Replaced $40/month in AI API subscriptions with self-hosted Ollama + n8n (discuss.tchncs.de)

Quick post about a change I made that's worked out well.

I was using OpenAI API for automations in n8n — email summaries, content drafts, that kind of thing. Was spending ~$40/month.

Switched everything to Ollama running locally. The migration was pretty straightforward since n8n just hits an HTTP endpoint. Changed the URL from api.openai.com to localhost:11434 and updated the request format.

For most tasks (summarization, classification, drafting) the local models are good enough. Complex reasoning is worse but I don't need that for automation workflows.

Hardware: i7 with 16GB RAM, running Llama 3 8B. Plenty fast for async tasks.

What whack ass setup so you think OP has? Dual 5090s? They’re running it on an i7.

It's also an 8 gigaparameter model. That's pretty tiny, even if they use it heaps.
