- # sandeshrajx/qwopus-lora-tests
18
-
19
- LoRA adapters and GGUF exports from an experimental Qwen 3.5 18B REAP-A3B coding fine-tune on Opus-distilled reasoning and coding data.
20
-
21
- ## What This Repo Contains
22
-
23
- This repo is being used to compare a base checkpoint against a lightweight supervised fine-tune focused on coding-style outputs with explicit `<think>...</think>` reasoning scaffolds.
24
-
25
- It contains:
26
-
27
- - A LoRA adapter trained from `Flagstone8878/Qwen3.5-18B-REAP-A3B-Coding`
28
- - Matching tokenizer files required to load the adapter
29
- - GGUF exports for llama.cpp-compatible testing
30
-
31
- ## Training Setup
32
-
33
- - Base model: `Flagstone8878/Qwen3.5-18B-REAP-A3B-Coding`
34
- - Dataset: `nohurry/Opus-4.6-Reasoning-3000x-filtered`
35
- - Run name: `qwen35-18b-reap-a3b-coding-opus-msl8192-e2_0-lr2e4`
36
- - Context length: `8192`
37
- - Epochs: `2.0`
38
- - Learning rate: `0.0002`
39
- - Effective batch size: `24`
40
- - Observed steps: `194`
41
- - Final reported train loss: `0.5748463515768346`
42
-
43
- ## Goal
44
-
45
- The current goal is not to claim a production-quality coding model. This is an iterative testing repo for:
46
-
47
- - checking whether the LoRA improves structure and responsiveness versus the base model
48
- - measuring how well the model handles coding prompts with reasoning traces
49
- - comparing adapter behavior and GGUF behavior across different inference stacks
50
-
51
- ## Prompt Format
52
-
53
- Training examples were rendered in Qwen chat format. Assistant messages were structured like:
54
-
55
- ```text
56
- <think>
57
- ...reasoning...
58
- </think>
59
-
60
- ...final answer...
61
- ```
62
-
63
- Response-only loss masking was applied starting at:
64
-
65
- ```text
66
- <|im_start|>assistant
67
- <think>
68
- ```
69
-
70
- That means the opening `<think>` token itself was used as the masking boundary during training.
71
-
72
- ## Current Quality Notes
73
-
74
- This is an experimental checkpoint. Early prompt testing shows that the LoRA can produce shorter and more coherent outputs than the untouched base model on some coding prompts, but the generated code is still not consistently correct or production-ready.
75
-
76
- Use it for:
77
-
78
- - comparative testing
79
- - prompt behavior inspection
80
- - llama.cpp / GGUF experiments
81
-
82
- Do not assume it is a fully validated coding model.
83
-
84
- ## Loading The LoRA
85
-
86
- Use the adapter with the original base model:
87
-
88
- ```python
89
- from transformers import AutoTokenizer
90
- from peft import AutoPeftModelForCausalLM
91
-
92
- model = AutoPeftModelForCausalLM.from_pretrained("sandeshrajx/qwopus-lora-tests", trust_remote_code=True)
93
- tokenizer = AutoTokenizer.from_pretrained("sandeshrajx/qwopus-lora-tests", trust_remote_code=True, use_fast=False)
94
- ```
95
-
96
- If your runtime expects the original base model separately, load `Flagstone8878/Qwen3.5-18B-REAP-A3B-Coding` and then attach the adapter from this repo.
97
-
98
- ## GGUF Notes
99
 
100
- The GGUF files in this repo are intended for downstream testing in llama.cpp-compatible runtimes. They are provided as convenience artifacts for experimentation and may differ from Transformers / PEFT behavior depending on the backend and quantization format.
 
 
101
 
102
- ## Provenance
103
 
104
- Artifacts were produced from local Modal training and export scripts in the `qwen-opus-finetune` workspace, then uploaded to Hugging Face for external evaluation.
