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.

Azore is software for computational fluid dynamics. It analyzes fluid flow and heat transfers. CFD allows engineers and scientists to analyze a wide range of fluid mechanics problems, thermal and chemical problems numerically using a computer. Azore can simulate a wide range of fluid dynamics situations, including air, liquids, gases, and particulate-laden flow. Azore is commonly used to model the flow of liquids through a piping or evaluate water velocity profiles around submerged items. Azore can also analyze the flow of gases or air, such as simulating ambient air velocity profiles as they pass around buildings, or investigating the flow, heat transfer, and mechanical equipment inside a room. Azore CFD is able to simulate virtually any incompressible fluid flow model. This includes problems involving conjugate heat transfer, species transport, and steady-state or transient fluid flows.

HYDPRO
When drilling either a vertical or extended-reach well, maintaining an appropriate equivalent circulating density (ECD) is essential, as deviations from the optimal range can lead to significant drilling challenges and financial overruns. The success of a drilling operation hinges on achieving the right ECD, making precise modeling and enhanced drilling hydraulics vital. This approach not only facilitates proactive planning for engineers but also boosts drilling efficiency, mitigates risks, and minimizes non-productive time (NPT). Pegasus Vertex's HYDPRO stands out as an all-encompassing drilling hydraulics model, addressing every facet of hydraulics such as downhole circulating pressures, surge and swab effects, ECD management, bit optimization, hole cleaning, and volumetric displacements. By utilizing these capabilities, engineers can thoroughly analyze downhole hydraulic conditions and pinpoint potential issues before they arise during field operations. Consequently, the implementation of such advanced technology is instrumental in ensuring the overall success and cost-effectiveness of drilling projects.
