This looks like a strong research to production gap problem, not just model work. While my background is more on backend and system architecture rather than deep model training, I’ve worked on integrating AI services into real world applications where reliability, scalability, and clean API design matter just as much as the model itself. For a setup like this, I’d focus on structuring a stable inference pipeline, handling request concurrency, and making sure the system can scale without breaking under load. That includes designing clean API layers, managing queues for GPU workloads, and ensuring deployments are predictable and maintainable. If you already have models or pipelines in place, I can help turn them into a production ready system that’s easier to operate and extend. Happy to discuss where you are currently and what’s blocking you most.

I’ve built low-latency, high-concurrency pipelines for CogVideo-like models that served hundreds of simultaneous sessions with sub-2s cold-start and stable steady-state latency. The real bottleneck isn’t just model size but memory-bound attention and inefficient batching. Fusing attention (xformers), TensorRT kernels, and smart dynamic batching usually yields the biggest ROI before aggressive quantization. I recently took a CogVideoX-based prototype into production for a content studio, converting key kernels to TensorRT, adding xformers attention, and using LoRA for consistent character renders. My approach: quick audit of your Wan2.2 / CogVideoX checkpoints, convert and profile with TensorRT/xformers, apply mixed-precision and calibrated quantization, run controlled LoRA fine-tuning with validation to prevent drift, then expose a Python/Node.js inference API with autoscaling and metrics. I keep hyperparameter sweeps small and targeted to save time. What target throughput, latency, and GPU types are you aiming for so I can size the pipeline correctly?

I’ve worked on AI pipelines where the main challenge was not just running models, but making them efficient, scalable, and reliable under real usage. I’m comfortable working with PyTorch based systems and building inference services that can handle high concurrency without performance drops. For your requirements, here is how I would contribute: - Set up and optimize inference pipelines for image and video generation, focusing on batching, memory management, and GPU utilization - Work with models like Diffusers and DiT based architectures, and adapt them for production use - Apply performance optimizations such as quantization, xformers, and TensorRT where applicable to reduce latency and cost - Implement LoRA fine tuning for style and character consistency, with attention to avoiding overfitting and maintaining generalization - Build clean API services for inference so the models are easy to integrate into your applications I also have experience moving from experimental setups to production ready systems, which usually involves restructuring pipelines, improving observability, and making deployments repeatable. If helpful, I can share examples of similar AI workflows I’ve worked on and how I approached performance optimization. Happy to discuss your current setup and where you are seeing the biggest bottlenecks. Best, Ravisher

Hey, AI image and video pipelines under real concurrency are exactly where I spend most of my time these days. I work in Python with FastAPI for serving generative models, and I've tuned inference paths with batching, GPU pinning, and queue-based fanout when latency matters. Are you generating with diffusion models you host yourself, or are you wrapping a third-party API? Happy to jump in once that's clear.
