ScenemaAI just open-sourced Scenema Audio, an expressive speech model extracted from the LTX 2.3 audiovisual transformer. It lets you direct emotional shifts and ambient background noise using stage-direction action tags, alongside zero-shot voice cloning. The model fits in 16GB VRAM and supports 13 languages.
Scenema AI just open-sourced Scenema Audio, an audio diffusion model extracted from LTX 2.3 that separates voice identity from emotional performance. Creators can use text stage directions to dictate mood, pacing, accents, and mid-sentence emotional shifts without being constrained by the reference audio. Quantized weights run locally on 16GB of VRAM.
A new 15B open-source video generator called DaVinci Magihuman just dropped, capable of natively generating video with audio across multiple languages. In self-reported blind tests, it beat LTX 2.3 60% of the time with zero censorship, though running even its distilled version requires a hefty 61GB download.
Lightricks just launched LTX-2.3, upgrading its open-source audiovisual model with sharper textures, cleaner dialogue, and native 1080x1920 portrait video. Alongside it comes LTX Desktop, a free local video editor powered by the same engine. Why it matters: Full model weights and ComfyUI workflows are live on Hugging Face, free for companies making under $10M in annual revenue.
