Ornith-1.0-9B
Aloha! 🌺 Today, we are releasing Ornith-1.0, a self-improving family of open-source models for agentic coding.
Highlights:
- State-of-the-Art Coding Agents: Available in 9B-Dense, 31B-Dense, 35B-MoE, and 397B-MoE (post-trained on top of Gemma 4 and Qwen 3.5), achieving state-of-the-art performance among open-source models of comparable size on coding benchmarks such as Terminal-Bench 2.1, SWE-Bench, NL2Repo and OpenClaw.
- Self-Improving Training Framework: Ornith-1.0 employs RL to learn to generate not only solution rollouts, but also the scallfold that drive those rollouts. By jointly optimizing the scaffold and the resulting solution, the model discovers better search trajectories and generates higher-quality solutions.
- Licence: MIT licensed, globally accessible, and free from regional limitations.
Ornith 1.0 9B
This model card documents Ornith-1.0-9B, the most lightweight member of the Ornith family, designed for efficient single-GPU deployment.
Benchmarks
Quickstart
Serving Ornith-1.0-9B
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.

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.
from transformers import AutoModelForCausalLM, AutoTokenizer
model_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]:]
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:
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()
Using Ornith-1.0-9B 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="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
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:
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)
You can point any OpenAI-compatible SDK (Python, Node.js, etc.) or curl at the same /v1/chat/completions endpoint.
Agentic Usage
Ornith-1.0-9B excels in tool-calling and agentic coding capabilities.
Agent Frameworks
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.
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="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:

# 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.

# max_seq_length=262144,
# load_in_4bit=True,
# )
OpenHands

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).

Coding CLIs
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.
OpenCode
# 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" } }
