Domain-Specific Fine-Tuning: How to Build a Model That Thinks Like a DeFi Native
GRPO dethroned PPO. QLoRA + Unsloth makes 7B fine-tuning trivial on a single GPU. The SLM-as-specialist trend means you can now build a model that outperforms GPT-4 on DeFi protocol analysis at 1% of the inference cost. Here is the full 2026 fine-tuning landscape — and the Analyst agent we are adding to Hydra.
