## ๐ฅ News
- **2026-08-12**: ๐ฅ We release the ExoMind technical report, official project page,
and public repository.
## Overview
ExoMind-9B is the compact ExoMind checkpoint, fine-tuned from
[Qwen3.5-9B](https://huggingface.co/Qwen/Qwen3.5-9B) for lower-resource
experimentation in scientific reasoning and agentic research. It follows the
same extended-mind-inspired approach, organizing the model, specialized
interaction objects, and autonomous interaction processes as one system.
## Highlights
- **Compact scientific checkpoint:** supports resource-conscious experiments
with the ExoMind reasoning and interaction paradigm.
- **Scientific interaction:** works with source discovery, evidence grounding,
executable verification, and observation integration workflows.
- **Progressive CoI training:** develops intrinsic reasoning and interaction
behavior from selected pure-reasoning and interaction trajectories.
- **Multimodal foundation:** retains the image-text capabilities of its Qwen3.5
base model.
## Quick Start
Use a recent vLLM or SGLang release with Qwen3.5 support. The examples below
use the checkpoint's configured maximum context length of 262,144 tokens.
### vLLM
```bash
vllm serve AI4SGI/ExoMind-9B \
--port 8000 \
--tensor-parallel-size 1 \
--max-model-len 262144 \
--reasoning-parser qwen3 \
--enable-auto-tool-choice \
--tool-call-parser qwen3_coder
```
### SGLang
```bash
python -m sglang.launch_server \
--model-path AI4SGI/ExoMind-9B \
--host 0.0.0.0 \
--port 8000 \
--tp-size 1 \
--context-length 262144 \
--reasoning-parser qwen3 \
--tool-call-parser qwen3_coder
```
### OpenAI-Compatible API
```python
from openai import OpenAI
client = OpenAI(base_url="http://localhost:8000/v1", api_key="EMPTY")
response = client.chat.completions.create(
model="AI4SGI/ExoMind-9B",
messages=[
{
"role": "user",
"content": "Develop a testable hypothesis and a rigorous verification plan for: ...",
}
],
temperature=1.0,
top_p=0.95,
extra_body={"top_k": 20},
)
print(response.choices[0].message.content)
```
