Alibaba released HappyOyster 1.0 on June 17, 2026, an AI service that generates game-like worlds in real time from text or image prompts. Users can move a character with WASD keys, attack, crouch, jump, and dash. The service is free with daily credits through July 17, 2026.
HappyOyster 1.0 generates a world from a text prompt or a starting image, then lets the user move a character through it with keyboard controls. The reviewer entered 'A scene where a maid walks in an alley. Anime-style game like Zenless Zone Zero' and got a third-person view of a maid in an alley who could walk, attack, crouch, jump, and dash. A second test used an image of a maid generated by ChatGPT Images 2.0 with the prompt 'A game where a maid explores a large mansion.' The reviewer noted issues such as the character's face gradually changing and a lag of a few seconds relative to keyboard input, but said the world model produces fewer inconsistencies than existing alternatives. Free credits are distributed daily until July 17, 2026.
