Each message you send to TagoAI counts as one request. This limit defines the maximum number of requests a profile can make during a one-month period when using the TagoIO default AI provider. Unused requests in a billing cycle do not carry over to the next cycle.
When a profile is configured with its own AI provider under Profile Settings → Services → AI Provider, TagoAI requests go through your provider account and are billed directly by that provider. The TagoIO monthly limits above do not apply in that case.
See Using your own AI provider for setup details.
