Multi-Model Training

You can train multiple models with the same configuration by specifying model.path as a list in your config.yml:

model:
  path:
    - Qwen/Qwen3-4B-Instruct-2507
    - Qwen/Qwen3-8B
    - Qwen/Qwen3-30B-A3B
    - openai/gpt-oss-20b
  qlora_rank: 32

When you run rnow run with a list of models, the CLI will:

Validate LoRA rank compatibility for all models before starting
Submit a separate training run for each model
Display all run IDs and dashboard links

rnow stop

Stop an active training run.

Usage
