Crun AI's visual, node-based canvas for building custom AI content-generation workflows — chain image, video, and audio models from its 100+ model catalog on one endless workspace.

Crun AI (crun.ai) is a unified AI media API: one OpenAI-compatible endpoint that reaches 100-plus image, video, and audio models from many providers, so you integrate once instead of maintaining a separate SDK and billing relationship for each. The catalog spans video (models in the Veo, Sora, Kling, Seedance, Wan, Vidu, and Runway families), image (Nano Banana, Flux, Seedream, GPT Image, Imagen, Qwen Image, Midjourney), and audio (Suno-style music, TTS), billed pay-as-you-go on a points/credit system with no mandatory subscription. Confirm the live model list and per-model rates on crun.ai, since both move constantly.
The Infinite Canvas is Crun's visual layer on top of that API. Instead of writing code to call each model, you work on an endless canvas where each model is a node: you connect a prompt to an image model, feed that image into a video model, pass the clip to an audio or voice model, and lay out variations and iterations side by side in one boundless workspace. The point is to turn "juggle a dozen model APIs" into "chain them visually into a repeatable content-generation workflow" — the same node-graph pattern other canvas tools use, but riding Crun's single unified model catalog underneath.
That combination is genuinely useful for experimentation: you can compare Seedance against Kling on the same prompt, prototype a text-to-image-to-video pipeline without integration work, and reuse a workflow once it's dialed in. Because Crun bills per generation rather than per seat, the cost tracks what you actually render.
The honest boundary: the canvas gets you a raw asset — a clip, an image, an audio track, or a small pipeline that outputs one. It does not write in your brand voice, hold a persona's identity across pieces, reframe an asset per feed, caption it, schedule it, or publish it anywhere. Turning a canvas output into finished, distributed content is a separate job.
The Infinite Canvas is a generation studio: its output is a raw asset sitting on a canvas — a 6-second Seedance clip, a Flux still, a Suno track. A raw asset is not a captioned vertical short, a brand-exact carousel, or a scheduled week of posts, and that gap is exactly where [Kompozy](/) picks up. Bring a finished canvas render in as a source and Kompozy does the distribution work the canvas doesn't: it [clips](/glossary/clipped-short) a longer render into eight to ten vertical cuts and auto-reframes each to 9:16, 1:1, and 16:9 with burned-in captions; lifts a still into a brand-exact [Carousel](/glossary/hyperframes) or [Quote Graphic](/glossary/output-buckets); and drafts the blog and newsletter around it — every piece written in one voice through your [Persona Brief](/glossary/persona-brief) and pushed across the eight social platforms plus blog and email from a single queue, on a review gate or [Autopilot](/glossary/autopilot).
The pairing is clean because the two tools own different halves of the job. Crun's canvas is where you experiment and render; Kompozy is where a render becomes on-brand content that actually ships — and it also generates the formats a model canvas can't assemble on its own: [Persona Shorts](/glossary/persona-shorts) and [Persona Frames](/glossary/persona-frames) talking-head video from a script with a face-locked avatar, VFX hooks, and infographics. Use the canvas to find the shot; use Kompozy to turn one shot into a month of posts.
It is Crun AI's visual, node-based workspace for building custom content-generation workflows. Each AI model is a node you connect on an endless canvas — chaining, for example, a prompt to an image model to a video model — so you can orchestrate Crun's 100+ image, video, and audio models without writing integration code.

Crun is a unified API that reaches 100-plus image, video, and audio models from many providers — video families like Veo, Sora, Kling, Seedance, Wan, Vidu, and Runway, image models like Nano Banana, Flux, Seedream, GPT Image, Imagen, Qwen Image, and Midjourney, plus music and TTS. The live catalog changes, so check crun.ai for what is currently available.
Crun bills pay-as-you-go on a points/credit system with no mandatory subscription — you pay per generation, and the cost varies by model. It offers a free trial. Because rates move with the underlying providers, confirm current per-model pricing on crun.ai.
No. Crun's canvas generates raw assets — clips, images, and audio — and stops there. It has no brand-voice layer, captioning, per-platform reframing, or scheduler. To turn a canvas render into on-brand posts and publish across platforms, you pair it with a content engine like Kompozy.
Crun is a generation and orchestration layer — a model API with a visual canvas for building workflows. Kompozy is the application layer that turns a finished asset into 18 published formats across nine destinations, governed by a Persona Brief, and generates net-new persona/avatar video the canvas can't assemble. Many creators use both: render on Crun, distribute with Kompozy.
