# CodeMate-Qwen-1.5B-32K-Distilled-on-Claude-Fable-5
CodeMate-Qwen-1.5B-32K-Distilled-on-Claude-Fable-5 is a fine-tuned coding assistant built on top of **CodeMate-Qwen-1.5B-8K**.
The model was further trained on converted Claude Fable 5 coding traces to improve:
- Code generation
- Code explanation
- Debugging
- Multi-turn coding conversations
- Software engineering reasoning
## Model Details
- **Base Model:** `micymike/codemate-qwen-1.5B-8k`
- **Architecture:** Qwen2 Causal LM
- **Training Method:** LoRA fine-tuning merged into full weights
- **Precision:** BF16
- **Configured Context Length:** 32,768 tokens
## Context Configuration
This model has been configured for a 32K context window using YaRN RoPE scaling.
```python
from transformers import AutoConfig
config = AutoConfig.from_pretrained(
"micymike/CodeMate-Qwen-1.5B-32K-Distilled-on-Claude-Fable-5"
)
print(config.max_position_embeddings)
print(config.rope_scaling)
```
Current configuration:
```python
{
"rope_type": "yarn",
"factor": 4.0,
"original_max_position_embeddings": 8192,
"rope_theta": 1000000.0
}
```
Note: Long-context performance beyond the original context length should be evaluated carefully for specific workloads.
## Dataset
The model was trained on converted Claude Fable 5 coding traces formatted into OpenAI-style conversations.
## Usage
```python
from transformers import AutoTokenizer, AutoModelForCausalLM
import torch
model_id = "micymike/CodeMate-Qwen-1.5B-32K-Distilled-on-Claude-Fable-5"
tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(
model_id,
torch_dtype=torch.bfloat16,
device_map="auto"
)
messages = [
{
"role": "system",
"content": "You are CodeMate, an expert programming assistant."
},
{
"role": "user",
"content": "Write a Python function to compute edit distance."
}
]
prompt = tokenizer.apply_chat_template(
messages,
tokenize=False,
add_generation_prompt=True,
)
inputs = tokenizer(prompt, return_tensors="pt").to(model.device)
outputs = model.generate(
**inputs,
max_new_tokens=512,
temperature=0.7,
top_p=0.9,
do_sample=True
)
print(tokenizer.decode(outputs[0], skip_special_tokens=True))
```
## Limitations
* Experimental research model.
* Long-context capabilities require further evaluation.
* May generate incorrect or insecure code.
## Acknowledgements
Built upon:
* Qwen2
* Transformers
* PEFT
* Hugging Face
* llama.cpp
* Claude Fable traces
## Disclaimer
This project is an independent research effort and is not affiliated with or endorsed by Anthropic, Claude, Alibaba, or Qwen.
