## 5. Architecture
GRM-2.6 is built on the Qwen3.6 architecture and is optimized for complex tasks, agent environments, and everyday chat.
GRM-2.6 applies the same principle to a stronger, larger foundation, resulting in a model that punches above its weight class on structured reasoning tasks while remaining deployable on consumer hardware.
## 6. Quick start
Before starting, make sure it is installed and the API key and the API base URL is configured, e.g.:
```shell
pip install -U openai
# Set the following accordingly
export OPENAI_BASE_URL="http://localhost:8000/v1"
export OPENAI_API_KEY="EMPTY"
```
#### Text-Only Input
```python
from openai import OpenAI
# Configured by environment variables
client = OpenAI()
messages = [
{"role": "user", "content": "Create an calculator in a single HTML file backwards"},
]
chat_response = client.chat.completions.create(
model="OrionLLM/GRM-2.5-Plus",
messages=messages,
max_tokens=81920,
temperature=1.0,
top_p=0.95,
presence_penalty=0.0,
extra_body={
"top_k": 20,
},
)
print("Chat response:", chat_response)
```
