LTX API
Turn text, images, or audio into 4K video with synchronized sound: up to 50% less cost per second and up to 30× faster at scale.

Quickstart
Authenticate with a bearer token and POST a prompt. The API returns an MP4. Use the sync endpoint for quick clips, or the async job API for production workloads.
Pricing
Enter your monthly volume and average video length.

Why build on LTX
Choose speed or fidelity on the same API: Fast tier for iteration, Pro tier for final renders.
Sync and async APIs with documented rate limits, so heavier jobs run without long-lived connections.
One REST API, clear documentation, and a public API changelog to track every change.
A public status page with live availability and incident history.
The certifications and contractual guarantees your security and legal teams ask about. All standard, before you write a line of integration code.
Audited controls for security, availability, and confidentiality.
Certified information security management system.
Certified AI management system.
Compliant with EU and California privacy law.
Stored data is encrypted.
Available for enterprise contracts.
Product and Platform
Delivered as an IC-LoRA on LTX-2.3. Generate directly in HDR or convert existing SDR footage to EXR. More grading latitude, more range, ready for real finishing pipelines.

Regenerate just one section — replace video, audio, or both — without re-rendering the whole clip.

Repurpose a video to any aspect ratio for social, filling new areas with generated content.

Generate video where voice, music, and sound effects define structure, pacing, and motion.Built for production-grade workflows that require precise, harmonious control over audio-led scenes - from podcasts and avatars to voice-driven clips -not one-off demos or talking heads.

Low-cost, high-speed generation for rapid iteration, storyboards, and previews.
Technical characteristics:
Higher detail and motion stability for final, commercial-grade renders.

Customer Voices
"LTX is a driving force in AI video, so when the opportunity came up to work together, it felt like a no-brainer. Audio driving video, where sound becomes the control layer is the first of its kind in AI video generation. So when we launched LTX's model within ElevenCreative and saw such a notable volume in video generations, it wasn't a surprise. Creators were ready, they just needed the tools to catch up."
”AI laddered up to [the creative idea] perfectly, and the client was stoked that we were doing this partnership. We could create marketing materials for them that did not harm or put the animals under any stress at all. We weren’t filming the animals, we weren’t going there with lights and crew and putting the animals under stress.”
"At the very end, the creative changed and evolved and improved a lot with the tools that we had for creating new scenes, and created different angles, even with the prompts, we were getting different scenes, different sequences that we were able to adjust the creative and actually improve ideas."
“LTX's HDR IC-LoRA gives our compositors and colorists the latitude to truly blend these elements rather than just stack them. We're applying it across our generative animation and augmented crowds, and the line between what's generated and what's traditionally rendered disappears.”
"When editing AI-generated shots, the final edit always looks off, different contrast, values, color balance from shot to shot. We try to unify it in post, but 8-bit SDR leaves almost no latitude for color correction."
"The industry has long needed a bridge between generative AI and professional finishing standards. By moving past 8-bit SDR, we’ve eliminated the technical gap that kept AI assets from being used on high-fidelity displays and within complex spatial experiences. We’re no longer compromising on bit depth; we’re finally getting the dynamic range required for cinematic immersion in XR and virtual production. In the past, AI-generated content was a black box; you couldn't relight it or grade it without the image falling apart. Now, these assets behave like the real world, carrying the dynamic range needed to sit alongside traditionally captured elements. This gives our teams a professional-grade toolkit to integrate generative AI into their creative process."
