🎥 Runway Gen-4.5

Launched in December 2025, Runway Gen-4.5 set a new standard for AI video generation. It is the preferred tool of studios and professionals who prioritize quality above all else.

Unprecedented Physical Accuracy

Gen-4.5 understands real-world physics: gravity, reflections, shadows, and material interactions. Objects fall naturally, liquids flow correctly, and fabrics move realistically. It’s the most “cinematic” tool available.

4K output

Generates videos in native 4K resolution, ideal for professional production intended for large screens, high-quality YouTube, or broadcast material.

Consistency with Reference Images

Send an image of a character, and Gen-4.5 keeps its appearance consistent in the generated video. Perfect for turning Midjourney images into video clips.

Gen-4 Turbo

An optimized version of Gen-4 that's 5x faster and costs just 5 credits per second. Ideal for quick iterations and high-volume production. Slightly lower quality than Gen-4.5, but excellent for most use cases.

🎬 Pika 2.5

Pika 2.5 stands out with exceptionally sharp visuals and a unique feature: Pikaformance.

Sharper Visuals and Smoother Camera

Pika 2.5 produces videos with impressive sharpness and extremely smooth camera movements. Great for clean, commercial content.

Pikaformance — Hyper-realistic Lip-sync

Pika 2.5’s standout feature. Pikaformance is a hyper-realistic facial expression model that lets you create perfect lip sync. Upload audio and a reference image, and Pika animates the face with natural expressions synchronized with the speech. Revolutionary for talking head videos.

AI Video Editing

In addition to generating videos, Pika lets you edit existing videos: swap objects, change styles, add/remove elements. It works like a "Photoshop for video."
