EvoLink

Overview

EvoLink.ai is a tool that lets developers use lots of AI models through one API. That covers stuff like text, images, video and sound. No need to mess with different vendors or keep up with multiple keys and pricing systems.

You can just use one key and hit models from OpenAI, Google, Alibaba, BytePlus and others. It also picks the cheapest or fastest option each time which helps cut down costs. They say you might save 20 to 70 percent this way.

It’s made for people building apps with AI who want things simple and not crazy expensive.

What it offers
All-in-one access. One API key gets you a bunch of models for text, images, and video.
Works across types. That includes GPT-5.x, Claude, Gemini, plus image tools like Nano Banana, Qwen Image Edit, and video tools like Sora 2 Pro and Seedance. There’s even some music stuff like Suno.
Smarter routing. It checks which option is cheaper or quicker and sends your request there.
No lock-in. You just pay as you go, no monthly plan.
Stays up. If one provider fails it swaps to another, so you’re rarely down.
Dev-friendly. It uses OpenAI-style setup, so switching’s not a pain. You also get SDKs in popular languages.

Who it's for
👉 Startups and apps wanting to add AI features fast
👉 SaaS products that need AI but can’t guess monthly costs
👉 Big companies trying to spend less on AI
👉 Content platforms making stuff with text, pics, or video

How pricing works
No fixed plans or monthly charges. You pay for what you use. Each model has its own rate, billed by token, request, image or seconds of video.

Usually cheaper than going straight to the model provider, since EvoLink picks the lowest-cost option in the background. New users often get some free credits to try things out.

Example: some image tools cost a tiny fraction per picture... video can be a few cents or more per second, depending on what you use.
