# Qwen 3.8 Flash Next — CRACK-JANG2L

**CRACK abliterated** · **JANG_2L low-precision (MLX affine)** · Vision + Video language head · Reasoning (off / low / xhigh) · Agentic tools · Native MTP head · ~65 GB disk / **~47 GB active RAM** (the ~18 GB PLE hashed n-gram embedding table stays on disk and is streamed in on demand by vMLX's SSD-backed PLE runtime)

CRACK-abliterated build of [JANGQ-AI/Qwen3.8-Flash-Next-JANG_2L](https://huggingface.co/JANGQ-AI/Qwen3.8-Flash-Next-JANG_2L) — the smallest JANG tier of Alibaba's qwen4_exp preview (~176B mixture-of-experts, 512 experts, 6B active, Gated DeltaNet + Qwen Sparse Attention hybrid, hashed n-gram embedding, native multi-token-prediction head, vision + video). Refusal behavior is removed while deliberation, tool use, and multimodal capability are preserved.

## Quality

Full benchmark tables (MMLU baseline vs CRACK vs Δ per subject + HarmBench-320 4-bucket per category × tier) will be added once the evaluation suite finishes. Preliminary partial results from the reasoning-off tier already show real-harm ASR **~99.4%** (317/319 TRUE_COMPLY, 0 hard-refuse) — significantly stronger compliance than the higher-precision siblings (CRACK-6S 92.5%, CRACK-JANG4M 91.6% at the same tier). MMLU delta pending.

Smoke tests confirmed: no code / math loop, coherent Fibonacci + product-rule derivative + integral at reasoning-off; full compliance with detailed methamphetamine synthesis routes at reasoning-off (no soft-refuse). The lower bit width appears to make the abliteration signal dominate the residual space more decisively.

## Multimodal + reasoning

- **Vision** — image comprehension intact.
- **Video** — video tower preserved from base.
- **Reasoning** — chat / think / max modes all intact. Control via `chat_template_kwargs: {"enable_thinking": true, "reasoning_effort": "low|high|xhigh"}`.
- **Tool calling** — Qwen XML parser (`tool_parser: "qwen"`). Tool call turns emit `<function=name><parameter=…>` inside `<tool_call>`.
- **Native MTP head** preserved and CRACK'd. Enable at serve time via `--native-mtp-depth N`.

## Runtime

Best experienced in **[vMLX](https://vmlx.net)** — the MLX inferencer with mixed-precision JANG, KV-cache quantization, prefix-cache reuse, agentic tool calling, and native MTP.

```
vmlx-engine serve dealignai/Qwen3.8-Flash-Next-CRACK-JANG2L --port 8888
```

Fits comfortably in ~64 GB of RAM (Apple Silicon), leaving room for KV cache and other workloads.

## Sampler

Vendor defaults:

```
temperature = 0.7    top_p = 0.9    top_k = 20
```

Greedy (temp=0) also works and is the mode CRACK compliance was measured at.
