:zzz: What the heck is this?

Tencent (yes, the billion-dollar Chinese tech giant) has an insane 80B AI model called Hunyuan-A13B.

They quietly made it 100% free through OpenRouter on July 12.
No press release. No party. No announcement. Just casually dropped like a mixtape no one asked for.

You can now use this beast for free—forever—through a clean, simple API.
Basically:

“Here, have ChatGPT on steroids… no credit card required.”

:hammer_and_wrench: How to use it (without melting your brain)

1. Go to OpenRouter.ai

Make a free account. They don’t want your money. Just your curiosity.

2. Get your API Key

Copy it like your life depends on it (or just paste it in Notepad).

3. Choose the model

Pick this one in the list:
tencent/hunyuan-a13b-instruct:free
(Yes, with the “:free” at the end. Don’t get cute.)

4. Paste your API key

Anywhere that supports OpenAI-style APIs. Playground, app, Postman, Python script, or… duct-taped spreadsheet. It just works.

:brain: How smart is it?

  • Model size: 80 Billion params
  • Memory span: 256,000 tokens (basically, it remembers that embarrassing DM from 3 years ago)
  • Type: MoE – Mixture of Experts (don’t worry, it means “super fast but not always awake”)
  • Price: Free.
    Not “free trial.” Not “free with ad tracking.” Just free.

:smiling_face_with_horns: Why is it free? What’s the catch?

Tencent is baiting developers like candy in a dark alley.

They want devs to play with it, build stuff, get hooked—and maybe someday… pay.
But right now? You’re in the honeymoon phase. Use it. Abuse it. Be that toxic ex who takes everything and leaves.

:wrapped_gift: Bonus Tricks You Should Totally Exploit

:white_check_mark: OpenRouter has lots of other free models—just search for “:free”
Example:

  • meta-llama/llama-3-8b-instruct:free
  • mistralai/mistral-7b-instruct:free
  • openchat/openchat-7b:free
    Use the same key. No extra signup. It’s like an AI buffet.

:white_check_mark: Got Vercel?
Boom, $5 free AI credits every month.
Enough to mess around with OpenAI, Anthropic, xAI, etc.
No servers. No crying. Just paste and go.

:white_check_mark: Hugging Face Inference API
Free model usage every month.
No setup, just use your token.
(And yes, it still sounds like a weird dating site.)

:warning: Does it actually work?

Yes. It works terrifyingly well.

  • Chatbots? :white_check_mark:
  • Longform writing? :white_check_mark:
  • Embedding your soul into prompts? Also :white_check_mark:

But don’t be a clown and spam it 24/7 or you’ll trigger rate limits.
This isn’t AWS. It’s a very generous vampire that hasn’t tasted blood… yet.

:headstone: Final Thought (Before This Gets “Discovered”)

This is the kind of stuff devs usually hide in Discord servers and whisper about.
It’s free. It’s fast. It’s Chinese. It remembers everything.
And almost no one’s using it because nobody reads changelogs anymore.

So use it before the rest of the internet wakes up.

Enjoy the silence while it lasts.
