# Route Complex Execution to GPT-5.5

## Action
For multi-step tasks involving files, code, documents, browser use, or data migration, set [[entity-gpt-5-5|GPT-5.5]] (specifically within [[entity-codex|Codex]]) as the **default routing choice**.

## Why
- Superior execution and context-carrying capabilities (see [[concept-can-it-carry]]).
- Best results on adversarial multi-step tests (see [[claim-gpt-5-5-superiority]]).
- Backed by OpenAI's higher-availability infrastructure (see [[concept-availability-as-quality]]).

## Expected Outcome
Higher completion rates and fewer dropped threads on complex deliverables.

## Caveats
- Pair with [[action-implement-human-validation]] for any production-data path.
- For aesthetic-first work, route to Opus instead — see [[action-route-visual-design]].
- For UIs that need both, use the hybrid in [[action-mockup-to-code]].
