LetzAI rapidly scales AI-powered image generation for global users
Everywhere Inference reduces the latency of our output and enhances the performance of AI-enabled apps, allowing us to optimize our workflows for more accurate, real-time results.Misch Strotz, CEO and co-founder, LetzAIA futuristic tram journey, blending reality and imagination, created with LetzAI. Destination: To the MoonLaunched as a skunkworks project from within Neon Internet, LetzAI is quickly becoming a go-to platform for high-quality AI-generated images. With a mission to democratize and personalize AI-powered image generation, it has emerged as one of the most popular and high-quality options on the market. To support its rapid growth and scale seamlessly, LetzAI partnered with Gcore for advanced AI and cloud infrastructure.Global GPU shortages threaten to derail a new AI image generation ideaIn 2023, Neon Internet CEO and co-founder Misch Strotz was struck by a clever idea: give Luxembourg residents the power to easily generate local images using AI. Within a month, Luxembourg-focused LetzAI V1 went live.Encouraged by strong local demand, Strotz and his team began working on a global version of the platform. The vision? An opt-in AI platform empowering brands, creators, artists, and individuals to unlock endless creative possibilities by adding their own images, art styles, and products. “Other AI platforms scrape the internet, incorporating people and their content without permission. We wanted to put the choice and power in each person’s hands,” Strotz explains.Before long, the team began working on V2. In addition to generating higher quality and more personalized AI-generated images, V2 would drive consistency across objects, characters, and styles. After uploading their own photos and creating their own models, users can blend them with other models created by the community to create an endless number of unique images.However, LetzAI faced a significant hurdle in training and launching V2—a global GPU shortage. With limited resources to train its models, LetzAI needed a reliable partner to help evolve its AI-driven platform and keep it operating smoothly.Finding a trusted, Europe-based AI partnerIn the search for a fitting partner, Strotz spoke to major vendors including hyperscalers and various Europe-based providers. Meeting Gcore’s product leadership team made the decision clear. “It was amazing to meet executives who were so knowledgeable about technology and took us seriously,” recalls Strotz.Gcore’s approach to data security and sovereignty further solidified the decision. “We needed a trusted partner who shared our commitment to European data protection principles, which we incorporated into the development of our platform” he continues.Maximizing AI efficiency by training on local GPUsLetzAI opted for Gcore’s state-of-the-art NVIDIA H100 GPUs in Luxembourg. “This was the perfect option, allowing us to keep our model training and development local. With Gcore, we can rent GPUs rather than entire servers, making it a far more cost-effective solution by avoiding unnecessary costs like excess storage and idle server capacity,” Strotz explains. This approach provided flexibility, efficiency, and high performance, tailored specifically for AI workloads.LetzAI was able to adapt its app to run in containers, configure model training tasks to run on GPU Cloud, and use Everywhere Inference for image generation and upscaling. “Everywhere Inference reduces the latency of our output and enhances the performance of AI-enabled apps, allowing us to optimize our workflows for more accurate, real-time results,” Strotz says.In just two months, LetzAI V2 launched to serve users around the world. And Strotz and team were already developing its successor.Empowering creativity with scalable, high-performance AI infrastructureWith Gcore’s continued support, LetzAI quickly deployed V3. “The Gcore team was incredibly responsive to our needs, guiding us to the best solution for our evolving requirements. This has given us a powerful and efficient infrastructure that can flex according to demand,” says Strotz.Running V3 on Gcore means LetzAI users experience fast, reliable performance. Artists, individuals, and brands are already putting V3 to use in interesting ways. For example, in response to what LetzAI calls its ‘AI Challenges’, a Luxembourg restaurant chain prompted residents to create thousands of images using its model of a pizza.In another example, LetzAI teamed with digital agency LOOP to dress PUMA’s virtual influencer and avatar, Laila, in a Moroccan soccer jersey. According to Strotz, “PUMA had struggled to make clothing look realistic on Laila. When they saw our images, they said the result was 1,000 times better than anything they had tried.”That wasn’t the only brand intrigued by V3’s possibilities. After LetzAI posted V3-generated images of models wearing Sloggi underwear, Sloggi’s creative agency STAN Studios asked LetzAI to generate more images for market testing.Always looking for new ways to support creators, LetzAI also launched its Image Upscaler feature, which enhances images and doubles their resolution. “Our creators can now resolve common AI image issues around quality and resolution. Everywhere Inference is pivotal in delivering the power and speed needed for these dynamic image enhancements,” notes Strotz.Platform evolution and AI innovation without limitsAs its models exceed user expectations worldwide, LetzAI can rely on Gcore to handle a high volume of requests. Confident about generating a limitless number of high-quality images on the fly, LetzAI can continue to scale rapidly to become a sustainable, innovation-driven business.“As we further evolve—such as by adding video features to our platform—our partnership with Gcore will be central to LetzAI’s continued success,” Strotz concludes.
fan.at expands audience reach and boosts subscription revenue by 133%
By expanding our game coverage, we’ve seen a surge in new subscriptions, leading to a 133% increase in revenue within just one quarter, which is a great result. Raphael Hollenstein, Senior Software Engineer at fan.at fan.at is a sports broadcaster and streaming platform for football and handball sporting events. The company’s website and mobile app offer sports fans hundreds of live streams of men’s, women’s, and youth games, plus on-demand videos, personalized feeds, highlights, news, voting, live ticker, player statistics, and match results. Viewers can enjoy live streams and replays of games from major leagues and championships like the Bundesliga, Premier League, and Gold Cup. With video content from 50,000 games played by 15,000 teams per season, fan.at delivers high-volume broadcasts to an engaged and growing viewer base. Lacking scalability to support multi-stream delivery fan.at wanted to meet the growing demand for more game coverage, expanding beyond major national leagues to include smaller regional clubs and junior leagues. The company faced a significant challenge in adding these live streams. “Our previous streaming partner could not support our plans to scale, so we initially brought the technology in-house. This meant that we needed to establish a new streaming setup and supporting infrastructure under tight deadlines,” said Raphael Hollenstein, Senior Software Engineer at fan.at. While the company had automated cameras installed at football and handball venues to record games, it lacked the necessary infrastructure to efficiently ingest, transcode, and deliver multiple streams to its growing audience. This prompted the team to explore external solutions. “When we spoke to providers, many couldn’t offer the functionality we needed, like graphical overlays and sponsor inserts, while others were simply too expensive for managing multiple simultaneous streams. It wasn’t a scalable option,” explained Hollenstein. fan.at turned to Gcore for a solution that could support its current and future growth plans, attracted by features like free encoding, which significantly reduces costs. Gcore offered all the essential functionality, including simultaneous live streaming of multiple matches, video-on-demand (VOD), the ability to add sponsor inserts and overlays, and the option to create and edit video clips using the API. fan.at selected Gcore Video Streaming and CDN due to its high-quality, low-latency performance, scalability, and global reach—all of which were essential for supporting the broadcaster’s expansion plans and meeting the demands of additional streams and a larger audience. Delivering game-changing sports coverage to a global audience fan.at integrated Gcore Video Streaming and CDN into its existing workflow, enabling a smooth transition that strengthened its streaming capabilities without disruption. “The Gcore implementation was seamless, and the platform provides everything we need in one place, from live ingest to low-latency global delivery,” said Hollenstein. “It’s been a game-changer, allowing us to focus on scaling our content without the technical hurdles.” Using Gcore’s fast and flexible CDN, fan.at can deliver large, continuous data streams with minimal buffering and latency for an uninterrupted viewing experience. “With Gcore, we no longer have to worry about transcoding our media,” said Hollenstein. “Gcore’s solution automatically converts video files between formats so that our content is always delivered at the highest quality and accessible to all viewers, regardless of internet stability, bandwidth, resolution, or screen size.” With the right technology foundations in place, fan.at could install over 130 additional cameras at sports venues, successfully expanding coverage of smaller regional club games. The efficient management of these additional streams by Gcore made the expansion process simple and hassle-free for the team. Meeting customer demand for these games unlocked new financial opportunities for the broadcaster. “By expanding our game coverage, we’ve seen a surge in new subscriptions, leading to a 133% increase in revenue within just one quarter, which is a great result,” Hollenstein notes. Elevating live sports viewing experience and fan engagement Fast clip creation is crucial for enriching the game experience and broadening audience reach on social media. “We use the API to create instant highlight videos from live streams, which is exactly what we needed,” said Hollenstein. “We can produce clips almost instantaneously, which is crucial when managing up to 300 cameras during peak weekends.” The ability to create short videos for social media has also helped to grow brand awareness and interaction. “Within four months of implementing Gcore, social media engagement with video content rose by 43%, and video views on Instagram increased by 64%,” added Hollenstein. Gcore enables fan.at to create customizable graphical overlays, superimposing information like scores, player stats, and logos directly onto the footage. This feature offers fans additional context that complements the on-field action and improves the viewing experience. The broadcaster can also insert HTML overlays like sponsor banners, alerts, and a time clock into live streams, enhancing visual appeal and engagement. Streamlining broadcast operations and reducing streaming costs fan.at streamlined operations and reduced costs by consolidating its streaming infrastructure with Gcore’s integrated transcoding and VOD storage solutions, eliminating the need for multiple providers. We’ve seen a 13% reduction in VOD storage costs and an 85% decrease in transcoding expenses compared to our previous providers. Raphael Hollenstein, Senior Software Engineer at fan.at Additionally, Gcore’s automated video streaming and production workflows saved the engineering team 500 working hours over four months, further enhancing operational efficiency. Continued innovation to grow and engage a diverse audience By partnering with Gcore, fan.at has successfully expanded its broadcast capabilities beyond major leagues to include coverage of football games from smaller clubs, reaching a wider audience. The collaboration enabled the broadcaster to meet growing demand, optimize streaming performance, and enhance viewer engagement. Looking ahead, fan.at plans to rely on Gcore to add live commentary, innovate further with video editing, and explore new interactive features to continue delivering high-quality entertainment to an ever-growing audience.
