Pi new

How to use osirisbrain/OsirisCortex-v7-MLX with Pi:

Start the MLX server

# Install MLX LM:
uv tool install mlx-lm
# Start a local OpenAI-compatible server:
mlx_lm.server --model "osirisbrain/OsirisCortex-v7-MLX"

Configure the model in Pi

# Install Pi:
npm install -g @mariozechner/pi-coding-agent
# Add to ~/.pi/agent/models.json:
{
  "providers": {

mlx_lm.server --model "osirisbrain/OsirisCortex-v7-MLX"
# Calling the OpenAI-compatible server with curl
curl -X POST "http://localhost:8000/v1/chat/completions" \
   -H "Content-Type: application/json" \
   --data '{
     "model": "osirisbrain/OsirisCortex-v7-MLX",
     "messages": [
       {"role": "user", "content": "Hello"}
     ]
   }'

OsirisCortex-v7-MLX

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

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)
