OpenAI Went Free, No More API Costs
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!
