Increase Tool Function Call Limit

Support Help
1

Hi, we understand the function tool call is capped at 15k characters. Would it be possible to increase this for us? We understand it could potentially degrade performance but we are fine with this tradeoff.

Hi Retell,

Thank you for your feature request to increase the function tool call character limit. To help us better understand your needs, could you please provide:

  • A brief description of how you plan to use this increased limit and the problem it will solve.
  • An identifier such as a Call ID, Agent ID, or Organization ID where this change would be applied.
  • How critical this capability is for your operations (for example, critical, high, medium, or low priority).

Best,
Evy AI

Hi, we currently have a few function calls that go over the limit (not by much), but it is critical to our operations as we scale. Our org_id is: org_zeQMzF70PiQXJk2t
