Best AI Models in the UK

LTX is an open foundation model for video, audio, and world simulation. You get full control over your AI: run LTX locally on your own hardware, fine tune it on your own IP, and generate video and audio as one unified output instead of stitching together separate tools. The latest model, LTX-2.5, is a 22B-parameter dual-stream diffusion transformer that generates native 4K video at up to 50fps, with synchronized audio and video produced in a single pass. Weights, code, and research are fully open, and independent benchmarking from Artificial Analysis ranks LTX among the top 3 AI video models globally. Access LTX three ways: download the open weights and run it yourself, license the model for on-premise deployment with enterprise support, or build on LTX Studio, the production suite for creative teams and studios. Teams at ElevenLabs, Asteria Film Co., Magnopus, and NVIDIA already build on LTX. LTX is production infrastructure for AI teams generating motion and physical environments inside their own pipelines, not a consumer app for one-off clips.

Wan2.2 Animate is a specialized module within the Wan video generation framework designed for high-fidelity character animation and character replacement, enabling users to transform static images into dynamic videos or swap subjects within existing footage while preserving realism and motion consistency. It works by taking two primary inputs: a reference image that defines the character’s appearance and a reference video that provides motion, expressions, and scene context. Using this combination, it can animate a still character by replicating body movements, gestures, and facial expressions from the source video, or replace the original subject in a video while maintaining the original lighting, camera movement, and environment for seamless integration. It relies on advanced techniques such as spatially aligned skeleton signals and implicit facial feature extraction to accurately reproduce motion and expressions.
