Thanks for asking me to work on this. I will get started on it and keep this PR's description up to date as I form a plan and make progress.

im getting this error when trying to access my tlog report:

⚠️ AI generation failed: OpenAI API error (400): {
"error": {
"message": "This model's maximum context length is 128000 tokens. However, you requested 128350 tokens (127450 in the messages, 900 in the completion). Please reduce the length of the messages or completion.",
"type": "invalid_request_error",
"param": "messages",
"code": "context_length_exceeded"
}
}

please fix this!
