  <dc:title>Stable Diffusion Image Generation</dc:title>
  <dc:title>R package sd2R version 0.1.7</dc:title>
  <dc:description>Provides Stable Diffusion image generation in R using the 'ggmlR'
    tensor library. Supports text-to-image and image-to-image generation with
    multiple model versions (SD 1.x, SD 2.x, 'SDXL', Flux). Implements the
    full inference pipeline including CLIP text encoding, 'UNet' noise removal,
    and 'VAE' encoding/decoding. Unified sd_generate() entry point with
    automatic strategy selection (direct, tiled sampling, high-resolution fix)
    based on output resolution and available 'VRAM'. High-resolution generation
    (2K, 4K+) via tiled 'VAE' decoding, tiled diffusion sampling
    ('MultiDiffusion'), and classic two-pass refinement (text-to-image, then
    upscale with image-to-image). Multi-GPU parallel generation via
    sd_generate_multi_gpu(). Multi-GPU model parallelism via 'device_layout'
    in sd_ctx(): distribute diffusion, text encoders, and 'VAE' across
    separate 'Vulkan' devices. Built-in profiling (sd_profile_start(),
    sd_profile_summary()) for per-stage timing of text encoding, sampling,
    and 'VAE' decode. Supports CPU and 'Vulkan' GPU. No 'Python' or external
    API dependencies required. Cross-platform: Linux, macOS, Windows.</dc:description>
