Tips & Best Practices

Optimizing ML Parameter Search

For a good balance between speed and cost, a duration of 20-30 minutes for an experiment cycle (including parameter searching) is recommended. This allows sufficient exploration without excessive expenditure.

Prompt Templating

Use Jinja2-like syntax (e.g., {{ variable_name }}) in llm_generate nodes to dynamically inject values from the shared context.

Debugging with CLI

Use gemini -r, qwen -c, or opencode -c inside an experiment directory to inspect the exact prompt sent to the LLM and resume the conversation manually if needed.

CLI Hygiene

Set your global CLI history file (e.g., ~/gemini/GEMINI.md) to Read-Only to prevent context pollution between different projects.
