The premise
Instruct models are the default for chat, but base models win for completion-style tasks and custom tuning.
What AI does well here
- Use base models for completion-style, deterministic tasks.
- Use instruct for assistants, dialogue, and tool use.
- Fine-tune base when you need a domain-specific model.
What AI cannot do
- Use base models conversationally without scaffolding.
- Easily make instruct models stop being chatty.
