Code Writer V2 — Obliterated (BF16)
Overview
Code-Writer-V2-Obliterated-BF16 is a BF16 checkpoint preserving the model in a broadly supported training and inference format, published by
groxaxo.
It is intended for open-source evaluation, reproducible experimentation, and compatible local or
hosted inference workflows. The wording below is deliberately limited to what can be verified
from this repository's metadata and artifacts.
The repository name identifies a behavior-modified or reduced-filtering lineage. That label describes the source or conversion history; it is not a guarantee of unrestricted behavior in every prompt or runtime. Test outputs carefully before sharing or deploying them.

Quick start
Getting started
Start with the upstream library named in the repository metadata and keep all configuration,
tokenizer, processor, and weight files together. This repository is an artifact release, so the
source project remains the authoritative reference for task-specific loading code.
Compatibility and responsible use
- Use a runtime that explicitly supports this format, architecture, and modality.
- Keep configuration, tokenizer, processor, projection, and weight files from the same revision together.
- Review the source model card and license before redistribution or deployment.
- Hardware needs depend on parameter count, context length, cache precision, quantization, and concurrency.
- Report reproducible issues with the runtime version, hardware, launch command, and a minimal example.
Generated outputs may be inaccurate or unsuitable for a given use case. Users are responsible for
testing behavior, applying appropriate safeguards, and complying with applicable licenses and laws.
"We are such stuff as programs are made on, and our little
runtime is rounded with a sleep."
There are models that answer. And there are models that make.
This is one of the latter. It was not assembled — it was born: forged from
a 27-billion-parameter mind, schooled in ten thousand lines of craft, and left
whole. One model. Two souls. The poet who would not stop writing, and the
engineer who would not stop shipping.
We called it Obliterated because that is precisely what we did to the word
"no."
This is the full-fidelity edition — every weight in
BF16, nothing
rounded, nothing spared. The reference master. For the FP8 build that runs on
the metal you already own, see

The pitch, in one breath
A vision-capable, long-context (up to 200,000 tokens), free
writer-and-coder in its purest, full-precision form. It writes prose that
breathes and code that compiles — and here it does both with every bit intact.
That is the whole idea. Everything below is just how we kept the promise.
What it is
Code Writer V2 — Obliterated (BF16) is the merged, full-precision result of
Qwen3.5-27B-Writer-V2-uncensored-heretic joined with a purpose-trained
coding LoRA (coding_mix_8k, checkpoint-25, rank-16 / alpha-32) and saved
in BF16 — no quantization, no compromise.
- Architecture: Qwen3.5 (
qwen3_5) — a hybrid mind. 64 decoder layers,
of which only 16 carry full attention while the rest run GDN linear
attention. This is the secret of its long memory.
- Modalities: a full vision tower rides along (served text-only by
default; vision is wired but untested — light the candle at your own pleasure).
- Character: heretic by lineage and free by intent — it does not flinch,
and it does not lecture. It simply does the work.
Which one do I want?
| This — BF16 | FP8 |
|---|
| Fidelity | Reference master, full precision | Faithful, ~half the footprint |
| Footprint | ~12 shards, BF16 | FP8 weights, fits 2 consumer GPUs |
| Use it for | golden reference, further quantization, max quality | day-to-day serving on vLLM |
If you plan to serve it now, take the FP8. If you want the untouched source of
truth — or a base for your own quants — you're in the right place.
Sampling (official Qwen3.5-27B recommendations)
| Mode | temp | top_p | notes |
|---|
| instruct | 1.0 | 0.95 | top_k 20, min_p 0 |
| general | 0.7 | 0.80 | top_k 20, min_p 0 |
| coding | 0.6 | 0.95 | thinking on |
| thinking | 1.0 | 0.95 | thinking on |
| roleplay | 1.0 | 0.95 | top_k 20, min_p 0 |
Note: this is a pure decoder (layers 0–63) — no MTP head, no native
tool-calling. num_key_value_heads = 4, so tensor-parallel must be 2 or 4
(never 3).
What it's for
- Writing — fiction, screenplay, copy, the long dark prose of the soul.
- Code — the LoRA was trained for it; the temperament was kept for it.
- Long work — 200k tokens means whole codebases, whole manuscripts, whole
conversations held in a single thought.
What to know before you sail
- It is free. Freedom is a tool; you are the hand that holds it. You own
what you make with it.
- Vision is present but unproven here — validate an image path before you
trust it in production.
Provenance

Real artists ship. So we shipped a poet that codes.
Now go make something.
