Hi, I've been using Vapi recently and from my perspective, Assistants, Squads, and Workflows feel overlapping. - With Squads, the forced transfer between agents often breaks the natural conversation flow. - With Workflows, the reliance on strict if-statements feels like a rigid decision tree — not well-suited for live calls where topics can shift dynamically. In practice, the agent can’t “jump” across nodes or reuse prompt training from other branches of the tree, which limits flexibility. Question: Could you explain the intended design philosophy behind each of these (Assistant, Squad, Workflow), how they’re meant to complement each other, and which is the best foundation to invest in long-term? Are there roadmap plans to make them work together more seamlessly (e.g. cross-node learning, smoother transitions) or is there one feature with heavier development or optimisation planned? @Vapi

Hi A.G | Ant, When considering the use of Assistants, Squads, and Workflows in Vapi, it's helpful to understand each tool's ideal use case to address your concerns about natural conversation flow and the flexibility of interactions: - Assistants are best for single-topic, simple interactions where the conversation flow doesn't require complex branching or involving multiple tools. - Squads allow for breaking complex conversations into specialized parts by transferring between multiple Assistants. This setup is useful for maintaining conversation context across assistants handling distinct tasks but may disrupt flow if transfers feel abrupt. It's crucial to define clear triggers for these transfers to maintain a smooth experience. - Workflows are structured to handle intricate, branching logic through nodes and edges, excellent for scenarios with numerous interaction paths but can indeed feel rigid in dynamic settings. While they lack the ability to "jump" nodes dynamically, this determinism can prevent unintended conversation paths. But please note workflows is under development and the team is working on it.

Note that you essentially use Assistants (persitent or transient) in Squads. So all of your prompts, tool calls, voice configs can be setup for assistants and then leverage Squads merely for orchestration. If you use the same voice across Assistants and configure a silent transfer, you can have a multi-assistant setup that sounds (to the caller) like they're speaking to a single person. Workflows are pretty much deprecated at this point.
