Abstract: We introduce TurboDiffusion, a video generation acceleration framework that can speed up end-to-end diffusion generation by 100-200x while maintaining video quality. TurboDiffusion mainly relies on several components for acceleration: (1) Attention acceleration: TurboDiffusion uses low-bit SageAttention and trainable Sparse-Linear Attention (SLA) to speed up attention computation. (2) Step distillation: TurboDiffusion adopts rCM for efficient step distillation. (3) W8A8 quantization: TurboDiffusion quantizes model parameters and activations to 8 bits to accelerate linear layers and compress the model. In addition, TurboDiffusion incorporates several other engineering optimizations. We conduct experiments on the Wan2.2-I2V-14B-720P, Wan2.1-T2V-1.3B-480P, Wan2.1-T2V-14B-720P, and Wan2.1-T2V-14B-480P models. Experimental results show that TurboDiffusion achieves 100-200x speedup for video generation even on a single RTX 5090 GPU, while maintaining comparable video quality. The GitHub repository, which includes model checkpoints and easy-to-use code, is available at https://github.com/thu-ml/TurboDiffusion.

TurboDiffusion: 100–200× Acceleration for Video Diffusion Models
Introduction
TurboDiffusion (2512.16093) presents a highly optimized framework for end-to-end acceleration of video generation using diffusion models, achieving a speedup of 100–200× compared to standard implementations while preserving perceptual video quality. The approach combines algorithmic and systems-level techniques: low-bit quantized SageAttention, Sparse-Linear Attention (SLA), score-regularized step distillation (rCM), and W8A8 quantization. Experiments demonstrate dramatic latency reduction on high-profile video diffusion models including Wan2.2-I2V-A14B-720P and Wan2.1-T2V-14B-720P, tested on a single RTX 5090 GPU.

Technical Contributions
Attention Acceleration
TurboDiffusion utilizes SageAttention2++ (Zhang et al., 27 May 2025), an accurate INT8 quantized version of multi-head attention, reducing both computational cost and memory bandwidth. This is further augmented with Sparse-Linear Attention (SLA) (Zhang et al., 28 Sep 2025), enabling fine-tunable structured sparsity for efficient sequence modeling. Notably, SLA operates orthogonally to tensor core acceleration, allowing cumulative throughput improvements when stacked with low-bit quantization.
Step Distillation via rCM
The framework adopts rCM (Zheng et al., 9 Oct 2025), a score-regularized continuous-time consistency method, for aggressive step distillation. The number of generation steps is reduced from 100 (typical for strong video diffusion) down to 3–4, while retaining high perceptual video quality and FVD metrics. Model weights from SLA finetuning and rCM distillation are merged to maximize both sparsity adaptation and step reduction.
W8A8 Quantization
Linear layers are quantized to INT8 precision for both parameters and activations, with block-wise granularity (128×128), leveraging CUDA and tensor cores. This halves model size and increases inference throughput in parallel with the aforementioned attention optimizations.
Additional Kernel Optimizations
LayerNorm, RMSNorm, and related operations are re-implemented using Triton and CUDA for substantial speed gains and hardware efficiency.
Training and Inference Pipeline
Training begins with a pre-trained video diffusion backbone. Full attention is replaced by SLA and finetuned. Simultaneously, rCM distillation is performed to learn models with reduced sampling steps. The parameter updates from both procedures are merged.
During inference, SLA is substituted with SageSLA for maximum efficiency, and all linear operations run in INT8. Further kernel-level optimizations are applied for LayerNorm/RMSNorm. The final pipeline executes on a single RTX 5090 GPU, with batch sizes and hardware utilization tuned for latency minimization.
Experimental Results
TurboDiffusion is benchmarked against both the original Wan implementation and FastVideo [fastvideo2024], across several model backbones. Experimental setup maintains 0.1–0.15 Top-K ratio (attention sparsity) and uses 3–4 sampling steps for best fidelity-speed tradeoff.

TurboDiffusion consistently demonstrates the minimum generation latency, outperforming both Original and FastVideo across models and resolutions, including 1.3B and 14B parameter configurations at 480P and 720P.
Implications and Future Directions
Practical Implications
TurboDiffusion’s pipeline renders video diffusion models feasible for real-time and interactive applications, extending their utility beyond research into production domains such as creative content generation, simulation, and AI-driven video editing. The reduction in inference latency and model footprint fundamentally shifts the cost-performance paradigm for large-scale generative video.
Theoretical Implications
The successful stacking of sparse attention, low-bit quantization, and step distillation without introducing substantial quality drop contradicts assumptions around the inefficiency and fidelity bottlenecks in diffusion-based video synthesis. This suggests that further system-optimized generative frameworks can reach unprecedented throughput without recourse to architectural compromises.
Future Work
Authors propose expanding TurboDiffusion to support autoregressive video diffusion, broader model families, and distributed inference pipelines. Future research might also integrate hardware-specific scheduling across GPU architectures and hybridize numerics for deployment on edge devices.
Conclusion
TurboDiffusion (2512.16093) is a comprehensive framework for accelerating video diffusion model inference by 100–200× via algorithmic, numerical, and kernel-level optimizations. Its combination of SageAttention, sparse attention, rCM step distillation, and INT8 quantization establishes new scalability standards for high-resolution, high-fidelity video generation. The codebase and model checkpoints are openly available, facilitating both reproducibility and further research on efficient generative video pipelines.

Overview
This paper introduces TurboDiffusion, a way to make AI video generators run much faster—about 100 to 200 times faster—without making the videos look worse. It focuses on speeding up “diffusion models,” which are popular AI systems that create images and videos step by step from random noise.
Objectives
The researchers wanted to:
- Make video generation super fast on one GPU (like an RTX 5090).
- Keep video quality close to the original model’s quality.
- Create a practical toolkit (with code and trained models) that others can use.
Methods and Approach
To understand the approach, it helps to know what a diffusion model does. Imagine starting with a very blurry video and “polishing” it a little at a time until it looks clear. That polishing happens in many small steps (often 50–100 or more). Each step uses big math operations, especially “attention” (which helps the model focus on the most important parts of the video) and “linear layers” (large matrix multiplications).
TurboDiffusion speeds things up by improving three major parts and tweaking a few others. Think of it like tuning a race car: lighter parts, smarter driving, and better fuel.
Here are the main techniques they used, explained with everyday analogies:
- Attention acceleration
- SageAttention (low-bit attention): Instead of always using big, precise numbers, it uses smaller 8-bit numbers where possible. This is like storing photos at a lower file size without noticeable quality loss—faster to load and process.
- Sparse-Linear Attention (SLA): Rather than looking at everything, the model focuses only on the most important parts (“Top-K”). It’s like skimming the most relevant paragraphs instead of reading the entire book. This reduces the amount of work the model does.
- Step distillation (rCM)
- Distillation teaches a “student” model to do in just a few steps what a “teacher” model does in many steps. Imagine learning shortcuts from an expert so you can finish a task in 3–4 steps instead of 100. The rCM method is a state-of-the-art way to do this well without losing quality.
- W8A8 quantization (8-bit weights and activations)
- Quantization shrinks the size of the numbers the model uses from bigger ones to 8-bit integers (INT8). It’s like packing items in smaller boxes so you can carry more and move faster. This speeds up the “linear layers” and also makes the model about half the size.
- Other engineering optimizations
- The team rewrote some parts (like LayerNorm and RMSNorm) in fast GPU languages (CUDA/Triton) to squeeze out extra speed.
Training and Inference
- Training (preparation):
- Replace full attention with SLA and finetune the original model so it learns to work with sparsity.
- At the same time, train a distilled “student” model using rCM so it can generate good videos in only 3–4 steps.
- Merge the improvements from both training processes into one model. This can use either real or synthetic (AI-made) data.
- Inference (actually making videos):
- Use a fast GPU implementation of the sparse attention (SageSLA).
- Cut the number of steps from ~100 down to 3 or 4.
- Run linear layers with INT8 numbers on special GPU hardware (“Tensor Cores”) for a big speed boost.
- Use efficient GPU implementations for other operations.
Main Findings
TurboDiffusion achieved very large speedups while keeping video quality comparable to the original models:
- On a single RTX 5090:
- A 5-second video with a medium-size model (Wan2.1-T2V-1.3B at 480p) dropped from about 184 seconds to about 1.9 seconds.
- A 5-second video with a very large model (Wan2.2-I2V-A14B at 720p) dropped from about 4549 seconds to about 38 seconds.
- Overall, this is roughly a 100–200× speedup.
- Compared to another fast method (FastVideo), TurboDiffusion was both faster and kept quality as good or better in visual comparisons.
These results come from combining smarter algorithms (like sparse attention and step distillation) with system-level optimizations (like INT8 quantization and GPU-specific code).
Why This Matters
- Faster generation means creators can experiment more, iterate quickly, and spend less money and energy.
- It opens the door to near real-time video generation, which could help in areas like:
- Content creation and editing
- Game development and interactive media
- Education, design, and animation
- Making high-quality video generation efficient on one GPU lowers the barrier to entry—more people can use these tools without huge computing resources.
Conclusion and Impact
TurboDiffusion shows that you can dramatically speed up video diffusion models—100 to 200 times faster—without hurting quality, by combining:
- Smarter attention (only looking at the most important parts),
- Fewer, better steps (distillation),
- Smaller, faster numbers (8-bit quantization),
- And optimized GPU code.
This approach could influence future research and commercial tools for video, images, and even other media generated by diffusion models. It makes advanced AI video generation more practical, cheaper, and more accessible for everyone.
Knowledge Gaps
Below is a concise, actionable list of the paper’s unresolved knowledge gaps, limitations, and open questions that future work could address:
- Quantitative quality evaluation is missing: no FVD/FVD-k, LPIPS, CLIP-based metrics, temporal consistency (e.g., tLPIPS), or human preference studies to substantiate “maintaining video quality.”
- Absence of a systematic failure analysis: no documented cases where sparse attention, low-bit attention, or W8A8 quantization degrades quality (e.g., flicker, motion jitter, fine textures, faces, text legibility).
- Limited resolution and duration scope: evaluations focus on 480p/720p and ~5-second clips; impact on 1080p/4K, higher frame rates, longer videos (30–120s+), and wide aspect ratios is unexplored.
- Generalization across model families: results are only on Wan-series video diffusion models; applicability to other architectures (e.g., Stable Video Diffusion, SVD-XT, Gen-3, 3D U-Nets with different attention layouts) is untested.
- End-to-end latency exclusion: reported speedups exclude text encoding and VAE decoding; the overall user-perceived latency and potential bottlenecks in these stages remain unquantified and unoptimized.
- Hardware portability and reproducibility: speedups are primarily on RTX 5090; quantitative results on H100, 4090, A100, consumer laptops, mobile/edge devices (Apple, AMD, Intel ARC) and CPU-only environments are missing.
- Batch-size and throughput trade-offs: no analysis of how speedups scale with batch size, concurrent requests, or multi-stream inference in production settings.
- Multi-GPU scaling: the paper lacks evaluation of data/model parallelism, pipeline parallel strategies, and interconnect-induced overheads for larger batch or higher-resolution generation.
- Energy efficiency and cost: power consumption, energy-per-video, and cost-per-video are not reported; efficiency trade-offs across hardware are unclear.
- rCM step-distillation details: training recipe (losses, schedules, teacher-student setup, noise schedules), compute cost, convergence behavior, and robustness across prompts/domains are unspecified.
- Parameter merge methodology: how SLA finetuning updates and rCM distillation weights are merged (e.g., weighted averaging, layer-wise merges) and potential conflicts/instabilities are not described or ablated.
- Adaptive sparsity policies: Top-K is fixed (0.1–0.15); there is no investigation of layer-wise, head-wise, or time-step-adaptive sparsity schedules and their impact on quality/speed.
- Attention sparsity sensitivity: no sensitivity analyses relating sparsity to different prompt types (complex compositional scenes, camera motion, multi-object interactions) or sequence lengths.
- SageSLA vs SLA parity: the numerical and qualitative equivalence between training-time SLA and inference-time SageSLA kernels is not validated; potential kernel-induced drift is unexamined.
- Component-wise ablation: while a decomposition figure is shown, there is no detailed quantitative breakdown of each component’s contribution (SageAttention, SLA, rCM, W8A8, Triton/CUDA norms) on latency and quality.
- Quantization scope and strategy: only Linear layers are W8A8; effects of quantizing attention projections, convolutions, residual blocks, or cross-attention are not studied; layer-wise granularity or mixed-precision policies remain open.
- Post-training vs QAT: the paper does not clarify whether quantization-aware training or calibration is used; robustness of INT8 activation quantization under diverse content and long sequences is unknown.
- Block size choice: the rationale and sensitivity for the 128×128 block-wise granularity in INT8 quantization (per-layer/per-head optimality, small-layer behavior) is not evaluated.
- Temporal consistency under acceleration: explicit temporal metrics (e.g., optical flow consistency, temporal FVD) are missing; impact of 3–4 step sampling on motion coherence is unquantified.
- I2V dual-model overhead: the switching overhead between high-noise and low-noise models is acknowledged but not mitigated; techniques to unify or amortize the switch are not explored.
- Robustness to domain shifts: training claims to use real or synthetic data; there is no study of domain generalization (e.g., cartoons, low-light, fast action, egocentric footage).
- Prompt robustness and controllability: performance on complex prompts (camera paths, scene layout constraints, story consistency), and compatibility with control signals (ControlNet, keyframes) are untested.
- Personalization and adapters: compatibility and quality with LoRA, DreamBooth, or fine-tuned adapters under sparse/quantized attention and W8A8 linear layers is unknown.
- Determinism and stability: the effect of low-bit kernels and sparsity on output determinism across runs, driver versions, and kernel configurations is unreported.
- Integration with other samplers: interoperability with alternative fast samplers and distillation methods (e.g., progressive distillation, consistency models, FreeNoise) is not evaluated.
- VAE/decoder acceleration: no methods are proposed to speed up VAE decoding or video post-processing, despite their contribution to wall-clock time in practical pipelines.
- Memory footprint and capacity: VRAM savings and maximum video length/resolution achievable due to quantization are not quantified; memory fragmentation and allocator behavior with custom kernels are unaddressed.
- Safety and robustness: no analysis of adversarial or pathological prompts that may exacerbate artifacts under sparse/low-bit attention; mitigation strategies are absent.
- Licensing and model access constraints: practical reproducibility is unclear if Wan checkpoints or required assets are restricted; portability of TurboDiffusion to open-weight models is not demonstrated.
