I Ran FLUX 3 Image Klein on My RTX 4070 — Here's What Actually Happened

说明与用途

FLUX 3 Image Klein 的 INT8 版本在 RTX 4070 上运行，生成 1 MP 图像耗时不到 9 秒，使本地生成对小团队可行。

问题

Running a large 5.6B parameter image generation model locally on consumer hardware was uncertain and potentially slow.

结果

The INT8 version runs efficiently on an RTX 4070, producing 1 MP images in <9 s, proving local inference viable for small teams and indie projects.

工作流

• 1. Install FLUX 3 Image Klein INT8 build on RTX 4070
• 2. Load model in ComfyUI
• 3. Generate a 1 MP image
• 4. Measure generation time (under 9 s)

证据

The INT8 build fits in 8GB VRAM and generates a 1MP image in under 9 seconds through ComfyUI.

来源

The model is open weights under the FLUX Kommunity License, which means free commercial use if you're under $5M revenue.

Combined with LoRA fine-tuning support from day one, this changes what's realistic for small teams or indie projects.
