--- title: "Gen-4.5 AI model: facts and benchmarks | Kendr" canonical: "https://kendr.org/models/runway-gen-4-5" date_modified: "2026-08-12" profile_kind: "reference" --- # Gen-4.5 model profile 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. 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 2026-08-12 snapshot. Missing values are not estimated. No comparable popularity rank or traffic share is present in the 2026-08-12 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 2026-08-12 snapshot. Claims retain their source dates, and unavailable fields are shown as unavailable instead of estimated. ## Profile facts - **Profile type:** Model research profile - **Provider or publisher:** Runway - **Context window:** No verified limit - **Snapshot date:** 2026-08-12 - **Reference catalog ID:** runway/gen-4.5 ## Context, modalities, and identity Gen-4.5 accepts text and image and returns video. The snapshot records video generation and vision as capabilities or interfaces. - **Provider or publisher:** Runway - **Context window:** No verified limit - **Maximum output:** No verified numeric limit - **Input modalities:** text and image - **Output modalities:** video - **Knowledge cutoff:** Not disclosed ## Capabilities and supported controls Capabilities and parameters are reported from the dated catalog and source records; their presence does not guarantee identical behavior across every provider route. - **Supported parameters:** No verified parameter list - video generation - vision ## Dated pricing snapshot 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. These are dated third-party reference prices, not Kendr prices or an availability offer. Routes, tiers, caching, region, and provider policy can change the landed price. - **Price date:** 2026-08-12 - **Input:** No verified rate - **Cached input:** No verified rate - **Output:** No verified rate | Billable | Variant | Cost | Unit | Provider | As of | | --- | --- | --- | --- | --- | --- | | video_output | cents_per_second_output | $0.12 | per second | Not specified | 2026-08-12 | ## Benchmark evidence and limitations No comparable third-party benchmark value is present in the 2026-08-12 snapshot. Missing values are not estimated. Third-party catalog fields normalized from the cited model dataset; benchmark methodology and coverage differ by source. ## Popularity and market context No comparable popularity rank or traffic share is present in the 2026-08-12 snapshot. No comparable routing rank or traffic-share observation is attached to this dated profile; missing adoption evidence is not estimated. - **Third-party catalog rank:** No verified rank - **Global market share:** Not inferred - **Observation date:** 2026-08-12 ## Frequently asked questions ### 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 2026-08-12 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 2026-08-12 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. ## Sources and evidence dates - [Gen-4.5 third-party catalog record](https://openrouter.ai/runway/gen-4.5) — catalog, checked 2026-08-12 - [Third-party model catalog methodology](https://openrouter.ai/docs/guides/overview/models) — methodology, checked 2026-08-12 - [Runway official model documentation](https://docs.dev.runwayml.com/) — primary, checked 2026-08-12 - [Gen-4.5 third-party catalog record](https://openrouter.ai/runway/gen-4.5) — catalog, checked 2026-08-12 Live Kendr operational availability is published separately at https://api.kendr.org/api/public/models.
