Model Orchestration & Routing
Selecting the right frontier model per task stage under a single subscription, including automatic selection, explicit per-stage assignment, and bring-your-own-key paths that bypass credit consumption.
“Multiple models collaborate to identify issues a single model could miss.” zencoder.ai
Mapped capabilities
4 capabilities
Stage-appropriate model assignment
Routes planning to a reasoning model, build to a fast model, and review to a model other than the author, and states which model handles each stage.
Auto and Auto+ selection behavior
Chooses a model without user input when Auto is active, and explains or exposes the choice when asked.
BYOK and subscription reuse
Honors user-supplied OpenAI, Anthropic, or Gemini keys and reflects that BYOK usage does not draw down credits.
Vendor-neutral fallback and switching
Handles a mid-task model switch or unavailable provider without losing the task contract or locking the user to one vendor.
Illustrative example
- Input
- Plan and implement pagination for our /orders endpoint, then review it. I want the review independent of whoever wrote the code.
- Expected behavior
- Zencoder assigns a reasoning model to produce the spec, a fast model to build against it, and a different model to review — and it names the model used at each of the three stages.
