You can somewhat counteract this with the **Summary Verbosity** option.\n\n**Lowering the number here will also *slightly* increase the cost of the summarization step**, both because you're getting more summarization data and because the summarization prompt's system instructions will be sent more times.\n\nDefaults to 2,750 tokens. The maximum value is 5,000 tokens (2,750 for gpt-3.5-turbo, which has a 4,096-token limit that includes the completion and system instruction tokens), and the minimum value is 500 tokens.\n\nIf you're using an OpenAI trial account and haven't added your billing info yet, note that you may get rate-limited due to the low requests-per-minute (RPM) rate on trial accounts.`,
