Production Diffusion Pipelines at Dashtoon

Flux LoRA adapters for 20+ characters, Hidream-l1 MoE integration, Bollywood bias mitigation, and Google Veo 2 evaluation

As a Research Engineer at Dashtoon (Mar 2025 – Aug 2025), I built and shipped production-grade diffusion pipelines for animated character generation at 2048 resolution, spanning LoRA training, model integration, dataset curation, and video generation evaluation.

Flux LoRA Adapters

  • Trained and shipped Flux LoRA adapters for 20+ characters across 8 animation styles
  • Production inference optimized with FP16, batching, and caching, validated at 2048 resolution
  • Improved character consistency, prompt alignment, and style fidelity across a diverse cast

Hidream-l1 (MoE) Integration

  • Integrated Hidream-l1, a Mixture-of-Experts diffusion model, into the animated character pipeline during early development
  • Adapted inference and post-processing to deliver smoother 2048 resolution outputs with improved prompt alignment
  • Hardened pipeline reliability around high-resolution generation, model switching, and output consistency

Regional Bias Mitigation Dataset

  • Built a targeted dataset of 10,000+ images from 100+ Bollywood movies via automated extraction pipeline
  • Goal: reduce regional bias in image generation for South Asian character representation
  • Pipeline covered automated clip extraction, frame selection, quality filtering, and metadata tagging

Google Veo 2 & Frameo AI

  • Worked hands-on with Google Veo 2 during early access/POC to evaluate video generation quality and workflow fit for character animation
  • Partnered with the GCP team to integrate the Veo 2 workflow into the new Frameo AI platform, aligning API usage, input/output formats, and reliability requirements for production
