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.
