Libraries

How to use sriksven/CodeLens-7B with Transformers:

# Use a pipeline as a high-level helper
from transformers import pipeline

]
pipe(messages)

# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("sriksven/CodeLens-7B")
model = AutoModelForCausalLM.from_pretrained("sriksven/CodeLens-7B")
messages = [

	# CodeLens-7B

	A fine-tuned Qwen2.5-7B-Instruct model specialized for code review, bug detection, and programming assistance. It analyzes code snippets, identifies issues, suggests improvements, and writes clean solutions across multiple programming languages.

	## Key Details

	\| \| \|
	\|---\|---\|
	\| Base model \| Qwen/Qwen2.5-7B-Instruct \|
	\| Method \| QLoRA (4-bit NF4, rank 16, alpha 16) \|
	\| Library \| Unsloth + TRL SFTTrainer \|
	\| Dataset \| sahil2801/CodeAlpaca-20k (10K examples) \|
	\| Hardware \| NVIDIA RTX A5000 (24GB VRAM) on RunPod \|
	\| Training time \| ~2.65 hours (500 steps) \|
	\| Final loss \| 0.450 \|
	\| Parameters trained \| 40.4M of 7.66B (0.53%) \|
	\| Format \| ChatML \|
	\| Output \| Merged 16-bit safetensors \|

	## Dataset

	Trained on 10,000 examples from [sahil2801/CodeAlpaca-20k](https://huggingface.co/datasets/sahil2801/CodeAlpaca-20k), a code instruction-following dataset covering code generation, debugging, explanation, and review tasks across Python, JavaScript, Java, C, SQL, and more.

	## Usage

	### Transformers

	```python
	from transformers import AutoModelForCausalLM, AutoTokenizer

	model = AutoModelForCausalLM.from_pretrained("sriksven/CodeLens-7B")
	tokenizer = AutoTokenizer.from_pretrained("sriksven/CodeLens-7B")

	messages = [
	{
	"role": "system",
	"content": "You are an expert code reviewer and programmer. Analyze code, find bugs, suggest improvements, and write clean efficient solutions.",
	},
	{
	"role": "user",
	"content": "Review this Python function for bugs and improvements:\n\ndef find_duplicates(lst):\n seen = []\n dupes = []\n for i in lst:\n if i in seen:\n dupes.append(i)\n seen.append(i)\n return dupes",
	},
	]

	inputs = tokenizer.apply_chat_template(messages, return_tensors="pt", add_generation_prompt=True)
	outputs = model.generate(inputs, max_new_tokens=512)
	print(tokenizer.decode(outputs[0], skip_special_tokens=True))
	```

	### Unsloth (faster inference)

	```python
	from unsloth import FastLanguageModel

	model, tokenizer = FastLanguageModel.from_pretrained(
	model_name="sriksven/CodeLens-7B",
	max_seq_length=2048,
	load_in_4bit=True,
	)
	FastLanguageModel.for_inference(model)
	```

	## Capabilities

	- Code review — analyze code for bugs, anti-patterns, and style issues
	- Bug detection — identify logical errors, off-by-one mistakes, edge cases
	- Code generation — write functions, classes, and scripts from descriptions
	- Code explanation — explain what a piece of code does step by step
	- Refactoring suggestions — propose cleaner, more efficient alternatives
	- Multi-language — Python, JavaScript, Java, C/C++, SQL, HTML/CSS, and more

	## Intended Use

	- Local code review assistant
	- Programming tutoring and education
	- Code quality tooling in CI/CD pipelines
	- Prototyping developer tools with local LLMs

	## Limitations

	- Trained on instruction-following code data, not real code review conversations from PRs
	- May not catch security vulnerabilities that require deep context
	- Code suggestions should be tested before use in production
	- Best with shorter code snippets (functions/classes) rather than full files
	- No execution or testing capability — suggestions are pattern-based

	## Training Metrics

	Loss decreased steadily from 2.17 to 0.27 over 500 steps (~13 epochs), indicating strong learning on the code instruction data.

	\| Step \| Loss \| Epoch \|
	\|---\|---\|---\|
	\| 10 \| 2.168 \| 0.26 \|
	\| 100 \| 0.503 \| 2.05 \|
	\| 250 \| 0.430 \| 6.41 \|
	\| 400 \| 0.310 \| 10.26 \|
	\| 500 \| 0.278 \| 12.83 \|

	## Training Infrastructure

	\| \| \|
	\|---\|---\|
	\| GPU \| NVIDIA RTX A5000 24GB \|
	\| Cloud \| RunPod ($0.27/hr) \|
	\| Framework \| Unsloth 2026.5.2 + TRL + Transformers 5.5.0 \|
	\| Precision \| BF16 training, 4-bit NF4 base quantization \|
	\| Optimizer \| AdamW 8-bit \|
	\| Learning rate \| 2e-4, linear decay \|
	\| Batch size \| 16 effective (4 per device × 4 accumulation) \|
	\| Packing \| Enabled \|
