You get full control over your AI: run LTX locally on your own hardware, fine tune it on your own IP, and generate video and audio as one unified output instead of stitching together separate tools. The latest model, LTX-2.5, is a 22B-parameter dual-stream diffusion transformer that generates native 4K video at up to 50fps, with synchronized audio and video produced in a single pass. Weights, code, and research are fully open, and independent benchmarking from Artificial Analysis ranks LTX among the top 3 AI video models globally. Access LTX three ways: download the open weights and run it yourself, license the model for on-premise deployment with enterprise support, or build on LTX Studio, the production suite for creative teams and studios. Teams at ElevenLabs, Asteria Film Co., Magnopus, and NVIDIA already build on LTX. LTX is production infrastructure for AI teams generating motion and physical environments inside their own pipelines, not a consumer app for one-off clips. 182 Ratings Visit Website Codemagic Codemagic macOS build machines make building hybrid applications seamless thanks to the ever-growing list of preinstalled software available.

AI has changed how every company works, and how every company gets attacked. Employees use AI tools IT doesn't know about. Attackers craft deepfakes, vishing calls, and spear phishing emails that get past filters. Adaptive addresses all of it in one unified platform: managing AI tool usage before it becomes a liability, training employees on the threats they'll actually face, simulating AI-powered attacks, and protecting the inbox and browser so threats never reach their intended targets. Because it's one platform, Adaptive develops a complete risk picture and uses it automatically, applying targeted training, attack simulations, and policy controls to lower risk over time. More than 1,000 organizations run Adaptive to manage their human security program, having raised $150M+ from NVIDIA, Andreessen Horowitz, Bain Capital Ventures, and Citi Ventures. 91 Ratings Visit Website

Pros & Cons from Real Users Pros Comsol allows for creating physics simulations in a large variety of fields (from acoustics, to electromagnetics, to thermal applications, to fluid dynamics, to semiconductor physics, to.... you name them). The overall capabilities of Comsol Mutiphysics are pretty much endless as soon as you have to solve differential equations. Its GUI is really nice and is more intuitive than some other alternatives such as Abaqus. Cons At first it can be very intimidating and overwhelming. Deciding what "physics" you want to solve, setting up your first simulation, customizing your equations, calculating specific physical quantities, testing for convergence, ... This is true for most of the specialized software, but because of the multiphysics component, it can be daunting to get started with this particular software suite. To me, the most negative aspect is the customer support. I've been conducting research in my field for over 15 years and I've used multitude of software, from open source to commercial packages, and Comsol has the worst technical support of them all. Several years ago, I interviewed for a senior application engineer position at Comsol, and I was told by the senior managing engineer who was interviewing me two things that made me reject the offer they made: 1) that the company "does not care about academia because academic license are cheap and do not bring in money" (as opposed to industry) and 2) "Engineers at Comsol are not suppose to help people with their particular technical problems, they are here to refer the customer to online resource that already exist".
