The question
what are the best tools (the best performing, most cost effective etc)
Why it matters
Picking a default AI video stack without a dated, cited comparison means trusting SEO roundups or last year's vendor Elo. This thread already mapped the May 2026 avatar/motion-mimic models; the gap was tools + price for general generation versus that avatar lane.
What we currently believe
As of 2026-08-18 there is no single winner. Lanes:
- Default generate + iterate: gemini-omni-flash — AA T2V-with-audio Elo 1,239 (tied #1) and official ~$0.10/s.
- Open-weight (partial): minimax-h3 — Elo 1,237, $7.80/min; base weights public, IR + 2K regen hosted.
- Still-image animation: seedance-2-0 — AA I2V-with-audio #1 (Elo 1,197) at $9.07/min.
- Long clip / document-to-video: wan-3-0 — official 30 s, $0.10/s 720P / $0.20/s 1080P; no AA Elo yet.
- Scripted talking head: heygen-avatar-v on HeyGen credits (Avatar V = 48 credits/min).
- Performance-driven character: runway-act-two at 5 credits/sec.
- Do not buy for "best quality": veo-3-1 Standard ($0.40/s, Elo ~1,089) or Sora 2 Pro ($0.30–$0.70/s, no top-28 AA row).
Full tradeoff: ai-video-quality-versus-cost. Ranking method: artificial-analysis-video-arena.
Evidence we have
- From 2026-08-18-autoresearch-best-ai-video-generation-tools (2026-08-18): Artificial Analysis T2V-with-audio table — Omni Flash 1,239 / $6.00/min; MiniMax H3 1,237 / $7.80/min; Seedance 2.0 1,222 / $9.07/min; Veo 3.1 Standard 1,089 / $24.00/min.
- From 2026-08-18-autoresearch-best-ai-video-generation-tools: official Gemini API prices — Omni Flash ≈ $0.10/s; Veo 3.1 Standard / Fast / Lite $0.40 / $0.10–$0.12 / $0.05–$0.08 per second (audio on).
- From 2026-08-18-autoresearch-best-ai-video-generation-tools: official OpenAI Sora 2 $0.10/s 720p; Sora 2 Pro $0.30–$0.70/s.
- From 2026-08-18-autoresearch-best-ai-video-generation-tools: official Wan3.0 Model Studio $0.05/s 480P, $0.10/s 720P, $0.20/s 1080P; 30 s single pass.
- From 2026-08-18-autoresearch-best-ai-video-generation-tools: HeyGen Creator $29 / 600 credits; Avatar V 48 credits/min on the rate card (pricing-page FAQ still says 20 — unresolved).
- From 2026-08-18-autoresearch-best-ai-video-generation-tools: Runway Academy — Act-Two 5 credits/sec, Gen-4.5 12 credits/sec; Runway's Dec 2025 "Elo 1,247 #1" claim is stale vs the live AA table.
- From 2026-05-07-ai-avatar-motion-mimicking-models-survey: prior avatar taxonomy (wan-animate, runway-act-two, heygen-avatar-v) — not re-surveyed.
Evidence we need
- AA (or anyone independent) Elo for wan-3-0 and for avatar-specific tasks.
- Official Kling 3.0 list prices (klingai.com returned 446).
- Fetched confirmation of the Sora consumer/API sunset (help.openai.com timed out).
- Retry / failure rates so "dollars per usable clip" can replace list $/s.
- Whether local minimax-h3 matches hosted Elo without Context-IR.
How to resolve
Status is narrowed, not resolved: we have a dated default stack and we can reject Veo Standard / Sora 2 Pro as quality leaders, but "best" still depends on lane, and avatar benches remain independent-avatar-benchmarks. Re-open if AA's top three rotate or Wan3.0 lands an Elo.
