SANA-Sprint (local)

SANA-Sprint is NVIDIA/MIT HAN Lab’s distilled flow-matching T2I model: 1–4 steps at 1024×1024 with strong speed/quality tradeoffs. OpenTryOn exposes sana-sprint on generate (Path B, extra="local").

Requirements​

pip install opentryon[local]
pip install "git+https://github.com/huggingface/diffusers"

Default weights: Efficient-Large-Model/Sana_Sprint_1.6B_1024px_diffusers. Override with SANA_SPRINT_MODEL_ID.

CLI​

opentryon generate --model sana-sprint \
  --prompt "Editorial fashion still, soft window light" \
  --steps 2 --width 1024 --height 1024

opentryon generate --model sana-sprint --prompt "test" --dry-run

MCP​

Restart MCP after registry changes. Tool: generate_sana_sprint.

Notes​

  • No first-party hosted API in OpenTryOn — local only (integrate-next listed SANA-Sprint as Path B next).
  • For cloud T2I, use existing registry models (FLUX, Nano Banana, Seedream, etc.).
