Free tier: no key, no account, no card - Adsum IoT Coder

Most tools ask you to choose a provider, paste a key and add a card before you learn whether they help. Adsum does not. Install it and it works, on a managed model hosted by Adsum Networks. It is a real working tier, enough for a full debug loop, not a locked demo.

On by default, with no key, no account and no card. Cellular, satellite NB-NTN, nRF54 edge AI and the LEW840x gateway firmware need a free account. Nothing else does.

Free tier strip: inference on Adsum Networks, tokens remaining, Add key — On screen before the first inference: who pays, the balance, and the way to your own key.
