# Ornith-1.5-122B

Chirp Chirp! 🐦 We are introducing Ornith-1.5, a major step toward building foundation models through end-to-end self-improvement.

Ornith-1.5 extends Ornith-1.0 (which was developed on top of Qwen3.5 and Gemma4 with additional continued pretraining, mid-training, and post-training) by expanding the self-improvement loop from scaffold and rollout optimization to jointly optimizing task generation, scaffold construction, and solution rollouts. Rather than relying on a fixed set of human-curated tasks and manually designed harnesses, Ornith-1.5 continuously generates new training tasks, discovers effective strategies for solving them, and improves the policy through reinforcement learning. For more details on the task, harness, and rollout reward design, please refer to our [blog](https://ornith.ai/ornith_1_5.html).

## Ornith 1.5 122B

This model card documents **Ornith-1.5-122B**, the most capable and efficient.member of the Ornith-1.5 family — a 122B MOE model designed for efficient single-GPU deployment, and edge-deployable on mobile devices via its quantized Ornith-1.5-122B-Mobile variant.

### Serving Ornith-1.5-122B

Ornith-1.5-122B is a MOE 122B model, so it serves 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.

*  vLLM

```bash
vllm serve ornith-ai/Ornith-1.5-122B --served-model-name Ornith-1.5-122B --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


```bash
python -m sglang.launch_server --model-path ornith-ai/Ornith-1.5-122B --served-model-name Ornith-1.5-122B --host 0.0.0.0 --port 8000 --context-length 262144 --mem-fraction-static 0.85 --tool-call-parser qwen3_coder --reasoning-parser qwen3
```

#### For Long-Context

Ornith-1.5-122B handles context windows of up to 262,144 tokens. When a task's combined input and output must go beyond this limit, we suggest extending the effective window with RoPE scaling — YaRN is the technique we validate against, and it is already built into both vLLM and SGLang. With a scaling factor of 4.0, the usable window grows to roughly 1M tokens.

You can turn YaRN on in either of two ways:

- **Edit the checkpoint's `config.json`.** Add a `rope_scaling` block to the model configuration:

  ```json
  {
      "rope_scaling": {
          "rope_type": "yarn",
          "factor": 4.0,
          "original_max_position_embeddings": 262144
      }
  }
  ```

- **Override at launch time.** Leave the checkpoint untouched and extend the serve commands above with the equivalent flags.

  vLLM:

  ```bash
  VLLM_ALLOW_LONG_MAX_MODEL_LEN=1 vllm serve ornith-ai/Ornith-1.5-122B ... --hf-overrides '{"rope_scaling": {"rope_type": "yarn", "factor": 4.0, "original_max_position_embeddings": 262144}}' --max-model-len 1000000
  ```

  SGLang:

  ```bash
  SGLANG_ALLOW_OVERWRITE_LONGER_CONTEXT_LEN=1 python -m sglang.launch_server ... --json-model-override-args '{"rope_scaling": {"rope_type": "yarn", "factor": 4.0, "original_max_position_embeddings": 262144}}' --context-length 1000000
  ```

<div style="border-left:4px solid #FD8E5B;background:rgba(253,142,91,0.1);border-radius:6px;padding:12px 16px;font-family:-apple-system,BlinkMacSystemFont,'Segoe UI',Roboto,sans-serif;font-size:14px;line-height:1.6">
<div style="font-weight:700;color:#FD8E5B;margin-bottom:6px">📝 NOTE</div>
<p style="margin:0">Open-source runtimes implement YaRN <i>statically</i>: the same scaling factor is applied to every request regardless of its length, which can slightly hurt quality on ordinary-length inputs. Only enable <code style="background:rgba(253,142,91,0.15);padding:1px 5px;border-radius:4px">rope_scaling</code> when your workload genuinely needs the longer window, and size <code style="background:rgba(253,142,91,0.15);padding:1px 5px;border-radius:4px">factor</code> to match it — the target window is roughly <code style="background:rgba(253,142,91,0.15);padding:1px 5px;border-radius:4px">factor</code> × 262,144, so if your requests top out around 524,288 tokens, <code style="background:rgba(253,142,91,0.15);padding:1px 5px;border-radius:4px">factor: 2.0</code> is the better setting.</p>
</div>

### Using Ornith-1.5-122B via the Chat Completions API

Once a vLLM or SGLang server is running, talk to it with any OpenAI-compatible client.

#### Basic Usage

```python
from openai import OpenAI

client = 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-1.5-122B",
    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-1.5-122B 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-1.5-122B",
    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.


## Agentic Usage

Ornith-1.5-122B exposes an OpenAI-compatible endpoint with tool calling, it works out of the box with standard agent frameworks. 

**Examples of using Ornith with agents:**


#### Ollama 
```bash
ollama run ornith-1.5:122b
```


#### Atomic.chat
```bash
# Both runtimes load a GGUF build of Ornith (publish one at ornith-ai/Ornith-1.5-122B-GGUF).

# llama.cpp — serve an OpenAI-compatible API on port 8000.
llama-server -hf hf.co/ornith-ai/Ornith-1.5-122B-GGUF --port 8000 -c 262144
```

#### llama.cpp
```bash
# Both runtimes load a GGUF build of Ornith (publish one at ornith-ai/Ornith-1.5-122B-GGUF).

# llama.cpp — serve an OpenAI-compatible API on port 8000.
llama-server -hf hf.co/ornith-ai/Ornith-1.5-122B-GGUF --port 8000 -c 262144
```

#### Hermes Agent
```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="ornith-ai/Ornith-1.5-122B"
```

#### OpenClaw

```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="ornith-ai/Ornith-1.5-122B"
```

#### Unsloth Studio

```bash
pip install unsloth

# Load Ornith for fast local inference or fine-tuning (Python):
#   from unsloth import FastLanguageModel
#   model, tokenizer = FastLanguageModel.from_pretrained(
#       "unsloth/Ornith-1.5-122B-GGUF",
#       max_seq_length=262144,
#       load_in_4bit=True,
#   )
```


### Coding CLIs

Ornith-1.5-122B is optimized for terminal-based coding agents. Point any OpenAI-compatible coding CLI at your Ornith-1.5-122B endpoint (set `OPENAI_BASE_URL` and `OPENAI_API_KEY`) to understand large codebases, automate tedious work, and ship faster.

#### OpenCode
```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": { "ornith-ai/Ornith-1.5-122B": { "name": "Ornith-1.5-122B" } }
#     }
#   }
# }
