+# slm125MLIVE-base
+
+A 125M-parameter LLaMA-architecture small language model pretrained from scratch
+on a legal + financial corpus. Base model (no instruction tuning).
+
+## Model
+- Architecture: LLaMA (transformers `LlamaForCausalLM`), 12 layers / 768 hidden /
+  12 heads (MHA), SwiGLU, RoPE, RMSNorm, tied embeddings.
+- Params: ~125.8M. Context length: 1024. Vocab: 16,384 (byte-level BPE trained
+  on this corpus).
+
+## Training data (~2.04B tokens, 1 epoch)
+Legal-first mix, cleaned / deduplicated / decontaminated:
+- `HFforLegal/case-law` (US court opinions) — ~40%
+- `PleIAs/SEC` (SEC filings) — ~40%
+- `HuggingFaceFW/fineweb-edu` (educational web) — ~20%
+
+Decontaminated against CaseHOLD / LexGLUE (13-gram overlap removal).
+
+## Results
+- Validation perplexity: **10.44** (full held-out set, 20.56M tokens).
+- Final val loss: 2.346. Trained 3,889 steps at a 524,288-token global batch.
+
+## Usage
+```python
+from transformers import AutoModelForCausalLM, AutoTokenizer
+tok = AutoTokenizer.from_pretrained("sumitguha13/slm125MLIVE-base")
+model = AutoModelForCausalLM.from_pretrained("sumitguha13/slm125MLIVE-base")
+ids = tok("<|bos|>The plaintiff shall bear the burden of", return_tensors="pt").input_ids
+print(tok.decode(model.generate(ids, max_new_tokens=60)[0], skip_special_tokens=True))
+```
+
+## Limitations
+Base model: generates fluent, domain-appropriate text but invents facts and does
+not follow instructions. Not for production or legal/financial advice.
