LocalLLaMA debates character finetuning data strategies

The LocalLLaMA community is debating the most effective ways to source data for finetuning AI characters, weighing the trade-offs between manual crafting, web scraping, and synthetic generation using teacher models. The discussion highlights a shift toward high-quality "golden" seed sets combined with synthetic scaling to maintain character consistency.

// ANALYSIS

While synthetic data offers unparalleled scale, the consensus emphasizes that a small, hand-crafted "golden" dataset is still required to maintain unique character voice and avoid model collapse.

–Synthetic generation using teacher models like GPT-4 or Claude 3.5 is now the standard for volume.
–Scraping remains vital for existing media characters but requires sophisticated LLM cleaning to be usable.
–"Golden sets" of 20-50 perfect examples are the secret sauce for preventing generic AI personality bleed.
–Tools like Unsloth and Axolotl continue to dominate the local fine-tuning pipeline.
