Runway Gen

Overview

Runway Gen-4.5 is the flagship video model sold by Runway, as distinct from the other companies' models that Runway's API also prices in the same credit. This page is about Gen-4.5. The product, the plan cards, and the editor are /tools/runway. Kling, Seedance, Veo, Wan, and Hailuo rows on the Runway price guide are not Gen. Follow those models to /models/kling, /models/seedance, /models/veo, and /models/minimax-hailuo.

Status on 2026-10-16: Gen-4.5 is on the public consumer pricing page and on the developer pricing guide. That is general availability for people who can buy the listed plans or API credits. A waitlist was not on either page. A country block list was not on either page. Enterprise language on the consumer page says enterprises get two months of usage free if they sign by 10/31. That date is a sales window on the page, not a model sunset.

Filter booleans are conservative where the card is silent. t2v is true because both surfaces sell Gen-4.5 as seconds of generated video, and the consumer page accounts for "seconds of Gen-4.5" inside a plan. i2v is false in the filter because the API guide bills gen4.5 as one line, 12 credits per second, and does not publish a text-to-video row next to an image-to-video row. Image-to-video may exist in the product. It was not a mode on the price card, so the boolean does not assert it. native_audio is false. Models that have an audio split on that same guide, including veo3.1 and kling3.0_pro, are written as two lines. Gen-4.5 is one line. A native-audio switch for Gen-4.5 was not observed. multi_shot is false. A multi-shot field for Gen-4.5 was not on the guide. Runway does sell a multi_shot_video recipe at a different credit rate. That recipe is not labeled Gen-4.5 in the cell that was read. open_source is false.

Specs

Version line. Gen-4.5 is the model this page prices. Gen-4 Turbo is a cheaper credit line on the same guide, 5 credits per second, and the consumer page also counts "seconds of Gen-4 Turbo." Gen-4 image is a still model (gen4_image, 5 credits per 720p image or 8 credits per 1080p image). Aleph 2.0 shares the professional-output surcharge table with Gen-4.5 and is not Gen-4.5. Act Two is 5 credits per second and is not given a Gen-4.5 alias here.

What the API guide states for Gen-4.5:

Field	Observed value
Price	12 credits per second.
Credit cash price	$0.01 per credit, so 12 credits is $0.12 per second derived.
Professional formats	prores and png_sequence add 5 credits per second on Gen-4.5 and Aleph 2.0.
HDR and 10-bit profiles	20 credits per second, or 40 credits per second when the output is larger than 4 megapixels (roughly 4K). Profiles named: hdr10, hlg, sdr_rec709_10bit, hdr_pq_12bit_master, hdr_prores, hdr_png_sequence, hdr_exr_sequence, hdr_exr_acescg_sequence_1_3, hdr_exr_acescg_sequence_2_0.

Duration enum, aspect enum, frame rate, maximum prompt length, and a reference-image cap for Gen-4.5 were not on the pricing guide. They are not observed. The consumer page expresses plans as seconds of Gen-4.5, which confirms a per-second meter and does not reveal the maximum seconds per request.

Consumer credit examples on runwayml.com/pricing, which redirected to runway.com/pricing on 2026-10-16: Gen-4.5 is 60 credits per 5 seconds, which is 12 credits per second and matches the API line. On the same compare table, Aleph 2.0 is 140 credits per 5 seconds, Seedance 2.0 Pro at 1080p is 160 credits per 4 seconds, and Seedance 2.0 Fast is 116 credits per 4 seconds. Those three rows are not Gen-4.5. Do not average them into the 12-credit rate.

A calculator embedded in the API guide uses 'gen4.5': 12, which agrees with the table.

Prompt notes

No Gen-4.5 prompt was published as a worked example in the pricing extracts, and none was run here. The practical note is about the meter. A longer prompt does not show a token price. You pay credits per second of output, plus a format surcharge if you ask for ProRes, a PNG sequence, or an HDR profile. Asking for "4K HDR" without reading the surcharge is how a 12-credit estimate becomes 12 plus 40. The guide says the 40-credit HDR rate applies when the output is larger than 4 megapixels. Whether every Gen-4.5 render can reach that size was not stated as a resolution enum.

Arena scores for Gen-4.5 were not opened. Not observed.

Where to run

1. Runway's consumer pricing page: runwayml.com/pricing. Plans, included seconds, and the Gen-4.5 credit examples. The app checkout links point at app.runwayml.com.
2. Runway's developer pricing guide: docs.dev.runwayml.com/guides/pricing. The gen4.5 row, the $0.01 credit price, and the professional-output surcharges.
3. The product write-up in this directory: /tools/runway.

A second company must appear because a selection page should not trap the reader inside one vendor. Gen-4.5 itself was not found as a resale row on fal, on BytePlus, or on the Higgsfield catalog index saved the same day. For Gen-4.5, the two Runway surfaces are the channels, and they are different wallets: plan credits versus API credits purchased at $0.01. That is "official only" across two Runway doors, not two unrelated hosts. If a workflow can change models, the other doors on the same API guide are the escape hatch, and they are different models.

Luma's pricing page did not show a Gen-4.5 credit row in the portion read. Not observed there.

Multi-channel pricing

Verified 2026-10-16 on both Runway pages. There is no non-Runway dollar card for Gen-4.5 in this pass. The two channels are the API meter and the consumer plan.

API. $0.01 per credit. Sales tax may apply. gen4.5 is 12 credits per second. Derived base price $0.12 per second. Add 5 credits per second for prores or png_sequence. Add 20 credits per second for the named 10-bit and HDR profiles, or 40 credits per second when output is larger than roughly 4K. A 5-second base clip is 60 credits, $0.60 derived, which matches the consumer page's "60 credits/5s" Gen-4.5 row. The "140 credits/5s" row on that table is Aleph 2.0, not a second Gen-4.5 rate. A 5-second clip with the 40-credit HDR adder would be (12+40) times 5 = 260 credits, $2.60 derived. That stack is arithmetic from the guide, not a SKU name Runway printed.

Consumer plans, from the pricing page text. Free: $0 per month, 125 one-time credits. Standard: $15 per month, or $12 per month billed annually (save $36 a year), 625 credits monthly. The page equates 625 credits to 52 seconds of Gen-4.5, 104 seconds of Gen-4 Turbo, or 78 Gen-4 images at 1080p. Pro, labeled Pro on the card: $35 per month, or $28 per month billed annually (save $84 a year), 2250 credits monthly, equated to 187 seconds of Gen-4.5, 375 seconds of Gen-4 Turbo, or 281 Gen-4 images at 1080p. The Pro card also lists top-up credits, unlimited 4K upscaling, and a bullet whose visible text is "Unlimited" followed by chips for Seedance 2.5, Gen-4.5, Kling 3.0, Nano Banana Pro, and more. Max: $95 per month, or $76 per month billed annually (save $228 a year), 9500 credits, equated to 791 seconds of Gen-4.5, 791 seconds of Gen-4, 1900 seconds of Gen-4 Turbo, 1187 Gen-4 images at 1080p, or 475 Nano Banana Pro images at 2K. Max rolls unused credits for one month. The page says unlimited Wan 3.0 and Wan 3.0 Prime in Tool Mode until October 18. Yearly credit totals printed nearby: $12 per month maps to 7,500 credits a year, $28 per month to 27,000, and $76 per month to 114,000.

Check the arithmetic the page invites. 625 credits divided by 12 credits per second is about 52.1 seconds, which matches the "52s of Gen-4.5" line. 2250 / 12 is 187.5, matching 187 seconds. 9500 / 12 is about 791.7, matching 791 seconds. Those plan equivalences use the 12-credit Gen-4.5 rate. The 140-credit row is Aleph 2.0. The FAQ on the page says Standard and Pro monthly credits do not roll over, and that extra credits can be bought with a 1,000 credit minimum. Upgrade is immediate and prorated, per that FAQ.

The Pro "Unlimited" chip row names Seedance 2.5, Gen-4.5, Kling 3.0, and Nano Banana Pro together. The page does not define a fair-use cap in the extracted lines. The same Pro card still equates 2250 credits to 187 seconds of Gen-4.5, so the chip row and the seconds line disagree. Seedance's own API credit price is on the Seedance model page.

Workflow and platform fit

Site workflow labels only. No workflow guide URLs are linked, because those guides are not published as real pages.

Faceless. A plan that buys seconds of Gen-4.5 can supply B-roll, but native audio was not on the Gen-4.5 price line. Budget a voice. /tools/elevenlabs is the voice product in this directory. Captions and a cover are /tools/capcut. A 52-second Standard monthly pool is one short faceless test, not a posting cadence. Pro's 187 seconds is still a handful of cuts if you iterate.

UGC ads. Runway's API guide prices recipes that are not Gen-4.5: product_ad, product_swap, and product_ugc, each with a 4-second minimum and a 15-second maximum, at a few hundred credits for the first 4 seconds plus a per-extra-second rate. Read those recipes on the guide before you assume a UGC job bills at 12 credits per second. /tools/creatify is the template path when you do not want to assemble the recipe yourself. Image-to-video for Gen-4.5 specifically remains not observed as a separate row.

AI avatar. Gen-4.5's card does not describe a photo avatar or a voice clone as part of the model meter. The consumer Pro plan mentions one custom voice clone as a plan feature. That is a product entitlement, not a Gen-4.5 spec. Presenters belong on /models/heygen-video.

Long-to-short. Nothing on the Gen-4.5 line ingests a long recording. Use an editor to cut, then generate replacement B-roll by the second.

Captions and cover. Gen-4 image can make a still at 5 or 8 credits. It is not an auto-caption model. Captions stay in CapCut or a caption tool. Not observed inside Gen-4.5.

Voice and publish. Because native audio is not on the price split, publish flow is picture first and sound second. Vertical aspect support for Gen-4.5 was not on the price guide. Shorts fitness is therefore "possible if the product UI offers 9:16," and that UI control was not copied into the pricing extract. Do not claim 9:16 as a verified enum. HDR and ProRes matter for a grade and are usually stripped or recompressed before a Shorts upload. The surcharge is a master cost, not a phone-preview cost.

Shorts vertical fit. Economical at the derived $0.12 per second base if the unobserved aspect control exists in the app you use, and incomplete as a one-stop Shorts tool because audio, captions, and a confirmed 9:16 enum were not on the card. Compare Kling or Seedance when the vertical enum and the audio flag have to be in the schema you cite.

Pros

• The API rate is a single number, 12 credits per second, and the consumer "seconds of Gen-4.5" lines divide cleanly by that number. Two Runway pages agree on the base meter.
• The $0.01 credit price makes the derived dollar predictable, before tax and before surcharges.
• Professional and HDR outputs are priced as adders with named format strings, which is the right shape for a finishing pipeline.
• Plan equivalences are printed in seconds, so a buyer can see that Standard's 625 credits are 52 seconds of this model and not a vague "credit pack."
• The same guide prices other models, which makes a controlled comparison inside one wallet possible. Those other models still need their own pages, because a credit is not a quality claim.

Cons

• The consumer compare table prints 140 credits per 5 seconds on the Aleph 2.0 row, next to Gen-4.5 at 60 credits per 5 seconds. Quote the model name with the row. There is not a second unmapped Gen-4.5 rate on that table.
• Duration, resolution, and aspect for a default Gen-4.5 request were not on the pricing guide. The spec table is thinner than Veo's or Seedance's.
• Image-to-video is not a separate price line. The filter refuses to call it true.
• Native audio is not a price split. A talking clip needs another tool or a model whose card itemizes audio.
• Gen-4.5 was not observed on a non-Runway host. You cannot arbitrage this model across fal and Runway the way you can arbitrage Kling.
• The Pro "Unlimited" chips include Gen-4.5 by name, next to Seedance 2.5. The Gen-4.5 meter on that same card is still 187 seconds at 2250 credits. Read both lines before you treat Gen-4.5 as unlimited.

Alternatives

• Kling on the same Runway guide is 9 to 43 credits per second depending on standard, pro, audio, and 4K. Kling's own site also prints unit prices. Choose Kling when you need a documented audio toggle and a 9:16 fal enum.
• Seedance on Runway is 20, 30, or 68 credits per output second by resolution, higher than Gen-4.5's base 12, with a longer duration enum on fal. The Pro plan's unlimited Seedance line, if it applies to your account, changes that comparison inside the app only.
• Veo on Runway is 20 or 40 credits per second for standard silent versus audio, above Gen-4.5's base rate, with a Google GA card elsewhere.
• Luma Ray is the HDR and EXR specialist with its own dollar API. Gen-4.5's HDR path is a credit surcharge on Runway, not an EXR-first product page.
• MiniMax Hailuo is the lower official list price per second when you do not need Runway's format menu.

Related tools

• /tools/runway is the product that contains Gen-4.5, the plans, and the other hosted models.
• /tools/capcut finishes captions, covers, and vertical reframes after export.
• /tools/elevenlabs supplies voice because Gen-4.5's price line has no audio split.
• /tools/creatify is the UGC-template alternative when the Runway product recipes are more structure than you want to bill by hand.
• /tools/heygen is the avatar product, not a Gen-4.5 mode.
• /tools/kling, /tools/seedance, and /tools/higgsfield are the neighboring studios. Higgsfield was not observed reselling Gen-4.5 in the catalog snapshot.

FAQ

Is Gen-4.5 the same as every model inside Runway?

No. Gen-4.5 is one row. Kling, Veo, Seedance, Wan, and Hailuo have their own rows on the same guide. The app can hide that distinction behind a single credit balance.

How much is one second?

Twelve credits on the API table. At the printed $0.01 per credit, that is $0.12 before tax and before ProRes or HDR adders. The consumer compare table's 140 credits per 5 seconds row is Aleph 2.0. Do not average it with the Gen-4.5 rate of 12 credits per second.

Does it include native audio?

Not observed as a Gen-4.5 price split. The guide does split audio for other model ids. This page sets native audio to false so the filter does not promise speech.

Can I start from an image?

Not observed as a distinct Gen-4.5 price line. The boolean for image-to-video is false for that reason. Some other Runway rows do mention an image-to-video start frame. They are not gen4.5.

Do monthly credits roll over?

The consumer FAQ says Standard and Pro monthly credits do not roll over. Max can roll unused credits for one month. API credits bought at $0.01 are a different wallet. Their expiry was not in the sentences extracted here.
