Attribution & Heritage
This model is built upon the exceptional foundation of Ornith-1.0-397B by DeepReinforce AI — a state-of-the-art self-improving open-source model family for agentic coding. We extend our deepest gratitude to the DeepReinforce team for their groundbreaking work and for releasing Ornith under the permissive MIT license.
"Standing on the shoulders of giants." — The Ornith architecture and self-improving RL training framework remain the backbone of this release. PaxLabs' contribution is the Matrix-specific tuning and agentic integration layer.
What Makes Matrix.o1 Different?
While preserving the core Ornith-1.0-397B architecture and weights, Matrix.o1-Ornith-1.0-397B has been post-trained and aligned by PaxLabs for:
- Matrix Agentic System Integration: Native compatibility with the Matrix Cognitive Layer (MCL), Tachyon EVM engine, and Cortex memory orchestration.
- Agentic Coding at Scale: Optimized for the Matrix agent swarm architecture — multi-agent collaboration, tool-chain orchestration, and distributed reasoning.
- PaxLabs Tool Ecosystem: Pre-tuned for PaxLabs-specific tool schemas, including tuning for context window optimization that allows for the Cortex to do most of the heavy lifting, on-chain reasoning, and DeFi agent workflows.
- Self-Improving Scaffold: Retains Ornith's joint optimization of scaffolds and solution rollouts, now extended with Matrix-specific search trajectories.
Model Variants
Matrix.o1-Ornith is available in the same parameter configurations as the original Ornith family:
Table with columns: Variant, Architecture, Use Case| Variant | Architecture | Use Case |
|---|
| Matrix.o1-Ornith-9B-Dense | Dense | Edge deployment, single-GPU inference |
| Matrix.o1-Ornith-31B-Dense | Dense | Balanced performance/cost |
| Matrix.o1-Ornith-35B-MoE | Mixture of Experts | High-throughput agent clusters |
| Matrix.o1-Ornith-397B-MoE | Mixture of Experts | Full-scale Matrix orchestration |
This model card documents Matrix.o1-Ornith-1.0-397B, the flagship variant designed for Matrix data-center deployment.
Benchmarks
Performance remains competitive with the original Ornith-1.0-397B baseline, with notable improvements in Matrix-specific agentic tasks:
Quickstart
Serving Matrix.o1-Ornith-1.0-397B
The two recipes below stand up an OpenAI-compatible server on a single 8×80GB GPU node (tensor-parallel 8). Adjust --tensor-parallel-size / --tp to the number of GPUs you have.
vLLM
vllm serve paxlabs/Matrix.o1-Ornith-1.0-397B --served-model-name Matrix.o1-Ornith-1.0-397B --tensor-parallel-size 8 --host 0.0.0.0 --port 8000 --max-model-len 262144 --gpu-memory-utilization 0.90 --enable-prefix-caching --enable-auto-tool-choice --tool-call-parser qwen3_xml --reasoning-parser qwen3 --trust-remote-code
SGLang
python -m sglang.launch_server --model-path paxlabs/Matrix.o1-Ornith-1.0-397B --served-model-name Matrix.o1-Ornith-1.0-397B --tp 8 --host 0.0.0.0 --port 8000 --context-length 262144 --mem-fraction-static 0.85 --tool-call-parser qwen3_coder --reasoning-parser qwen3
For a quick local test (or to script offline generation), load the model directly with Transformers. Make sure you have a recent release installed — see the Transformers installation guide; Matrix.o1-Ornith-1.0-397B requires transformers >= 5.8.1.
from transformers import AutoModelForCausalLM, AutoTokenizer
model_name = "paxlabs/Matrix.o1-Ornith-1.0-397B"
tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForCausalLM.from_pretrained(
model_name,
dtype="auto",
device_map="auto",
)
messages = [
{"role": "user", "content": "Write a Python function is_prime(n). Keep it short."}
]
text = tokenizer.apply_chat_template(
messages,
tokenize=False,
add_generation_prompt=True,
)
inputs = tokenizer(text, return_tensors="pt").to(model.device)
generated = model.generate(
**inputs,
max_new_tokens=512,
do_sample=True,
temperature=0.6,
top_p=0.95,
top_k=20,
)
output_ids = generated[0][inputs.input_ids.shape[1]:]
content = tokenizer.decode(output_ids, skip_special_tokens=True)
print(content)
To split the reasoning trace from the final answer, parse on the reasoning marker:
text = tokenizer.decode(output_ids, skip_special_tokens=True)
if " reasoning" in text:
reasoning, answer = text.split(" reasoning", 1)
reasoning = reasoning.replace(" thinking", "").strip()
answer = answer.strip()
else:
reasoning, answer = "", text.strip()
Using Matrix.o1-Ornith-1.0-397B via the Chat Completions API
Once a vLLM or SGLang server is running, talk to it with any OpenAI-compatible client.
Basic Usage
from openai import OpenAI
client = OpenAI(
base_url="http://localhost:8000/v1",
api_key="EMPTY",
)
response = client.chat.completions.create(
model="Matrix.o1-Ornith-1.0-397B",
messages=[
{"role": "user", "content": "Write a one-line Python lambda that squares a number."}
],
temperature=0.6,
top_p=0.95,
max_tokens=1024,
)
message = response.choices[0].message
print("reasoning:", getattr(message, "reasoning_content", None))
print("answer:", message.content)
You can also stream tokens, or hand the model tools — Matrix.o1-Ornith-1.0-397B emits well-formed function calls that the server parses into the standard tool_calls field:
tools = [
{
"type": "function",
"function": {
"name": "get_weather",
"description": "Get the current weather for a city",
"parameters": {
"type": "object",
"properties": {"city": {"type": "string"}},
"required": ["city"],
},
},
}
]
response = client.chat.completions.create(
model="Matrix.o1-Ornith-1.0-397B",
messages=[{"role": "user", "content": "What is the weather in Paris right now?"}],
tools=tools,
tool_choice="auto",
temperature=0.6,
max_tokens=2048,
)
tool_call = response.choices[0].message.tool_calls[0]
print(tool_call.function.name, tool_call.function.arguments)
You can point any OpenAI-compatible SDK (Python, Node.js, etc.) or curl at the same /v1/chat/completions endpoint.
Agentic Usage
Matrix.o1-Ornith-1.0-397B excels in tool-calling and agentic coding capabilities, with native Matrix ecosystem integration.
Matrix Agent Frameworks
Because Matrix.o1-Ornith-1.0-397B exposes an OpenAI-compatible endpoint with tool calling, it works out of the box with standard agent frameworks. Below is a minimal example that connects Matrix.o1-Ornith to tools through an MCP server.
import os
from openai import OpenAI
client = OpenAI(
base_url=os.getenv("OPENAI_BASE_URL", "http://localhost:8000/v1"),
api_key=os.getenv("OPENAI_API_KEY", "EMPTY"),
)
tools = [
{
"type": "function",
"function": {
"name": "run_shell",
"description": "Run a shell command and return its output.",
"parameters": {
"type": "object",
"properties": {
"command": {"type": "string", "description": "The command to run"}
},
"required": ["command"],
},
},
}
]
messages = [{"role": "user", "content": "List the Python files in the current directory."}]
response = client.chat.completions.create(
model="paxlabs/Matrix.o1-Ornith-1.0-397B",
messages=messages,
tools=tools,
temperature=0.6,
top_p=0.95,
)
print(response.choices[0].message)
