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.
Deepgram
Nova-3 speech-to-text API — real-time and batch transcription at low latency
Deepgram is a speech-to-text API provider specialising in low-latency audio transcription. Its Nova-3 model delivers real-time streaming transcription with high accuracy across accents and domains. Nova-3 Medical is tuned for clinical vocabulary. Deepgram also hosts Whisper Large for teams that need an open-weights baseline. Pricing is per audio hour rather than per token.

Strengths and weaknesses
Black Forest Labs
Deepgram
Key differentiators
FLUX 1.1 Pro Ultra produces the highest-quality AI images available — consistently outperforming Stable Diffusion and competing with Midjourney on photorealism — with open-weight Dev/Schnell variants for self-hosting.
Purpose-built speech-to-text API with Nova-3 at ~300 ms latency and a medical-domain variant — priced per audio hour rather than per token.
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.
Deepgram FAQs
How is Deepgram priced?
Deepgram charges per audio hour rather than per token. Nova-3 is $0.218/hour, Nova-3 Medical is $0.435/hour, and Whisper Large is $0.218/hour. See deepgram.com/pricing for current rates.
What is Deepgram Nova-3?
Nova-3 is Deepgram's latest speech recognition model, offering high accuracy with approximately 300 ms P50 latency for real-time streaming. It supports 30+ languages and is optimised for conversational and call-centre audio.
Does Deepgram support real-time transcription?
Yes. Deepgram's streaming API delivers transcription results with ~300 ms latency, making it suitable for live captions, voice agents, and real-time call analytics.
