Runway Gen-4.5 pushes AI video toward professional short-form production with stronger motion, physics, and shot control, while Gen-4 Image remains a separate still-image tool for visual development.
PrunaAI's P-Image, P-Image-Edit, P-Video, and P-Video Avatar make a practical case for compressed AI generation when speed and run cost matter more than chasing the highest possible quality ceiling.
Recraft V4 is competitive as an image model, but its native SVG generation is the real reason designers should pay attention.
PixVerse v5.6 combines video generation, lip sync, and scene editing. The quiet standout is PixVerse Modify, because revision matters more than one perfect first render.
A grounded look at OpenAI Sora 2, Sora 2 Pro, current API status, pricing, limits, strengths, and how it compares with Runway Gen-4.5, Veo 3.1, and Kling 3.0.
GPT Image 2 (gpt-image-2) launched April 2026 as OpenAI's most capable image generation model. It adds native reasoning, near-perfect text rendering, 4K output, multi-image batching, and token-based pricing. Here is what actually changed and how to decide when to use it.
OmniHuman-1.5 from ByteDance animates a portrait image with an audio clip, but the goal is performance -- gestures, emotion, and intent -- not just mouth movement. Here is how the architecture works and what it means for practical use.
Meta SAM 3D Objects is not a normal prompt-to-3D generator. It is a perception-first reconstruction model for understanding and rebuilding objects from existing images.
MiniMax Hailuo 2.3 is a competitive AI video model, but Hailuo 2.3 Fast is the more interesting product for creators who need high-volume draft economics.
Meshy-6 and Tripo v3.1 are the two most capable text-to-3D models right now. They differ in ways that matter depending on what you are making. Here is how to pick the right one.
Lightricks LTX Video 2.3 is open, fast, and practical enough to build around. Here is what changed, how it compares with closed video APIs, and when to use it.
A practical guide to Kling 3.0, Kling O3, native 4K video, and Kling Avatar 2.0 — pricing, durations, and tier advice for picking the right Kling model.
