Sora 2 vs Veo 3.1 vs MiniMax 2.3: Which AI Video Model in 2026
A Gensta.ai-accurate comparison of Sora 2, Veo 3.1, and MiniMax 2.3: resolution, duration, audio, speed, and when to pick each — plus when Wan or Seedance is the better tool.
Sora 2 and Sora 2 Pro: realism and emotion
OpenAI's Sora 2 is a strong pick when people, motion physics, and a cinematic feel matter. On Gensta.ai it supports text-to-video and image-to-video. Durations are 4, 8, or 12 seconds. Base Sora 2 is 720p; Sora 2 Pro adds 1080p with the same duration options. Audio on Sora is always on.
Choose Sora 2 for realistic portraits, emotional scenes, or premium social clips. Versus MiniMax, expect higher cost and longer waits. Content filters are strict: this is not an 'uncensored porn' tool — prohibited content is banned on every model on Gensta.ai.

Google DeepMind's Veo 3.1 is strong on camera work and lighting. Durations are 4, 6, or 8 seconds; resolutions 720p and 1080p; both text-to-video and image-to-video. Key detail: audio can be turned on or off — useful when you don't want a track or will add your own music later. Veo 3.1 Fast is cheaper and quicker with the same mode set.
Pick Veo for ad-style camera moves and controllable audio. It is not the only audio-capable model on Gensta.ai — Sora and Wan also have audio — but Veo is more flexible on audio on/off.

MiniMax 2.3 is the workhorse for drafts and bulk tests. It supports text-to-video and image-to-video, 6 or 10 seconds, 768p and 1080p. No audio — picture only.
MiniMax 2.3 Fast is even cheaper and faster, but one product fact matters: Fast is image-to-video only. If you're writing a scene with no photo, use regular MiniMax 2.3, Sora, or Veo.
Choose MiniMax when you need to validate an idea quickly, ship many Reels variants, or stay on budget. Final hero clips are often worth finishing on Sora or Veo.
Try on Gensta.aiComparison and scenario verdicts
Gensta.ai facts in short: • People realism: Sora 2 / Pro ≥ Veo ≥ MiniMax. • Audio control: Veo (on/off) > Sora/Wan (usually always on) > MiniMax (no audio). • Speed and cheap tests: MiniMax Fast (photo→video only) and MiniMax 2.3. • Clip length: Sora up to 12s; MiniMax up to 10; Veo up to 8. Need up to 15s and references — Seedance 2.0 or Wan 2.7. • Art/animation: Wan, not this trio. • Exact dance from a reference video: Kling Motion, not Sora/Veo/MiniMax.
Workflows that usually work: 1) Photo draft on MiniMax Fast → people final on Sora 2. 2) Product ad with a camera push-in → Veo 3.1 (turn audio off if you'll add your own track). 3) Many Reels variants in one evening → MiniMax 2.3 / Fast, without paying premium on every draft. 4) Need a move copied from a TikTok reference → Motion Control immediately; don't try to describe the dance in Sora text.
Verdict: photo draft — MiniMax Fast; budget text-to-video — MiniMax 2.3; premium people — Sora; ads with camera + optional audio — Veo.

Open the Video tab and run the same prompt on two models from the trio — in a few minutes you'll see whose motion style you prefer. For photo starts, keep MiniMax Fast as the draft lane and Sora 2 as the final lane. If two runs still miss the mark, change one variable at a time: shorter duration or a single-action prompt.
