In their own words
Fermat
Fermat is a generative AI toolbox for fashion and luxury design work, from moodboards to realistic renders, materials and virtual model fitting. Its toolbox lists more than 40 tools arranged by workflow. Designers can turn apparel sketches into photorealistic images, preview fabric before making samples, and alter sleeves, hems, necklines, fit or length without redrawing. Custom Styles uses uploaded visual references to guide image generation. A no-code Tool Editor can package public or private AI models in internal company frontends. Enterprise features include batch processing, API access, custom workflows and custom tools. Fermat says customer prompts, uploads, references and generations are not used to train its models or third-party foundation models; customers retain intellectual property ownership of generations. It lists SOC 2 certification, including SOC Type I and SOC 2 Type II. The free Starter plan includes 1 credit; each image generation costs 1 credit and each video generation costs 4. Pro costs $30 a month and includes 150 credits per month. Fermat offers web and API access.
