Leverage the 128K context window: Include all relevant context in a single request instead of making multiple smaller calls.
Set token limits: Control output length with max_tokens to avoid surprise costs on verbose responses.
Batch requests: Process multiple items in a single prompt to reduce per-request overhead.
Monitor usage: Track your API usage to identify cost spikes and optimize patterns.
