What you get

Nous Research’s inference portal with a $0 Free plan for :free models, accessible through an OpenAI-compatible API and Hermes Agent

Free models

step-3.7-flash, solar-mini-4

Limits, in the vendor’s words

Free models: Usage allowance: amount not published (period not published) per account

Choose the Free plan and use exact :free IDs; they are zero-priced, while metered routes are outside it. Use a portal key with ordinary API clients; the catalog itself is public. The Free plan publishes no card requirement or numerical rate cap.

Where it is offered

The vendor names no country it keeps the offer from (source, read 2026-09-26).

What happens to what you send

What you send may be used to train or improve models unless you turn that off. In the vendor’s words: “When Privacy Mode is enabled, we will not store your inference payloads and will not use such inference payloads for training, product improvement, or support purposes” (source).

Connect

Try it from your terminal with your key in NOUS_PORTAL_API_KEY — it goes from your machine to the vendor and nowhere else:

curl -s https://inference-api.nousresearch.com/v1/chat/completions \
  -H "Authorization: Bearer $NOUS_PORTAL_API_KEY" \
  -H 'Content-Type: application/json' \
  -d '{"model":"stepfun/step-3.7-flash:free","messages":[{"role":"user","content":"2+2? MAKE NO MISTAKES."}]}'
