As recorded at collection: 8 or more free AI model APIs, including NVIDIA NIM

A list of AI model APIs that can be used without separate payment. It introduces NVIDIA NIM, ZAI's GLM-4.7-Flash, OpenRouter, HuggingFace, LiteRouter, Kilo, and OllamaCloud. It also includes the Xiaomi MiMo API shared by a community member from their unused allowance, as well as modeloc, which provides GLM5.2 and deepseek4pro.

Create an account on each service's website, obtain an API key (the authentication string required to use the service), and enter it in the program you want to use. For unlimited use on LiteRouter, select models marked free in the model list; on Kilo, select kilo-auto/free. Find the connection details for the personally shared MiMo and modeloc in the relevant posts.

Most services limit the number of requests you can send simultaneously. ZAI's GLM-4.7-Flash only limits the number of concurrent uses, with unlimited usage. OpenRouter and HuggingFace limit both concurrent use and daily request counts, while OllamaCloud limits weekly usage. NVIDIA NIM is relatively stable, but connections may be slow. MiMo and modeloc use APIs shared by individuals and may be blocked at any time. Access will stop if the provider discontinues the service, so it is best not to rely on them for important work.
