Converts natural language text prompts into images using a two-stage pipeline: text embeddings are first processed through a diffusion prior (1B parameters in v2.1+) that maps text space to CLIP image embeddings, then fed into a latent diffusion U-Net (1.2-1.22B parameters) operating in compressed latent space. Kandinsky 2.0 uses dual text encoders (mCLIP-XLMR 560M + mT5-encoder-small 146M) while v2.1+ uses XLM-Roberta-Large-ViT-L-14 (560M). The diffusion prior acts as a bridge between modalities, enabling more coherent image generation than direct text-to-pixel approaches.
Unique: Implements a two-stage diffusion prior architecture that explicitly maps text embeddings to CLIP image space before pixel generation, enabling stronger semantic alignment than single-stage models. Kandinsky 2.1+ replaces standard VAE with MOVQ encoder/decoder (67M parameters) for better reconstruction quality in latent space.
vs alternatives: Outperforms Stable Diffusion v1.5 on multilingual prompts and achieves comparable quality to DALL-E 2 while remaining fully open-source and locally deployable without API calls.
Transforms existing images by encoding them into latent space via MOVQ encoder, then applying iterative diffusion steps guided by text prompts and a strength parameter (0-1) that controls how much the original image influences the output. The process uses the same diffusion prior and U-Net as text-to-image but initializes the noise schedule at a later timestep based on strength, allowing fine-grained control over preservation vs. modification. Supports both Kandinsky 2.0 (direct U-Net conditioning) and 2.1+ (diffusion prior + U-Net) architectures.
Unique: Uses MOVQ encoder (67M parameters) instead of standard VAE for input image encoding, providing better reconstruction fidelity in latent space. Strength parameter controls noise schedule initialization, enabling smooth interpolation between preservation and regeneration without separate model variants.
vs alternatives: Achieves finer control over image preservation than Stable Diffusion's img2img through explicit diffusion prior conditioning, and supports multilingual prompts natively unlike most open-source alternatives.
Classifier-free guidance (CFG) is implemented by computing both conditional (text-guided) and unconditional predictions, then scaling the difference: output = unconditional + guidance_scale * (conditional - unconditional). Higher guidance scales (10-15) increase semantic alignment with text prompts but reduce image diversity and may introduce artifacts. Lower scales (5-8) produce more diverse but less prompt-aligned images. Guidance scale is a hyperparameter exposed in all generation methods.
Unique: Exposes guidance scale as a simple float parameter that controls the strength of text conditioning without requiring model retraining. Enables smooth interpolation between unconditional and fully-conditional generation.
vs alternatives: Simpler and more intuitive than alternative guidance methods (e.g., attention-based guidance); widely adopted across diffusion models for its effectiveness and ease of use.
MOVQ (Multiscale Orthogonal Vector Quantization) is a 67M parameter encoder-decoder that compresses images into latent space for efficient diffusion processing. Unlike standard VAE, MOVQ uses vector quantization to discretize latent codes, improving reconstruction fidelity and reducing artifacts. Introduced in Kandinsky 2.1 as a replacement for VAE. The encoder downsamples images by 8x; the decoder upsamples latent codes back to pixel space with minimal quality loss.
Unique: Uses multiscale orthogonal vector quantization instead of standard VAE, providing better reconstruction fidelity and fewer artifacts in latent space. Enables high-quality image editing without pixel-level quality loss.
vs alternatives: MOVQ reconstruction quality exceeds standard VAE used in Stable Diffusion v1.5, reducing artifacts in image-to-image and inpainting tasks. Vector quantization provides discrete latent codes that may be more interpretable than continuous VAE latents.
Kandinsky 2.0 uses two text encoders in parallel: mCLIP-XLMR (560M parameters) for multilingual semantic understanding and mT5-encoder-small (146M parameters) for linguistic structure. Both encoders process the same text prompt independently, producing separate embeddings that are concatenated and fed into the U-Net. This dual-encoder approach enables strong multilingual support without requiring separate models per language. Kandinsky 2.1+ replaces this with a single XLM-Roberta-Large-ViT-L-14 encoder (560M).
Unique: Combines mCLIP-XLMR (semantic understanding) and mT5-encoder-small (linguistic structure) in parallel, enabling richer text representation than single-encoder approaches. Dual-encoder design is unique to Kandinsky 2.0.
vs alternatives: Dual-encoder architecture captures both semantic and linguistic information, potentially improving text understanding compared to single-encoder v2.1+. However, v2.1+ achieves comparable quality with lower latency using a unified encoder.
Negative prompts are text descriptions of unwanted content (e.g., 'blurry, low quality, distorted'). During generation, the model computes predictions for both positive and negative prompts, then uses the difference to steer generation away from negative content. Implemented via classifier-free guidance: output = conditional_positive + guidance_scale * (conditional_positive - conditional_negative). Negative prompts are optional but widely used to improve quality by excluding common artifacts.
Unique: Implements negative prompts via classifier-free guidance difference, enabling content exclusion without separate model components. Negative prompts are computed in the same forward pass as positive prompts, adding minimal overhead.
vs alternatives: Simpler and more flexible than hard content filtering; allows fine-grained control over excluded content through natural language. Comparable to negative prompts in Stable Diffusion but with multilingual support.
Fills masked regions of images by encoding the full image into latent space, zeroing out latent features corresponding to masked pixels, then running diffusion with text guidance to reconstruct masked areas while preserving unmasked context. The process uses the diffusion prior (v2.1+) or direct U-Net conditioning (v2.0) to guide generation toward text-aligned completions. Mask can be binary (0/255) or soft (grayscale 0-255) for graduated blending at boundaries.
Unique: Implements inpainting by zeroing latent features in masked regions rather than pixel-space masking, enabling coherent completion that respects both text guidance and unmasked image context. Supports soft masks (grayscale) for smooth boundary blending, reducing visible seams.
vs alternatives: Produces fewer boundary artifacts than Stable Diffusion inpainting due to diffusion prior conditioning, and supports multilingual prompts for non-English inpainting instructions.
Combines multiple images and text prompts by encoding each image into CLIP embeddings via the image encoder (ViT-L/14 in v2.1, ViT-bigG-14 in v2.2), interpolating or averaging embeddings, then using the diffusion prior to map the blended embedding to a coherent image. Supported in Kandinsky 2.1+ only. Allows weighted blending of image concepts (e.g., 0.7*image1 + 0.3*image2) with text guidance to steer the final output toward desired attributes.
Unique: Operates in CLIP embedding space rather than pixel or latent space, enabling semantic blending of image concepts. Uses diffusion prior to map interpolated embeddings back to coherent images, allowing fine-grained control over blend ratios without retraining.
vs alternatives: Provides explicit control over image blending weights and text guidance, unlike simple image averaging or GAN-based morphing, and leverages the diffusion prior for higher-quality outputs than direct embedding interpolation.
