About Sora

Sora is OpenAI's text-to-video AI model, first announced in February 2024 and made available to ChatGPT Plus and Pro subscribers in December 2024. Sora generates videos up to 20 seconds long at up to 1080p resolution from text prompts, with capabilities including: realistic motion, consistent characters across scenes, scene-to-scene transitions (Sora's 'Storyboard' feature), and remix/extend existing videos. Sora 2 (launched October 2025) added physics simulation, lip-sync, and audio generation. Sora is included in ChatGPT Plus ($20/month, limited videos) and Pro ($200/month, more generations and higher resolution). Sora generated significant public attention upon its initial demos but faced critique for hallucinations (objects vanishing, physics violations) and limitations vs marketing claims. As of 2026, Sora competes primarily with Runway Gen-3, Google Veo, Kling AI, and Hailuo AI.

Frequently Asked Questions

Is Sora the best AI video generator?

Sora was the most-hyped at launch, but as of 2026 it's not consistently the highest quality. Runway Gen-4, Google Veo 3, and Kling AI 2 are often rated higher in independent comparisons for specific aspects (realism, motion coherence, longer videos). Sora's strengths: included in ChatGPT subscriptions, intuitive Storyboard UX, OpenAI brand polish. Sora's weaknesses: shorter clip lengths, more hallucinations on complex prompts, less control than Runway. For professional video work, Runway or Veo are typically preferred.

How much does Sora cost?

Sora is included in ChatGPT Plus ($20/month) with limited video generations per month at 720p. ChatGPT Pro ($200/month) provides significantly more generations and 1080p resolution. There is no separate Sora-only subscription. For comparison, Runway Standard is $15/month and Pro is $35/month with comparable monthly generation quotas. If you already pay for ChatGPT, Sora is a useful bonus. For dedicated video work, Runway Pro often offers better value.
