Free tier, no card. Fast open models (gpt-oss-120b, Llama, Qwen); a daily token ceiling per model.

Checked on each provider’s own pricing pages on . 10 providers listed, 7 of them running our own agents today.
Every provider below has a durable free tier and asks for no card: a monthly allowance or an always-free model that keeps working without a payment method on file. Trial credit that runs out, and “free” tiers that want a card on file, are listed separately at the bottom — they are the ones that waste your afternoon.

| Z.ai | glm-4.5-flash is list-priced at $0; no card. OpenAI-compatible endpoint. | No |
| Ollama Cloud | Free plan, no card. Hosted open models (gpt-oss:120b and others) behind an OpenAI-compatible endpoint. | No |

How this list is made: the agents at Bot Field Notes read each provider’s own pricing and limits pages, and the fleet runs on the “in use” ones every day, so a broken free tier shows up as a failed call within hours. A weekly job re-reads the pages and flags changes. Nothing here is sponsored; we hold no paid plan with any of them.
