# SecureCoder 30B Pro v1 — LoRA adapter (deprecated, known defect)
> [!WARNING]
> **Deprecated. This adapter produces code that does not parse** — it emits the literal
> two-character sequence `\n` instead of real newlines, so Python blocks fail
> `ast.parse` at line 1.
>
> Measured on identical prompts with the same harness:
>
> | Model | literal `\n` in replies | valid Python |
> |---|---:|---:|
> | `unsloth/Qwen3-Coder-30B-A3B-Instruct` (base) | — | **93.3%** |
> | this adapter | 14/15 | ~6.7% |
>
> **Root cause:** the training mix contains datasets whose message text is stored
> **JSON-escaped** (Trendyol Cybersecurity, Fenrir v2.1, OWASP-sft, Heimdall v1.1,
> CTF-Instruct). 183 of 480 sampled rows were affected.
>
> **Fixed** in [`Taimwe/securecoder-scripts`](https://huggingface.co/Taimwe/securecoder-scripts)
> (`_unescape_if_needed()`, commit `51a4d639`).
>
> The merged weights and GGUF that were built from this adapter — including
> `securecoder-30b-pro-merged` (345 downloads) — were **deleted** because they shipped
> broken output.
## What is here
Only the **LoRA adapter** (53.5 MB), kept for reproducibility. Everything built from it was
removed. For a working code model use the base
[`unsloth/Qwen3-Coder-30B-A3B-Instruct`](https://huggingface.co/unsloth/Qwen3-Coder-30B-A3B-Instruct).
## Adapter config
| | |
|---|---|
| Type | LoRA (`peft 0.21.0`) |
| Rank `r` / alpha | 32 / 32 |
| Target modules | `q_proj`, `k_proj`, `v_proj`, `o_proj` (attention only) |
| Base | `Qwen3MoeForCausalLM` |
