Tagline	OpenAI's image model. Built into ChatGPT Plus.	One API, every model. Pay-as-you-go, no subscriptions.	Stability AI's open audio model. Loops + SFX + background.	Run any open-source AI model with an API call.
Category	Image	Dev Platform	Audio	Dev Platform
Pricing	Included with ChatGPT Plus $20/mo	Pay per token — model-dependent	Free + $12/mo Pro + enterprise	Pay per second of compute
Best for	ChatGPT Plus users who want images without paying extra.	Developers experimenting across models. Apps that want fallback logic.	Game developers, podcasters needing SFX, video creators needing background music.	Developers using open-source models (Flux, SDXL, Whisper, etc).
Strengths	Excellent prompt understanding Built into ChatGPT — no extra subscription Good at composition + concepts	300+ models from one endpoint Automatic fallbacks between providers No subscription — just pay what you use	Open-weight model available Great for loops + game audio + SFX Commercial-use clarity	Tens of thousands of models (image, video, audio, LLMs) One-line API for any model Cog framework for custom model deploy
Weaknesses	Aesthetic ceiling below Midjourney + Ideogram Text rendering worse than Ideogram No fine control	Slight markup over direct API Some provider features not exposed	Not for full songs with vocals Shorter generation limits	Cold starts on less-popular models Pricing gets real at scale
Kai's verdict	B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.	S-tier for model-shopping. I use this for every prototype before committing.	A-tier for its niche. Different use case than Suno — SFX and loops, not songs.	S-tier for open-source model APIs. The default in this space.
