Black Forest Labs
FLUX 1.1 Pro Ultra — the quality benchmark for commercial image generation
Black Forest Labs created FLUX, the model family that has become the quality benchmark for both open and commercial image generation. FLUX 1.1 Pro Ultra produces photorealistic images at up to 4MP resolution. The 2026 lineup adds FLUX 1.1 Pro Ultra (highest quality), FLUX 1.1 Pro (production), FLUX.1 Dev (open-weight, fine-tuning), and FLUX.1 Schnell (open-weight, fastest). FLUX models are available via the BFL API and through Replicate, fal.ai, and other inference platforms.

Frequently asked questions
Black Forest Labs FAQs
What is the difference between FLUX 1.1 Pro Ultra and FLUX.1 Dev?
FLUX 1.1 Pro Ultra is a commercial API model offering the highest quality output at up to 4MP resolution. FLUX.1 Dev is an open-weight model available for self-hosting and fine-tuning, with slightly lower quality than Pro Ultra but full weight access.
How does FLUX compare to Stable Diffusion 3.5?
FLUX consistently outperforms SD 3.5 on image quality benchmarks, particularly for photorealism and prompt adherence. FLUX Schnell is also significantly faster than SD 3.5 for equivalent quality.
Where can I access FLUX models?
FLUX models are available via the BFL API directly, and through Replicate, fal.ai, Novita AI, and other inference platforms. FLUX.1 Dev and Schnell weights are also available on Hugging Face for self-hosting.
Volcano Engine Doubao FAQs
What is Doubao Seed 2.1?
Doubao Seed 2.1 is ByteDance's latest LLM series, available via Volcano Engine. Pro is the frontier reasoning tier and Turbo is the balanced tier. Both support Chinese and English.
How much does the Doubao API cost?
Doubao Seed 2.1 Pro is $6.00/$30.00 per 1M input/output tokens. Doubao Seed 2.1 Turbo is $3.00/$15.00 per 1M tokens. See the Volcano Engine pricing page for current rates.
Is Doubao available outside China?
Doubao is available via Volcano Engine's international API, but the platform and documentation are primarily Chinese. Western developers may find setup more involved than with OpenAI-compatible providers.
