About this integration

Connect Stack Ai to Definable to route to the best model per task, mix providers in one workflow, fall back on rate-limits. Personas call Stack Ai's 22 tools directly from chat or scheduled flows. Add it to your persona's available models and route requests to it where it fits best.

Connect Stack Ai to Definable and it becomes a set of typed tools your agents plan with — triggered by events, run on schedules, or invoked mid-conversation. Every write is checked by the verifier before it lands.

What teams actually run.

Three patterns teams run with Stack Ai on day one. Each one is a plain-English prompt — no canvas, no glue code — and you can remix them into anything.

Multi-provider routing

│ Persona decides which model fits

│ Calls this provider when its strengths apply

└ Falls back to alternatives on rate-limits

Specialised pipeline

│ Use this provider for one stage

│ Pipe to a different model for the next

└ Combine outputs in the response

Anything Stack Ai exposes through its API. Common artificial intelligence workflows on Definable include route to the best model per task, mix providers in one workflow, fall back on rate-limits. Personas can call any of the 22 Stack Ai tools directly, then chain the result into another integration without you writing code.

02 How does Stack Ai authentication work?

Stack Ai uses API_KEY on Definable. You connect once from the integrations page, scoped to the permissions you choose, and from then on any persona that has the integration enabled can act on your behalf. Tokens are encrypted at rest and rotated automatically.
