What is the Latent Consistency Model

The latent Consistency Model (LCM) is a type of distilled diffusion model. With LCM, you can generate high-fidelity images much faster than standard diffusion models in a very short inference time of 1 second to generate 10 images.

• It's trained to predict the output of diffusion models based on their early iteration stages, instead of running the full diffusion process from start to finish. This allows extremely fast generation.
• In tests, LCM has produced images comparable in quality to standard diffusion models, but in as little as 4 steps instead of hundreds. This represents a huge speedup.
• It works by learning the behavior of diffusion models during their early iterations. It then uses this knowledge to consistently predict the final output without needing to run the full diffusion steps.
• This demonstrates how model distillation techniques can accelerate diffusion-based generation when applied effectively.
• LCM was developed by researcher Simian Luo and provides a proof-of-concept for balancing speed and quality in AI image generation.
• Ongoing work aims to enhance LCM further, such as adding negative prompting for even greater control over image properties.

How can the Latent Consistency Model influence future image generation

Where other models may need dozens of steps to generate a comparable result, LCM can achieve this in just 4 steps, taking 1 second to generate 10 images!

This level of speed without sacrificing quality is almost unbelievable. The LCM demonstrates how powerful distillation techniques can be for accelerating AI generation when applied effectively. It's revolutionizing how we think about the relationship between speed and quality for diffusion models.

Step-by-Step Guide for Using the API

Please set the Content-Type header to application/json in your HTTP request to indicate that you are sending JSON data. Currently, only JSON format is supported.

Request:

curl --location --request POST 'https://api.novita.ai/v3/lcm-txt2img' \
--header 'Authorization: Bearer {{key}}' \
--header 'Content-Type: application/json' \
--data-raw '{
   "prompt": "Glowing jellyfish floating through a foggy forest at twilight",
   "height": 512,
   "width": 512,
   "image_num": 2,
   "steps": 8,
   "guidance_scale": 7.5
}'

HTTP status codes in the 2xx range indicate that the request has been successfully accepted, code 400 means requst params error, while status codes in the 5xx range indicate internal server errors.

Response:

{
    "images": [
        {
            "image_file": "{{Base64 encoded image}}",
            "image_type": "jpeg"
        },
        {
            "image_file": "{{Base64 encoded image}}",
            "image_type": "jpeg"
        },
    ]
}

Conclusion

In conclusion, the Latent Consistency Model is a distilled diffusion model trained to generate high-fidelity images exceptionally fast through consistency with standard diffusion model behavior during early iterations. It represents an exciting approach to rapid, high-quality AI image generation.
