Fine-tuning
Train models that know your domain inside out
Adapt frontier models to your specific vocabulary, tone, and tasks. Hanzo's fine-tuning pipeline handles data prep, distributed training, and deployment — all on your infrastructure.
What's included
Every feature you need to ship fast and scale confidently.
Supervised Fine-tuning (SFT)
Full fine-tuning and LoRA/QLoRA adapters. Train on instruction-response pairs with your own data.
RLHF & DPO
Align models to human preferences with reinforcement learning or direct preference optimization.
Data Flywheel
Capture production traffic, curate high-quality examples, and continuously improve your models.
On-premise Training
Train on your GPUs — NVIDIA H100, A100, or L40S. Data never leaves your VPC.
Evaluation Suite
Automated evals against domain benchmarks before every deployment. Catch regression before it ships.
Adapter Management
Version, tag, and serve multiple LoRA adapters on a single base model. Switch at inference time.
Use cases
