FLUX 3 Max vs Kling, Seedance, Veo, Wan: AI Video Arena

👁 113 reads

On October 20, 2026, I put FLUX 3 Max through the exact same five benchmark scenes I have been using since October 8 to evaluate video models in my AI video arena. The result: an 8.8/10 average, matching Wan 3.0 and landing just 0.1 points behind the base FLUX 3 Video model. Rivals like Kling 3.0 Standard (6.6), Seedance 2.5 (5.6), and Veo 3.1 Lite (4.8) fell far behind, tripped up primarily by Polish diacritics. In the same test run, I also evaluated the newly added Grok Imagine Video 1.5 Lite, which posted a 7.0/10 score for just ten cents. You can find the complete overview in my FLUX 3 Max hub.

Scoreboard

Average score across 5 benchmark scenes on a 0-10 scale. Cost per 5-second clip based on the pricing tier used during each specific round (via API or fal.ai), before sales tax.

FLUX 3 Max cost the same as Wan 3.0 in this round, but at 720p instead of 480p. Keep in mind this reflects promotional launch pricing on fal (75% off through November 7, 2026). Standard non-promotional pricing for 5 seconds at 720p is $0.85. Note that fal notes FLUX 3 Max as a variant post-trained by fal rather than a stock base checkpoint from Black Forest Labs. More of my independent tests are collected in the Lab of this blog.

FLUX 3 Max vs Kling, Seedance, and Rivals: Scene by Scene

Chalkboard Text: “ŻÓŁTA ŁÓDŹ”

This test scene created the sharpest divide across the board. FLUX 3 Max wrote both lines in realistic chalk, preserving every dot and accent mark over Ż, Ó, and Ź, alongside the stroked Ł characters - matching the flawless output of base FLUX 3 Video and Wan 3.0. Grok Imagine 1.5 Lite also reproduced the text accurately, but rendered it as a digital sans-serif font while the hand drew an unrelated squiggle next to it.

Polish Speech Challenge

Spoken line prompt: “W Szczebrzeszynie chrząszcz brzmi w trzcinie, a ja płacę trzydzieści dwa złote”. Audio was transcribed via Wizper, calculating word error rate (WER) after converting digits to words.

• FLUX 3 Max: “Wszczebrzeszenie chrząszcz brzmi w trzcinie, a ja płacę 32 złote” - WER 0.167 (merged the first two words).
• Grok Imagine 1.5 Lite: “…brzmi w trzczynie…” - WER 0.083, but the model inserted forced burned-in subtitles at the bottom despite explicit negative prompting. That dropped its score to 7.0.
• FLUX 3 Video (Oct 11): completely error-free audio track, WER 0.

Camera Motion, Water Physics, and Multi-Shot Character

Rendering Speed

I did not measure generation latency in earlier Arena rounds because those ran through a different API pipeline. On October 20 on fal.ai, FLUX 3 Max rendered each 5-second clip in 12-22 seconds from prompt submission to finished video file. Grok 1.5 Lite took 22-31 seconds. By contrast, animating the same bakery still image in Seedance 2.5 took 197 seconds. I covered those benchmarks in detail in my FLUX 3 Max speed analysis.

Which Video Model Should You Choose?

• Crisp on-screen typography and low 720p cost: FLUX 3 Max while the promotional rate lasts through November 7, then Wan 3.0.
• Complex Polish dialogue: base FLUX 3 Video or MiniMax H3 Max (both achieved a WER of 0 in my tests).
• Controlled camera moves inside a web dashboard: Kling 3.0 - it maintained steady orbit geometry and has a dedicated interface (Kling referral link), though it struggles heavily with Polish text rendering.
• Ultra-cheap concept drafts: Grok Imagine Video 1.5 Lite - $0.10 for 5 seconds at 480p with audio, though multi-shot cuts and water physics fall short.

Benchmark Methodology

• Identical English text prompts across all models (only the on-screen text and spoken lines were in Polish), 16:9 aspect ratio, 5 seconds duration, zero starting reference image, single-shot generation.
• FLUX 3 Max was run at 720p (no lower resolution is exposed), native audio generation enabled, default prompt expansion active. Grok Imagine 1.5 Lite was run at 480p.
• Scoring criteria evaluated the dynamic full clip along with four extracted stills (at 8%, 35%, 62%, and 92% timeline progress) side by side, inspecting the final text frame at full resolution.
• Scores for Wan 3.0, H3 Max, Kling, Seedance, Veo, and Runway date from October 8, 2026, and FLUX 3 Video from October 11, 2026, using the exact same prompts and evaluation standards.
• Total testing cost for the October 20 round: $1.06 for FLUX 3 Max (5 clips) and $0.50 for Grok 1.5 Lite (5 clips) via fal.ai.

Frequently Asked Questions

Is FLUX 3 Max better than FLUX 3 Video?

In my 5-scene test suite, no: it scored 8.8 versus 8.9. However, it generates significantly faster and is roughly a quarter of the cost during its launch promotion. On the Artificial Analysis image-to-video leaderboard, Max ranks 52 Elo points above base FLUX 3.

Which AI video generator handles Polish text best?

The prompt phrase “ŻÓŁTA ŁÓDŹ” was reproduced without spelling errors by FLUX 3 Max, FLUX 3 Video, Wan 3.0, MiniMax H3 Max, and Grok Imagine 1.5 Lite (the latter using a digital printed font rather than handwritten chalk).

Does Grok Imagine Video 1.5 Lite support native audio?

Yes. In my test generations via fal.ai, clips included synchronized sound effects and spoken Polish dialogue.
