Best AI Video Aggregator 2026 — head-to-head

A platform that runs multiple different AI video models (Sora, Kling, Veo, etc) under one subscription, instead of locking you to one engine. The opposite of single-vendor tools like Runway (only their Gen models) or pure ChatGPT (only Sora). Aggregators give you the choice; the trade-off is no aggregator runs every model, and the picking-the-right-model burden falls on you (unless the aggregator solves that — which is what gVideo's Smart Picker does).

Three reasons: (1) No single AI video engine wins every scene — Sora photoreal hero, Kling character motion, Veo native audio, Hailuo anime. Aggregators let you pick the right tool. (2) Single-vendor pricing is calibrated for power users; if you're casual or mixed-use, you overpay. (3) Single-vendor lock-in means switching costs as the field evolves — a new flagship from a different lab leaves you stuck or paying a second subscription.

Three differentiators: (1) AI Smart Picker reads your prompt and recommends the top 3 models — the others give you a model dropdown and let you guess. (2) One-click 'Generate all 3 side-by-side' runs the picks in parallel — you compare actual outputs instead of switching models manually. (3) gVideo runs flagship-only versions (Sora 2 Pro not Sora 1, Kling 3.0 not 2.5, Veo 3.1 not 3.0) — fewer choices but no wasted credits on outdated models.

By raw count: Pollo AI (20+ including legacy versions), then Krea (~70 total but most are image), then gVideo (11 video flagships + 2 avatar). By 'flagship video models that matter,' gVideo's 11 is the deepest curated set — Sora 2 Pro, Kling 3, Veo 3.1, Luma Ray 2, Hailuo, Seedance, Pika, Wan, plus i2v + 2 avatar — without older versions cluttering the picker.

Same model = same output. Aggregators run the actual vendor models via fal-hosted endpoints (gVideo, Pollo, Higgsfield) or direct vendor APIs (Krea sometimes). The render quality is identical to using the vendor directly; aggregators add the multi-model UX, billing, and history layers on top.

Hard to compare cleanly — different aggregators meter differently (credits / tokens / minutes). For typical creator volume (~30 short clips/month with mixed model use), gVideo Pro at $39.99/mo with the credit-pool model and AI Smart Picker tends to be most efficient. Pollo can be cheaper at very high volume on cheap-tier models. Krea splits credits across image+video, so video-heavy users effectively pay more.
