Our agent only answers this when asked any question in MS Teams:

Ein Fehler ist aufgetreten. Fehlercode: OpenAIModelTokenLimit Unterhaltungs-ID: a:10HMwIRZDblnnzYKSeWIHUrx5RddpmuaOhX1U8S386qmDnODyEvvDeI89f90DyD4pgLi8O-DFpguq7A9j87YO8R2A-byLJm3u4LnUZCs-bR1lBusNfAVOynAOvRHOXwAA Zeit (UTC): 2026-05-11T08:15:31.377Z.

I already tried "start over", "Neustart", starting a new chat in MS Teams, restarting teams but that didn't solve the problem.

How can we continue using that agent in MS Teams?

How can we assure that this doesn't happen in future to any of our employees?

Best,

Reiner

Hi @RS-07050956-0,

Are you by any chance using an AI model? Like maybe using a GPT or a Gemini model or an AI Builder to perform a certain task? Based on your error response, it appears the error is due to the OpenAI Model Token Limit. This means you have exhausted your valid tokens for the model.

When using an AI model, we basically communicate with the LLM using API requests. Each API request contains an input JSON, which is the system instructions and your prompt, and an output JSON, which is the model's response to your prompt. And both input and output JSONs consume tokens based on the number of characters used. So larger input instructions and prompts will consume more input tokens, and larger responses consume more output tokens.

Based on your error code, it seems you have reached your model's limit. You can either wait for your limit to reset or you can upgrade your model to allow for greater tokens.

Quick tip: Try to keep your input instructions small and use a prompt that tells the model to minimize the output response, if possible, to optimize the token consumption.
