gslm-scaling-309m-4p9b

Model-only FP32 weights for a final-budget scaling-curve endpoint from Scaling Properties of Speech Language Models (EMNLP 2024). This checkpoint has 308,845,568 parameters and saw exactly 4,933,530,000 tokens at 516,600 tokens per update.

model = TransformerLM.from_pretrained("tiagoCuervo/gslm-scaling-309m-4p9b", device="cuda")
prompt = torch.tensor([[12, 91, 204]], device="cuda")
units = model.generate(prompt, max_new_tokens=200, temperature=0.8, top_k=50)

Evaluation scores are 58.61% sBLIMP phenomenon macro accuracy, 55.80% sBLIMP voice-pair accuracy, 54.94% sStoryCloze, and 72.47% tStoryCloze.

The model predicts consecutive-run-collapsed 25 Hz layer-11 mHuBERT K-means units (K=500; EOS=500; PAD=501). A vocoder is not bundled.

Speech-tokenizer and vocoder artifacts are credited in the SLM third-party notices. See provenance.json for exact hashes and evaluation metadata.
