gemma-coder-dev

Coding-focused fine-tune of google/gemma-4-26B-A4B-it (Gemma 4 26B A4B, an MoE with ~4B active params), produced automatically by the weekly retrain pipeline in remote-agent-dev-platform. Last updated: 2026-06-23 09:46 UTC · run mode: full · promoted: False.

Model description

QLoRA fine-tune of google/gemma-4-26B-A4B-it specialized for coding assistance. It is the default agent model for the remote-agent-dev-platform (served via vLLM on Modal).

Intended uses & limitations

  • Intended: code generation and assistance in Python, JavaScript/React, Go, Java, and Swift, inside a sandboxed agent that runs/tests the output.
  • Not intended: safety-critical use, or running generated code unreviewed.
  • Limitations: a small, free-tier-trained model — it can produce incorrect or insecure code. Always review and test. Quality tracks the training data, which is still being built out.

Training data

Training procedure

  • Method: QLoRA (Unsloth), 4-bit base, LoRA r=8 / alpha=16 on attention + MoE experts, lr 2e-4, max seq len 512, optimizer adamw_8bit.
  • Progress: cycle 1 — 599 / 4000 steps (trained in weekly ~8h chunks on Kaggle's free 2×T4, resuming each week; training is continuous — a finished cycle rolls into the next).

Evaluation

Sandboxed multi-language pass@1 harness (finetune/evaluate.py): the model completes functions that are then compiled/run against unit tests. Languages whose toolchain is unavailable are skipped.

Overall pass@1: 39.13% over 23 executed problems (4 skipped). Promotion threshold: 46%.

language passed / run pass@1
go 1/4 25.00%
java 0/4 0.00%
javascript 0/7 0.00%
python 8/8 100.00%
swift 0/0 skipped (no toolchain)

How to use

from transformers import AutoModelForCausalLM, AutoTokenizer
tok = AutoTokenizer.from_pretrained("Monibee-Fudgekins/gemma-coder-dev")
model = AutoModelForCausalLM.from_pretrained("Monibee-Fudgekins/gemma-coder-dev", device_map="auto")
msgs = [{"role": "user", "content": "Write a Python function that reverses a string."}]
ids = tok.apply_chat_template(msgs, add_generation_prompt=True, return_tensors="pt").to(model.device)
print(tok.decode(model.generate(ids, max_new_tokens=256)[0]))
