Stable Diffusion
Pros
- + Weights are downloadable and self-hostable: my batch jobs ran with data staying on my own hardware
- + API billing is flat and transparent — 3 credits (US$0.03) per Stable Image Core image matched my 100-image batch total exactly
- + Largest extension ecosystem in the category: LoRAs, ControlNets, IP-Adapter, regional prompting via ComfyUI
- + Community License is free for research and commercial use under US$1M annual revenue
- + 150 requests per 10 seconds on the API and no charge for filter-blocked outputs
Cons
- - Out-of-the-box aesthetics trail Midjourney and FLUX; defaults need prompt craft or fine-tuning to compete
- - Community License is not plain open source: US$1M revenue cap, registration requirement, auto-termination above it
- - SD 3.5 Large (8B) needs serious GPU hardware; on a 24 GB card my iteration speed was slow versus Turbo or Medium
- - Tooling is fragmented across ComfyUI, Automatic1111 and forks — a real learning curve and maintenance burden
- - Stability AI's management turbulence and the new 12-month credit expiry (from Sep 30, 2026) are caution flags for long-term bets
Adobe Firefly
Pros
- + Standard image features (Generative Fill, moodboards) are unmetered on paid plans — my credit counter barely moved during image-only sessions
- + Only generator I tested that produces editable vector output via the Firefly Vector Model in Illustrator
- + Content Credentials metadata and the Do Not Train tag attach to outputs, which is the provenance story enterprise buyers ask for
- + Partner models from Google, OpenAI, Flux and Kling sit inside the same credit wallet as Adobe's own models
- + Generative Extend in Premiere Pro filled a short interview clip tail in one pass in my testing
Cons
- - Video work burns credits fast: 2,000 credits is only about 20 five-second clips per Adobe's own plan table
- - Credits never roll over between billing cycles
- - Aesthetic ceiling on photoreal and stylized images trails Midjourney on hard prompts
- - Top unlimited Firefly Video Model access sits at US$199.99/month, far above the entry tier
- - Requires an Adobe account and works best when you already pay for Creative Cloud
