Introduction of csm-1b-GGUF

Model Details of csm-1b-GGUF

CSM-1B — GGUF (ggml-quantised)

GGUF / ggml conversion of sesame/csm-1b (Conversational Speech Model) for use with CrispStrobe/CrispASR .

CSM-1B is a TTS model that generates speech from text using a two-stage transformer architecture:

  • Backbone (Llama-3.2 1B, 16 layers): generates first-codebook Mimi tokens autoregressively
  • Depth decoder (Llama-3.2 100M, 4 layers): fills remaining 31 codebooks per frame
  • Mimi codec (Kyutai, 8-layer transformer + SEANet): converts 32-codebook RVQ tokens to 24 kHz PCM

Files
File Quant Size Notes
csm-1b-f16.gguf F16 3.4 GB Full precision — reference quality
csm-1b-q8_0.gguf Q8_0 1.9 GB Recommended — identical ASR roundtrip
csm-1b-q4_k.gguf Q4_K 1.1 GB Smallest — minor quality loss
Quick start
# 1. Build CrispASR
git clone https://github.com/CrispStrobe/CrispASR
cd CrispASR
cmake -B build -DCMAKE_BUILD_TYPE=Release
cmake --build build -j --target crispasr-cli

# 2. Download model
huggingface-cli download cstr/csm-1b-GGUF csm-1b-q8_0.gguf --local-dir .

./build/bin/crispasr --backend csm -m csm-1b-q8_0.gguf \
    --tts "Hello, how are you today?" \
    --tts-output hello.wav --seed 42

Or with auto-download:

./build/bin/crispasr -m csm --auto-download \
    --tts "The quick brown fox jumps over the lazy dog." \
    --tts-output fox.wav
