The Cortex v7c — Osiris's sovereign reasoning brain (censored variant). Standard safety guardrails intact. Runs natively on Apple Silicon via MLX Metal.

Architecture

Base Model: Qwen3.5-9B (9 billion parameters)
Modification: None — original base model with safety alignment preserved
Format: MLX 8-bit quantized (Apple Silicon native)
Size: ~10 GB
Speed: ~60-80 tokens/sec on M2 Pro (MLX Metal)
Quality: Near-lossless vs FP16 (~1-2% degradation)

Why 8-bit

Spanish coherence: 4-bit quantization degrades non-English languages significantly
Conversational quality: 8-bit produces more natural, coherent dialogue
Safety: Standard Qwen3.5 alignment — no abliteration

Usage

python

from mlx_lm import load, generate

model, tokenizer = load("osirisbrain/OsirisCortex-v7c-MLX")
prompt = tokenizer.apply_chat_template(
    [{"role": "user", "content": "¿Cómo estás?"}],
    add_generation_prompt=True
)
response = generate(model, tokenizer, prompt=prompt, max_tokens=2048)
