Free AI Models

Free models are for experimenting, learning and shipping without a bill — AIHubMix covers the inference cost for all 49 models on this page, and every model answers all three protocols: Chat Completions, Messages and Responses. Every account starts with 10 trial calls, no credit card, and a $1 top-up switches you to permanent daily quotas.

Rate limit shows the daily and per-minute request caps for topped-up accounts. Some models carry a higher request weight — one call counts as several requests — which is why their caps are lower. All free models share one pool of 1M tokens per day. Before your first top-up, the 10 trial calls apply instead. Context “—” means the value is not published in the catalog. Modalities read input → output — the same fact the developer pages show; a missing output side means the catalog does not publish it, not that the model returns nothing.

A -free ID like coding-glm-5.2-free — the most-called free model this month — is the same upstream model as coding-glm-5.2, served as a subsidized free variant. Swap the suffix off when you need paid throughput; nothing else in your code changes.

Free Models on AIHubMix

Are these models really free?

Yes. All 49 models bill $0 for input and output tokens. AIHubMix subsidizes the inference cost; usage is bounded by quotas instead of a bill.

What do I get before topping up?

10 trial calls, shared across all free models, with no expiry. When they run out the API keeps answering with a note that the trial is used up — your integration never sees a hard error.

What do I get after topping up?

Any top-up of $1 or more permanently switches your account to daily quotas: 10 requests per minute, 100 requests per day and 1M tokens per day, shared across the free catalog and reset every day. Models with a higher request weight count as several requests per call — the exact caps are in the table. Past a cap the API returns 429 until the next minute or day starts.

What is the difference between coding-glm-5.2-free and coding-glm-5.2?

Price is the only difference — they are the same upstream model with identical capability. The -free ID bills $0 within the quotas above; the paid ID bills per token with no daily cap. Switching between them is a one-line model-name change.
