Simplifying, stabilizing, and scaling continuous-time consistency models
Two sampling steps. That's what OpenAI's new consistency models need to match leading diffusion models.

Why it matters
OpenAI has simplified and scaled continuous-time consistency models to achieve parity with state-of-the-art diffusion models while cutting sampling steps in half. This is a fundamental architectural improvement that could reshape inference efficiency in generative AI.
The key facts
5 to knowContinuous-time consistency models simplified and stabilized
Achieves comparable sample quality to leading diffusion models
Requires only 2 sampling steps (vs. typical 20-50 for diffusion models)
