+# reallexi/lexi-rm-agent
+
+A standalone model of 495M parameters, derived from [`Qwen/Qwen2.5-0.5B-Instruct`](https://huggingface.co/Qwen/Qwen2.5-0.5B-Instruct).
+
+The adapter has been merged into the base weights, so no PEFT adapter is needed at runtime.
+
+
+## Size and requirements
+
+| | |
+|---|---|
+| Parameters | 495,114,112 (495M) |
+| Weights on disk | 953 MB |
+| Trained context length | 512 tokens |
+| Base model | `Qwen/Qwen2.5-0.5B-Instruct` |
+
+
+Approximate memory to hold the weights. Add context and runtime overhead on top.
+
+| Precision | Weights |
+|---|---|
+| FP16 / BF16 | 944 MB |
+| 8-bit (Q8_0) | 472 MB |
+| 4-bit (Q4_K_M) | 260 MB |
+
+
+## Training
+
+| | |
+|---|---|
+| Strategy | slm |
+| Adapter | Auto LoRA |
+| LoRA rank / alpha | 8 / 16 |
+| Dataset | `bitext/Bitext-customer-support-llm-chatbot-training-dataset` |
+| Samples learned | 100,000 (through phase 382 of 382) |
+| Training steps | 1,250 |
+| Epochs | 5 |
+
+
+## Usage
+
+```python
+from transformers import AutoModelForCausalLM, AutoTokenizer
+
+model = AutoModelForCausalLM.from_pretrained("reallexi/lexi-rm-agent")
+tokenizer = AutoTokenizer.from_pretrained("reallexi/lexi-rm-agent")
+```
