Gen-4.5 model profile
Evidence snapshot:
Gen-4.5 is a Runway model profile with a no verified token context limit in this snapshot. The dated catalog snapshot records text, image, video modalities and interfaces for video generation, vision.
Runway Gen-4.5 is a video generation model from Runway for text-to-video and image-to-video workflows. It is designed for cinematic scene creation with strong motion quality, visual fidelity, and prompt adherence....
Gen-4.5 is a reference profile: Runway publishes it, Kendr documents it for comparison, and it carries no Kendr alias to call.
Gen-4.5 is an independent knowledge profile. It does not claim that Kendr hosts the model, quote a Kendr customer price, promise API availability, or advertise a Kendr routing receipt.
Gen-4.5 accepts text and image and returns video. The snapshot records video generation and vision as capabilities or interfaces.
The dated unit-price records list $0.12 per second for video_output (cents_per_second_output). Each figure retains its billable dimension, variant, provider, source, and evidence date.
No comparable third-party benchmark value is present in the 2026-09-06 snapshot. Missing values are not estimated.
No comparable popularity rank or traffic share is present in the 2026-09-06 snapshot. No comparable routing rank or traffic-share observation is attached to this dated profile; missing adoption evidence is not estimated.
Profile data was reviewed for the 2026-09-06 snapshot. Claims retain their source dates, and unavailable fields are shown as unavailable instead of estimated.

When to pick Gen-4.5
Gen-4.5 is a reference profile: Runway publishes it, Kendr documents it for comparison, and it carries no Kendr alias to call.
Each condition below is derived from this model's own values in the 2026-09-06 snapshot, compared only against models publishing the same field.
- Reach for it when the input includes images. The snapshot records image input, so screenshots, scans, and diagrams can be sent directly instead of described.
- Reach for it when the output is video. This route produces video rather than only text, and those units are priced separately from tokens.
- Look elsewhere when you need to call it through Kendr today. This is a research reference profile with no Kendr alias. The facts and evidence here are published for comparison; the model is not routable on Kendr.
- Look elsewhere when you are building an agent. No tool-calling capability is recorded for this model in the snapshot. Agent loops need a route that can call functions.

Look elsewhere when you are building an agent: No tool-calling capability is recorded for this model in the snapshot. Agent loops need a route that can call functions.
What is Gen-4.5?
Gen-4.5 is a Runway model profile with a no verified token context limit in this snapshot. The dated catalog snapshot records text, image, video modalities and interfaces for video generation, vision.
Does Gen-4.5 have a verified token context window?
No comparable token context window is present in this dated profile. The page reports text and image inputs, video outputs, and source-backed modality limits instead of inventing a token limit.
What benchmark evidence is available for Gen-4.5?
No comparable third-party benchmark value is present in the 2026-09-06 snapshot. Missing values are not estimated. Third-party catalog fields normalized from the cited model dataset; benchmark methodology and coverage differ by source.
Is Gen-4.5 available through Kendr?
This is an independent knowledge profile, not a Kendr-hosted availability claim. Check Kendr's live public model API for currently enabled Kendr aliases.
Does the popularity rank represent Gen-4.5's global market share?
No comparable popularity rank or traffic share is present in the 2026-09-06 snapshot. No comparable routing rank or traffic-share observation is attached to this dated profile; missing adoption evidence is not estimated. No global market-share percentage is inferred when the source does not publish one.
