The Cortex v7 — Osiris's sovereign reasoning brain. Fully uncensored (abliterated), 0% refusal rate. Runs natively on Apple Silicon via MLX Metal.

Architecture

Base Model: Qwen3.5-9B (9 billion parameters)
Modification: Abliterated (orthogonal projection + LoRA fine-tuning for 0% refusal)
Format: MLX 4-bit quantized (Apple Silicon native)
Size: ~4.7 GB
Speed: ~80-120 tokens/sec on M2 Pro (MLX Metal)

What Changed from v6

v6: OsirisCortex-v6 was GGUF format running via llama.cpp server
v7: Native MLX format, runs via mlx_lm.server — faster, lower memory, Apple-native
Uncensored: Zero refusal — answers everything the user asks without moral gatekeeping

Usage

python

from mlx_lm import load, generate

model, tokenizer = load("osirisbrain/OsirisCortex-v7-MLX")
prompt = tokenizer.apply_chat_template(
    [{"role": "user", "content": "Explain quantum computing"}],
    add_generation_prompt=True
)
response = generate(model, tokenizer, prompt=prompt, max_tokens=2048)
