Grok Imagine vs Veo 3.1 is range versus fidelity. Grok Imagine Video 1.5 runs longer clips in nine aspect ratios; Veo 3.1 reached 4K with tight shot control. Here is the spec-by-spec breakdown — plus where each model is actually sold in late 2026.
imaginegrok.org is independent and is not affiliated with xAI or Google / DeepMind. The generator on this site runs Grok Imagine video — short image-to-video clips. This Grok Imagine vs Veo comparison, specifically Grok Imagine vs Veo 3.1, the last Veo release documented on the Gemini API, is drawn from xAI developer docs, Google's Gemini docs, and third-party tests we attribute rather than endorse.
The workspace on this page runs Grok Imagine video — short image-to-video clips at 480p or 720p from one still. It does not run Veo. Use the Grok Imagine vs Veo breakdown below to decide which model your brief needs.

Only the Grok Imagine side is shown here. We did not render a Veo clip: Google shut the Veo 3.1 Gemini API Preview endpoints down on October 22, 2026, so there is no live Veo generation to pair against it. The clip below is Grok Imagine image-to-video — 6 s, 480p-class, with native audio.
Four clear steps from prompt to finished output — built for creators who want results without an X Premium maze.
Grok Imagine Video 1.5 takes text and image prompts, up to 14 reference images and 3 voice references, plus first/last frames and up to 4 keyframes. Clips run 1–15 s at native 1080p with lip-synced speech — or silent, with generate_audio=false.
Veo 3.1 takes text-to-video and image-to-video, up to 3 reference images, first + last frame interpolation, and native audio. Clips run 4, 6, or 8 s at 720p, 1080p, or 4K (1080p and 4K require the 8 s duration), in 16:9 or 9:16, delivered as 24 fps MP4 with SynthID watermarking.
Google shut the Veo 3.1 Preview endpoints in the Gemini API (veo-3.1-generate-preview, veo-3.1-fast-generate-preview, veo-3.1-lite-generate-preview) down on October 22, 2026, directing developers to Gemini Omni Flash (gemini-omni-1.1-flash) or GA models on the Gemini Enterprise Agent Platform. Grok Imagine Video 1.5 is live in the xAI API today.
Grok Imagine vs Veo is not one score. A 4K hero shot or a low-motion product mood board leaned Veo in tests. A 15 s talking clip, a 21:9 canvas, pinned keyframes, or a voice reference leans Grok Imagine.
Capabilities tuned for the keyword intent of this page — not a generic feature dump.
Grok Imagine Video 1.5: text/image-to-video, native 1080p, 1–15 s, up to 14 reference images and 3 voice references, first/last frame plus up to 4 keyframes, native audio with lip-synced speech, aspect ratios 1:1, 16:9, 9:16, 4:3, 3:4, 3:2, 2:3, 21:9, and 5:2. Veo 3.1: 4/6/8 s clips, 720p/1080p/4K (4K not on Lite), 16:9 or 9:16, native audio, up to 3 reference images, first + last frame interpolation, video extension (not on Lite; extension capped at 720p), SynthID watermarking, 24 fps MP4.
Both models generate native audio. Grok Imagine Video 1.5 ships lip-synced speech, accepts 3 voice references, and can render silent clips with generate_audio=false. In Contra Labs' June 2026 head-to-head, Grok Imagine led on people and human performance while Veo specialized in low-motion product and mood shots.
Veo 3.1 tops out at 8 s per clip but reaches 4K, with 1080p and 4K requiring the 8-second duration. Grok Imagine Video 1.5 runs 1–15 s at native 1080p with no 8-second minimum. The Grok Imagine vs Veo length gap matters for social cuts; the resolution gap matters for big screens.
Grok Imagine Video 1.5 renders nine aspect ratios — 1:1, 16:9, 9:16, 4:3, 3:4, 3:2, 2:3, 21:9, 5:2 — and pins a first frame, a last frame, and up to 4 keyframes. Veo 3.1 offers 16:9 and 9:16 with first + last frame interpolation and up to 3 reference images. Extension exists on both sides: Veo extends (720p max, not on Lite); Grok extends via grok-imagine-video, adding 2–10 s to sources up to 8.7 s, also capped at 720p.
Grok Imagine Video 1.5 API is published at $0.08/s (480p), $0.14/s (720p), and $0.25/s (1080p); the Lite variant is $0.02 / $0.03 / $0.14 with 1080p upscaled from 720p. Veo 3.1's Gemini API Preview rates were $0.40/s Standard with audio (720p/1080p, $0.60 at 4K), $0.10–$0.12/s Fast, and $0.05–$0.08/s Lite. Google's English pricing page no longer lists Veo after the October 22, 2026 shutdown; Gemini Omni Flash is approximately $0.10/s at 720p.
Contra Labs' head-to-head (June 29, 2026) called Seedance 2.0, Grok Imagine, and Veo 3.1 a near-tie: of 10 prompts, Seedance won 4, Grok Imagine 3, and Veo 3.1 3 — Veo specializing in low-motion product and mood shots, Grok Imagine strongest on people and human performance. fal's comparison (June 13, 2026) is a useful read on fal's reseller pricing, but its Grok rows — max 720p, 10 s, $0.05–$0.07 — are outdated against the current xAI 1.5 docs, so we cite xAI for Grok specs.
imaginegrok.org generates short Grok Imagine image-to-video clips at 480p or 720p from one still. It is independent, not affiliated with xAI or Google / DeepMind, and does not run Veo. Credits here are unrelated to either company's API pricing.
The Grok Imagine vs Veo decision follows the shot. A 4K product hero or a low-motion mood board leans Veo lineage; a 15 s talking clip, a 21:9 canvas, or pinned keyframes leans Grok Imagine Video 1.5.
Grok Imagine Video 1.5 is $0.08–$0.25 per second by resolution. Veo's last Preview rates ran $0.05–$0.60 per second by tier and resolution. On imaginegrok.org a default 5 s clip is 2 credits — see /pricing. Three ledgers; do not mix them.
Do not present Veo 3.1 Preview prices as currently buyable on the Gemini Developer API. The successors Google names are Gemini Omni Flash (gemini-omni-1.1-flash, approximately $0.10/s at 720p) and GA models on the Gemini Enterprise Agent Platform. This Grok Imagine vs Veo page compares documented Veo 3.1 specs because that is the comparison people search for.
Averages hide prompt-specific wins. If your shot is a close-up with speech or a still product loop, test that exact prompt on Grok Imagine and on a current Veo-lineage model instead of trusting one leaderboard.
On imaginegrok.org, the Grok Imagine vs Veo question is external — this site's workspace is image-to-video at 480p/720p. Start at /grok-image-to-video or /grok-imagine-1-5.
You need the Grok Imagine vs Veo side-by-side on duration, resolution, audio, aspect ratios, and price before you sign a vendor — including where each model is actually sold in late 2026.
Contra Labs saw Veo specialize in low-motion product and mood shots. If your brief is a 4K hero loop, the Veo lineage is the shortlist; this page tells you what changed after October 22, 2026.
Grok Imagine led on people and human performance in the same test, and its 1–15 s clips with lip-synced speech and voice references fit interviews, podcast cuts, and UGC.
Grok Imagine publishes per-second rates; Veo's numbers are historical Preview rates or successor pricing. This page labels which is which instead of inventing a live Veo price.

Grok Imagine vs Veo is range and voice control versus resolution ceiling.
Veo 3.1 reached developers as Preview endpoints in the Gemini API — veo-3.1-generate-preview, veo-3.1-fast-generate-preview, and veo-3.1-lite-generate-preview. Google shut them down on October 22, 2026 and directs developers to Gemini Omni Flash (gemini-omni-1.1-flash) or to GA models on the Gemini Enterprise Agent Platform. That availability change is why the honest Grok Imagine vs Veo answer in late 2026 compares live Grok Imagine Video 1.5 specs against documented Veo 3.1 specs, and points Veo-bound buyers at the successors above. Grok Imagine Video 1.5 remains live in the xAI API at https://docs.x.ai.
xAI publishes Grok Imagine Video 1.5 at $0.08/s 480p, $0.14/s 720p, and $0.25/s 1080p, with the Lite variant at $0.02 / $0.03 / $0.14 (1080p upscaled from 720p): https://docs.x.ai/developers/pricing. Veo 3.1's Gemini API prices are historical — from Korean and archived pricing tables while the Preview was live, quoted "with audio": Standard $0.40/s (720p/1080p) and $0.60/s (4K); Fast $0.10/s (720p), $0.12/s (1080p), $0.30/s (4K); Lite $0.05/s (720p) and $0.08/s (1080p). Google's English pricing page no longer lists Veo after the October 22, 2026 shutdown; Gemini Omni Flash is approximately $0.10/s at 720p (https://ai.google.dev/gemini-api/docs/pricing). fal's marketplace posts its own reseller rates for both models — those are fal's prices, not xAI's or Google's list prices. On imaginegrok.org, credits are a separate ledger: a default 5 s Grok Imagine clip is 2 credits; see /pricing. Credits are not xAI API prices and not Google prices.
Pick Grok Imagine Video 1.5 when you need 1–15 s clips, native 1080p without an 8-second minimum, nine aspect ratios, up to 4 keyframes, 14 reference images, or 3 voice references — at a flagship rate of $0.25/s. Pick the Veo lineage when the brief is 4K fidelity or low-motion product and mood shots — exactly where Contra Labs saw Veo win its prompts. Buy it today through Gemini Omni Flash or GA models on the Gemini Enterprise Agent Platform, not through the retired Veo 3.1 Preview endpoints. Grok Imagine vs Veo 3.1 on paper favors Grok for range and price; it favors Veo for resolution ceiling. If you are already on imaginegrok.org, you are on the Grok Imagine side for short image-to-video clips — start at /grok-imagine-1-5 or /grok-image-to-video. For pinned frames see /grok-imagine-keyframes; for credit packs /pricing; for the Seedance near-tie /grok-imagine-vs-seedance; for non-Grok options /grok-imagine-alternative. imaginegrok.org runs Grok Imagine video, is independent, and is not affiliated with xAI or Google / DeepMind.
