LoRA (Low-Rank Adaptation)
Low-Rank Adaptation – a lightweight method for fine-tuning large pretrained models (especially diffusion image models and LLMs) by injecting small trainable low-rank matrices into frozen weights, so you can specialize a model (e.g., to a character) with a tiny fraction of the parameters and compute of a full fine-tune.
LoRA is widely used to train consistent character / style adapters on image-generation models (Stable Diffusion and its forks). A LoRA trained on a character produces a reusable adapter that can be loaded into a base model at inference time to get that character’s look across poses, lighting, and eras while keeping the base model frozen.
On One Small Crawl
- 2026-04-13-frames-call – LoRA proposed to train the snail character for consistent animation across eras (first snail concept art by alberto-ciprian: 3D model, cartoonish, non-photorealistic). The plan: train a LoRA on the snail so the character looks consistent across the five-media-era sweep of the film (2026-04-13-frames-call).
- 2026-05-11-frames-call – LoRA models for snail ages were done (2026-05-11-frames-call): LoRA models for the snail across ages completed.
- 2026-05-18-frames-call – LoRA done; RAI CRITS chosen over Edit Mind (edit-mind) for the metadata-analysis workflow (2026-05-18-frames-call). At this point the snail-age LoRA work is marked complete.
- 2026-06-01-frames-call – LoRA still referenced as part of the AI generation / character-consistency workstream (2026-06-01-frames-call).
LoRA work on the snail is a throughline of the AI generation pipeline (ai-agent-pipeline) – the character-consistency backbone that lets the snail appear across eras while still reading as the same character.
