Why Use Runway Aleph Through RunAPI

One auth, every provider

A single RunAPI API key unlocks the whole model catalog across all providers. No separate accounts to create, no API keys to rotate per integration, and no credential management overhead. Add a new model to your app by changing one parameter.

Unified pricing & billing

Per-call pricing in USD, billed monthly into a single invoice. No subscription tiers, no minimum spend, and failed generations are never charged. The pricing page and check_pricing API show exact costs before you commit to a model.

Schema-first SDK

Typed schemas, parameter constraints, and setup notes are packaged in the model skill so your implementation starts from the right contract. The skill loads into Claude Code, Codex, Gemini CLI, Cursor, and VS Code — your agent knows the correct request shape before you write a line of code.

Runway Aleph Questions

What is prompt-guided video editing?

Runway Aleph takes existing footage and retransforms its visual style or content based on a text prompt, while preserving the original motion and camera dynamics.

Does it preserve the original motion?

Yes — Aleph maintains frame-level temporal continuity, keeping camera movement, subject motion, and timing intact while changing visual style.

What styles can I apply?

Any style describable in text — watercolor, oil painting, anime, cyberpunk, vintage film, and more. The model interprets the style prompt creatively.

What input video formats are supported?

MP4 is the primary supported format. Keep source clips under the size and duration limits in the API docs for best results.

How does Aleph differ from standard Runway?

Standard Runway generates video from text or images. Aleph specifically transforms existing footage, making it an editing tool rather than a generator.

Which variant should I start with?

Pick the cheapest variant that meets your quality bar. Most teams start on the fast variant and graduate to pro for production.
