One API Key, 15+ Models: A Better Way to Call Every Major LLM

Here's the state of building with LLMs in 2026: DeepSeek has one API, Moonshot has another, Zhipu GLM has a third, Alibaba's Qwen a fourth. Each with its own key, its own SDK quirks, its own billing console, its own free-tier rules.

We built AIBridge to collapse all of that into one OpenAI-compatible endpoint, one API key, one billing account.

What you get

🗝️ One key, every model

AIBridge speaks the OpenAI protocol. If your code already uses openai SDK, you switch by changing two lines — the base_url and the key. Then every model is one parameter away:

from openai import OpenAI

client = OpenAI(
    base_url="https://aibridge-api.com/v1",
    api_key="mb-your-key",
)

# Budget chat
r = client.chat.completions.create(
    model="deepseek-chat", messages=[{"role": "user", "content": "summarize this"}],
)

# Switch to a reasoning model by changing one string
r = client.chat.completions.create(
    model="kimi-k3", messages=[{"role": "user", "content": "a hard reasoning task"}],
)

# Embeddings, same key
e = client.embeddings.create(model="qwen-plus", input=["hello world"])

No new SDKs. No per-provider key management. No vendor lock-in.

⚡ Streaming everywhere

All models support streaming responses. Build chat UIs, agents, and live assistants without touching provider-specific streaming formats.

🎁 A real free tier

Register and get 500K tokens every month, reset automatically. Enough to prototype, build a side project, or evaluate models before committing. No credit card required.

📦 Pay for what you actually need

When the free tier runs out, two options — no surprises:

Top-up packs: 1M tokens for 2.99,5M for9.90, 20M for $29.90. Raw tokens, 1:1. What you buy is what you get — no hidden multipliers, no expiration, no monthly reset stealing your balance.
Pro plan: $9.90/month for 5M monthly tokens, with higher rate limits.

🧪 Try before you register

The Playground lets you test any model right in the browser — free, a few requests a day, no account needed. Great for comparing K3 vs GLM-4-Plus vs DeepSeek side by side.

📊 Know exactly what you're spending

The dashboard shows your usage per model, current balance, and request history — so you always know which model is eating your quota and can switch to a cheaper one.

🔒 Privacy built in

Requests are automatically scanned and PII (names, emails, phone numbers) is redacted before it leaves your context. Your users' data stays yours.

Why a gateway at all?

Three reasons developers keep coming back:

Compare models instantly — the switching cost is one string, so you actually do benchmark instead of sticking with the first model you integrated.
One billing surface — one balance, one invoice, one place to see everything, instead of five vendor consoles.
Built-in failover — if one provider hiccups, the gateway routes around it and tracks model health for you.
