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

Описание и применение

INT8‑версия FLUX 3 Image Klein успешно работает на RTX 4070, генерируя 1 МП изображения за <9 с, что делает локальную генерацию доступной для небольших команд.

Задача

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

Результат

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.

Рабочий процесс

• 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)

Доказательства

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

Источник

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

Источник

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