This model card documents Ornith-1.0-9B, the most lightweight member of the Ornith family, designed for efficient single-GPU deployment.
Ornith-1.0-9B is a dense ~9B model (≈19 GB in bf16), so it serves comfortably on a single 80GB GPU. The recipes below stand up an OpenAI-compatible server; add --tensor-parallel-size / --tp if you want to shard across more GPUs.
bash
vllm serve deepreinforce-ai/Ornith-1.0-9B \--served-model-name Ornith-1.0-9B \--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

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; Ornith-1.0-9B requires transformers >= 5.8.1.
python
from transformers import AutoModelForCausalLM, AutoTokenizermodel_name = "deepreinforce-ai/Ornith-1.0-9B"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]:]# The reply contains a <think> ... </think> reasoning block followed by the answer.content = tokenizer.decode(output_ids, skip_special_tokens=True)print(content)
To split the reasoning trace from the final answer, parse on the </think> marker:
python
text = tokenizer.decode(output_ids, skip_special_tokens=True)if "</think>" in text:reasoning, answer = text.split("</think>", 1)reasoning = reasoning.replace("<think>", "").strip()answer = answer.strip()else:reasoning, answer = "", text.strip()
Once a vLLM or SGLang server is running, talk to it with any OpenAI-compatible client.
python
from openai import OpenAIclient = OpenAI(base_url="http://localhost:8000/v1",api_key="EMPTY", # any non-empty string works for a local server)response = client.chat.completions.create(model="Ornith-1.0-9B",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# reasoning_content holds the <think> trace; content holds the final answer.print("reasoning:", getattr(message, "reasoning_content", None))print("answer:", message.content)
You can also stream tokens, or hand the model tools — Ornith-1.0-9B emits well-formed function calls that the server parses into the standard tool_calls field:
python
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="Ornith-1.0-9B",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)# -> get_weather {"city": "Paris"}
You can point any OpenAI-compatible SDK (Python, Node.js, etc.) or curl at the same /v1/chat/completions endpoint.
Ornith-1.0-9B excels in tool-calling and agentic coding capabilities.
Because Ornith-1.0-9B 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 Ornith-1.0-9B to tools through an MCP server.
python
import osfrom openai import OpenAIclient = 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="deepreinforce-ai/Ornith-1.0-9B",messages=messages,tools=tools,temperature=0.6,top_p=0.95,)print(response.choices[0].message)
Examples of using Ornith with agent harness:
bash
# Hermes talks to any OpenAI-compatible endpoint — point it at your Ornith server.export OPENAI_BASE_URL="http://localhost:8000/v1"export OPENAI_API_KEY="EMPTY"export MODEL="deepreinforce-ai/Ornith-1.0-9B"
bash
# Both runtimes load a GGUF build of Ornith (publish one at deepreinforce-ai/Ornith-1.0-9B-GGUF).# llama.cpp — serve an OpenAI-compatible API on port 8000.llama-server -hf deepreinforce-ai/Ornith-1.0-9B-GGUF --port 8000 -c 262144# Ollama — pull and chat with the same GGUF straight from Hugging Face.ollama run hf.co/deepreinforce-ai/Ornith-1.0-9B-GGUF
bash
# OpenClaw talks to any OpenAI-compatible endpoint — point it at your Ornith server.export OPENAI_BASE_URL="http://localhost:8000/v1"export OPENAI_API_KEY="EMPTY"export OPENAI_MODEL="deepreinforce-ai/Ornith-1.0-9B"
bash
pip install unsloth# Load Ornith for fast local inference or fine-tuning (Python):# from unsloth import FastLanguageModel# model, tokenizer = FastLanguageModel.from_pretrained(# "deepreinforce-ai/Ornith-1.0-9B",# max_seq_length=262144,# load_in_4bit=True,# )
bash
pip install openhands-ai# OpenHands routes through LiteLLM; the "openai/" prefix selects the OpenAI-compatible path.export LLM_MODEL="openai/deepreinforce-ai/Ornith-1.0-9B"export LLM_BASE_URL="http://localhost:8000/v1"export LLM_API_KEY="EMPTY"# Launch the CLI (or run the official OpenHands Docker image with the same env vars).openhands
Ornith-1.0-9B is optimized for terminal-based coding agents. Point any OpenAI-compatible coding CLI at your Ornith-1.0-9B endpoint (set OPENAI_BASE_URL and OPENAI_API_KEY) to understand large codebases, automate tedious work, and ship faster.
bash
# Register your local Ornith endpoint as a provider in ~/.config/opencode/opencode.json:## {# "$schema": "https://opencode.ai/config.json",# "provider": {# "ornith": {# "npm": "@ai-sdk/openai-compatible",# "name": "Ornith (local)",# "options": { "baseURL": "http://localhost:8000/v1", "apiKey": "EMPTY" },# "models": { "deepreinforce-ai/Ornith-1.0-9B": { "name": "Ornith-1.0-9B" } }# }# }# }opencode
