Model ID
Use with the Workers AI binding, the AI Gateway REST API, or the Unified API.
Calling the provider directly? Use the provider's model name instead, including with provider-native endpoints or the provider's own SDK. For example, Anthropic's name for anthropic/claude-opus-4.8 is claude-opus-4-8.
- Third-party
The fastest Krea 2 model, built for low-cost iteration on expressive illustrations, style-driven concepts, and rapid visual exploration. Keeps the Krea 2 style system and expressive visual range but uses a distilled sampling schedule so you can move through ideas much faster. Especially useful for expressive illustration, graphic styles, typography experiments, and quick campaign or concept directions.
