Runware
Runware is a developer API for generating images and video across many open and commercial models. Its Sonic Inference Engine is a custom hardware-and-software stack tuned for inference, which it uses to undercut typical cloud GPU costs - image generation from about $0.0006 each, billed per request with no commitment. One API covers FLUX, Qwen, Seedream and more.

Our take
Runware competes on price and speed: a custom inference stack that runs image and video models for a fraction of typical cloud-GPU cost - images from about $0.0006, pay-per-request, no commit. For developers building generative features at scale, the economics are hard to argue with. It's infrastructure, not an end-user app, but the $50M Series A signals real traction.
Best for
Developers and product teams embedding image or video generation at scale who want one API across many models and the lowest possible per-output cost.
Pros
- Image generation from about $0.0006, among the cheapest available
- One API across FLUX, Qwen, Seedream and more
- Pay-per-request, no subscription or commitment
- Custom Sonic Inference Engine tuned for speed
Cons
- Developer infrastructure, not a no-code app
- Speed and cost claims are vendor-benchmarked
- You manage prompts and orchestration yourself
How it compares
Runware sits alongside fal and Replicate as a 'one API for all AI' media platform. Its edge is cost - a custom inference stack rather than reselling GPUs - where fal leads on breadth of models and Replicate on community and ease.

Nano Banana Pro
Nano Banana Pro is Google's flagship image generation and editing model, built on the Gemini 3 Pro architecture. It is known for accurate text rendering inside images, keeping a subject's identity consistent across edits, and a reasoning-first approach that follows complex prompts and infographic-style layouts. You can use it through the Gemini app and Google's API; it succeeds the original Nano Banana, with a faster Nano Banana 2 following in 2026.
Seedream
Seedream is ByteDance's frontier image model family, combining generation and editing in one architecture. Recent versions (4.x and 5) produce 2K images in under two seconds, scale to 4K, and handle reference-driven generation - attach images to keep a character, style or composition consistent across outputs. It is known for sharp text rendering inside images. You can use it via ByteDance's Dreamina app, fal, Replicate and Recraft Studio.
