Image-generation AI startup Reve will shut down its flagship image-generation feature in return for securing new investment from OpenAI. In an official announcement on Sept. 18, Reve said image generation on its website, reve.com, will no longer be available from 12 p.m. Pacific time on Sept. 27. New sign-ups and paid subscription applications were already suspended as of Sept. 17. Existing users can log in until Oct. 31 to download images they created, and paid subscribers who paid September fees will receive full refunds to their original payment method by mid-October. Reve previously said on its official blog that it had secured investment from OpenAI, after which some members of Reve's AI research team moved to OpenAI to lead multimodal research. Reve will retain its status as an independent corporate entity, and it did not disclose the size of the investment. Co-founder and chief product officer Christian Cantrell said a tight coupling of product and research is key in creative software, and the product studio decided to shift its focus from creative tools to other forms of AI-based workflows. Reve unveiled its first product, 'Reve Image 1.0', in March last year, and later released 'Reve 2.0' and 'Reve 2.1', which support 4K-resolution generation and editing.
