Frequently asked questions
What are Syntasy tokens?
They are the shared balance used to pay for models in Syntasy. Token pack prices are available on the pricing page. View token packs
Why can the final cost differ from the base rate?
A per-second tariff is multiplied by duration, an image tariff by output count, and a character tariff by text length. Check the estimate on the website or use syntasy_estimate_generation via MCP for your chosen settings.
Can I use this text model via MCP?
This model is available in the Syntasy Text workspace. The current MCP integration provides media generation tools; it does not expose this text model as a chat API.
