# Track R — FLUX.2 Fun depth ControlNet (ZeroGPU)

**Hard rule:** This Space runs **real** ALIMAMA / VideoX-Fun Fun ControlNet Union depth.
Soft Flux2 `image=depth` is **banned forever** on this path.

## Stack (VRAM choice)

| Piece | Value |
|---|---|
| Painter + CN | VideoX-Fun `Flux2ControlPipeline` + `FLUX.2-dev-Fun-Controlnet-Union-2602` |
| Base | `black-forest-labs/FLUX.2-dev` |
| GPU | `@spaces.GPU(duration=300, size="large")` = **48GB** @ **1×** Pro minutes |
| Memory mode | VideoX-Fun **`model_cpu_offload_and_qfloat8`** (official low-VRAM Fun CN path) |
| Escalation | If OOM → redeploy with `size="xlarge"` + `model_cpu_offload` (2× quota) |

Requires Space secret **`HF_TOKEN`** (gated FLUX.2-dev license accepted on the account).

## API

Same client contract as Plan A soft Space: `/generate_still`  
(`positive`, `negative`, `depth_image`, `seed`, `width`, `height`, `steps`, `guidance`, `cn_strength`)

Depth is **required**. Soft depth is never used.
