Most tools make you choose a provider, paste an API key, and add a card before you can find out whether they help. We cut all of that. Install Adsum IoT Coder and it just works. Inference runs on a managed model hosted by Adsum Networks, so you can point the agent at your own firmware in the first minute, not the first hour. It is a real working tier, generous enough to scaffold a project and run a full debug loop, not a locked demo.
No key, no account, no card. The free tier is on by default.

Free tier vs your own key

​
Switching to your own key

When you want a specific model or heavier usage, drop in a key for the GLM Coding Plan, Claude, DeepSeek, or any OpenAI- or Anthropic-compatible endpoint, and the switch is instant: the task you are in keeps running, no restart. The free tier is token-metered. A “tokens left” indicator decrements with real usage and the balance is tracked and enforced by Adsum. When you reach the limit, a one-click prompt moves you onto your own key and the same task picks up exactly where it left off.
