What you get

IBM’s watsonx.ai Runtime on its Lite plan — 300,000 tokens a month of foundation-model inference (Granite, Llama, Mistral and other hosted models) on IBM Cloud, a plan IBM’s own docs call free and never bill

Free models

No free model family is currently listed here; callable ids, where the row has them, are under Connect.

Limits, in the vendor’s words

Lite: 300,000 tokens/month; 2 requests/second per service plan

Lite compute: 20 CUH/month per service plan

The Lite service plan has limited capacity and no published expiry. IBM Cloud signup requires personal and card information to verify identity; Lite plans do not incur charges. Its covered foundation models are listed separately. The compute allowance and inference-token budget measure different kinds of usage.

Where it is offered

Not offered in Vietnam, Türkiye, Taiwan, Nigeria, Ukraine, Egypt, Saudi Arabia, Switzerland and 19 more places (source, read 2026-09-26). That leaves out 10.2% of the developers GitHub counts, beyond the countries under comprehensive US embargo (Innovation Graph, 2026 Q1). In the vendor’s words: “The following table shows the countries where personal use of the platform not related to business, trade, craft, or professional purposes is not supported”.

What happens to what you send

What you send is not used to train models. In the vendor’s words: “IBM does not use your work to improve IBM models. … The foundation models are hosted in IBM Cloud or AWS; your prompts are not sent to third-party platforms.” (source).
