r-1 is currently in preview. API requests use legacy Parse unless they set settings.model to "r-1". New pipelines in Studio use r-1 by default.
At a high level, r-1 delivers agentic-quality parsing through a unified full-page model and supports the full Parse configuration surface except for the settings listed below. Some settings are ignored because r-1 handles the behavior natively, while others are not supported yet. Custom prompts and advanced chart extraction remain available as specialized agentic augmentations.

Enable r-1

Set settings.model to "r-1" on a V3 Parse request. A request that omits settings.model runs on legacy Parse. Set "legacy" to pin legacy Parse explicitly.

V3 configuration compatibility

V2 configurations

r-1 is not available through the V2 API. V2 requests always use legacy Parse. To use r-1, convert your request to the V3 API first. The V2 to V3 converter transforms an existing V2 config, then review the V3 table above before enabling r-1.
Remove unsupported settings before migrating an existing configuration to r-1. Requests containing incompatible settings can fail validation.
