Veo 3.1 Fast starts at 16 credits
Veo 3.1 Fast starts at 16 credits: 4s audio-off at 4/s discounted. Lite is also 16. Parent Veo 3.1 starts at 64. Same 4/6/8s family, three Versely rows.
Veo 3.1 Fast starts at 16 credits. That is the 4-second, audio-off floor on Versely, as of the 19 September 2026 catalog, with the live 50 percent discount on. Lite starts at the same 16. Parent Veo 3.1 starts at 64. Same Google family. Same 4 / 6 / 8 second lengths. Three different meters. This page is those three rows. It is not a "best Veo 2026" ranking, and it is not a Flow review.
Google DeepMind's Veo page. On Versely the 3.1 family is three catalog rows with three bills, not one marketing surface.
Fast and Lite do not have published model pages. The numbers below are from the Versely catalog on 19 September 2026. Do not bookmark a Fast or Lite URL you invented. The published row is Veo 3.1. The generate door is the AI video generator. If the brief is not a Veo-shaped 4 / 6 / 8 second clip, Model Finder is the filter, not a prompt rewrite.
Three rows, one 4 / 6 / 8 family
Google's Veo 3.1 line on Versely is not one card with a speed toggle. It is three catalog objects. They share durations (4s, 6s, 8s), a 4K output ceiling, 16:9 / 9:16 / auto, and an audio-based per-second bill. They do not share the floor, the ceiling, the discount, the category list, or the frame-rate list. Treat the name "Veo 3.1" as a family. Treat the row as the SKU.
Veo 3.1 Fast. Catalog slug veo-3-1-fast. Display name VEO 3.1 Fast. Description: fast variant of VEO 3.1 for quick video generation.

Those three paragraphs are the whole family this page covers. Reference-to-video, first-last-frame, and extend are other Veo jobs with other published slugs. Older VEO 3 Fast (google-veo-3-fast) is a different generation, a different sticker, a 1080p ceiling. Do not mix it into this 3.1 arithmetic. This page does not rank the three rows by "look." It bills them.
The 4-second silent floor is 16, 16, and 64
The formula is the same on all three: credits = rate_per_second(audio on | audio off) × seconds. Seconds are 4, 6, or 8. There is no 5, no 7, no 10. A 5-second idea buys 6. An 8-second idea is the top step, not a trim of a longer take. Trimming after the fact does not refund the seconds you generated.
Audio off, using the live discounted Fast rates and the undiscounted Lite and parent rates:
| Duration | Fast (4/s disc.) | Lite (4/s) | Veo 3.1 (16/s) |
|---|---|---|---|
| 4s | 16 | 16 | 64 |
| 6s | 24 | 24 | 96 |
| 8s | 32 | 32 | 128 |
The 4-second silent floor is the title of this page. Fast 16. Lite 16. Parent 64. Four Fast silent 4-second takes cost the same as one parent silent 4-second take. That is not a quality claim. It is the retry budget. If you are still finding the angle, spend the 16s. If you already know the angle and the brief is a text-to-video talking plate that needs the parent row, spend the 64 (or 128, or 256) on purpose.
Lite and Fast matching at 16 on the silent floor is the trap people remember as "they cost the same." They do, right now, silent. They do not share a discount. Fast's 16 is half of a 32-credit full floor (full_min_credits 32, display_original_price 32). Lite's 16 is the undiscounted floor (full_min_credits 16, display_original_price 16). If Fast's 50 percent off ends, Fast's silent 4-second take becomes 32 and Lite stays 16. Budget the sticker as a live quote, not as a permanent law that Fast is always the cheap twin.
Parent is four times the silent Fast/Lite floor at every duration in that table, because 16 per second is four times 4. 6 seconds silent is 24 vs 96. 8 seconds silent is 32 vs 128. The multiple does not hide in a surcharge. It is the rate.
Do not convert those credits to dollars on a Versely invoice. Credits are credits. The confirm screen is the bill. Recheck the live catalog the day you quote a client. Older posts in this archive still say Veo 3.1 is 40 credits. That number is stale against the 19 September 2026 parent row, which starts at 64.
Audio on is a second rate, not a checkbox
Native audio is not a line item you add after picture lock. On this family it replaces the per-second rate for the whole clip. Audio off and audio on are two cells. You pick one. You pay that cell times seconds.
Audio on, same catalog date:
| Duration | Fast (6/s disc.) | Lite (7/s) | Veo 3.1 (32/s) |
|---|---|---|---|
| 4s | 24 | 28 | 128 |
| 6s | 36 | 42 | 192 |
| 8s | 48 | 8 × 7 = 56 (listed max 52) | 256 |
Read the Fast column first. Discounted audio on is 6 credits a second. 4 seconds is 24. 6 seconds is 36. 8 seconds is 48. 48 is max_credits on Fast. The title's 16 is the cheap corner of the same matrix (4 seconds, audio off, discounted). The expensive corner is 8 seconds, audio on, discounted. Both numbers are Fast. People who remember "Fast is 16" and then turn audio on for an 8-second take are not being overcharged. They left the floor.
Full (undiscounted) Fast is 8 per second silent and 12 with audio: 32 to 96, which matches full_min_credits and full_max_credits. The 50 percent off is why the live span is 16 to 48. Quote the discounted cell while the flag is on. Quote the full cell if you are writing a budget that has to survive the discount dropping.
Lite's talking rate is 7 per second, not 6, and it is not discounted. A 4-second talking Lite take is 28, which is already 4 credits above Fast's discounted 24. A 6-second talking Lite take is 42. An 8-second talking Lite take at 7 per second is 56. The catalog lists max_credits 52. Those two integers do not agree. Do not invent a 52-credit 8-second talking SKU to paper over the gap, and do not bill 56 from a blog post. Read the quote on the generate screen for that job. 6 seconds talking (42) and 8 seconds silent (32) are clean products of the published rates. The 8-second talking Lite take is the one you confirm in the app.
Parent talking is 32 per second. 4 seconds is 128. 6 seconds is 192. 8 seconds is 256, which is max_credits. One parent 8-second talking take is 256. That is sixteen Fast silent 4-second takes at 16, or five Fast talking 8-second takes at 48 (240) with 16 credits left over. Use that comparison when the brief is "we need native dialogue on the hero" versus "we need twelve silent angles by lunch." Dialogue on the parent row is a rate switch, not a vibe.
Audio off is the largest saving on this family because it is a different rate, not a small add-on. If the destination is mute autoplay plus burned captions, generate silent and caption after. If the destination is a talking plate, turn audio on and pay the on rate. Do not write dialogue into a silent prompt and wait for a voice file. Do not turn audio on "to be safe" on a 4-second product orbit that will ship muted.
Fast's talking 8-second take is 48 credits
The useful Fast number is not only 16. It is the pair: 16 at 4 seconds silent, 48 at 8 seconds with audio on. Everything else on that row sits between them. 6 seconds silent is 24. 4 seconds talking is 24. 8 seconds silent is 32. 6 seconds talking is 36. If you cannot point at one of those six cells, you have not picked the job yet.
Pick Fast when the clip is a 4 / 6 / 8 second Veo-shaped take, you want the discounted meter, and you can live with 24fps or 30fps. Pick Lite when you want the undiscounted 16-credit silent floor (so a discount change does not move your unit cost), or when you need the dual text-to-video and image-to-video category list and you have checked the talking quote. Pick parent Veo 3.1 when the brief is the published T2V row: 60fps is on the list, the talking rate is 32 a second, and the floor is 64 because that is the model, not because Fast "failed."
Do not pick a row by rearranging the prompt until a cheap SKU looks like a dear one. Changing "cinematic, 8 seconds, dialogue" into a Fast 16-credit hope is how you get a 4-second silent clip you did not brief. Change the row, or change the brief. The AI video generator is the place the quote appears before you confirm. Model Finder is the place you filter when the job is not this family at all.
Flow is not this page. Flow is Google's launcher for Veo. If the question is "should I live in Flow," read Google Flow is a Veo surface, not a studio. Keep the model. Leave the surface if the slate is not only Veo. This page is only what the three Versely rows cost at 4, 6, and 8 seconds with audio on or off.
If you want a live quote on the family, create a Versely account and generate from the catalog, not from a remembered 16.
FAQ
Why does Fast start at 16 if Veo 3.1 starts at 64?
Because they are different rows with different per-second rates. Fast's discounted audio-off rate is 4 credits a second, so 4 seconds is 16. Parent Veo 3.1's audio-off rate is 16 credits a second, so 4 seconds is 64. Same durations. Same family name. Not the same SKU. Fast's 16 is also a 50 percent off number against a 32-credit full floor. Parent has no discount on that 64.
Do Fast and Lite have public /models pages?
Not in the published set as of 19 September 2026. Parent Veo 3.1 is published. Fast and Lite are catalog rows without public model pages. This post cites their integers so you can bill the family. It does not link Fast or Lite model URLs. Bookmark Veo 3.1 for the parent row, and read the generate quote for Fast and Lite.
Does 8 seconds of Fast with audio on cost 48 credits?
Yes, on the 19 September 2026 catalog: 8 seconds × 6 discounted credits a second = 48, which equals Fast's listed max_credits. That 48 is the top of Fast, not a surprise fee on top of the 16-credit floor. The 16 is 4 seconds, audio off, discounted. Turn audio on and stretch to 8 seconds, and you have left the floor on purpose.
