gemma-4-E4B — Opus Reasoning + Claude Code LoRA
🧠 Opus Reasoning + Claude Code LoRA
LoRA adapters trained on Claude Opus 4.6 reasoning traces and Claude Code tool-use patterns — applied on top of deadbydawn101/gemma-4-E4B-mlx-4bit to give Gemma 4 a reasoning-heavy, structured assistant style.
What this means: these adapters teach the model to think before answering — using
<think>tags for chain-of-thought, multi-step reasoning, and tool-invocation patterns extracted from real Claude Code sessions.
What's in this LoRA
| Source | Examples | Description |
|---|---|---|
| Crownelius/Opus-4.6-Reasoning-2100x-formatted | 2,054 | Claude Opus 4.6 reasoning traces formatted with <think> tags |
| Claude Code tool-use patterns | 140 files | Real Claude Code agentic patterns — file read/write, bash, search loops |
| Total | 2,163 | SFT dataset: assistant completions only (--train-on-completions) |
Training on completions only means the model learns the response style without memorizing specific facts — it generalizes to new prompts.

Training Curve
Loss collapsed fast — the reasoning patterns absorbed cleanly:
Iter 10 → 2.277
Iter 20 → 0.097 ← rapid style acquisition
Iter 50 → 0.00063
Iter 100 → 0.0000398
Iter 200 → 0.0000067 (checkpoint saved)
Iter 1000 → ~3.5e-7 (final)
Quickstart (MLX)
Install base model + adapters
pip install mlx-lm
from mlx_lm import load, generate
# Load base model with LoRA adapters
model, tokenizer = load(
"deadbydawn101/gemma-4-E4B-mlx-4bit",
adapter_path="deadbydawn101/gemma-4-E4B-opus-reasoning-claude-code-lora",
)
messages = [{"role": "user", "content": "Solve this step by step: A train leaves Chicago at 60mph..."}]
prompt = tokenizer.apply_chat_template(messages, add_generation_prompt=True, tokenize=False)
response = generate(model, tokenizer, prompt=prompt, max_tokens=1024, verbose=True)
CLI
mlx_lm.generate \
--model deadbydawn101/gemma-4-E4B-mlx-4bit \
--adapter-path deadbydawn101/gemma-4-E4B-opus-reasoning-claude-code-lora \
--prompt "Write a Python function to find prime numbers and explain your reasoning." \
--max-tokens 1024
Intended Use
Best for prompts where you want the model to:
- Think step by step before responding
- Handle multi-step problems (math, logic, code debugging)
- Follow agentic tool-use patterns (read → reason → act → verify)
- Produce well-structured, deliberate completions
Not ideal for:
- Short creative tasks (adds reasoning overhead)
- Casual chitchat
