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
More than 2x the size of Medium, with softer post-training. Outputs are rawer, more textured, and more flexible — at its best, Large produces results Medium can't match. Strongest on photorealism, raw looks (motion blur, grain, low dynamic range), and expressive and artistic styles.
