Qwen2.5 72B Instruct can be fine-tuned on your data to create a model with better response quality. Fireworks uses low-rank adaptation (LoRA) to train a model that can be served efficiently at inference time.
See the Fine-tuning guide for details.
On-demand deployments allow you to use Qwen2.5 72B Instruct on dedicated GPUs with Fireworks' high-performance serving stack with high reliability and no rate limits.
