CLARA is an advanced generative diffusion model developed by Anthropic to produce high-fidelity synthetic images:

Anthropic claims CLARA sets a new state-of-the-art in image generation quality for adversarial diffusion models. They have not yet released the architecture details or made CLARA publicly available unlike other models like DALL-E. CLARA demonstrates the capabilities of adversarial training and LMS sampling to achieve cutting-edge sample fidelity.

In summary, CLARA is an advanced generative model from Anthropic capable of megapixel image generation with photorealistic quality using adversarial diffusion training and efficient sampling.
