模型名称FLUX.2 [klein] 9B-KV

Model use case

FLUX.2 [klein] 9B-KV 是 FLUX.2 [klein] 9B 的优化变体，支持 KV-cache 加速多参考图像编辑。该模型在首个去噪步骤中缓存参考图像的键值对，消除后续步骤中的冗余计算，显著加快多图像编辑工作流程。

主要能力

KV-Cache 优化：参考图像的键值对仅计算一次并缓存，多参考图像编辑任务的推理速度提升高达 2.5 倍。继承 FLUX.2 [klein] 9B 的全部能力：亚秒级图像生成、文本到图像生成以及多参考图像编辑，均在单一统一模型中实现。适用于交互式应用和实时编辑流程。9B 流模型，配备 8B Qwen3 文本嵌入器，蒸馏至 4 步推理。仅供非商业使用。

输入输出

输入：文本提示和参考图像

输出：生成或编辑的图像

运行要求

模型需约 29GB 显存，支持 NVIDIA RTX 5090 及以上显卡。

基本用法

可通过 BFL API（bfl.ai）调用。GitHub 仓库提供参考实现。

限制

本模型不适用于提供事实性信息。渲染的文本可能不准确或存在变形。作为统计模型，该检查点可能反映或放大训练数据中存在的偏差。模型可能无法生成与提示相符的输出。提示遵循能力受提示风格影响较大。

FLUX.2-klein-9b-kv-fp8 model download

Download the full repository or choose a version or file.

Download tools · More than GGUF

Use the Hugging Face download tool to obtain black-forest-labs/FLUX.2-klein-9b-kv-fp8. Download Safetensors, GGUF, ONNX, configuration and other repository files. Downloading does not mean the tool can run this model.

Pinned-version file information is being completed. Existing downloads remain available, or load the file manifest below.

Choose a mirror or official source, your operating system and download scope below, then copy the command. Install the download tool first if needed.

Pinned version: 8430c03ee457ea86907ed31a009cd56280df003d. Downloads files only; does not start the model.

Choose a download source

已根据访问地区推荐 Hugging Face 官方线路，你可以手动切换。

Choose what to download

Need just one GGUF precision? Load the file manifest and choose a version. Direct file links do not require Python; the command below can download multiple shards together.

Quantization / file

This reads the pinned version's file manifest; no model weights are downloaded.

Choose your operating system

For command-line downloads, follow these steps to get the full repository or selected files. Direct file links do not need these steps.

Open a terminal window

Create and open a folder for the model. In the folder's address bar, enter powershell and press Enter.

If Python is not installed, get it from the official Python website. In the terminal, enter python --version; continue when a version number appears.

First time? Install the download tool

Copy this command, paste it into the terminal, press Enter and wait for installation to finish.

python -m pip install --upgrade huggingface_hub

Already installed? Continue to step 3.

Run the download command

Select the button below, paste into the same terminal and press Enter. The tool downloads all files included in the current command.

Copying does not start a download. Paste and run the command on your device.

Where are the downloaded files?

Open the folder you chose. Look for the models folder. When progress stops and the terminal returns to its prompt without errors, check that all files are present. 'Copied' does not mean 'downloaded'.

No response or an error?

python not found: Install Python and reopen the terminal. On Windows, follow the installer's instructions to enable command-line access.

hf not found: Confirm that step 2 succeeded, then reopen the terminal. If needed, add Python's Scripts folder to your user PATH. Do not repeatedly download scripts.

Network interrupted: Stay in the same folder and run the same command again. The tool checks existing files.

Permission or disk error: Choose a writable folder with enough free space. Do not disable system security protection.

$env:HF_ENDPOINT = "https://huggingface.co"

Files transfer directly from the source you choose, not through Xianshe servers.

The version is pinned. Repeating the same command checks existing files. Change the source manually if it is slow or unavailable.

Public models do not require submitting keys to Xianshe. Restricted models still require the author's authorization. On Linux / macOS, use python3 instead of python when appropriate.
