OpenRouter free tier in under a minute: about twenty free AI models with no card, the daily and per-minute limits, the one-time ten dollar upgrade, and the three traps where free access breaks: provider 429s, a small max_tokens and a negative balance.
OpenRouter free tier in under a minute
Recorded on 13 September 2026. The video deliberately names no model: the free roster changes week to week, and the list in the guide is re-tested every day.
The video is the short version. The numbers behind it are kept current in the guide:
OpenRouter Free Tier 2026: Rate Limits, Free Models TestedThe three traps, in text
What the video warns about, with the error you actually see.
429
The provider behind that free model is saturated. Your own quota is untouched, and the error names the provider.
Ask for openrouter/free, or keep a fallback list of two or three :free models from different providers.
402
Your credit balance is below zero. OpenRouter then refuses free models too, not only paid ones.
Top the balance back above zero. One cent negative from a paid test is enough to stop everything.
Empty answer
Free models reason before they reply, and the reasoning is billed to max_tokens. A small budget is spent thinking, leaving nothing for the answer.
Raise max_tokens. A one-number reply cost between 7 and 390 completion tokens in our test.
