LTX-2.3

Self-Hostable

Category: video • Released 2026

22B open-weight audio-video model with text, image and synchronized audio workflows

LTX-2.3 weights use the LTX-2 Community License Agreement. Local use needs large weights, a compatible pipeline, CUDA/PyTorch and a separate Gemma text encoder; hosted API access is separately priced.

Pricing Structure & Model AccessOpen weights under LTX-2 Community License, not Apache/MIT. Hosted API usage is separate.

Free Access QuotaWeights available under community terms; review commercial-use and restriction clauses.

Free Tier Limits22B weights are very large (about 46 GB per full/distilled checkpoint file); local GPU memory depends on inference setup.
