Qwen2.5-Coder-7B KernelBook SFT (equal tokens)

Supervised Fine-Tuning (SFT) checkpoint of Qwen/Qwen2.5-Coder-7B-Instruct, post-trained on the KernelBook Triton kernel dataset.

This repo is the equal-exposure SFT checkpoint (checkpoint-350, ~1.06 epochs) selected to match SDFT's one-epoch training for fair comparison.

Method

This model was trained with SFT using TRL's SFTTrainer: standard next-token prediction on chat-formatted prompt → Triton completion pairs, with completion-only loss (prompt tokens masked). Training used DeepSpeed ZeRO-3 and bf16 on Modal.

Dataset

• KernelBook — PyTorch module prompts paired with reference Triton kernels
• Deduplicated, filtered to completions ≤4096 tokens, repo-stratified 80/10/10 split
• Stopped at checkpoint-350 (~1.06 epochs) for parity with the SDFT run

Intended use

Generate Triton GPU kernels from PyTorch-style module descriptions. Best for KernelBook-style conversion prompts; not evaluated as a general-purpose chat or reasoning model.

Quick start

from transformers import AutoModelForCausalLM, AutoTokenizer

model_id = "aadityabuilds/qwen2-5-coder-7b-kernelbook-sft-equal-tokens"
tokenizer = AutoTokenizer.from_pretrained(model_id, trust_remote_code=True)
model = AutoModelForCausalLM.from_pretrained(
    model_id, torch_dtype="auto", device_map="auto", trust_remote_code=True
)

messages = [
    {
        "role": "user",
        "content": "Convert the following PyTorch code to an equivalent Triton kernel...",
    }
]
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=1200, do_sample=False)
print(tokenizer.decode(outputs[0][inputs["input_ids"].shape[1] :], skip_special_tokens=True))

Training summary

Setting	Value
Base model	Qwen2.5-Coder-7B-Instruct
Method	SFT (TRL SFTTrainer, completion-only NLL)
Checkpoint	checkpoint-350 (~1.06 epochs)
Hardware	4× H100 (Modal)

Limitations

Specialized for KernelBook Triton codegen. May show reduced performance on general coding, math, and knowledge benchmarks compared to the base instruct model.
