openai just dropped free models. you can now stop paying for chatgpt.
they're called gpt-oss. 2 versions: 20b and 120b (that’s billion with a b). and yes, they can think, reason, and talk just like gpt. crazy.
you can plug them into your automations in n8n and never pay api costs again.
2 ways to do it 👇
method 1 – huggingface + curl
- go to huggingface.com
- search “gpt-oss” models
- grab the curl command (it’s under “deploy → inference API”)
- paste it into n8n using the http request node
- drop your huggingface token in
- done. you’re live.
method 2 – groq (free llm provider)
- sign up at groq.com
- get an api key (starts with sk-)
- open n8n, use the ai agent node
- choose groq as provider
- paste your key
- choose gpt-oss or another model (i like llama3 too)
- set temperature to 0.7 (sweet spot for smart + creative)
bonus tip: you can make a public ai chat with this setup. free chatbot. no fees. no limits.
hope this helps!
