gslm-scaling-823m-26b

Model-only FP32 weights for a complete endpoint from Scaling Properties of Speech Language Models (EMNLP 2024). The model predicts consecutive-run-collapsed, 25 Hz layer-11 mHuBERT K-means units without waveform normalization (K=500; EOS=500; PAD=501). A vocoder is not bundled.

Speech-tokenizer and vocoder artifacts are credited in the SLM third-party notices.
