Diffusion Text Generation

This directory contains implementations for Diffusion LLMs (DLLMs)

More Info:

• https://github.com/ggml-org/llama.cpp/pull/14644
• https://github.com/ggml-org/llama.cpp/pull/14771

Parameters

The diffusion CLI supports various parameters to control the generation process:

Core Diffusion Parameters

• --diffusion-steps: Number of diffusion steps (default: 256)
• --diffusion-algorithm: Algorithm for token selection
  • 0: DIFFUSION_ALGORITHM_ORIGIN - Token will be generated in a purely random order from https://arxiv.org/abs/2107.03006.
  • 1: DIFFUSION_ALGORITHM_ENTROPY_BASED - Entropy-based selection
  • 2: DIFFUSION_ALGORITHM_MARGIN_BASED - Margin-based selection
  • 3: DIFFUSION_ALGORITHM_RANDOM - Random selection
  • 4: DIFFUSION_ALGORITHM_CONFIDENCE_BASED - Confidence-based selection (default)
  • More documentation here https://github.com/DreamLM/Dream
• --diffusion-visual: Enable live visualization during generation

Scheduling Parameters

Choose one of the following scheduling methods:

Timestep-based scheduling:

• --diffusion-eps: Epsilon value for timestep scheduling (e.g., 0.001)

Block-based scheduling:

• --diffusion-block-length: Block size for block-based scheduling (e.g., 32)

Sampling Parameters

• --temp: Temperature for sampling (0.0 = greedy/deterministic, higher = more random)
• --top-k: Top-k filtering for sampling
• --top-p: Top-p (nucleus) filtering for sampling
• --seed: Random seed for reproducibility

Model Parameters

• -m: Path to the GGUF model file
• -p: Input prompt text
• -ub: Maximum sequence length (ubatch size)
• -c: Context size
• -b: Batch size
