Licensing
Closed source, licensed through your plan
Proprietary agents
Tacsmith's agents, models and training code are closed source. They aren't published or licensed for redistribution, and you use them only through the hosted API.
Commercial use
The Personal plan is for learning and non-commercial projects. Paid plans include a commercial licence to use agent decisions in the titles they cover. Enterprise plans can arrange on-premises deployment under a separate agreement.
Questions
Can I try before paying?
Yes. The Personal plan is free and includes 1,000 API calls a month.
What counts as an API call?
Each request that returns an agent decision, such as a move or an action. Reading analytics and managing profiles is free.
Do I get the new agent types?
As each new agent type becomes available, Studio and Enterprise plans get early access. See In Development for the current status.
Can you build a bespoke agent?
Yes. Enterprise plans can include custom agents and behaviour systems built for your game's mechanics.
