LTX
Most AI video tools hand you a black box: closed weights, a subscription, and no way to see what is happening under the hood. LTX takes the opposite approach. Built by Lightricks, LTX is an open foundation model that generates and simulates across video, audio, and the physical world, and it puts the weights, the code, and the control in your hands. At the center of the model is LTX-2.5, a 22B-parameter dual-stream diffusion transformer that produces native 4K video at up to 50 frames per second, with audio and video generated together in a single pass rather than stitched together afterward. Artificial Analysis, an independent benchmarking group, currently ranks LTX among the top three AI video models in the world. You choose how you want to use it. Download the open weights and run LTX-2.5 on your own hardware. License the model for on-premise deployment backed by enterprise support. Or build directly on LTX Studio, the production suite that turns the model into a full creative workflow. Companies like ElevenLabs, Asteria Film Co., Magnopus, and NVIDIA already rely on LTX for their own work. LTX is not built for one-off social clips. It is infrastructure for teams that generate motion, audio, and physical environments as part of their own products and pipelines.

Dragonfly
Dragonfly serves as a seamless substitute for Redis, offering enhanced performance while reducing costs. It is specifically engineered to harness the capabilities of contemporary cloud infrastructure, catering to the data requirements of today’s applications, thereby liberating developers from the constraints posed by conventional in-memory data solutions. Legacy software cannot fully exploit the advantages of modern cloud technology. With its optimization for cloud environments, Dragonfly achieves an impressive 25 times more throughput and reduces snapshotting latency by 12 times compared to older in-memory data solutions like Redis, making it easier to provide the immediate responses that users demand. The traditional single-threaded architecture of Redis leads to high expenses when scaling workloads. In contrast, Dragonfly is significantly more efficient in both computation and memory usage, potentially reducing infrastructure expenses by up to 80%. Initially, Dragonfly scales vertically, only transitioning to clustering when absolutely necessary at a very high scale, which simplifies the operational framework and enhances system reliability. Consequently, developers can focus more on innovation rather than infrastructure management.

Jscrambler
Jscrambler is the leader in Client-Side Security, protecting the code, data, and digital interactions that power today’s modern web applications. Modern applications are changing rapidly as development teams adopt AI-generated code, rely on third-party software components, and embed AI-powered agents into digital experiences. Meanwhile, sensitive information is increasingly created and processed in the browser itself. This creates a critical gap in enterprise security: organizations need to govern not only what code enters an application, but how that code, scripts, and data behave when the application runs. Jscrambler closes that gap with a Client-Side Security Platform built around its Behavioral Enforcement Core. The platform continuously monitors and enforces how application code, including AI-generated code, third-party scripts, AI agents, and sensitive data behave in the browser. By enforcing software integrity and data governance at runtime, Jscrambler gives organizations control at the point where code executes and data is created—before sensitive information can be exposed or transmitted. Organizations across retail, financial services, travel, healthcare, and other industries use Jscrambler to detect and stop client-side attacks, protect against risks introduced by AI-developed and third-party code, control AI-driven data flows, and strengthen compliance with requirements including PCI DSS, GDPR, HIPAA, CIPA, CCPA, and the EU AI Act.
