DeepMind was acquired by Google as a leading ML startup and now acts as its mostly independent AI division. Its initial goal was to create strong artificial intelligence, which the developers hoped to achieve through the ability to play games (Atari, Go, chess, Dota) and control physical robots. DeepMind gradually took over all of Google's AI projects, including the LLM model and the Gemini chatbot. DeepMind was one of the first to develop multimodal intelligence, including language, code, images, video and 3D world generation. Furthermore, the startup continues projects of creating specialized machine learning systems for various industries, including medicine (drug development) and energy (energy optimization for Google's data centers).

Wayve is developing an end-to-end autonomous driving software Wayve AI Driver based on a proprietary AI model. This approach replaces the modular "sense-plan-act" architecture of the traditional AV1.0 approach with a single neural network trained on diverse data to transform raw sensor inputs into safe outputs. AV2.0 learns driving skills from raw, unlabeled data using self-training, eliminating the need for costly and time-consuming curation of labeled datasets. Wayve also uses generative models of the world for training, creating rich and realistic synthetic scenarios. Wayve's technology does not require HD maps, allowing it to be easily scaled to new roads and cities. Wayve AI Driver is sensor- and hardware-independent and compatible with any type of vehicle.

Synthesia is a platform that specializes in generating "talking head" videos - with realistic avatars reading text. Such videos are used for news, corporate training, presentations and commercials. Video can be automatically translated into 130+ languages and accents. The service generates speech and facial expressions using algorithms, lip-syncs and can even create digital avatars based on real people (after their consent of course). Synthesia is also developing an AI Video Assistant, which can convert text documents into video, helping automate scripting and scene layout. The service is used by many Fortune 100 companies.

Stability AI is developing an open-source model for generating images from text descriptions - Stable Diffusion. The model enables creation of a wide range of image styles, including 3D, photography, painting, line art and more. The model can be installed on a private server or accessed via Stability AI API. The company also provides a Studio for editing images, transforming styles, up-scaling and improving image quality. In addition to the image generation model, Stability AI also develops text-to-video, -audio and -3D models and is collaborating with ARM to optimize its models for mobile devices. Stability AI is constantly facing legal action from stock photo companies like Getty Images for misusing their collection to train their AI-image generation system.
