RunwayML Gen-4 is the superior choice for users prioritizing high-quality, customizable video generation with realistic motion and consistent scenes. GPT-5 is better suited for users who need strong coding capabilities, broad platform integration, and enhanced safety features, but its video generation capabilities are less defined and still under development.
| Attribute | RunwayML Gen-4 | GPT-5 |
|---|---|---|
| Text-to-video generation quality | Excels in generating dynamic videos with realistic motion, maintaining consistency in style, objects, and subjects, and demonstrating superior prompt adherence and world understanding. Attuned for realism, making movies, and the real world. | Excels at coding and can generate front-end UI with minimal prompting. Video generation is available through Sora, though this feature is still rolling out. Supports advanced image understanding and visualization generation. |
| Video resolution and frame rate | 720p (1280x720) at 24 FPS, upscalable to 4K | Not available |
| Control over video style and composition | Allows users to set the look and feel, maintaining coherent world environments and preserving cinematographic elements. Supports live-action, stop-motion animation, smooth animation, VFX, and cinematic styles. | Not available |
| Consistency and coherence of generated video | Maintains consistent characters, objects, and locations throughout scenes, introducing visual memory. | Not available |
| Availability and pricing model | Available to paying customers and businesses, with different pricing tiers and usage limits. Free plan with 125 credits for first-time sign-ups. Standard and Pro plans are also available. | Available to all ChatGPT users, with tiered access: Free Tier (limited access, switches to GPT-5-mini after usage limits), Plus Plan ($20/month, higher message limits), Pro Plan ($200/month, unlimited GPT-5 access, access to GPT-5-pro, advanced features). API Access: GPT-5 ($1.25 per million input tokens, $10 per million output tokens), GPT-5-mini ($0.25 per million input tokens, $2 per million output tokens), GPT-5-nano ($0.05 per million input tokens, $0.40 per million output tokens). |
| Integration with other tools and platforms | Integrates with tools like Blender and offers tools like video inpainting, object removal, and motion tracking. | Integrated into Microsoft 365 Copilot, Microsoft Copilot, GitHub Copilot, and Azure AI Foundry. Integrates with Gmail and Google Calendar. |
| Ease of use for beginners | Designed with simplicity, making advanced AI tools approachable for beginners with a user-friendly interface. | Designed to be beginner-friendly, allowing users to type naturally and still get high-quality results. Easy to use, even without prior experience. |
| Advanced customization options | Provides advanced features for fine-tuning and customizing generated videos, including camera motion controls and subject motion controls. | Users can customize voices and colors. Options to tweak personalities (thoughtful, supportive, sarcastic, etc.). Paid users have further customization options with color themes and output verbosity. |
| Content moderation and safety features | Not available | Includes measures to minimize risks such as hallucinations, sycophancy, and deceptive outputs. Features 'safe completions' and enhanced filtering mechanisms. |
| Training data and bias | Exact details not disclosed. | Trained on public internet data, data from third-party partners, and content created by users or human trainers. Filtering pipeline to cut personal information and harmful content. Part of the training data is synthetic, which can inherit biases and accuracy issues from earlier GPT-4 models. |
| Compute requirements and speed | Gen-4 Turbo delivers 5-second videos in approximately 30 seconds (5x speed increase compared to standard Gen-4). | Optimized for performance and is the fastest model to date. Improved speed when generating long-form content, summarizing documents, or solving code-based tasks. Available in multiple flavors to trade off latency, cost, and capability. |
| Community support and documentation | Offers community support and documentation. | Not available |
| Pricing | Free plan with 125 credits. Standard plan costs $15 per month (or $12 per month with annual billing) and includes 625 credits per month. | Free Tier (limited access), Plus Plan ($20/month), Pro Plan ($200/month). API Access: GPT-5 ($1.25 per million input tokens, $10 per million output tokens), GPT-5-mini ($0.25 per million input tokens, $2 per million output tokens), GPT-5-nano ($0.05 per million input tokens, $0.40 per million output tokens) |
