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.
Telnyx FAQs
What models does Telnyx Inference API offer?
As of October 2026: GLM-5.3 Flash ($0.135/$0.45 per 1M tokens, cached $0.027), Kimi K2.6 ($0.665/$4.00), DeepSeek V4 Flash ($0.130/$0.260), and MiniMax-M3 ($0.270/$1.100). All are OpenAI-compatible. See telnyx.com/pricing/inference-api for current rates.
Is Telnyx Inference API OpenAI-compatible?
Yes. Telnyx provides an OpenAI-compatible REST API, so you can use it as a drop-in replacement in any application that supports custom base URLs.
Does Telnyx offer prompt caching?
Yes, on GLM-5.3 Flash. Cached input tokens are billed at $0.027/1M vs $0.135/1M standard.
