LTX 2.5 on Mac: Local AI Video with Lekh AI Pro (2026)

LTX 2.5 on Mac runs inside Lekh AI Pro, so you can turn a text prompt or a photo into a video with sound without uploading anything to the cloud. Most LTX 2.5 setups are built for NVIDIA graphics cards and need a terminal. Lekh AI Pro packs the model into a native app for Apple Silicon. You get text-to-video and image-to-video in one place, next to a full local AI studio. The sections below cover what the model does, what your Mac needs, and who it suits best.

What Is LTX 2.5?

LTX 2.5 is an open-weight video model from Lightricks that creates video and synchronized audio from text, images, or existing video. The license is dated 11 August 2026, and the model has 22 billion parameters. Four upgrades matter most for everyday users, per Lightricks' own release notes:

• Native multi-shot generation: One prompt can create several shots that keep the same characters, setting, and lighting.

• A new diffusion video decoder: It aims for cleaner motion and sharper detail.

• A Gemma 4 12B text encoder: The model follows detailed directions more closely.

• Optional automatic duration: The model can estimate how long a clip should run.

The license is free for companies under 10 million dollars in annual revenue, so check the official terms if you sell what you make. Lekh AI already runs more than 1,000 local AI models on a Mac, and LTX 2.5 adds video to that list.

LTX 2.5 on Mac With Lekh AI Pro

Lekh AI Pro runs LTX 2.5 on your Mac for both text-to-video and image-to-video, with synchronized audio and output up to 1024×768. Everything runs on your device, and local workflows need no cloud account or API keys. The video studio sits beside Flux image generation, ACE Step music generation, local chat, and speech tools, so one app covers a full creative workflow. Lekh AI Pro also lists tool calling, an agentic browser, and a coding agent in beta, so the same purchase covers work beyond video.

The model itself can reach much higher resolutions. The model card names up to 3840×2176. Lekh AI Pro currently lists up to 1024×768, so plan on that for now.

Lekh AI Pro is a one-time purchase with no subscription. It is a direct download rather than an App Store release, and Flux models are not in the App Store version. LTX 2.5 video is listed as a Pro feature. Lekh AI is a local AI app for Mac, and the Pro version adds the video tools. Pro also unlocks Flux image generation for stills you can animate later.

How to Use LTX 2.5 Text to Video and Image to Video on Mac

For text to video, describe the scene you want. For image to video, start with a photo and describe how it should move.

1. Install Lekh AI Pro on an Apple Silicon Mac running macOS 15 or later.

2. Open the video studio.

3. Choose text to video or image to video.

4. Write your prompt, or add your source image.

5. Generate the clip, review it, and adjust the prompt.

Prompt tips that help

• Name the subject first, then the setting.

• Ask for one clear motion, such as a slow walk or drifting smoke.

• Add a camera move, such as a slow push in.

• Describe the sound you want, since the model makes audio too.

What image-to-video is best for

Image-to-video works well for portraits, product photos, and artwork. Lekh AI's own demo turns a still illustration into a moving clip, all on the Mac. A clean source image with a clear subject usually gives the model more to work with, and your photos stay on your own machine. For more tools in this space, see the guide to image-to-video options.

What Can You Make With LTX 2.5 on Mac?

LTX 2.5 on Mac works best for short, focused clips where you control the idea and the look. Common uses include social posts, product shots that come to life, animated artwork, storyboard tests, and background footage for a project. Multi-shot support helps when one idea needs a few angles, such as a wide view followed by a close-up of the same character.

A simple workflow helps most people. Create a still with Flux, then use image to video to bring that still to life. Because both steps run in the same app, the image never leaves your Mac, and you do not move files between tools. Each pass runs on your own Mac, with no subscription.

What Mac Do You Need for LTX 2.5?

Lekh AI Pro needs a Mac with Apple Silicon, from M1 to M5, running macOS 15 or later. The listed minimum is 8 GB of RAM, with 16 GB recommended for larger models. The app takes 1.6 GB of storage, plus room for the models you download.

Those are app-wide specs. Lekh AI has not published RAM or clip length limits for LTX 2.5 alone, so treat video as the heaviest job your Mac will do. Open-source Mac ports of the model recommend 32 GB or more, or 16 GB with a memory-saving mode. More unified memory gives you more headroom, and a short first clip is a safe way to test your machine. Read how much RAM local AI needs and the full local AI hardware requirements before you choose a Mac for video work.

Why LTX 2.5 on Mac Is Hard to Set Up Yourself

Setting up LTX 2.5 on a Mac manually requires Python, large downloads, and patience. Community Mac ports run on Apple's MLX framework and start from a terminal. Some users report black videos or save errors with standard workflows on Apple Silicon. Others report decoder errors on M5 and M2 Ultra Macs, which one user traced to a number type Apple's graphics layer does not support.

An app that ships the model already set up skips that work. If you only want to compare options first, the roundup of local video generation tools shows the wider field.

Is LTX 2.5 on Mac Private?

Yes. In Lekh AI Pro, LTX 2.5 runs on your Mac, and Lekh AI states that no data leaves your device. Your prompts, source photos, and finished videos stay on your machine. That matters for client work, family photos, and unreleased product shots. You can read more about on-device AI privacy and the wider set of offline AI tools in the app.

Who Should Use LTX 2.5 on Mac?

Lekh AI Pro suits creators who want video without a monthly fee, anyone working with private photos or client assets, and people who want video, images, music, and chat in a single app.

It is not the right pick if you need 4K output today, or if you want video on your phone. Lekh AI Pro is Mac-only.
