About
LTX2.3 Audio Reactive LoRA LoRA adapter for LTX-2.3 audio-reactive video generation. V2 Update - June 15, 2026 V2 adds stronger audio-reactive motion, heavier beat impact, and more aggressive smoke/liquid-light movement driven by the track. This update focuses on making the LoRA feel more responsive to music: faster visual hits, sharper bass pressure, stronger particle flicker, and smoother motion for music-video presentation. LTX2.3 Audio Reactive LoRA is a LoRA adapter for LTX-2.3 designed to make video generation react more visibly to music and sound. It focuses on beat-locked visual motion: cubic forms, particles, light pulses, camera pushes, graphic texture, and material deformation moving in sync with kicks, bass, snares, hi-hats, and synth changes. The LoRA is intended for audio-to-video and image-plus-audio-to-video workflows, especially with the fal.ai endpoint fal-ai/ltx-2.3-quality/audio-to-video/lora.

Using it via the API
Once AxForge deploys ltx2-3-audio-reactive-lora for you, it answers on the OpenAI-compatible API — the same base URL and keys as every other model. (ltx2-3-audio-reactive-lora below is illustrative; you get the exact model name on deployment.)
$ curl -sS https://api.axforge.ai/v1/videos/generations \
-H "Authorization: Bearer $AXFORGE_API_KEY" \
-H "Content-Type: application/json" \
-d '{"model":"ltx2-3-audio-reactive-lora","prompt":"a drone shot over a forest"}'

Licence
The weights are open but its licence needs a commercial agreement for business use. AxForge can arrange that licence and host the model for you — you pay AxForge, we settle with the model’s maker. Ask us for a quote. Read the licence ↗
