# Free Qwen 3.8 Max

Try Qwen 3.8 Max with text and image inputs. Thinking mode is enabled by default; its reasoning summary appears in a collapsible panel while the final answer streams token by token.

The Space also includes a box-prompting playground inspired by [Roboflow's Qwen 3.8 Max evaluation](https://blog.roboflow.com/qwen3-8-max/): click and drag positive and optional negative bounding boxes directly over an image, then ask Qwen to find similar objects. Three ready-made presets demonstrate shape, color, and size matching; each loads an editable instruction and example boxes. Reasoning and JSON tokens stream separately, then detection results are parsed from normalized XYXY coordinates and rendered back onto the original image.

A separate zero-shot object-detection tab accepts a plain-language detection prompt—or a **Detect everything** option—and renders class-labeled boxes without requiring examples. It includes ready-made shape, vehicle, and product-inventory prompts and uses the same streamed reasoning and JSON presentation.

This is an unofficial community demo, generously backed by a limited pool of Qwen API tokens. Availability is best-effort and the demo may be paused when the pool is exhausted.

## Configuration

The Space expects one secret:

- `DASHSCOPE_API_KEY`: a DashScope International API key with access to `qwen3.8-max`

## Local development

```bash
uv sync
DASHSCOPE_API_KEY=... uv run python app.py
```

The app limits request concurrency, image size, queue depth, and per-session request frequency to keep the public token pool useful for more people.
