LTX VIDEO 2.3 · LORA TRAINER
Drop in a folder of clips. Grix captions them, runs a Train LTX job on fal.ai, and hands you back a LoRA that drops into any LTXV endpoint — fast or quality, start-end frame, reference video, lip sync.
From $5 · Distilled + full · Safety-checked · Never used to train public models

HOW IT WORKS
Upload 10–40 clips or a folder. Anything LTXV likes: 24 fps, 2–5 seconds, any aspect ratio. Video or image sequences both work.
A captioner tuned for LoRA work writes trigger tokens and descriptions — the kind that actually help training, not just describe frames. Every caption is editable.
Your job runs on Train LTX. Pick Fast (~$1.20) or Quality (~$5.60). Grix monitors loss in real time and tells you when to stop.
One composer bar for every LTXV feature: start/end frame, reference, lip sync, extend. Export .safetensors anytime.
THE STUDIO
Type a prompt. Pick a LoRA. Drop a start frame, an end frame, a reference video. Hit go. Fast mode is distilled, quality is full — nothing else to learn.
Open the studio →LTXV 2.3 · WHAT WE RUN
Grix uses fal's Train LTX endpoint directly — the same pipeline Lightricks ships for LTXV 2.3. That means correct bucketing, the right captioning format, and a LoRA that runs on both the distilled and full checkpoints.
Ready to move to Wan 2.2, Hunyuan Video, or LTX-2 (Lightricks' audio-video model) later? Same studio, same captioning, same exports. The endpoint changes under the hood — nothing you need to manage.
Shown for transparency — you never need to touch these. One composer handles them all.
HOW WE COMPARE
HOW WE'RE BUILDING IT
Credits map 1:1 to what the GPU actually costs us, plus a margin. No fake trial that loses money, no "contact us" enterprise tier, no surprise overages.
Most bad LoRAs are bad captions. We wrote a captioner tuned specifically for LoRA training — every caption is editable before you launch a job.
Every LoRA exports as .safetensors. Use it on fal, in ComfyUI, or anywhere LTXV 2.3 runs. Your clips are never used to train public models.
PRICING
One currency for training, testing, generating. Fast training is ~120 credits (~$1.20). Quality is ~560 credits (~$5.60).

FAQ
A hosted trainer for video LoRAs. You upload clips, Grix captions them and runs the Train LTX job on fal.ai, and you get a .safetensors LoRA that drops into LTX Video 2.3 — plus a studio to test it without ever leaving the app.
Nothing fundamental — it's the same Train LTX endpoint under the hood. Grix handles the captioning, picks sensible steps and learning rates for your use case, monitors the loss and tells you when to stop, and gives you a studio to test the LoRA the second it finishes.
LTX Video 2.3 is live (distilled and full). LTX-2 (Lightricks' audio-video model), Wan 2.2, and Hunyuan Video are on the roadmap — same studio, same captioning, same exports.
We built a captioner specifically for LoRA training — short trigger tokens plus the descriptive detail that training actually needs. You can edit every caption before kicking off a job.
Fast mode runs about 120 credits (~$1.20) for a 10-clip character LoRA — roughly 12 minutes on fal's Train LTX. Quality mode runs a longer schedule at around 560 credits (~$5.60). You set a credit cap; Grix monitors loss and stops early if it has converged.
Yes. Every completed job has a .safetensors download. Use it on fal, on ComfyUI, or anywhere LTXV 2.3 is supported.
The $5 starter pack gives you roughly one Fast training job and some studio time. You keep the LoRA regardless. There is no time-limited free trial that locks you out.
$5 starter pack covers your first fast training job. Keep the LoRA regardless.
