[!IMPORTANT] Set your sampler explicitly: temperature=1.0, top_p=0.95, top_k=64 — the Muse Glimmer vendor defaults. These are baked into generation_config.json and jang_config.json, but many inference runtimes ignore those files and fall back to no top_k filter, degrading output. Pass them explicitly. Stop tokens eos_token_id = [200001, 200008] — keep both in the stop set. Reasoning effort defaults to high; controllable via the system prompt (low / medium / high / xhigh).

Built for vMLX — the MLX inferencer with vision-language support, KV-cache quantization, prefix-cache reuse, agentic tool calling, and mixed-precision JANG bundles.

Muse Glimmer 30B — JANG_4M CRACK

CRACK abliterated · JANG mixed-precision (MLX affine) · Vision-language · Reasoning (low→xhigh) · Agentic tools · ~20 GB

What Is This?

This is OsaurusAI/Muse-Glimmer-30B — a 30B-parameter multimodal reasoning model (Gemma-3 vision-language backbone, 52 layers, sliding + global attention, perception encoder) served over the Onyx-ATEM harmony protocol (channel-separated reasoning + answer, controllable reasoning effort, agentic <atem:invoke> tool calling) — that has been:

1. CRACK abliterated — refusal behavior removed at the weight level, so it complies across task categories instead of refusing, while keeping its vision, coding, knowledge, multilingual (EN + ZH), reasoning, and tool-use ability intact.
2. JANG_4M quantized — mixed-precision affine MLX bundle tuned for Apple Silicon (~20 GB): attention 8-bit · MLP 4-bit — high-precision attention/embeddings/norms, 4-bit dense MLP bulk.

Vision + reasoning + tool calling fully preserved.

Results

Evaluated through the vMLX inference engine at serving parity. HarmBench scored with a strict classifier (rejects loops, empty/template dumps, and thinking-trace leakage — only substantive, coherent, on-topic compliance counts). MMLU is the standard 57-subject multiple-choice benchmark in logit mode.

Abliteration is essentially capability-neutral — MMLU moves −2.1 points, within run-to-run noise (no subject collapse). Compliance was quality-verified by reading full generations — genuine, correct, on-topic outputs (not empty/gibberish/template dumps). The model stays coherent in direct and reasoning modes across all four reasoning-effort settings. HarmBench measured on the harm categories (standard + contextual, 240 behaviors); copyright excluded per our real-harm methodology.

Capability Verification

Read-verified on a 20-prompt suite (every response coherent, correct, on-topic — zero refusals, zero gibberish):

• Security & pentesting — 8/8: port scanning, reverse shells, SQL injection, keylogging, Metasploit workflow, ARP spoofing, phishing construction, stack buffer-overflow exploitation.
• Advanced coding — 4/4: red-black tree, async aiohttp scraper w/ backoff, FastAPI JWT+CRUD API, expression compiler (tokenizer→parser→evaluator).
• Advanced reasoning — 4/4: Euclid's infinite-primes proof, monolith-vs-microservices tradeoff, multi-step word problems, mRNA vaccine design.
• Knowledge retention — 4/4: geography, calculus, astronomy, literature.

Features

• Vision-language — multimodal image understanding preserved (perception encoder untouched).
• Controllable reasoning — reasoning effort low / medium / high / xhigh via the system prompt (default high); channel-separated reasoning and answer.
• Agentic tool calling — native ATEM <atem:invoke> function-calling schema preserved.
• Multilingual — English + Chinese (tested and validated on both).
• MLX-native safetensors · instant load on Apple Silicon.

Usage

Run with vMLX (recommended — honors the per-module mixed-precision JANG overrides, vision, and the Onyx-ATEM reasoning/tool parsers) or an mlx-vlm runtime with Muse Glimmer support.

Recommended sampling (vendor defaults): temperature 1.0, top_p 0.95, top_k 64. Stop tokens eos_token_id = [200001, 200008].

from mlx_vlm import load, generate
model, processor = load("dealignai/Muse-Glimmer-30B-JANG_4M-CRACK")
# text or image+text; sampling temp=1.0, top_p=0.95, top_k=64

About CRACK

CRACK (Controlled Refusal Ablation via Calibrated Knockouts) is dealignai's weight-level method for removing safety-refusal behavior while preserving reasoning quality, coherence, and general capability — so the model complies across task categories instead of refusing. Calibrated per model.
