What Is LTX 2.3?
LTX 2.3 is the latest release from Lightricks, built on a DiT (Diffusion Transformer) architecture. You can try LTX 2.3 online at LTX23.org to experience its capabilities firsthand. It is a single foundation model that generates both synchronized video and audio in one diffusion pass — a unique capability in the open-source landscape.
Key highlights of LTX 2.3 include:
- Rebuilt VAE: Trained on higher-quality data, producing sharper fine textures — hair, text, and edge details are preserved even at 4K.
- 4× larger text connector: Complex prompts with multiple subjects, spatial relationships, and stylistic instructions now resolve much more accurately.
- Native portrait video: Generate vertical 1080×1920 content trained on portrait-orientation data, not cropped from landscape.
- Cleaner audio: Filtered training data and a new vocoder reduce artifacts and improve alignment.
- Stronger Image-to-Video: Less freezing, less "Ken Burns slow pan" artifacts, and better visual consistency from the input frame.
LTX 2.3 supports text-to-video, image-to-video, audio-to-video, video-extend, and retake-video workflows — all within the same model. It offers two generation flows: Fast Flow (prioritizing speed and iteration) and Pro Flow (prioritizing maximum visual quality).
Model checkpoints available: Full dev (bf16), distilled (8 steps, CFG=1), fp8 quantized, spatial upscaler (×1.5, ×2), and temporal upscaler (×2).

What Is Wan 2.2?
Wan 2.2 is developed by Alibaba's Tongyi Lab and built on a 27B Mixture-of-Experts (MoE) diffusion architecture. Instead of routing all computation through a single network, Wan 2.2 uses specialized "experts" — a high-noise expert for structural layout and a low-noise expert for textures, lighting, and fine details.
Key highlights of Wan 2.2 include:
- MoE efficiency: Allocates compute dynamically — focusing on broad structure first, fine details later — boosting quality without proportionally increasing cost.
- Cinematic quality: Excels at complex camera motion, narrative composition, and film-grade lighting that rivals closed-source models.
- Strong prompt fidelity: Among the best at faithfully translating complex natural language instructions into visual output.
- Massive training data: +65.6% image data and +83.2% video data compared to previous versions, dramatically improving generalization.
Wan 2.2 ships in three main variants:
- T2V (Text-to-Video): 480p–720p clips from text prompts
- I2V (Image-to-Video): Animate a single image into video, with optional text guidance
- Hybrid / TI2V-5B: A compact 5B-parameter model for both T2V and I2V at 720p@24fps on consumer GPUs
Architecture: DiT vs. MoE — How They Differ
Understanding the architectural difference is key to understanding the LTX 2.3 vs Wan 2.2 trade-offs.
LTX 2.3: Latent Diffusion Transformer
LTX 2.3 operates in a compressed latent space — the model first generates a compact representation of the video, then decodes it back to full resolution via the rebuilt VAE. This approach:
- Makes high-resolution (up to 4K) generation feasible without extreme memory requirements
- Enables faster iteration cycles — ideal for interactive creative tools
- Allows simultaneous audio generation in the same latent pass
The 4× larger gated attention text connector in version 2.3 is a major upgrade: it bridges the language model's understanding and the visual generation much more tightly, so prompts with multiple subjects, timing instructions, and stylistic cues are rendered far more faithfully than in LTX 2.0.
Wan 2.2: Mixture-of-Experts Diffusion
Wan 2.2 uses a 27-billion parameter MoE model that splits the denoising process into specialized experts:
- High-noise expert: Handles the early stages — overall structure, composition, and motion planning
- Low-noise expert: Handles the later stages — textures, lighting, color grading, and fine detail
This division lets the model scale capacity without linearly scaling compute, resulting in:
- Superior motion coherence and complex camera movements
- Better preservation of scene intent across frames
- Especially strong performance on cinematic, narrative-driven scenes
The trade-off: Wan 2.2's approach prioritizes structured, deliberate generation. It tends to be slower per step but delivers more polished results with fewer retries on complex prompts.
Resolution, Duration & Visual Quality
This is where the LTX 2.3 vs Wan 2.2 gap is most visible.
LTX 2.3: 4K, 20 Seconds, Multi-FPS
| Spec | LTX 2.3 |
|---|---|
| Resolutions | 1080p, 1440p, 4K |
| Frame rates | 24 / 25 / 48 / 50 fps |
| Max duration | ~20 seconds per clip |
| Extension | Video-extend endpoint for longer sequences |
| Portrait | Native 1080×1920 (9:16) |
LTX 2.3's rebuilt VAE makes a real difference: fine details like hair strands, on-screen text, small objects, and edge boundaries stay sharp even at 4K — reducing the need for external super-resolution post-processing.
Wan 2.2: 720p, 5 Seconds, Cinematic Focus
| Spec | Wan 2.2 |
|---|---|
| Resolutions | 480p – 720p (primary) |
| Frame rates | 24 fps |
| Max duration | ~5 seconds per clip |
| VAE compression | 16×16×4 (total 64× compression) |
| Consumer model | TI2V-5B at 720p@24fps |
Wan 2.2's strength isn't in raw resolution or duration — it's in how those 5 seconds look. The MoE architecture delivers exceptional motion coherence, cinematic camera movements, and film-grade color and lighting that many creators consider best-in-class among open-source models.
Native Audio: LTX 2.3's Unique Advantage
One of the most significant differentiators in the LTX 2.3 vs Wan 2.2 comparison is native audio generation.
LTX 2.3 generates synchronized audio and video in a single diffusion pass. This means:
- Dialogue lip-syncs with character movement
- Environmental sounds match scene context
- Music and sound effects align with on-screen action
- No post-processing audio alignment needed
This makes LTX 2.3 ideal for:
- Character dialogue and talking-head videos
- Product demos with voiceover
- Short-form content that needs to be publish-ready without a separate audio pipeline
Wan 2.2 generates video only — no native audio output. For audio, you'd need external tools (TTS, music generation, or manual scoring). Wan 2.2 does offer a Speech-to-Video (S2V) variant that takes a static image + speech input to generate lip-synced video, but this is a separate specialized model, not part of the core T2V/I2V pipeline.
Bottom line: If your workflow requires audio-visual content in one step, LTX 2.3 is the clear winner. If you always add audio in post-production anyway, this advantage matters less.
Image-to-Video Quality
Both models support I2V (Image-to-Video), but they approach it differently.
LTX 2.3 made significant improvements in version 2.3 specifically targeting I2V weaknesses:
- Reduced "freezing" artifacts where the image barely moves
- Eliminated the "Ken Burns effect" (slow pan/zoom as a substitute for real motion)
- Better visual consistency — the generated video maintains the style, colors, and details of the input image
Wan 2.2 I2V includes an automatic prompt derivation feature — it can generate video from an image without any text input at all. When combined with text prompts, it produces well-directed results with strong motion coherence. The 14B I2V model excels at preserving the compositional intent of the source image.
Verdict: LTX 2.3 has closed the I2V gap significantly with version 2.3. For motion quality and camera control from a source image, Wan 2.2 still has an edge. For I2V with synchronized audio, LTX 2.3 is unmatched.
Inference Speed & Performance
Speed is a critical factor for production workflows, and here the LTX 2.3 vs Wan 2.2 difference is dramatic.
LTX 2.3: Built for Speed
- ~1.22 seconds per step on H100 — approximately 18× faster than Wan 2.2-14B
- Fast Flow variant sacrifices some detail for even quicker generation, ideal for A/B testing and rapid iteration
- Pro Flow variant maximizes quality while still being significantly faster than competitors
- Latent diffusion design means less compute per frame
Wan 2.2: Built for Quality
- The 27B MoE model is optimized for A100–H200 server GPU clusters
- Longer generation times per clip, but each clip tends to need fewer retries
- TI2V-5B compact model runs on consumer GPUs (RTX 4090) at 720p@24fps
- Community quantized versions (GGUF) further reduce hardware requirements
For interactive platforms (online editors, real-time creative tools): LTX 2.3's speed advantage is decisive.
For batch production (generating a library of cinematic clips overnight): Wan 2.2's per-clip quality may offset longer generation times.

Prompt Adherence & Motion Quality
This is where subjective preferences play a big role in the LTX 2.3 vs Wan 2.2 choice.
Wan 2.2: The Prompt Fidelity Champion
Multiple independent reviews and community benchmarks consistently rate Wan 2.2 as one of the strongest open-source models for:
- Complex prompt faithfulness: Multi-subject scenes, specific spatial arrangements, and precise action descriptions
- Camera motion control: Dolly, pan, crane, tracking shots rendered with cinematic intent
- Aesthetic coherence: Film-grade lighting, color grading, and compositional balance
Some comparisons have found Wan 2.2 outperforms even newer models (including Wan 2.5 in certain scenarios) on prompt fidelity — a testament to its well-trained MoE architecture.
LTX 2.3: Closing the Gap
LTX 2.3's 4× larger text connector is a direct response to the prompt adherence challenge:
- Complex prompts with multiple subjects and spatial instructions resolve more accurately
- Timing, motion, and expression descriptions translate more faithfully
- The improvement from LTX 2.0 → 2.3 is described as "generational" by the dev team
However, for the most demanding cinematic prompts — especially those involving complex coordinated camera and subject motion — Wan 2.2 still holds an edge according to community feedback.
