Runway Gen-4.5 API pricing
Gen-4.5 720p text-to-video price
- Reviewed comparison scope
- Runway Gen-4.5 · text to video · 720p · no audio · global route · USD per generated output second
- Publication gate
- At least 3 unique providers with accepted, fresh, reviewed evidence
Why there is no winner
Ranking withheld: 2 of 3 required providers have fresh, matching evidence.
Runway developer credits are normalized at $0.01 per credit. Web-app subscription credits, Gen-4, Gen-4 Turbo, image-to-video inputs, and third-party models sold inside Runway are outside this result.

Decision guide
How to compare Runway Gen-4.5 API providers
Runway Gen-4.5 is an exact video model, not a label for every model sold through Runway. The owner developer API identifies the route as gen4.5 and prices it in developer credits per generated second. Replicate exposes runwayml/gen-4.5 as a separate purchasing channel. APIDir maps both routes to the same exact model while retaining their different provider identities and source pages.
The current comparison fixes text-to-video, 720p output, no native audio, a global public route, and a per-output-second meter. Both channels publish twelve cents per generated second. Two matching routes are useful evidence, but APIDir requires three unique providers before assigning a rank or cheapest label, so the page shows a comparison table and an explicit no-winner state.
The page excludes Runway web subscriptions, Explore Mode, Gen-4, Gen-4 Turbo, Aleph, and third-party models offered inside the Runway product. Those options may serve a similar creative job, but they are not Gen-4.5 API price evidence. Operational testing should still compare queue behavior, moderation, limits, retention, support, and usable-output rate.
What changes Runway Gen-4.5 API cost
- Generated output seconds, requested duration, and the number of accepted creative reruns
- Exact Gen-4.5 route versus Gen-4 Turbo or another model with a similar family name
- Developer API credit economics versus unrelated web subscription or promotional credit bundles
- Moderation failures, unknown submission outcomes, storage, egress, post-processing, and human review
Integration checks before production
- Pin gen4.5 or runwayml/gen-4.5 and reject a generic Runway model alias
- Validate supported duration, aspect ratio, mode, and asset inputs before a billable submission
- Use idempotency where the provider supports it and bounded backoff for status reads
- Log provider route, request ID, terminal status, output seconds, retries, and charged credits without storing secrets
Workloads this comparison can inform
Automated campaign clips
Estimate successful output seconds and an observed creative rerun rate, then compare delivery time and usable-output rate beside the common twelve-cent meter.
Provider continuity
A second purchase channel can reduce account concentration, but request schemas, error semantics, moderation, and retention need a controlled compatibility test.
Manual and programmatic workflows
Keep creator-seat subscription spend separate from API automation. A plan that works for manual exploration does not establish the developer API cost.
How to read the price result
The two accepted channels currently publish the same Gen-4.5 output-second rate. APIDir shows both sources and configurations but does not manufacture a #1 below the three-provider rule.

Use this evidence safely
A recorded price is not a complete production quote. Open the source, reproduce the exact configuration, and include retries, failed work, storage, egress, support, rate limits, and downstream processing in total cost.
Questions developers ask
What makes two Runway offers comparable?
The model version, generation mode, tier, resolution, duration, audio setting, region, and billing unit must match.
Does APIDir name a cheapest provider on this page?
Only when at least three explicitly reviewed provider offers are fresh, publication-permitted, and within the same published comparison scope. Stale or mismatched evidence cannot support that claim.
How should I confirm a budget?
Open the linked provider source, verify the configuration, then calculate your own successful and failed workload volume.
