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 (thatโs 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 ๐ method 1 โ huggingface + curl - go to huggingface.com - search โgpt-ossโ models - grab the curl command (itโs under โdeploy โ inference APIโ) - paste it into n8n using the http request node - drop your huggingface token in - done. youโre live. method 2 โ 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!
