[{"role": "user", "content": "Hello!"}],
)
That's it. No new SDK. No format conversion. Just change the model name.
Works with LangChain out of the Box
from langchain_openai import ChatOpenAI
llm = ChatOpenAI(
model="deepseek-v4-pro",
openai_api_key="your_aibridge_key",
openai_api_base="https://aibridge-api.com/v1",
)
llm.invoke("Explain quantum computing in 3 sentences")
Supported Models
Provider Models
DeepSeek V4 Pro 🔥, V4 Flash, V3, Coder
Qwen Max, Plus, Qwen3 235B
GLM-4 Plus, Air, Flash
Kimi 8K, 32K, 128K
And growing — new models added regularly.
Pricing (Why It Matters)
Free: 500K tokens/month
Pro: $9.90/month for 5M tokens
Top-up: $2.99 for 1M tokens (one-time, never expires)
Compare that to managing separate API keys where you're billed separately for each provider.

Done.

Why I'm Sharing This
I built this because I needed it for my own projects. If it saves you time, great. If you have feedback or feature requests, drop a comment — I read every one.
Happy building! 🚀
