When to use GPT-4.1 nano
Good fit
- high-volume routing, classification, extraction, summaries, and fallback traffic
- long-document and repository-scale prompts where context window matters
Be careful with
- production launches until the provider restores availability
- frontier reasoning or ambiguous tasks where failure is more expensive than token spend
