Overview

Fermat, based in Barcelona, is a generative AI toolbox built for fashion design rather than general image generation. Its tools cover moodboards, custom style training on a brand’s own references, image generation for concepts and campaigns, and rendering garments and materials onto virtual models, taking a design from an early concept through to a consumer-facing image. The site names Adidas, ASOS, S.Oliver Group, Tendam, Perry Ellis, Riachuelo, New Look and Puig among its customers, positioning it as a tool used inside real fashion and luxury design teams rather than a general creative product retrofitted for the industry.

Generated fashion imagery, including virtual model renders, sits close to questions of body representation and authenticity in advertising, so a brand should have its own policy on disclosing AI-generated or AI-rendered imagery to shoppers. Custom style training on a brand’s proprietary designs also means those references are uploaded to a third-party platform, so review the data-handling terms before sending unreleased collections through the tool. Named customers are a stronger signal than a raw user count, but the specific scope of each engagement, such as which stage of design each brand uses Fermat for, is not detailed on the pages reviewed.

Pro is $30 a month, or $360 a year billed at $330 for an 8% saving, with 150 credits a month, custom image-model training, a commercial licence and high-resolution export, aimed at individuals and freelancers. Studio is $250 a month, or $3,000 a year billed at $2,700 for a 10% saving, with 500 credits a month, unlimited team seats and standard business-hours support, aimed at small teams and agencies. Enterprise is custom-priced, with custom credit volumes, white-label options, a customer success manager, SSO and API access. A free trial includes 1 credit to test the platform, and image generation costs 1 credit while video costs 4.
