What happened: Three Tests to Run Before You Switch from LoRA to FullFT

Fireworks AI tested whether LoRA gaps versus full fine-tuning stem from data coverage, learning rate tuning, or adapter rank limits.

Why it matters: Three Tests to Run Before You Switch from LoRA to FullFT

Engineers choosing between LoRA and full fine-tuning should run these three tests before assuming full fine-tuning is necessary.

Test results are task-specific on Qwen3.5-9B; findings may not generalize to other models, domains, or your specific use case.
