-# RadonSAI-Small - 22M Parameter GPT2-based Russian-English Transformer
-
-## Model Description
-
-RadonSAI-Small is a 22M parameter transformer model based on GPT2 architecture, optimized for Russian-English machine learning applications and development/testing purposes.
-
-### Key Features
-
-- **Architecture**: GPT2-based with optimized parameters
-- **Parameters**: 21,764,608 parameters (22M)
-- **Context**: 512 tokens
-- **Tokenizer**: Optimized for Russian-English
-- **Status**: Ready for inference and fine-tuning
-- **Size**: Compact model for development and testing
-
-### Model Weights
-
-This model contains properly initialized weights:
-
-- **Format**: Safetensors (.safetensors) + PyTorch (.bin)
-- **Dtype**: float32
-- **Initialization**: Random weights
-- **Size**: 86MB (22M parameters)
-- **Status**: Ready for inference and fine-tuning
-
-### Usage
-
-```python
-from transformers import AutoModelForCausalLM, AutoTokenizer
-
-# Load RadonSAI-Small
-model = AutoModelForCausalLM.from_pretrained("MagistrTheOne/RadonSAI-Small")
-tokenizer = AutoTokenizer.from_pretrained("MagistrTheOne/RadonSAI-Small")
-
-# Generate text
-prompt = "Машинное обучение - это"
-inputs = tokenizer(prompt, return_tensors="pt")
-outputs = model.generate(
-    **inputs, 
-    max_length=100, 
-    temperature=0.7,
-    do_sample=True,
-    pad_token_id=tokenizer.eos_token_id
-)
-result = tokenizer.decode(outputs[0], skip_special_tokens=True)
-print(result)
-```

-### Model Architecture
-
+# RadonSAI-Small
+
+## Overview
+RadonSAI-Small is a lightweight variant of the Radon model family, based on the GPT-2 architecture.
+
+## Source Model
+- **Source**: gpt2
+- **Model Class**: GPT2LMHeadModel
+- **Parameters**: 124M (actual size from source)
+- **Architecture**: GPT-2 Small
+
+## Artifacts
+- `model.safetensors` - Model weights in safetensors format (~480MB)
+- `tokenizer.json` - Tokenizer configuration
+- `tokenizer_config.json` - Tokenizer metadata
+- `vocab.json` - Vocabulary file
+- `merges.txt` - BPE merge rules
+- `config.json` - Model configuration (normalized)
+
+## How to Verify
+```bash
+# Run inference test
+python3 tests/test_inference_small.py
 ```
-RadonSAI-Small:
-- Hidden size: 256
-- Layers: 6
-- Attention heads: 8
-- Intermediate size: 1,024
-- Vocabulary: 32,000
-- Context window: 512 tokens
-- Architecture: GPT2LMHeadModel
-```
-
-### Performance
-
-- **Speed**: Fast inference on CPU/GPU
-- **Memory**: 86MB memory usage
-- **Quality**: Development/testing model
-- **Languages**: English + Russian support
-
-### Use Cases
-
-- **Development**: Quick prototyping and testing
-- **Learning**: Educational purposes
-- **Experimentation**: Model architecture research
-- **Resource-constrained**: Low-memory environments

+## Conversion Steps
+1. Download gpt2 from Hugging Face
+2. Convert weights to safetensors format
+3. Save tokenizer files
+4. Normalize config JSON with correct architectures and model_type
+5. Validate with inference test
+
+## Notes
+- This variant uses the original parameter count of the source model (124M)
+- Target label suggests 21M parameters, but actual size is 124M from gpt2
+- To achieve the target 21M parameters, consider:
+  - Knowledge distillation from a larger model
+  - Pruning techniques
+  - Training from scratch with reduced architecture
+
+## File Sizes
+- Total folder size: ~500MB
+- Model weights: ~480MB
+- Tokenizer files: ~20MB
