FAQ

LTX 2.3 Fast FAQ

Common questions about Lightricks' open-weights speed model

What is LTX 2.3 Fast?

LTX 2.3 Fast is Lightricks' open-weights AI video model, released in March 2026. It offers the fastest iteration loop in its class, is capable of 1080p output, and costs just 24 credits per generation - ideal for creators who iterate heavily.

How does LTX 2.3 Fast compare to LTX 2.0 and the old LTX Fast Video?

LTX 2.3 Fast is a clear upgrade over both LTX 2.0 and the original LTX Fast Video. Generation speed is noticeably quicker, motion quality and prompt adherence are improved, and 1080p output is now within reach. If you found LTX 2.0 promising but rough, 2.3 Fast is where the line matures.

What does 'open weights' mean for me?

Open weights means Lightricks publishes the model parameters publicly. The community can audit, fine-tune, and build on the model, which drives rapid improvement and transparency - and it's a big reason the LTX ecosystem evolves so quickly.

How much does LTX 2.3 Fast cost?

Each LTX 2.3 Fast generation costs only 24 credits, making it one of our most affordable video models. Combined with its speed, you can run many more experiments per credit than with heavier models.

Can LTX 2.3 Fast really do 1080p?

Yes. While the 'Fast' name emphasizes speed, LTX 2.3 Fast is 1080p capable. Use quick lower-resolution passes to explore ideas, then render your chosen concept at Full HD.

Should I wait for LTX 2.5 instead?

LTX 2.5 is emerging, but LTX 2.3 Fast is available right now at just 24 credits with proven speed and quality. For current projects, 2.3 Fast is the practical choice - and anything you learn prompting it carries over to future LTX releases.
