How to Build a Multi-Model AI App with One API

Stop juggling 5+ API providers. One key, all models, 40% cheaper.

Building AI apps in 2026 means choosing between dozens of models. DeepSeek for reasoning. Kimi for long documents. GLM for Chinese. Qwen for code. Doubao for speed. Each requires a separate account, API key, billing system, and SDK.

I spent 2 hours per week just managing keys and tracking usage across providers. Then I built TokenEase.

The Problem: Subscription Sprawl

To build a serious AI product, you need access to multiple models:

6 vendors. 6 API keys. 6 billing systems. 6 SDK patterns (almost-same-but-not-quite).

The Solution: One Unified API

TokenEase is a single API gateway that aggregates 7 top AI models behind one OpenAI-compatible interface.

curl https://tokenease.io/v1/chat/completions \\
  -H "Authorization: Bearer YOUR_KEY" \\
  -H "Content-Type: application/json" \\
  -d '{
    "model": "deepseek-chat",
    "messages": [{"role": "user", "content": "Hello"}]
  }'

Switch models with one parameter change:

# DeepSeek for coding
"model": "deepseek-chat"

# Kimi K3 for long documents (200K context)
"model": "kimi-k3"

# GLM-5.1 for Chinese
"model": "glm-5"

# Qwen-Plus for reasoning
"model": "qwen-plus"

# Doubao Pro for speed
"model": "doubao-pro"
