+# CRCA 1.5B Full Finetune
+
+## Overview
+CR-CA (Causal Reasoning and Counterfactual Analysis) is a reasoning-focused stack
+that targets structured causal analysis, counterfactuals, and multi-step reasoning.
+This 1.5B model is a CR-CA reasoning-optimized causal language model based on the
+Qwen2 architecture (`Qwen2ForCausalLM`).
+
+## Model Details
+- **Model type:** `qwen2`
+- **Architecture:** `Qwen2ForCausalLM`
+- **Hidden size:** `1536`
+- **Layers:** `28`
+- **Attention heads:** `12` (KV heads: `2`)
+- **Max position embeddings:** `32768`
+- **Vocab size:** `151936`
+- **Dtype:** `float16`
+
+## Training Summary
+This model was produced via full finetuning for CR-CA reasoning. Training metadata
+is stored in `training_args.bin`.
+
+Key training parameters:
+- **Per-device batch size:** 8
+- **Gradient accumulation:** 16
+- **Epochs:** 2
+- **Learning rate:** 5e-4
+- **Precision:** FP16
+- **DeepSpeed config:** `training/deepspeed_zero2_1_5b.json`
+- **Scheduler:** cosine
+- **Warmup steps:** 100
+- **Save steps:** 200
+
+## Training Data
+The training data uses a prompt/response JSONL format:
+
+```
+{"prompt": "...", "response": "..."}
+```
+
+The dataset includes public reasoning data (e.g., GSM8K-style math word problems).
+This is used to strengthen multi-step reasoning, structured derivations, and final
+answer formatting.
+
+## Intended Use
+For causal reasoning, counterfactual analysis, structured CR-CA reasoning prompts,
+and multi-step reasoning tasks.
+
+## Generation Settings
+Default generation parameters are stored in `generation_config.json`:
+- `do_sample`: `true`
+- `temperature`: `0.7`
+- `top_p`: `0.8`
+- `top_k`: `20`
+- `repetition_penalty`: `1.1`
+
+## Limitations
+- Outputs should be validated for factual correctness.
+- The model may hallucinate causal claims without evidence.
