What this page is actually deciding
TikTok choices usually fail on four things: vertical output, hook quality, audio workflow, and repeat-posting cost.
9:16 vertical video output (1080x1920 minimum)
10-15 second clip duration per generation
Low cost per second for high-volume posting
Engaging motion and dynamic camera movement
Start with the best fit, not the biggest model list
Each pick answers a different production constraint. Use the top card when quality is the constraint, then move down only when cost, speed, or workflow fit matters more for this page.

Frequently Asked Questions
What resolution should I use for AI-generated TikTok videos?
TikTok's optimal format is 9:16 vertical video at 1080x1920 pixels. Kling v3 Pro is verified up to 1080p vertical output, and Kling 2.5 Turbo and PixVerse v6 also output at 1080p — both sufficient for TikTok's display requirements. Avoid generators that only produce 16:9 and require cropping, as this loses significant frame content.
How much does it cost to generate AI TikTok videos?
Costs range from $0.025/sec (PixVerse v6 without audio) to $0.112/sec (Kling v3). A typical 10-second TikTok clip costs $0.25 with PixVerse v6 without audio, $0.35 with PixVerse v6's cheapest audio tier, $0.42 with Kling 2.5 Turbo, or $1.12 with Kling v3. Creators posting one 10-second clip daily would spend roughly $7.50/month with PixVerse v6 without audio, $10.50/month with PixVerse v6 audio, or $12.60/month with Kling 2.5 Turbo.
Which AI video generators include audio for TikTok?
Several models now generate video with built-in audio. PixVerse v6 starts at $0.025/sec without audio and offers audio/lip-sync from $0.035/sec. Kling v3 ($0.112/sec) supports audio at +50% cost. Grok Video ($0.05/sec) and Sora 2 ($0.10/sec) include audio at no extra charge. For TikTok, native audio saves the step of adding music or voiceover in post-production.
Can AI-generated videos go viral on TikTok?
AI-generated content performs well on TikTok when it combines strong visual hooks with trending audio and good prompts. The key factors are attention-grabbing openings (first 2-3 seconds), dynamic motion, and content that fits current trends. Multi-shot models like Kling v3 Pro (6 shots) and PixVerse v6 enable story-driven content that tends to hold viewer attention longer.
