Pricing	Pay per token — model-dependent	Free (limited) + $10/mo Pro + $19/mo Business	Pay per second of compute	Free + included with Creative Cloud
Best for	Developers experimenting across models. Apps that want fallback logic.	Teams with GitHub already. Devs who don't want to change IDEs.	Developers using open-source models (Flux, SDXL, Whisper, etc).	Anyone in Creative Cloud. Brands that need copyright clarity.
Strengths	300+ models from one endpoint Automatic fallbacks between providers No subscription — just pay what you use	Great enterprise story Works in your existing IDE Chat + autocomplete	Tens of thousands of models (image, video, audio, LLMs) One-line API for any model Cog framework for custom model deploy	Trained on licensed content — commercially safe Generative Fill in Photoshop is incredible Native to Adobe ecosystem
Weaknesses	Slight markup over direct API Some provider features not exposed	Less agentic than Cursor/Claude Code Model quality varies	Cold starts on less-popular models Pricing gets real at scale	Aesthetic ceiling below Midjourney Tied to Adobe subscription
Kai's verdict	S-tier for model-shopping. I use this for every prototype before committing.	B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.	S-tier for open-source model APIs. The default in this space.	S-tier inside Photoshop (Generative Fill). B-tier standalone.
